Typography 1.1. Introduction There is a lot of software freely available for Unix-based systems, which is usually available in form of the source code. Before such software can be used, it needs to be configured to the local system, compiled and installed, and this is exactly what The NetBSD Packages Collection (pkgsrc) does. pkgsrc also has some basic commands to handle binary packages, so that not every user has to build the packages for himself, which is a time-costly task. pkgsrc currently contains several thousand packages, including: * www/apache - The Apache web server * www/firefox - The Firefox web browser * meta-pkgs/gnome - The GNOME Desktop Environment * meta-pkgs/kde3 - The K Desktop Environment ...just to name a few. pkgsrc has built-in support for handling varying dependencies, such as pthreads and X11, and extended features such as IPv6 support on a range of platforms. 1.1.1. Why pkgsrc? pkgsrc provides the following key features: * Easy building of software from source as well as the creation and installation of binary packages. The source and latest patches are retrieved from a master or mirror download site, checksum verified, then built on your system. Support for binary-only distributions is available for both native platforms and NetBSD emulated platforms. * All packages are installed in a consistent directory tree, including binaries, libraries, man pages and other documentation. * Package dependencies, including when performing package updates, are handled automatically. The configuration files of various packages are handled automatically during updates, so local changes are preserved. * Like NetBSD, pkgsrc is designed with portability in mind and consists of highly portable code. This allows the greatest speed of development when porting to new a platform. This portability also ensures that pkgsrc is consistent across all platforms. * The installation prefix, acceptable software licenses, international encryption requirements and build-time options for a large number of packages are all set in a simple, central configuration file. * The entire source (not including the distribution files) is freely available under a BSD license, so you may extend and adapt pkgsrc to your needs. Support for local packages and patches is available right out of the box, so you can configure it specifically for your environment. 1.1.2. Supported platforms pkgsrc consists of both a source distribution and a binary distribution for these operating systems. After retrieving the required source or binaries, you can be up and running with pkgsrc in just minutes! pkgsrc was derived from FreeBSD's ports system, and initially developed for NetBSD only. Since then, pkgsrc has grown a lot, and now supports the following platforms: Table 1.1. Platforms supported by pkgsrc +----------------------------------------------------------------+ | Platform |Date Support Added| |---------------------------------------------+------------------| |NetBSD | Aug 1997 | |---------------------------------------------+------------------| |Solaris | Mar 1999 | |---------------------------------------------+------------------| |Linux | Jun 1999 | |---------------------------------------------+------------------| |Darwin (Mac OS X) | Oct 2001 | |---------------------------------------------+------------------| |FreeBSD | Nov 2002 | |---------------------------------------------+------------------| |OpenBSD | Nov 2002 | |---------------------------------------------+------------------| |IRIX | Dec 2002 | |---------------------------------------------+------------------| |BSD/OS | Dec 2003 | |---------------------------------------------+------------------| |AIX | Dec 2003 | |---------------------------------------------+------------------| |Interix (Microsoft Windows Services for Unix)| Mar 2004 | |---------------------------------------------+------------------| |DragonFlyBSD | Oct 2004 | |---------------------------------------------+------------------| |OSF/1 | Nov 2004 | +----------------------------------------------------------------+ 1.2. Overview This document is divided into three parts. The first, The pkgsrc user's guide, describes how one can use one of the packages in the Package Collection, either by installing a precompiled binary package, or by building one's own copy using the NetBSD package system. The second part, The pkgsrc developer's guide, explains how to prepare a package so it can be easily built by other NetBSD users without knowing about the package's building details. The third part, The pkgsrc infrastructure internals is intended for those who want to understand how pkgsrc is implemented. This document is available in various formats: HTML, PDF, PS, TXT. 1.3. Terminology There has been a lot of talk about "ports", "packages", etc. so far. Here is a description of all the terminology used within this document. Package A set of files and building instructions that describe what's necessary to build a certain piece of software using pkgsrc. Packages are traditionally stored under /usr/pkgsrc. The NetBSD package system This is the former name of "pkgsrc". It is part of the NetBSD operating system and can be bootstrapped to run on non-NetBSD operating systems as well. It handles building (compiling), installing, and removing of packages. Distfile This term describes the file or files that are provided by the author of the piece of software to distribute his work. All the changes necessary to build on NetBSD are reflected in the corresponding package. Usually the distfile is in the form of a compressed tar-archive, but other types are possible, too. Distfiles are usually stored below /usr/pkgsrc/distfiles. Port This is the term used by FreeBSD and OpenBSD people for what we call a package. In NetBSD terminology, "port" refers to a different architecture. Precompiled/binary package A set of binaries built with pkgsrc from a distfile and stuffed together in a single .tgz file so it can be installed on machines of the same machine architecture without the need to recompile. Packages are usually generated in /usr/pkgsrc/packages; there is also an archive on ftp.NetBSD.org. Sometimes, this is referred to by the term "package" too, especially in the context of precompiled packages. Program The piece of software to be installed which will be constructed from all the files in the distfile by the actions defined in the corresponding package. 1.3.1. Commonly used abbreviations ICE Internal Compiler Error 1.3.2. Roles involved in pkgsrc pkgsrc users The pkgsrc users are people who use the packages provided by pkgsrc. Typically they are system administrators. The people using the software that is inside the packages (maybe called "end users") are not covered by the pkgsrc guide. There are two kinds of pkgsrc users: Some only want to install pre-built binary packages. Others build the pkgsrc packages from source, either for installing them directly or for building binary packages themselves. For pkgsrc users Part I, "The pkgsrc user's guide" should provide all necessary documentation. package maintainers A package maintainer creates packages as described in Part II, "The pkgsrc developer's guide". infrastructure developers These people are involved in all those files that live in the mk/ directory and below. Only these people should need to read through Part III, "The pkgsrc infrastructure internals", though others might be curious, too. 1.4. Typography When giving examples for commands, shell prompts are used to show if the command should/can be issued as root, or if "normal" user privileges are sufficient. We use a # for root's shell prompt, and a % for users' shell prompt, assuming they use the C-shell or tcsh. Part I. The pkgsrc user's guide Table of Contents 2.

Where to get pkgsrc and how to keep it up-to-date Table of Contents 2.1. Getting pkgsrc for the first time 2.1.1. As tar file 2.1.2. Via SUP 2.1.3. Via CVS 2.2. Keeping pkgsrc up-to-date 2.2.1. Via tar files 2.2.2. Via CVS The most common location where pkgsrc is installed is /usr/pkgsrc for the "package sources" and /usr/pkg for the installed binary packages. You are though free to install the sources and binary packages wherever you want in your filesystem, provided that both paths do not contain white-space or other characters that are interpreted specially by the shell and some other programs. A safe bet is to use only letters, digits, underscores and dashes in the names. 2.1. Getting pkgsrc for the first time Before you download any pkgsrc files, you should decide whether you want the current branch or the stable branch. The latter is forked on a quarterly basis from the current branch and only gets modified for security updates. The names of the stable branches are built from the year and the quarter, for example 2006Q1. The second step is to decide how you want to download pkgsrc. You can get it as a tar file, via SUP, or via CVS. All three ways are described here. 2.1.1. As tar file The primary download location for all pkgsrc files is ftp://ftp.NetBSD.org/pub/ pkgsrc/. There are a number of subdirectories for different purposes, which are described in detail in Appendix C, Directory layout of the pkgsrc FTP server. The tar file for the current branch is in the directory current and is called pkgsrc.tar.gz. It is autogenerated daily. The tar file for the stable branch 2006Q1 is in the directory 2006Q1 and is also called pkgsrc.tar.gz. After downloading the tar file, change to the directory where you want to have pkgsrc. This is usually /usr. Then, run tar xfz pkgsrc.tar.gz to extract the files. 2.1.2. Via SUP As an alternative to the tar file, you can get pkgsrc via the Software Update Protocol, SUP. To do so, make sure your supfile has a line release=pkgsrc in it, see the examples in /usr/share/examples/supfiles, and that the /usr/ pkgsrc directory exists. Then, simply run sup -v /path/to/your/supfile. 2.1.3. Via CVS To get pkgsrc via CVS, make sure you have cvs(1) installed. To do an initial (full) checkout of pkgsrc, you first have to set some environment variables. For the C-Shell, type: % setenv CVSROOT anoncvs@anoncvs.NetBSD.org:/cvsroot % setenv CVS_RSH ssh Or, the same for the bourne shell: $ CVSROOT="anoncvs@anoncvs.NetBSD.org:/cvsroot" $ CVS_RSH="ssh" $ export CVSROOT CVS_RSH Then, you change to the directory where you want to have your copy of pkgsrc. In most cases this is /usr. In that directory you run the checkout command, which is cvs -q checkout -P pkgsrc for the current branch and cvs -q checkout -rpkgsrc-2006Q1 -P pkgsrc for the stable branch. This command will create a directory called pkgsrc with all the pkgsrc files in it. 2.2. Keeping pkgsrc up-to-date The preferred way to keep pkgsrc up-to-date is via CVS (which also works if you have first installed it via a tar file). It saves bandwidth and hard disk activity, compared to downloading the tar file again. 2.2.1. Via tar files Warning When updating from a tar file, you first need to completely remove the old pkgsrc directory. Otherwise those files that have been removed from pkgsrc in the mean time will not be removed on your local disk, resulting in inconsistencies. When removing the old files, any changes that you have done to the pkgsrc files will be lost after updating. Therefore updating via CVS is strongly recommended. Note that by default the distfiles and the binary packages are saved in the pkgsrc tree, so don't forget to rescue them before updating. You can also configure pkgsrc to use other than the default directories by setting the DISTDIR and PACKAGES variables. See Chapter 5, Configuring pkgsrc for the details. To update pkgsrc from a tar file, download the tar file as explained above. Then, make sure that you have not made any changes to the files in the pkgsrc directory. Remove the pkgsrc directory and extract the new tar file. Done. 2.2.2. Via CVS To update pkgsrc via CVS, make sure the environment variable CVS_RSH is set as above. Then, change to the pkgsrc directory and run cvs -q update -dP. 2.2.2.1. Switching between different pkgsrc branches When updating pkgsrc, the CVS program keeps track of the branch you selected. But if you, for whatever reason, want to switch from the stable branch to the current one, you can do it by adding the option "-A" after the "update" keyword. To switch from the current branch back to the stable branch, add the "-rpkgsrc-2006Q1" option. 2.2.2.2. What happens to my changes when updating? When you update pkgsrc, the CVS program will only touch those files that are registered in the CVS repository. That means that any packages that you created on your own will stay unmodified. If you change files that are managed by CVS, later updates will try to merge your changes with those that have been done by others. See the CVS manual, chapter "update" for details. Chapter 3.

Bootstrapping pkgsrc Installing the bootstrap kit from source should be as simple as: # env CVS_RSH=ssh cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout pkgsrc # cd pkgsrc/bootstrap # ./bootstrap See Chapter 2, Where to get pkgsrc and how to keep it up-to-date for other ways to get pkgsrc before bootstrapping. The given bootstrap command will use the defaults of /usr/pkg for the prefix where programs will be installed in, and / var/db/pkg for the package database directory where pkgsrc will do its internal bookkeeping. However, these can also be set using command-line arguments. Binary packages for the pkgsrc tools and an initial set of packages is available for supported platforms. An up-to-date list of these can be found on www.pkgsrc.org. Note that this only works for privileged builds that install into /usr/pkg. Note The bootstrap installs a bmake tool. Use this bmake when building via pkgsrc. For examples in this guide, use bmake instead of "make". 3.3. Platform-specific notes Here are some platform-specific notes you should be aware of. 3.3.1. Darwin (Mac OS X) Darwin 5.x and 6.x are supported. There are two methods of using pkgsrc on Mac OS X, by using a disk image, or a UFS partition. Before you start, you will need to download and install the Mac OS X Developer Tools from Apple's Developer Connection. See http://developer.apple.com/macosx/ for details. Also, make sure you install X11 for Mac OS X and the X11 SDK from http://www.apple.com/macosx/x11/download/ if you intend to build packages that use the X11 Window System. If you already have a UFS partition, or have a spare partition that you can format as UFS, it is recommended to use that instead of the disk image. It'll be somewhat faster and will mount automatically at boot time, where you must manually mount a disk image. Note You cannot use a HFS+ file system for pkgsrc, because pkgsrc currently requires the file system to be case-sensitive, and HFS+ is not. 3.3.1.1. Using a disk image Create the disk image: # cd pkgsrc/bootstrap # ./ufsdiskimage create ~/Documents/NetBSD 512 # megabytes - season to taste # ./ufsdiskimage mount ~/Documents/NetBSD # sudo chown `id -u`:`id -g` /Volumes/NetBSD That's it! 3.3.1.2. Using a UFS partition By default, /usr will be on your root file system, normally HFS+. It is possible to use the default prefix of /usr/pkg by symlinking /usr/pkg to a directory on a UFS file system. Obviously, another symlink is required if you want to place the package database directory outside the prefix. e.g. # ./bootstrap --pkgdbdir /usr/pkg/pkgdb If you created your partitions at the time of installing Mac OS X and formatted the target partition as UFS, it should automatically mount on /Volumes/ when the machine boots. If you are (re)formatting a partition as UFS, you need to ensure that the partition map correctly reflects "Apple_UFS" and not "Apple_HFS". The problem is that none of the disk tools will let you touch a disk that is booted from. You can unmount the partition, but even if you newfs it, the partition type will be incorrect and the automounter won't mount it. It can be mounted manually, but it won't appear in Finder. You'll need to boot off of the OS X Installation (User) CD. When the Installation program starts, go up to the menu and select Disk Utility. Now, you will be able to select the partition you want to be UFS, and Format it Apple UFS. Quit the Disk Utility, quit the installer which will reboot your machine. The new UFS file system will appear in Finder. Be aware that the permissions on the new file system will be writable by root only. This note is as of 10.2 (Jaguar) and applies to earlier versions. Hopefully Apple will fix Disk Utility in 10.3 (Panther). 3.3.2. FreeBSD FreeBSD 4.7 and 5.0 have been tested and are supported, other versions may work. Care should be taken so that the tools that this kit installs do not conflict with the FreeBSD userland tools. There are several steps: 1. FreeBSD stores its ports pkg database in /var/db/pkg. It is therefore recommended that you choose a different location (e.g. /usr/pkgdb) by using the --pkgdbdir option to the bootstrap script. 2. If you do not intend to use the FreeBSD ports tools, it's probably a good idea to move them out of the way to avoid confusion, e.g. # cd /usr/sbin # mv pkg_add pkg_add.orig # mv pkg_create pkg_create.orig # mv pkg_delete pkg_delete.orig # mv pkg_info pkg_info.orig 3. An example /etc/mk.conf file will be placed in /etc/mk.conf.example file when you use the bootstrap script. 3.3.3. Interix Interix is a POSIX-compatible subsystem for the Windows NT kernel, providing a Unix-like environment with a tighter kernel integration than available with Cygwin. It is part of the Windows Services for Unix package, available for free for any licensed copy of Windows 2000, XP (not including XP Home), or 2003. SFU can be downloaded from http://www.microsoft.com/windows/sfu/. Services for Unix 3.5, current as of this writing, has been tested. 3.0 or 3.1 may work, but are not officially supported. (The main difference in 3.0/3.1 is lack of pthreads.) 3.3.3.1. When installing Interix/SFU At an absolute minimum, the following packages must be installed from the Windows Services for Unix 3.5 distribution in order to use pkgsrc: * Utilities -> Base Utilities * Interix GNU Components -> (all) * Remote Connectivity * Interix SDK When using pkgsrc on Interix, DO NOT install the Utilities subcomponent "UNIX Perl". That is Perl 5.6 without shared module support, installed to /usr/local, and will only cause confusion. Instead, install Perl 5.8 from pkgsrc (or from a binary package). The Remote Connectivity subcomponent "Windows Remote Shell Service" does not need to be installed, but Remote Connectivity itself should be installed in order to have a working inetd. During installation you may be asked whether to enable setuid behavior for Interix programs, and whether to make pathnames default to case-sensitive. Setuid should be enabled, and case-sensitivity MUST be enabled. (Without case-sensitivity, a large number of packages including perl will not build.) NOTE: Newer Windows service packs change the way binary execution works (via the Data Execution Prevention feature). In order to use pkgsrc and other gcc-compiled binaries reliably, a hotfix containing POSIX.EXE, PSXDLL.DLL, PSXRUN.EXE, and PSXSS.EXE (899522 or newer) must be installed. Hotfixes are available from Microsoft through a support contract; however, a NetBSD developer has made most Interix hotfixes available for personal use from http:/ /www.duh.org/interix/hotfixes.php. 3.3.3.2. What to do if Interix/SFU is already installed If SFU is already installed and you wish to alter these settings to work with pkgsrc, note the following things. * To uninstall UNIX Perl, use Add/Remove Programs, select Microsoft Windows Services for UNIX, then click Change. In the installer, choose Add or Remove, then uncheck Utilities->UNIX Perl. * To enable case-sensitivity for the file system, run REGEDIT.EXE, and change the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\kernel Set the DWORD value "obcaseinsensitive" to 0; then reboot. * To enable setuid binaries (optional), run REGEDIT.EXE, and change the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Services for UNIX Set the DWORD value "EnableSetuidBinaries" to 1; then reboot. 3.3.3.3. Important notes for using pkgsrc The package manager (either the pkgsrc "su" user, or the user running "pkg_add") must be a member of the local Administrators group. Such a user must also be used to run the bootstrap. This is slightly relaxed from the normal pkgsrc requirement of "root". The package manager should use a umask of 002. "make install" will automatically complain if this is not the case. This ensures that directories written in /var/db/pkg are Administrators-group writeable. The popular Interix binary packages from http://www.interopsystems.com/ use an older version of pkgsrc's pkg_* tools. Ideally, these should NOT be used in conjunction with pkgsrc. If you choose to use them at the same time as the pkgsrc packages, ensure that you use the proper pkg_* tools for each type of binary package. The TERM setting used for DOS-type console windows (including those invoked by the csh and ksh startup shortcuts) is "interix". Most systems don't have a termcap/terminfo entry for it, but the following .termcap entry provides adequate emulation in most cases: interix:kP=\E[S:kN=\E[T:kH=\E[U:dc@:DC@:tc=pcansi: 3.3.3.4. Limitations of the Interix platform Though Interix suffices as a familiar and flexible substitute for a full Unix-like platform, it has some drawbacks that should be noted for those desiring to make the most of Interix. * X11: Interix comes with the standard set of X11R6 client libraries, and can run X11 based applications, but it does not come with an X server. Some options are StarNet X-Win32, Hummingbird Exceed (available in a trimmed version for Interix from Interop Systems as the Interop X Server), and the free X11 server included with Cygwin. Also, StarNet Communications has graciously provided a free version of their X-Win32 product that accepts connections only from localhost: X-Win32 LX, recommended by the maintainer of Interix pkgsrc support. * X11 acceleration: Because Interix runs in a completely different NT subsystem from Win32 applications, it does not currently support various X11 protocol extensions for acceleration (such as MIT-SHM or DGA). Most interactive applications to a local X server will run reasonably fast, but full motion video and other graphics intensive applications may require a faster-than-expected CPU. * Audio: Interix has no native support for audio output. For audio support, pkgsrc uses the esound client/server audio system on Interix. Unlike on most platforms, the audio/esound package does not contain the esd server component. To output audio via an Interix host, the emulators/cygwin_esound package must also be installed. * CD/DVDs, USB, and SCSI: Direct device access is not currently supported in Interix, so it is not currently possible to access CD/DVD drives, USB devices, or SCSI devices through non-filesystem means. Among other things, this makes it impossible to use Interix directly for CD/DVD burning. * Tape drives: Due to the same limitations as for CD-ROMs and SCSI devices, tape drives are also not directly accessible in Interix. However, support is in work to make tape drive access possible by using Cygwin as a bridge (similarly to audio bridged via Cygwin's esound server). 3.3.3.5. Known issues for pkgsrc on Interix It is not necessary, in general, to have a "root" user on the Windows system; any member of the local Administrators group will suffice. However, some packages currently assume that the user named "root" is the privileged user. To accommodate these, you may create such a user; make sure it is in the local group Administrators (or your language equivalent). "pkg_add" creates directories of mode 0755, not 0775, in $PKG_DBDIR. For the time being, install packages as the local Administrator (or your language equivalent), or run the following command after installing a package to work around the issue: # chmod -R g+w $PKG_DBDIR 3.3.4. IRIX You will need a working C compiler, either gcc or SGI's MIPS and MIPSpro compiler (cc/c89). Please set the CC environment variable according to your preference. If you do not have a license for the MIPSpro compiler suite, you can download a gcc tardist file from http://freeware.sgi.com/. Please note that you will need IRIX 6.5.17 or higher, as this is the earliest version of IRIX providing support for if_indextoname(3), if_nametoindex(3), etc. At this point in time, pkgsrc only supports one ABI at a time. That is, you can not switch between the old 32-bit ABI, the new 32-bit ABI and the 64-bit ABI. If you start out using "abi=n32", that's what all your packages will be built with. Therefore, please make sure that you have no conflicting CFLAGS in your environment or the /etc/mk.conf. Particularly, make sure that you do not try to link n32 object files with lib64 or vice versa. Check your /etc/ compiler.defaults! If you have the actual pkgsrc tree mounted via NFS from a different host, please make sure to set WRKOBJDIR to a local directory, as it appears that IRIX linker occasionally runs into issues when trying to link over a network-mounted file system. The bootstrapping process should set all the right options for programs such as imake(1), but you may want to set some options depending on your local setup. Please see pkgsrc/mk/defaults/mk.conf and, of course, your compiler's man pages for details. If you are using SGI's MIPSPro compiler, please set PKGSRC_COMPILER= mipspro in /etc/mk.conf. Otherwise, pkgsrc will assume you are using gcc and may end up passing invalid flags to the compiler. Note that bootstrap should create an appropriate mk.conf.example by default. If you have both the MIPSPro compiler chain installed as well as gcc, but want to make sure that MIPRPro is used, please set your PATH to not include the location of gcc (often /usr/freeware/bin), and (important) pass the '--preserve-path' flag. 3.3.5. Linux Some versions of Linux (for example Debian GNU/Linux) need either libtermcap or libcurses (libncurses). Installing the distributions libncurses-dev package (or equivalent) should fix the problem. pkgsrc supports both gcc (GNU Compiler Collection) and icc (Intel C++ Compiler). gcc is the default. icc 8.0 and 8.1 on i386 have been tested. To bootstrap using icc, assuming the default icc installation directory: env CC=/opt/intel_cc_80/bin/icc LDFLAGS=-static-libcxa \ ac_cv___attribute__=yes ./bootstrap Note icc 8.1 needs the `-i-static' argument instead of -static-libcxa. icc supports __attribute__, but the GNU configure test uses a nested function, which icc does not support. #undef'ing __attribute__ has the unfortunate side-effect of breaking many of the Linux header files, which cannot be compiled properly without __attribute__. The test must be overridden so that __attribute__ is assumed supported by the compiler. After bootstrapping, you should set PKGSRC_COMPILER in /etc/mk.conf: PKGSRC_COMPILER= icc The default installation directory for icc is /opt/intel_cc_80, which is also the pkgsrc default. If you have installed it into a different directory, set ICCBASE in /etc/mk.conf: ICCBASE= /opt/icc pkgsrc uses the static linking method of the runtime libraries provided by icc, so binaries can be run on other systems which do not have the shared libraries installed. Libtool, however, extracts a list of libraries from the ld(1) command run when linking a C++ shared library and records it, throwing away the -Bstatic and -Bdynamic options interspersed between the libraries. This means that libtool-linked C++ shared libraries will have a runtime dependency on the icc libraries until this is fixed in libtool. 3.3.6. OpenBSD OpenBSD 3.0 and 3.2 are tested and supported. Care should be taken so that the tools that this kit installs do not conflict with the OpenBSD userland tools. There are several steps: 1. OpenBSD stores its ports pkg database in /var/db/pkg. It is therefore recommended that you choose a different location (e.g. /usr/pkgdb) by using the --pkgdbdir option to the bootstrap script. 2. If you do not intend to use the OpenBSD ports tools, it's probably a good idea to move them out of the way to avoid confusion, e.g. # cd /usr/sbin # mv pkg_add pkg_add.orig # mv pkg_create pkg_create.orig # mv pkg_delete pkg_delete.orig # mv pkg_info pkg_info.orig 3. An example /etc/mk.conf file will be placed in /etc/mk.conf.example file when you use the bootstrap script. OpenBSD's make program uses /etc/mk.conf as well. You can work around this by enclosing all the pkgsrc-specific parts of the file with: .ifdef BSD_PKG_MK # pkgsrc stuff, e.g. insert defaults/mk.conf or similar here .else # OpenBSD stuff .endif 3.3.7. Solaris Solaris 2.6 through 9 are supported on both x86 and sparc. You will need a working C compiler. Both gcc 2.95.3 and Sun WorkShop 5 have been tested. The following packages are required on Solaris 8 for the bootstrap process and to build packages. * SUNWsprot * SUNWarc * SUNWbtool * SUNWtoo * SUNWlibm Please note that the use of GNU binutils on Solaris is not supported, as of June 2006. Whichever compiler you use, please ensure the compiler tools and your $prefix are in your PATH. This includes /usr/ccs/{bin,lib} and e.g. /usr/pkg/ {bin,sbin}. 3.3.7.1. If you are using gcc It makes life much simpler if you only use the same gcc consistently for building all packages. It is recommended that an external gcc be used only for bootstrapping, then either build gcc from lang/gcc or install a binary gcc package, then remove gcc used during bootstrapping. Binary packages of gcc can be found through http://www.sun.com/bigadmin/common/ freewareSearch.html. 3.3.7.2. If you are using Sun WorkShop You will need at least the following packages installed (from WorkShop 5.0) * SPROcc - Sun WorkShop Compiler C 5.0 * SPROcpl - Sun WorkShop Compiler C++ 5.0 * SPROild - Sun WorkShop Incremental Linker * SPROlang - Sun WorkShop Compilers common components You should set CC, CXX and optionally, CPP in /etc/mk.conf, e.g.: CC= cc CXX= CC CPP= /usr/ccs/lib/cpp 3.3.7.3. Buildling 64-bit binaries with SunPro Building 64-bit binaries is a little trickier. First, you need to bootstrap pkgsrc in 64-bit mode. One problem here is that while building one of the programs in the bootstrap kit (bmake), the CFLAGS variable is not honored, even if it is set in the environment. To work around this bug, you can create a simple shell script called cc64 and put it somewhere in the PATH: #! /bin/sh exec /opt/SUNWspro/bin/cc -xtarget=ultra -xarch=v9 ${1+"$@"} Then, pass the definition for CC in the environment of the bootstrap command: $ cd bootstrap $ CC=cc64 ./bootstrap After bootstrapping, there are two alternative ways, depending on whether you want to find bugs in packages or get your system ready quickly. If you just want a running system, add the following lines to your mk.conf file: CC= cc64 CXX= CC64 PKGSRC_COMPILER= sunpro This way, all calls to the compiler will be intercepted by the above wrapper and therefore get the necessary ABI options automatically. (Don't forget to create the shell script CC64, too.) To find packages that ignore the user-specified CFLAGS and CXXFLAGS, add the following lines to your mk.conf file: CC= cc CXX= CC PKGSRC_COMPILER= sunpro CFLAGS= -xtarget=ultra -xarch=v9 CXXFLAGS= -xtarget=ultra -xarch=v9 LDFLAGS= -xtarget=ultra -xarch=v9 Packages that don't use the flags provided in the configuration file will try to build 32-bit binaries and fail during linking. Detecting this is useful to prevent bugs on other platforms where the error would not show up but pass silently. 3.3.7.4. Common problems Sometimes, when using libtool, /bin/ksh crashes with a segmentation fault. The workaround is to use another shell for the configure scripts, for example by installing shells/bash and adding the following lines to your mk.conf: CONFIG_SHELL= ${LOCALBASE}/bin/bash WRAPPER_SHELL= ${LOCALBASE}/bin/bash Then, rebuild the devel/libtool-base package.

Selecting the compiler Basically, there are two ways of using pkgsrc. The first is to only install the package tools and to use binary packages that someone else has prepared. This is the "pkg" in pkgsrc. The second way is to install the "src" of pkgsrc, too. Then you are able to build your own packages, and you can still use binary packages from someone else. 4.1. Using binary packages To use binary packages, you need some tools to manage them. On NetBSD, these tools are already installed. On all other operating systems, you need to install them first. For the following platforms, prebuilt versions of the package tools are available and can simply be downloaded and unpacked in the / directory: +------------------------------------------------------------------------+ | Platform | URL | |----------+-------------------------------------------------------------| |Solaris 9 |ftp://ftp0.mh.bbc.co.uk/pub/pkgsrc/packages/bootstrap-pkgsrc/| |----------+-------------------------------------------------------------| |Solaris 10|http://public.enst.fr/pkgsrc/packages/bootstrap-pkgsrc/ | +------------------------------------------------------------------------+ These pre-built package tools use /usr/pkg for the base directory, and /var/db/ pkg for the database of installed packages. If you cannot use these directories for whatever reasons (maybe because you're not root), you have to build the package tools yourself, which is explained in Section 3.2, "Bootstrapping pkgsrc". 4.1.1. Finding binary packages To install binary packages, you first need to know from where to get them. You can get them on CD-ROMs, DVDs, or via FTP or HTTP. The binary packages can be found at the following locations. +-------------------------------------------------------+ | Platform | URL | |----------+--------------------------------------------| |NetBSD |ftp://ftp.NetBSD.org/pub/NetBSD/packages/ | |----------+--------------------------------------------| |Solaris 9 |ftp://ftp0.mh.bbc.co.uk/pub/pkgsrc/packages/| |----------+--------------------------------------------| |Solaris 10|http://public.enst.fr/pkgsrc/packages/ | +-------------------------------------------------------+ Most of these directories contain binary packages for multiple platforms. Select the appropriate subdirectories, according to your machine architecture and operating system, until you find a directory called All. This directory contains all the binary packages. Further, there are subdirectories for categories that contain symbolic links that point to the actual binary package in ../All. This directory layout is used for all package repositories, no matter if they are accessed via HTTP, FTP, NFS, CD-ROM, or the local filesystem. 4.1.2. Installing binary packages If you have the files on a CD-ROM or downloaded them to your hard disk, you can install them with the following command (be sure to su to root first): # pkg_add /path/to/package.tgz If you have FTP access and you don't want to download the packages via FTP prior to installation, you can do this automatically by giving pkg_add an FTP URL: # pkg_add ftp://ftp.NetBSD.org/pub/NetBSD/packages///All/package Note that any prerequisite packages needed to run the package in question will be installed, too, assuming they are present where you install from. To save some typing, you can set the PKG_PATH environment variable to a semicolon-separated list of paths (including remote URLs); trailing slashes are not allowed. Additionally to the All directory there exists a vulnerable directory to which binary packages with known vulnerabilities are moved, since removing them could cause missing dependencies. To use these packages, add the vulnerable directory to your PKG_PATH. However, you should run security/audit-packages regularly, especially after installing new packages, and verify that the vulnerabilities are acceptable for your configuration. An example PKG_PATH would be: ftp:// ftp.NetBSD.org/pub/NetBSD/packages///All;ftp://ftp.NetBSD.org/ pub/NetBSD/packages///vulnerable Please note that semicolon (';') is a shell meta-character, so you'll probably have to quote it. After you've installed packages, be sure to have /usr/pkg/bin and /usr/pkg/sbin in your PATH so you can actually start the just installed program. 4.1.3. Deinstalling packages To deinstall a package, it does not matter whether it was installed from source code or from a binary package. The pkg_delete command does not know it anyway. To delete a package, you can just run pkg_delete package-name. The package name can be given with or without version number. Wildcards can also be used to deinstall a set of packages, for example *emacs*. Be sure to include them in quotes, so that the shell does not expand them before pkg_delete sees them. The -r option is very powerful: it removes all the packages that require the package in question and then removes the package itself. For example: # pkg_delete -r jpeg will remove jpeg and all the packages that used it; this allows upgrading the jpeg package. 4.1.4. Getting information about installed packages The pkg_info shows information about installed packages or binary package files. 4.1.5. Checking for security vulnerabilities in installed packages The NetBSD Security-Officer and Packages Groups maintain a list of known security vulnerabilities to packages which are (or have been) included in pkgsrc. The list is available from the NetBSD FTP site at ftp://ftp.NetBSD.org/ pub/pkgsrc/distfiles/vulnerabilities. Through security/audit-packages, this list can be downloaded automatically, and a security audit of all packages installed on a system can take place. There are two components to security/audit-packages. The first component, "download-vulnerability-list", is for downloading the list of vulnerabilities from the NetBSD FTP site. The second component, "audit-packages", checks to see if any of your installed packages are vulnerable. If a package is vulnerable, you will see output similar to the following: Package samba-2.0.9 has a local-root-shell vulnerability, see http://www.samba.org/samba/whatsnew/macroexploit.html One can set up security/audit-packages to download the vulnerabilities file daily, and include a package audit in the daily security script. Details on this are located in the MESSAGE file for security/audit-packages. 4.1.6. Finding if newer versions of your installed packages are in pkgsrc Install pkgtools/pkglint and run lintpkgsrc with the "-i" argument to check if your packages are up-to-date, e.g. % lintpkgsrc -i ... Version mismatch: 'tcsh' 6.09.00 vs 6.10.00 You can then use make update to update the package on your system and rebuild any dependencies. 4.1.7. Other administrative functions The pkg_admin executes various administrative functions on the package system. 4.1.8. A word of warning Please pay very careful attention to the warnings expressed in the pkg_add(1) manual page about the inherent dangers of installing binary packages which you did not create yourself, and the security holes that can be introduced onto your system by indiscriminate adding of such files. The same warning of course applies to every package you install from source when you haven't completely read and understood the source code of the package, the compiler that is used to build the package and all the other tools that are involved. 4.2. Building packages from source After obtaining pkgsrc, the pkgsrc directory now contains a set of packages, organized into categories. You can browse the online index of packages, or run make readme from the pkgsrc directory to build local README.html files for all packages, viewable with any web browser such as www/lynx or www/firefox. The default prefix for installed packages is /usr/pkg. If you wish to change this, you should do so by setting LOCALBASE in mk.conf. You should not try to use multiple different LOCALBASE definitions on the same system (inside a chroot is an exception). The rest of this chapter assumes that the package is already in pkgsrc. If it is not, see Part II, "The pkgsrc developer's guide" for instructions how to create your own packages. 4.2.1. Requirements To build packages from source, you need a working C compiler. On NetBSD, you need to install the "comp" and the "text" distribution sets. If you want to build X11-related packages, the "xbase" and "xcomp" distribution sets are required, too. 4.2.2. Fetching distfiles The first step for building a package is downloading the distfiles (i.e. the unmodified source). If they have not yet been downloaded, pkgsrc will fetch them automatically. If you have all files that you need in the distfiles directory, you don't need to connect. If the distfiles are on CD-ROM, you can mount the CD-ROM on /cdrom and add: DISTDIR=/cdrom/pkgsrc/distfiles to your mk.conf. You can overwrite some of the major distribution sites to fit to sites that are close to your own. Have a look at pkgsrc/mk/defaults/mk.conf to find some examples ? in particular, look for the MASTER_SORT, MASTER_SORT_REGEX and INET_COUNTRY definitions. This may save some of your bandwidth and time. You can change these settings either in your shell's environment, or, if you want to keep the settings, by editing the /etc/mk.conf file, and adding the definitions there. If a package depends on many other packages (such as meta-pkgs/kde3), the build process may alternate between periods of downloading source, and compiling. To ensure you have all the source downloaded initially you can run the command: % make fetch-list | sh which will output and run a set of shell commands to fetch the necessary files into the distfiles directory. You can also choose to download the files manually. 4.2.3. How to build and install Once the software has downloaded, any patches will be applied, then it will be compiled for you. This may take some time depending on your computer, and how many other packages the software depends on and their compile time. Note If using bootstrap or pkgsrc on a non-NetBSD system, use the pkgsrc bmake command instead of "make" in the examples in this guide. For example, type % cd misc/figlet % make at the shell prompt to build the various components of the package. The next stage is to actually install the newly compiled program onto your system. Do this by entering: % make install while you are still in the directory for whatever package you are installing. Installing the package on your system may require you to be root. However, pkgsrc has a just-in-time-su feature, which allows you to only become root for the actual installation step. That's it, the software should now be installed and setup for use. You can now enter: % make clean to remove the compiled files in the work directory, as you shouldn't need them any more. If other packages were also added to your system (dependencies) to allow your program to compile, you can tidy these up also with the command: % make clean-depends Taking the figlet utility as an example, we can install it on our system by building as shown in Appendix B, Build logs. The program is installed under the default root of the packages tree - /usr/ pkg. Should this not conform to your tastes, set the LOCALBASE variable in your environment, and it will use that value as the root of your packages tree. So, to use /usr/local, set LOCALBASE=/usr/local in your environment. Please note that you should use a directory which is dedicated to packages and not shared with other programs (i.e., do not try and use LOCALBASE=/usr). Also, you should not try to add any of your own files or directories (such as src/, obj/, or pkgsrc/) below the LOCALBASE tree. This is to prevent possible conflicts between programs and other files installed by the package system and whatever else may have been installed there. Some packages look in /etc/mk.conf to alter some configuration options at build time. Have a look at pkgsrc/mk/defaults/mk.conf to get an overview of what will be set there by default. Environment variables such as LOCALBASE can be set in /etc/mk.conf to save having to remember to set them each time you want to use pkgsrc. Occasionally, people want to "look under the covers" to see what is going on when a package is building or being installed. This may be for debugging purposes, or out of simple curiosity. A number of utility values have been added to help with this. 1. If you invoke the make(1) command with PKG_DEBUG_LEVEL=2, then a huge amount of information will be displayed. For example, make patch PKG_DEBUG_LEVEL=2 will show all the commands that are invoked, up to and including the "patch" stage. 2. If you want to know the value of a certain make(1) definition, then the VARNAME definition should be used, in conjunction with the show-var target. e.g. to show the expansion of the make(1) variable LOCALBASE: % make show-var VARNAME=LOCALBASE /usr/pkg % If you want to install a binary package that you've either created yourself (see next section), that you put into pkgsrc/packages manually or that is located on a remote FTP server, you can use the "bin-install" target. This target will install a binary package - if available - via pkg_add(1), else do a make package. The list of remote FTP sites searched is kept in the variable BINPKG_SITES, which defaults to ftp.NetBSD.org. Any flags that should be added to pkg_add(1) can be put into BIN_INSTALL_FLAGS. See pkgsrc/mk/defaults/mk.conf for more details. A final word of warning: If you set up a system that has a non-standard setting for LOCALBASE, be sure to set that before any packages are installed, as you can not use several directories for the same purpose. Doing so will result in pkgsrc not being able to properly detect your installed packages, and fail miserably. Note also that precompiled binary packages are usually built with the default LOCALBASE of /usr/pkg, and that you should not install any if you use a non-standard LOCALBASE. 4.2.4. Selecting the compiler By default, pkgsrc will use GCC to build packages. This may be overridden by setting the following variables in /etc/mk.conf: PKGSRC_COMPILER: This is a list of values specifying the chain of compilers to invoke when building packages. Valid values are: * distcc: distributed C/C++ (chainable) * ccache: compiler cache (chainable) * gcc: GNU C/C++ Compiler * mipspro: Silicon Graphics, Inc. MIPSpro (n32/n64) * mipspro: Silicon Graphics, Inc. MIPSpro (o32) * sunpro: Sun Microsystems, Inc. WorkShip/Forte/Sun ONE Studio The default is "gcc". You can use ccache and/or distcc with an appropriate PKGSRC_COMPILER setting, e.g. "ccache gcc". This variable should always be terminated with a value for a real compiler. GCC_REQD: This specifies the minimum version of GCC to use when building packages. If the system GCC doesn't satisfy this requirement, then pkgsrc will build and install one of the GCC packages to use instead. Chapter 5. Configuring pkgsrc Table of Contents 5.1. General configuration 5.2. Variables affecting the build process 5.3. Selecting and configuring the compiler 5.3.1. Additional flags to the compiler (CFLAGS) 5.4. Developer/advanced settings 5.5. Selecting Build Options 5.1. General configuration In this section, you can find some variables that apply to all pkgsrc packages. The preferred method of setting these variables is by setting them in /etc/ mk.conf. A complete list of the variables that can be configured by the user is available in mk/defaults/mk.conf, together with some comments that describe the variable's intent. * LOCALBASE: Where packages will be installed. The default is /usr/pkg. Do not mix binary packages with different LOCALBASEs! * CROSSBASE: Where "cross" category packages will be installed. The default is ${LOCALBASE}/cross. * X11BASE: Where X11 is installed on the system. The default is /usr/X11R6. * DISTDIR: Where to store the downloaded copies of the original source distributions used for building pkgsrc packages. The default is $ {PKGSRCDIR}/distfiles. * MASTER_SITE_OVERRIDE: If set, override the packages' MASTER_SITES with this value. * MASTER_SITE_BACKUP: Backup location(s) for distribution files and patch files if not found locally or in ${MASTER_SITES} or ${PATCH_SITES} respectively. The defaults are ftp://ftp.NetBSD.org/pub/NetBSD/packages/ distfiles/${DIST_SUBDIR}/ and ftp://ftp.freebsd.org/pub/FreeBSD/distfiles/$ {DIST_SUBDIR}/. * BINPKG_SITES: List of sites carrying binary pkgs. * ACCEPTABLE_LICENSES: List of acceptable licenses. Whenever you try to build a package whose license is not in this list, you will get an error message that includes instructions on how to change this variable. 5.2. Variables affecting the build process XXX * PACKAGES: The top level directory for the binary packages. The default is $ {PKGSRCDIR}/packages. * WRKOBJDIR: The top level directory where, if defined, the separate working directories will get created, and symbolically linked to from ${WRKDIR} (see below). This is useful for building packages on several architectures, then ${PKGSRCDIR} can be NFS-mounted while ${WRKOBJDIR} is local to every architecture. (It should be noted that PKGSRCDIR should not be set by the user ? it is an internal definition which refers to the root of the pkgsrc tree. It is possible to have many pkgsrc tree instances.) * LOCALPATCHES: Directory for local patches that aren't part of pkgsrc. See Section 9.3, "patches/*" for more information. rel and arch are replaced with OS release ("2.0", etc.) and architecture ("mipsel", etc.). * PKGMAKECONF: Location of the mk.conf file used by a package's BSD-style Makefile. If this is not set, MAKECONF is set to /dev/null to avoid picking up settings used by builds in /usr/src. * DEPENDS_TARGET: By default, dependencies are only installed, and no binary package is created for them. You can set this variable to package to automatically create binary packages after installing dependencies. 5.3. Selecting and configuring the compiler 5.3.1. Additional flags to the compiler (CFLAGS) If you wish to set the CFLAGS variable, please make sure to use the += operator instead of the = operator: CFLAGS+= -your -flags Using CFLAGS= (i.e. without the "+") may lead to problems with packages that need to add their own flags. Also, you may want to take a look at the devel/ cpuflags package if you're interested in optimization for the current CPU. 5.4. Developer/advanced settings XXX * PKG_DEVELOPER: Run some sanity checks that package developers want: o make sure patches apply with zero fuzz o run check-shlibs to see that all binaries will find their shared libs. * PKG_DEBUG_LEVEL: The level of debugging output which is displayed whilst making and installing the package. The default value for this is 0, which will not display the commands as they are executed (normal, default, quiet operation); the value 1 will display all shell commands before their invocation, and the value 2 will display both the shell commands before their invocation, and their actual execution progress with set -x will be displayed. 5.5. Selecting Build Options Some packages have build time options, usually to select between different dependencies, enable optional support for big dependencies or enable experimental features. To see which options, if any, a package supports, and which options are mutually exclusive, run make show-options, for example: The following options are supported by this package: ssl Enable SSL support. Exactly one of the following gecko options is required: firefox Use firefox as gecko rendering engine. mozilla Use mozilla as gecko rendering engine. At most one of the following database options may be selected: mysql Enable support for MySQL database. pgsql Enable support for PostgreSQL database. These options are enabled by default: firefox These options are currently enabled: mozilla ssl The following variables can be defined in /etc/mk.conf to select which options to enable for a package: PKG_DEFAULT_OPTIONS, which can be used to select or disable options for all packages that support them, and PKG_OPTIONS.pkgbase, which can be used to select or disable options specifically for package pkgbase . Options listed in these variables are selected, options preceded by "-" are disabled. A few examples: $ grep "PKG.*OPTION" /etc/mk.conf PKG_DEFAULT_OPTIONS= -arts -dvdread -esound PKG_OPTIONS.kdebase= debug -sasl PKG_OPTIONS.apache= suexec The following settings are consulted in the order given, and the last setting that selects or disables an option is used: 1. the default options as suggested by the package maintainer 2. the options implied by the settings of legacy variables (see below) 3. PKG_DEFAULT_OPTIONS 4. PKG_OPTIONS.pkgbase For groups of mutually exclusive options, the last option selected is used, all others are automatically disabled. If an option of the group is explicitly disabled, the previously selected option, if any, is used. It is an error if no option from a required group of options is selected, and building the package will fail. Before the options framework was introduced, build options were selected by setting a variable (often named USE_FOO) in /etc/mk.conf for each option. To ease transition to the options framework for the user, these legacy variables are converted to the appropriate options setting (PKG_OPTIONS.pkgbase) automatically. A warning is issued to prompt the user to update /etc/mk.conf to use the options framework directly. Support for the legacy variables will be removed eventually. Chapter 6.

Uploading results of a bulk build 6.4. Creating a multiple CD-ROM packages collection 6.4.1. Example of cdpack 6.1. Building a single binary package Once you have built and installed a package, you can create a binary package which can be installed on another system with pkg_add(1). This saves having to build the same package on a group of hosts and wasting CPU time. It also provides a simple means for others to install your package, should you distribute it. To create a binary package, change into the appropriate directory in pkgsrc, and run make package: # cd misc/figlet # make package This will build and install your package (if not already done), and then build a binary package from what was installed. You can then use the pkg_* tools to manipulate it. Binary packages are created by default in /usr/pkgsrc/packages, in the form of a gzipped tar file. See Section B.2, "Packaging figlet" for a continuation of the above misc/figlet example. See Chapter 19, Submitting and Committing for information on how to submit such a binary package. 6.2. Settings for creation of binary packages See Section 15.16, "Other helpful targets". 6.3. Doing a bulk build of all packages If you want to get a full set of precompiled binary packages, this section describes how to get them. Beware that the bulk build will remove all currently installed packages from your system! Having an FTP server configured either on the machine doing the bulk builds or on a nearby NFS server can help to make the packages available to other machines that can then save time by installing only the binary packages. See ftpd(8) for more information. If you use a remote NFS server's storage, be sure to not actually compile on NFS storage, as this slows things down a lot. 6.3.1. Configuration 6.3.1.1. build.conf The build.conf file is the main configuration file for bulk builds. You can configure how your copy of pkgsrc is kept up to date, how the distfiles are downloaded, how the packages are built and how the report is generated. You can find an annotated example file in pkgsrc/mk/bulk/build.conf-example. To use it, copy build.conf-example to build.conf and edit it, following the comments in that file. 6.3.1.2. /etc/mk.conf You may want to set variables in /etc/mk.conf. Look at pkgsrc/mk/defaults/ mk.conf for details of the default settings. You will want to ensure that ACCEPTABLE_LICENSES meet your local policy. As used in this example, _ACCEPTABLE=yes accepts all licenses. PACKAGES?= ${_PKGSRCDIR}/packages/${MACHINE_ARCH} WRKOBJDIR?= /usr/tmp/pkgsrc # build here instead of in pkgsrc BSDSRCDIR= /usr/src BSDXSRCDIR= /usr/xsrc # for x11/xservers OBJHOSTNAME?= yes # use work.`hostname` FAILOVER_FETCH= yes # insist on the correct checksum PKG_DEVELOPER?= yes _ACCEPTABLE= yes Some options that are especially useful for bulk builds can be found at the top lines of the file mk/bulk/bsd.bulk-pkg.mk. The most useful options of these are briefly described here. * If you are on a slow machine, you may want to set USE_BULK_BROKEN_CHECK to "no". * If you are doing bulk builds from a read-only copy of pkgsrc, you have to set BULKFILESDIR to the directory where all log files are created. Otherwise the log files are created in the pkgsrc directory. * Another important variable is BULK_PREREQ, which is a list of packages that should be always available while building other packages. Some other options are scattered in the pkgsrc infrastructure: * ALLOW_VULNERABLE_PACKAGES should be set to yes. The purpose of the bulk builds is creating binary packages, no matter if they are vulnerable or not. When uploading the packages to a public server, the vulnerable packages will be put into a directory of their own. Leaving this variable unset would prevent the bulk build system from even trying to build them, so possible building errors would not show up. * CHECK_FILES (pkgsrc/mk/bsd.pkg.check.mk) can be set to "yes" to check that the installed set of files matches the PLIST. * CHECK_INTERPRETER (pkgsrc/mk/bsd.pkg.check.mk) can be set to "yes" to check that the installed "#!"-scripts will find their interpreter. 6.3.1.3. pre-build.local It is possible to configure the bulk build to perform certain site-specific tasks at the end of the pre-build stage. If the file pre-build.local exists in /usr/pkgsrc/mk/bulk, it will be executed (as a sh(1) script) at the end of the usual pre-build stage. An example use of pre-build.local is to have the line: echo "I do not have enough disk space to build this pig." \ > misc/openoffice/$BROKENF to prevent the system from trying to build a particular package which requires nearly 3 GB of disk space. 6.3.2. Other environmental considerations As /usr/pkg will be completely deleted at the start of bulk builds, make sure your login shell is placed somewhere else. Either drop it into /usr/local/bin (and adjust your login shell in the passwd file), or (re-)install it via pkg_add(1) from /etc/rc.local, so you can login after a reboot (remember that your current process won't die if the package is removed, you just can't start any new instances of the shell any more). Also, if you use NetBSD earlier than 1.5, or you still want to use the pkgsrc version of ssh for some reason, be sure to install ssh before starting it from rc.local: ( cd /usr/pkgsrc/security/ssh ; make bulk-install ) if [ -f /usr/pkg/etc/rc.d/sshd ]; then /usr/pkg/etc/rc.d/sshd fi Not doing so will result in you being not able to log in via ssh after the bulk build is finished or if the machine gets rebooted or crashes. You have been warned! :) 6.3.3. Operation Make sure you don't need any of the packages still installed. Warning During the bulk build, all packages will be removed! Be sure to remove all other things that might interfere with builds, like some libs installed in /usr/local, etc. then become root and type: # cd /usr/pkgsrc # sh mk/bulk/build If for some reason your last build didn't complete (power failure, system panic, ...), you can continue it by running: # sh mk/bulk/build restart At the end of the bulk build, you will get a summary via mail, and find build logs in the directory specified by FTP in the build.conf file. 6.3.4. What it does The bulk builds consist of three steps: 1. pre-build The script updates your pkgsrc tree via (anon)cvs, then cleans out any broken distfiles, and removes all packages installed. 2. the bulk build This is basically "make bulk-package" with an optimised order in which packages will be built. Packages that don't require other packages will be built first, and packages with many dependencies will be built later. 3. post-build Generates a report that's placed in the directory specified in the build.conf file named broken.html, a short version of that report will also be mailed to the build's admin. During the build, a list of broken packages will be compiled in /usr/pkgsrc /.broken (or .../.broken.${MACHINE} if OBJMACHINE is set), individual build logs of broken builds can be found in the package's directory. These files are used by the bulk-targets to mark broken builds to not waste time trying to rebuild them, and they can be used to debug these broken package builds later. 6.3.5. Disk space requirements Currently, roughly the following requirements are valid for NetBSD 2.0/i386: * 10 GB - distfiles (NFS ok) * 8 GB - full set of all binaries (NFS ok) * 5 GB - temp space for compiling (local disk recommended) Note that all pkgs will be de-installed as soon as they are turned into a binary package, and that sources are removed, so there is no excessively huge demand to disk space. Afterwards, if the package is needed again, it will be installed via pkg_add(1) instead of building again, so there are no cycles wasted by recompiling. 6.3.6. Setting up a sandbox for chrooted builds If you don't want all the packages nuked from a machine (rendering it useless for anything but pkg compiling), there is the possibility of doing the package bulk build inside a chroot environment. The first step is to set up a chroot sandbox, e.g. /usr/sandbox. This can be done by using null mounts, or manually. There is a shell script called pkgsrc/mk/bulk/mksandbox which will set up the sandbox environment using null mounts. It will also create a script called sandbox in the root of the sandbox environment, which will allow the null mounts to be activated using the sandbox mount command and deactivated using the sandbox umount command. To set up a sandbox environment by hand, after extracting all the sets from a NetBSD installation or doing a make distribution DESTDIR=/usr/sandbox in /usr/ src/etc, be sure the following items are present and properly configured: 1. Kernel # cp /netbsd /usr/sandbox 2. /dev/* # cd /usr/sandbox/dev ; sh MAKEDEV all 3. /etc/resolv.conf (for security/smtpd and mail): # cp /etc/resolv.conf /usr/sandbox/etc 4. Working(!) mail config (hostname, sendmail.cf): # cp /etc/mail/sendmail.cf /usr/sandbox/etc/mail 5. /etc/localtime (for security/smtpd): # ln -sf /usr/share/zoneinfo/UTC /usr/sandbox/etc/localtime 6. /usr/src (system sources, e. g. for sysutils/aperture): # ln -s ../disk1/cvs . # ln -s cvs/src-2.0 src 7. Create /var/db/pkg (not part of default install): # mkdir /usr/sandbox/var/db/pkg 8. Create /usr/pkg (not part of default install): # mkdir /usr/sandbox/usr/pkg 9. Checkout pkgsrc via cvs into /usr/sandbox/usr/pkgsrc: # cd /usr/sandbox/usr # cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -d -P pkgsrc Do not mount/link this to the copy of your pkgsrc tree you do development in, as this will likely cause problems! 10. Make /usr/sandbox/usr/pkgsrc/packages and .../distfiles point somewhere appropriate. NFS- and/or nullfs-mounts may come in handy! 11. Edit /etc/mk.conf, see Section 6.3.1.2, "/etc/mk.conf". 12. Adjust mk/bulk/build.conf to suit your needs. When the chroot sandbox is set up, you can start the build with the following steps: # cd /usr/sandbox/usr/pkgsrc # sh mk/bulk/do-sandbox-build This will just jump inside the sandbox and start building. At the end of the build, mail will be sent with the results of the build. Created binary pkgs will be in /usr/sandbox/usr/pkgsrc/packages (wherever that points/mounts to/ from). 6.3.7. Building a partial set of packages In addition to building a complete set of all packages in pkgsrc, the pkgsrc/mk /bulk/build script may be used to build a subset of the packages contained in pkgsrc. By setting SPECIFIC_PKGS in /etc/mk.conf, the variables * SITE_SPECIFIC_PKGS * HOST_SPECIFIC_PKGS * GROUP_SPECIFIC_PKGS * USER_SPECIFIC_PKGS will define the set of packages which should be built. The bulk build code will also include any packages which are needed as dependencies for the explicitly listed packages. One use of this is to do a bulk build with SPECIFIC_PKGS in a chroot sandbox periodically to have a complete set of the binary packages needed for your site available without the overhead of building extra packages that are not needed. 6.3.8. Uploading results of a bulk build This section describes how pkgsrc developers can upload binary pkgs built by bulk builds to ftp.NetBSD.org. If you would like to automatically create checksum files for the binary packages you intend to upload, remember to set MKSUMS=yes in your mk/bulk/ build.conf. If you would like to PGP sign the checksum files (highly recommended!), remember to set SIGN_AS=username@NetBSD.org in your mk/bulk/build.conf. This will prompt you for your GPG password to sign the files before uploading everything. Then, make sure that you have RSYNC_DST set properly in your mk/bulk/build.conf file, i.e. adjust it to something like one of the following: RSYNC_DST=ftp.NetBSD.org:/pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload Please use appropriate values for "pkgsrc-200xQy", "NetBSD-a.b.c" and "arch" here. If your login on ftp.NetBSD.org is different from your local login, write your login directly into the variable, e.g. my local account is "feyrer", but for my login "hubertf", I use: RSYNC_DST=hubertf@ftp.NetBSD.org:/pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload A separate upload directory is used here to allow "closing" the directory during upload. To do so, run the following command on ftp.NetBSD.org next: nbftp% mkdir -p -m 750 /pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch/upload Please note that /pub/NetBSD/packages is only appropriate for packages for the NetBSD operating system. Binary packages for other operating systems should go into /pub/pkgsrc. Before uploading the binary pkgs, ssh authentication needs to be set up. This example shows how to set up temporary keys for the root account inside the sandbox (assuming that no keys should be present there usually): # chroot /usr/sandbox chroot-# rm $HOME/.ssh/id-dsa* chroot-# ssh-keygen -t dsa chroot-# cat $HOME/.ssh/id-dsa.pub Now take the output of id-dsa.pub and append it to your ~/.ssh/authorized_keys file on ftp.NetBSD.org. You can remove the key after the upload is done! Next, test if your ssh connection really works: chroot-# ssh ftp.NetBSD.org date Use "-l yourNetBSDlogin" here as appropriate! Now after all this works, you can exit the sandbox and start the upload: chroot-# exit # cd /usr/sandbox/usr/pkgsrc # sh mk/bulk/do-sandbox-upload The upload process may take quite some time. Use ls(1) or du(1) on the FTP server to monitor progress of the upload. The upload script will take care of not uploading restricted packages and putting vulnerable packages into the vulnerable subdirectory. After the upload has ended, first thing is to revoke ssh access: nbftp% vi ~/.ssh/authorized_keys Gdd:x! Use whatever is needed to remove the key you've entered before! Last, move the uploaded packages out of the upload directory to have them accessible to everyone: nbftp% cd /pub/NetBSD/packages/pkgsrc-200xQy/NetBSD-a.b.c/arch nbftp% mv upload/* . nbftp% rmdir upload nbftp% chmod 755 . 6.4. Creating a multiple CD-ROM packages collection After your pkgsrc bulk-build has completed, you may wish to create a CD-ROM set of the resulting binary packages to assist in installing packages on other machines. The pkgtools/cdpack package provides a simple tool for creating the ISO 9660 images. cdpack arranges the packages on the CD-ROMs in a way that keeps all the dependencies for a given package on the same CD as that package. 6.4.1. Example of cdpack Complete documentation for cdpack is found in the cdpack(1) man page. The following short example assumes that the binary packages are left in /usr/ pkgsrc/packages/All and that sufficient disk space exists in /u2 to hold the ISO 9660 images. # mkdir /u2/images # pkg_add /usr/pkgsrc/packages/All/cdpack # cdpack /usr/pkgsrc/packages/All /u2/images If you wish to include a common set of files (COPYRIGHT, README, etc.) on each CD in the collection, then you need to create a directory which contains these files. e.g. # mkdir /tmp/common # echo "This is a README" > /tmp/common/README # echo "Another file" > /tmp/common/COPYING # mkdir /tmp/common/bin # echo "#!/bin/sh" > /tmp/common/bin/myscript # echo "echo Hello world" >> /tmp/common/bin/myscript # chmod 755 /tmp/common/bin/myscript Now create the images: # cdpack -x /tmp/common /usr/pkgsrc/packages/All /u2/images Each image will contain README, COPYING, and bin/myscript in their root directories.

This section contains hints, tips & tricks on special things in pkgsrc that we didn't find a better place for in the previous chapters, and it contains items for both pkgsrc users and developers. 7.1. Are there any mailing lists for pkg-related discussion? The following mailing lists may be of interest to pkgsrc users: * pkgsrc-users: This is a general purpose list for most issues regarding pkgsrc, regardless of platform, e.g. soliciting user help for pkgsrc configuration, unexpected build failures, using particular packages, upgrading pkgsrc installations, questions regarding the pkgsrc release branches, etc. General announcements or proposals for changes that impact the pkgsrc user community, e.g. major infrastructure changes, new features, package removals, etc., may also be posted. * pkgsrc-bulk: A list where the results of pkgsrc bulk builds are sent and discussed. * pkgsrc-changes: This list is for those who are interested in getting a commit message for every change committed to pkgsrc. It is also available in digest form, meaning one daily message containing all commit messages for changes to the package source tree in that 24 hour period. To subscribe, do: % echo subscribe listname | mail majordomo@NetBSD.org Archives for all these mailing lists are available from http:// mail-index.NetBSD.org/. 7.2. Where's the pkgviews documentation? Pkgviews is tightly integrated with buildlink. You can find a pkgviews User's guide in pkgsrc/mk/buildlink3/PKGVIEWS_UG. 7.3. Utilities for package management (pkgtools) The directory pkgsrc/pkgtools contains a number of useful utilities for both users and developers of pkgsrc. This section attempts only to make the reader aware of the utilities and when they might be useful, and not to duplicate the documentation that comes with each package. Utilities used by pkgsrc (automatically installed when needed): * pkgtools/x11-links: Symlinks for use by buildlink. OS tool augmentation (automatically installed when needed): * pkgtools/digest: Calculates various kinds of checksums (including SHA1). * pkgtools/libnbcompat: Compatibility library for pkgsrc tools. * pkgtools/mtree: Installed on non-BSD systems due to lack of native mtree. * pkgtools/pkg_install: Up-to-date replacement for /usr/sbin/pkg_install, or for use on operating systems where pkg_install is not present. Utilities used by pkgsrc (not automatically installed): * pkgtools/pkg_tarup: Create a binary package from an already-installed package. Used by make replace to save the old package. * pkgtools/dfdisk: Adds extra functionality to pkgsrc, allowing it to fetch distfiles from multiple locations. It currently supports the following methods: multiple CD-ROMs and network FTP/HTTP connections. * pkgtools/xpkgwedge: Put X11 packages someplace else (enabled by default). * devel/cpuflags: Determine the best compiler flags to optimise code for your current CPU and compiler. Utilities for keeping track of installed packages, being up to date, etc: * pkgtools/pkg_chk: Reports on packages whose installed versions do not match the latest pkgsrc entries. * pkgtools/pkgdep: Makes dependency graphs of packages, to aid in choosing a strategy for updating. * pkgtools/pkgdepgraph: Makes graphs from the output of pkgtools/pkgdep (uses graphviz). * pkgtools/pkglint: The pkglint(1) program checks a pkgsrc entry for errors, lintpkgsrc(1) does various checks on the complete pkgsrc system. * pkgtools/pkgsurvey: Report what packages you have installed. Utilities for people maintaining or creating individual packages: * pkgtools/pkgdiff: Automate making and maintaining patches for a package (includes pkgdiff, pkgvi, mkpatches, etc.). * pkgtools/rpm2pkg, pkgtools/url2pkg: Aids in converting to pkgsrc. * pkgtools/gensolpkg: Convert pkgsrc to a Solaris package. Utilities for people maintaining pkgsrc (or: more obscure pkg utilities) * pkgtools/pkg_comp: Build packages in a chrooted area. * pkgtools/libkver: Spoof kernel version for chrooted cross builds. 7.4. How to use pkgsrc as non-root If you want to use pkgsrc as non-root user, you can set some variables to make pkgsrc work under these conditions. At the very least, you need to set UNPRIVILEGED to "yes"; this will turn on unprivileged mode and set multiple related variables to allow installation of packages as non-root. In case the defaults are not enough, you may want to tune some other variables used. For example, if the automatic user/group detection leads to incorrect values (or not the ones you would like to use), you can change them by setting UNPRIVILEGED_USER and UNPRIVILEGED_GROUP respectively. As regards bootstrapping, please note that the bootstrap script will ease non-root configuration when given the "--ignore-user-check" flag, as it will choose and use multiple default directories under ~/pkg as the installation targets. These directories can be overriden by the "--prefix" flag provided by the script, as well as some others that allow finer tuning of the tree layout. 7.5. How to resume transfers when fetching distfiles? By default, resuming transfers in pkgsrc is disabled, but you can enable this feature by adding the option PKG_RESUME_TRANSFERS=YES into /etc/mk.conf. If, during a fetch step, an incomplete distfile is found, pkgsrc will try to resume it. You can also use a different program than the default ftp(1) by changing the FETCH_CMD variable. Don't forget to set FETCH_RESUME_ARGS and FETCH_OUTPUT_ARGS if you are not using default values. For example, if you want to use wget to resume downloads, you'll have to use something like: FETCH_CMD= wget FETCH_BEFORE_ARGS= --passive-ftp FETCH_RESUME_ARGS= -c FETCH_OUTPUT_ARGS= -O 7.6. How can I install/use XFree86 from pkgsrc? If you want to use XFree86 from pkgsrc instead of your system's own X11 (/usr/ X11R6, /usr/openwin, ...), you will have to add the following line into /etc/ mk.conf: X11_TYPE=XFree86 7.7. How can I install/use X.org from pkgsrc? If you want to use X.org from pkgsrc instead of your system's own X11 (/usr/ X11R6, /usr/openwin, ...) you will have to add the following line into /etc/ mk.conf: X11_TYPE=xorg Note The DragonFly operating system defaults to using this X.org X11 implementation from pkgsrc. 7.8. How to fetch files from behind a firewall If you are sitting behind a firewall which does not allow direct connections to Internet hosts (i.e. non-NAT), you may specify the relevant proxy hosts. This is done using an environment variable in the form of a URL, e.g. in Amdahl, the machine "orpheus.amdahl.com" is one of the firewalls, and it uses port 80 as the proxy port number. So the proxy environment variables are: ftp_proxy=ftp://orpheus.amdahl.com:80/ http_proxy=http://orpheus.amdahl.com:80/ 7.9. How do I tell make fetch to do passive FTP? This depends on which utility is used to retrieve distfiles. From bsd.pkg.mk, FETCH_CMD is assigned the first available command from the following list: * ${LOCALBASE}/bin/ftp * /usr/bin/ftp On a default NetBSD installation, this will be /usr/bin/ftp, which automatically tries passive connections first, and falls back to active connections if the server refuses to do passive. For the other tools, add the following to your /etc/mk.conf file: PASSIVE_FETCH=1. Having that option present will prevent /usr/bin/ftp from falling back to active transfers. 7.10. How to fetch all distfiles at once You would like to download all the distfiles in a single batch from work or university, where you can't run a make fetch. There is an archive of distfiles on ftp.NetBSD.org, but downloading the entire directory may not be appropriate. The answer here is to do a make fetch-list in /usr/pkgsrc or one of its subdirectories, carry the resulting list to your machine at work/school and use it there. If you don't have a NetBSD-compatible ftp(1) (like tnftp) at work, don't forget to set FETCH_CMD to something that fetches a URL: At home: % cd /usr/pkgsrc % make fetch-list FETCH_CMD=wget DISTDIR=/tmp/distfiles >/tmp/fetch.sh % scp /tmp/fetch.sh work:/tmp At work: % sh /tmp/fetch.sh then tar up /tmp/distfiles and take it home. If you have a machine running NetBSD, and you want to get all distfiles (even ones that aren't for your machine architecture), you can do so by using the above-mentioned make fetch-list approach, or fetch the distfiles directly by running: % make mirror-distfiles If you even decide to ignore NO_{SRC,BIN}_ON_{FTP,CDROM}, then you can get everything by running: % make fetch NO_SKIP=yes 7.11. What does "Don't know how to make /usr/share/tmac/tmac.andoc" mean? When compiling the pkgtools/pkg_install package, you get the error from make that it doesn't know how to make /usr/share/tmac/tmac.andoc? This indicates that you don't have installed the "text" set (nroff, ...) from the NetBSD base distribution on your machine. It is recommended to do that to format man pages. In the case of the pkgtools/pkg_install package, you can get away with setting NOMAN=YES either in the environment or in /etc/mk.conf. 7.12. What does "Could not find bsd.own.mk" mean? You didn't install the compiler set, comp.tgz, when you installed your NetBSD machine. Please get and install it, by extracting it in /: # cd / # tar --unlink -zxvpf .../comp.tgz comp.tgz is part of every NetBSD release. Get the one that corresponds to your release (determine via uname -r). 7.13. Using 'sudo' with pkgsrc When installing packages as non-root user and using the just-in-time su(1) feature of pkgsrc, it can become annoying to type in the root password for each required package installed. To avoid this, the sudo package can be used, which does password caching over a limited time. To use it, install sudo (either as binary package or from security/sudo) and then put the following into your /etc /mk.conf: .if exists(${LOCALBASE}/bin/sudo) SU_CMD= ${LOCALBASE}/bin/sudo /bin/sh -c .endif 7.14. How do I change the location of configuration files? As the system administrator, you can choose where configuration files are installed. The default settings make all these files go into ${PREFIX}/etc or some of its subdirectories; this may be suboptimal depending on your expectations (e.g., a read-only, NFS-exported PREFIX with a need of per-machine configuration of the provided packages). In order to change the defaults, you can modify the PKG_SYSCONFBASE variable (in /etc/mk.conf) to point to your preferred configuration directory; some common examples include /etc or /etc/pkg. Furthermore, you can change this value on a per-package basis by setting the PKG_SYSCONFDIR.${PKG_SYSCONFVAR} variable. PKG_SYSCONFVAR's value usually matches the name of the package you would like to modify, that is, the contents of PKGBASE. Note that after changing these settings, you must rebuild and reinstall any affected packages. 7.15. Automated security checks Please be aware that there can often be bugs in third-party software, and some of these bugs can leave a machine vulnerable to exploitation by attackers. In an effort to lessen the exposure, the NetBSD packages team maintains a database of known-exploits to packages which have at one time been included in pkgsrc. The database can be downloaded automatically, and a security audit of all packages installed on a system can take place. To do this, install the security /audit-packages package. It has two components: 1. download-vulnerability-list, an easy way to download a list of the security vulnerabilities information. This list is kept up to date by the NetBSD security officer and the NetBSD packages team, and is distributed from the NetBSD ftp server: ftp://ftp.NetBSD.org/pub/NetBSD/packages/distfiles/pkg-vulnerabilities 2. audit-packages, an easy way to audit the current machine, checking each vulnerability which is known. If a vulnerable package is installed, it will be shown by output to stdout, including a description of the type of vulnerability, and a URL containing more information. Use of the security/audit-packages package is strongly recommended! After "audit-packages" is installed, please read the package's message, which you can get by running pkg_info -D audit-packages. If this package is installed, pkgsrc builds will use it to perform a security check before building any package. See Section 5.2, "Variables affecting the build process" for ways to control this check. 7.16. Why do some packages ignore my CFLAGS? When you add your own preferences to the CFLAGS variable in your mk.conf, these flags are passed in environment variables to the ./configure scripts and to make(1). Some package authors ignore the CFLAGS from the environment variable by overriding them in the Makefiles of their package. Currently there is no solution to this problem. If you really need the package to use your CFLAGS you should run make patch in the package directory and then inspect any Makefile and Makefile.in for whether they define CFLAGS explicitly. Usually you can remove these lines. But be aware that some "smart" programmers write so bad code that it only works for the specific combination of CFLAGS they have chosen. 7.17. A package does not build. What shall I do? 1. Make sure that your copy of pkgsrc is consistent. A case that occurs often is that people only update pkgsrc in parts, because of performance reasons. Since pkgsrc is one large system, not a collection of many small systems, there are sometimes changes that only work when the whole pkgsrc tree is updated. 2. Make sure that you don't have any CVS conflicts. Search for "<<<<<<" or ">>>>>>" in all your pkgsrc files. 3. Make sure that you don't have old copies of the packages extracted. Run make clean clean-depends to verify this. 4. If the problem still exists, write a mail to the pkgsrc-users mailing list. Part II.

Creating a new pkgsrc package from scratch When you find a package that is not yet in pkgsrc, you most likely have a URL from where you can download the source code. Starting with this URL, creating a package involves only a few steps. 1. First, install the packages pkgtools/url2pkg and pkgtools/pkglint. 2. Then, choose one of the top-level directories as the category in which you want to place your package. You can also create a directory of your own (maybe called local). In that category directory, create another directory for your package and change into it. 3. Run the program url2pkg, which will ask you for a URL. Enter the URL of the distribution file (in most cases a .tar.gz file) and watch how the basic ingredients of your package are created automatically. The distribution file is extracted automatically to fill in some details in the Makefile that would otherwise have to be done manually. 4. Examine the extracted files to determine the dependencies of your package. Ideally, this is mentioned in some README file, but things may differ. For each of these dependencies, look where it exists in pkgsrc, and if there is a file called buildlink3.mk in that directory, add a line to your package Makefile which includes that file just before the last line. If the buildlink3.mk file does not exist, add a DEPENDS line to the Makefile, which specifies the version of the dependency and where it can be found in pkgsrc. This line should be placed in the third paragraph. If the dependency is only needed for building the package, but not when using it, use BUILD_DEPENDS instead of DEPENDS. Your package may then look like this: [...] BUILD_DEPENDS+= lua>=5.0:../../lang/lua DEPENDS+= screen-[0-9]*:../../misc/screen DEPENDS+= screen>=4.0:../../misc/screen [...] .include "../../category/package/buildlink3.mk" .include "../../devel/glib2/buildlink3.mk" .include "../../mk/bsd.pkg.mk" 5. Run pkglint to see what things still need to be done to make your package a "good" one. If you don't know what pkglint's warnings want to tell you, try pkglint --explain or pkglint -e, which outputs additional explanations. 6. Now, run bmake to build the package. For the various things that can go wrong in this phase, consult Chapter 17, Making your package work. 7. When the package builds fine, the next step is to install the package. Run bmake install and hope that everything works. 8. Up to now, the file PLIST, which contains a list of the files that are installed by the package, is nearly empty. Run bmake print-PLIST >PLIST to generate a probably correct list. Check the file using your preferred text editor to see if the list of files looks plausible. 9. Run pkglint again to see if the generated PLIST contains garbage or not. 10. When you ran bmake install, the package has been registered in the database of installed files, but with an empty list of files. To fix this, run bmake deinstall and bmake install again. Now the package is registered with the list of files from PLIST. 11. Run bmake package to create a binary package from the set of installed files. Chapter 9.

Files affecting the binary package 9.5.2. Files affecting the build process 9.5.3. Files affecting nothing at all 9.6. work* 9.7. files/* Whenever you're preparing a package, there are a number of files involved which are described in the following sections. 9.1. Makefile Building, installation and creation of a binary package are all controlled by the package's Makefile. The Makefile describes various things about a package, for example from where to get it, how to configure, build, and install it. A package Makefile contains several sections that describe the package. In the first section there are the following variables, which should appear exactly in the order given here. The ordering and grouping of variables is mostly historical and has no further meaning. * DISTNAME is the basename of the distribution file to be downloaded from the package's website. * PKGNAME is the name of the package, as used by pkgsrc. You only need to provide it if it differs from DISTNAME. Usually it is the directory name together with the version number. It must match the regular expression ^ [A-Za-z0-9][A-Za-z0-9-_.+]*$, that is, it starts with a letter or digit, and contains only letters, digits, dashes, underscores, dots and plus signs. * CATEGORIES is a list of categories which the package fits in. You can choose any of the top-level directories of pkgsrc for it. Currently the following values are available for CATEGORIES. If more than one is used, they need to be separated by spaces: archivers cross geography meta-pkgs security audio databases graphics misc shells benchmarks devel ham multimedia sysutils biology editors inputmethod net textproc cad emulators lang news time chat finance mail parallel wm comms fonts math pkgtools www converters games mbone print x11 * MASTER_SITES, DYNAMIC_MASTER_SITES, DIST_SUBDIR, EXTRACT_SUFX and DISTFILES are discussed in detail in Section 15.5, "The fetch phase". The second section contains information about separately downloaded patches, if any. * PATCHFILES: Name(s) of additional files that contain distribution patches. There is no default. pkgsrc will look for them at PATCH_SITES. They will automatically be uncompressed before patching if the names end with .gz or .Z. * PATCH_SITES: Primary location(s) for distribution patch files (see PATCHFILES below) if not found locally. The third section contains the following variables. * MAINTAINER is the email address of the person who feels responsible for this package, and who is most likely to look at problems or questions regarding this package which have been reported with send-pr(1). Other developers should contact the MAINTAINER before making major changes to the package. When packaging a new program, set MAINTAINER to yourself. If you really can't maintain the package for future updates, set it to < pkgsrc-users@NetBSD.org>. * HOMEPAGE is a URL where users can find more information about the package. * COMMENT is a one-line description of the package (should not include the package name). Other variables that affect the build: * WRKSRC: The directory where the interesting distribution files of the package are found. The default is ${WRKDIR}/${DISTNAME}, which works for most packages. If a package doesn't create a subdirectory for itself (most GNU software does, for instance), but extracts itself in the current directory, you should set WRKSRC= ${WRKDIR}. If a package doesn't create a subdirectory with the name of DISTNAME but some different name, set WRKSRC to point to the proper name in ${WRKDIR}, for example WRKSRC= ${WRKDIR}/${DISTNAME}/unix. See lang/tcl and x11/tk for other examples. The name of the working directory created by pkgsrc is taken from the WRKDIR_BASENAME variable. By default, its value is work. If you want to use the same pkgsrc tree for building different kinds of binary packages, you can change the variable according to your needs. Two other variables handle common cases of setting WRKDIR_BASENAME individually. If OBJHOSTNAME is defined in /etc/mk.conf, the first component of the host's name is attached to the directory name. If OBJMACHINE is defined, the platform name is attached, which might look like work.i386 or work.sparc. Please pay attention to the following gotchas: * Add MANCOMPRESSED if man pages are installed in compressed form by the package; see comment in bsd.pkg.mk. * Replace /usr/local with "${PREFIX}" in all files (see patches, below). * If the package installs any info files, see Section 17.5.7, "Packages installing info files". 9.2. distinfo The distinfo file contains the message digest, or checksum, of each distfile needed for the package. This ensures that the distfiles retrieved from the Internet have not been corrupted during transfer or altered by a malign force to introduce a security hole. Due to recent rumor about weaknesses of digest algorithms, all distfiles are protected using both SHA1 and RMD160 message digests, as well as the file size. The distinfo file also contains the checksums for all the patches found in the patches directory (see Section 9.3, "patches/*"). To regenerate the distinfo file, use the make makedistinfo or make mdi command. Some packages have different sets of distfiles depending on the platform, for example www/navigator). These are kept in the same distinfo file and care should be taken when upgrading such a package to ensure distfile information is not lost. 9.3. patches/* This directory contains files that are used by the patch(1) command to modify the sources as distributed in the distribution file into a form that will compile and run perfectly on NetBSD. The files are applied successively in alphabetic order (as returned by a shell "patches/patch-*" glob expansion), so patch-aa is applied before patch-ab, etc. The patch-* files should be in diff -bu format, and apply without a fuzz to avoid problems. (To force patches to apply with fuzz you can set PATCH_FUZZ_FACTOR=-F2). Furthermore, do not put changes for more than one file into a single patch file, as this will make future modifications more difficult. Similar, a file should be patched at most once, not several times by several different patches. If a file needs several patches, they should be combined into one file. One important thing to mention is to pay attention that no RCS IDs get stored in the patch files, as these will cause problems when later checked into the NetBSD CVS tree. Use the pkgdiff from the pkgtools/pkgdiff package to avoid these problems. For even more automation, we recommend using mkpatches from the same package to make a whole set of patches. You just have to backup files before you edit them to filename.orig, e.g. with cp -p filename filename.orig or, easier, by using pkgvi again from the same package. If you upgrade a package this way, you can easily compare the new set of patches with the previously existing one with patchdiff. When you have finished a package, remember to generate the checksums for the patch files by using the make makepatchsum command, see Section 9.2, "distinfo" . When adding a patch that corrects a problem in the distfile (rather than e.g. enforcing pkgsrc's view of where man pages should go), send the patch as a bug report to the maintainer. This benefits non-pkgsrc users of the package, and usually enables removing the patch in future version. Patch files that are distributed by the author or other maintainers can be listed in $PATCHFILES. If it is desired to store any patches that should not be committed into pkgsrc, they can be kept outside the pkgsrc tree in the $LOCALPATCHES directory. The directory tree there is expected to have the same "category/package" structure as pkgsrc, and patches are expected to be stored inside these dirs (also known as $LOCALPATCHES/$PKGPATH). For example, if you want to keep a private patch for pkgsrc/graphics/png, keep it in $LOCALPATCHES/graphics/png/mypatch. All files in the named directory are expected to be patch files, and they are applied after pkgsrc patches are applied. 9.4. Other mandatory files DESCR A multi-line description of the piece of software. This should include any credits where they are due. Please bear in mind that others do not share your sense of humour (or spelling idiosyncrasies), and that others will read everything that you write here. PLIST This file governs the files that are installed on your system: all the binaries, manual pages, etc. There are other directives which may be entered in this file, to control the creation and deletion of directories, and the location of inserted files. See Chapter 11, PLIST issues for more information. 9.5. Optional files 9.5.1. Files affecting the binary package INSTALL This shell script is invoked twice by pkg_add(1). First time after package extraction and before files are moved in place, the second time after the files to install are moved in place. This can be used to do any custom procedures not possible with @exec commands in PLIST. See pkg_add(1) and pkg_create(1) for more information. DEINSTALL This script is executed before and after any files are removed. It is this script's responsibility to clean up any additional messy details around the package's installation, since all pkg_delete knows is how to delete the files created in the original distribution. See pkg_delete(1) and pkg_create(1) for more information. MESSAGE This file is displayed after installation of the package. Useful for things like legal notices on almost-free software and hints for updating config files after installing modules for apache, PHP etc. Please note that you can modify variables in it easily by using MESSAGE_SUBST in the package's Makefile: MESSAGE_SUBST+= SOMEVAR="somevalue" replaces "${SOMEVAR}" with "somevalue" in MESSAGE. ALTERNATIVES FIXME: There is no documentation on the alternatives framework. 9.5.2. Files affecting the build process Makefile.common This file contains arbitrary things that could also go into a Makefile, but its purpose is to be used by more than one package. This file should only be used when the packages that will use the file are known in advance. For other purposes it is often better to write a *.mk file and give it a good name that describes what it does. buildlink3.mk This file contains the dependency information for the buildlink3 framework (see Chapter 12, Buildlink methodology). hacks.mk This file contains workarounds for compiler bugs and similar things. It is included automatically by the pkgsrc infrastructure, so you don't need an extra .include line for it. options.mk This file contains the code for the package-specific options (see Chapter 14, Options handling) that can be selected by the user. If a package has only one or two options, it is equally acceptable to put the code directly into the Makefile. 9.5.3. Files affecting nothing at all README* These files do not take place in the creation of a package and thus are purely informative to the package developer. TODO This file contains things that need to be done to make the package even better. 9.6. work* When you type make, the distribution files are unpacked into the directory denoted by WRKDIR. It can be removed by running make clean. Besides the sources, this directory is also used to keep various timestamp files. The directory gets removed completely on clean. The default is ${.CURDIR}/work or $ {.CURDIR}/work.${MACHINE_ARCH} if OBJMACHINE is set. 9.7. files/* If you have any files that you wish to be placed in the package prior to configuration or building, you could place these files here and use a "${CP}" command in the "pre-configure" target to achieve this. Alternatively, you could simply diff the file against /dev/null and use the patch mechanism to manage the creation of this file. Chapter 10. Programming in Makefiles Table of Contents 10.1.

Passing variables to a shell command 10.2.4. Quoting guideline 10.2.5. Workaround for a bug in BSD Make Pkgsrc consists of many Makefile fragments, each of which forms a well-defined part of the pkgsrc system. Using the make(1) system as a programming language for a big system like pkgsrc requires some discipline to keep the code correct and understandable. The basic ingredients for Makefile programming are variables (which are actually macros) and shell commands. Among these shell commands may even be more complex ones like awk(1) programs. To make sure that every shell command runs as intended it is necessary to quote all variables correctly when they are used. This chapter describes some patterns, that appear quite often in Makefiles, including the pitfalls that come along with them. 10.1. Makefile variables Makefile variables contain strings that can be processed using the five operators ``='', ``+='', ``?='', ``:='', and ``!='', which are described in the make(1) man page. When a variable's value is parsed from a Makefile, the hash character ``#'' and the backslash character ``\'' are handled specially. If a backslash is followed by a newline, any whitespace immediately in front of the backslash, the backslash, the newline, and any whitespace immediately behind the newline are replaced with a single space. A backslash character and an immediately following hash character are replaced with a single hash character. Otherwise, the backslash is passed as is. In a variable assignment, any hash character that is not preceded by a backslash starts a comment that continues upto the end of the logical line. Note: Because of this parsing algorithm the only way to create a variable consisting of a single backslash is using the ``!='' operator, for example: BACKSLASH!=echo "\\". So far for defining variables. The other thing you can do with variables is evaluating them. A variable is evaluated when it is part of the right side of the ``:='' or the ``!='' operator, or directly before executing a shell command which the variable is part of. In all other cases, make(1) performs lazy evaluation, that is, variables are not evaluated until there's no other way. The ``modifiers'' mentioned in the man page also evaluate the variable. Some of the modifiers split the string into words and then operate on the words, others operate on the string as a whole. When a string is split into words, it is split as you would expect it from sh(1). No rule without exception?the .for loop does not follow the shell quoting rules but splits at sequences of whitespace. There are several types of variables that should be handled differently. Strings and two types of lists. * Strings can contain arbitrary characters. Nevertheless, you should restrict yourself to only using printable characters. Examples are PREFIX and COMMENT. * Internal lists are lists that are never exported to any shell command. Their elements are separated by whitespace. Therefore, the elements themselves cannot have embedded whitespace. Any other characters are allowed. Internal lists can be used in .for loops. Examples are DEPENDS and BUILD_DEPENDS. * External lists are lists that may be exported to a shell command. Their elements can contain any characters, including whitespace. That's why they cannot be used in .for loops. Examples are DISTFILES and MASTER_SITES. 10.1.1. Naming conventions * All variable names starting with an underscore are reserved for use by the pkgsrc infrastructure. They shall not be used by package Makefiles. * In .for loops you should use lowercase variable names for the iteration variables. * All list variables should have a ``plural'' name, e.g. PKG_OPTIONS or DISTFILES. 10.2. Code snippets This section presents you with some code snippets you should use in your own code. If you don't find anything appropriate here, you should test your code and add it here. 10.2.1. Adding things to a list STRING= foo * bar `date` INT_LIST= # empty ANOTHER_INT_LIST= apache-[0-9]*:../../www/apache EXT_LIST= # empty ANOTHER_EXT_LIST= a=b c=d INT_LIST+= ${STRING} # 1 INT_LIST+= ${ANOTHER_INT_LIST} # 2 EXT_LIST+= ${STRING:Q} # 3 EXT_LIST+= ${ANOTHER_EXT_LIST} # 4 When you add a string to an external list (example 3), it must be quoted. In all other cases, you must not add a quoting level. You must not merge internal and external lists, unless you are sure that all entries are correctly interpreted in both lists. 10.2.2. Converting an internal list into an external list EXT_LIST= # empty .for i in ${INT_LIST} EXT_LIST+= ${i:Q}"" .endfor This code converts the internal list INT_LIST into the external list EXT_LIST. As the elements of an internal list are unquoted they must be quoted here. The reason for appending "" is explained below. 10.2.3. Passing variables to a shell command Sometimes you may want to print an arbitrary string. There are many ways to get it wrong and only few that can handle every nastiness. STRING= foo bar < > * `date` $$HOME ' " EXT_LIST= string=${STRING:Q} x=second\ item all: echo ${STRING} # 1 echo "${STRING}" # 2 echo "${STRING:Q}" # 3 echo ${STRING:Q} # 4 echo x${STRING:Q} | sed 1s,.,, # 5 printf "%s\\n" ${STRING:Q}"" # 6 env ${EXT_LIST} /bin/sh -c 'echo "$$string"; echo "$$x"' Example 1 leads to a syntax error in the shell, as the characters are just copied. Example 2 leads to a syntax error too, and if you leave out the last " character from ${STRING}, date(1) will be executed. The $HOME shell variable would be evaluated, too. Example 3 outputs each space character preceded by a backslash (or not), depending on the implementation of the echo(1) command. Example 4 handles correctly every string that does not start with a dash. In that case, the result depends on the implementation of the echo(1) command. As long as you can guarantee that your input does not start with a dash, this form is appropriate. Example 5 handles even the case of a leading dash correctly. Example 6 also works with every string and is the light-weight solution, since it does not involve a pipe, which has its own problems. The EXT_LIST does not need to be quoted because the quoting has already been done when adding elements to the list. As internal lists shall not be passed to the shell, there is no example for it. 10.2.4. Quoting guideline There are many possible sources of wrongly quoted variables. This section lists some of the commonly known ones. * Whenever you use the value of a list, think about what happens to leading or trailing whitespace. If the list is a well-formed shell expression, you can apply the :M* modifier to strip leading and trailing whitespace from each word. The :M operator first splits its argument according to the rules of the shell, and then creates a new list consisting of all words that match the shell glob expression *, that is: all. One class of situations where this is needed is when adding a variable like CPPFLAGS to CONFIGURE_ARGS. If the configure script invokes other configure scripts, it strips the leading and trailing whitespace from the variable and then passes it to the other configure scripts. But these configure scripts expect the (child) CPPFLAGS variable to be the same as the parent CPPFLAGS. That's why we better pass the CPPFLAGS value properly trimmed. And here is how we do it: CPPFLAGS= # empty CPPFLAGS+= -Wundef -DPREFIX=\"${PREFIX:Q}\" CPPFLAGS+= ${MY_CPPFLAGS} CONFIGURE_ARGS+= CPPFLAGS=${CPPFLAGS:M*:Q} all: echo x${CPPFLAGS:Q}x # leading and trailing whitespace echo x${CONFIGURE_ARGS}x # properly trimmed * The example above contains one bug: The ${PREFIX} is a properly quoted shell expression, but there is the C compiler after it, which also expects a properly quoted string (this time in C syntax). The version above is therefore only correct if ${PREFIX} does not have embedded backslashes or double quotes. If you want to allow these, you have to add another layer of quoting to each variable that is used as a C string literal. You cannot use the :Q operator for it, as this operator only works for the shell. * Whenever a variable can be empty, the :Q operator can have surprising results. Here are two completely different cases which can be solved with the same trick. EMPTY= # empty empty_test: for i in a ${EMPTY:Q} c; do \ echo "$$i"; \ done for_test: .for i in a:\ a:\test.txt echo ${i:Q} echo "foo" .endfor The first example will only print two of the three lines we might have expected. This is because ${EMPTY:Q} expands to the empty string, which the shell cannot see. The workaround is to write ${EMPTY:Q}"". This pattern can be often found as ${TEST} -z ${VAR:Q} or as ${TEST} -f ${FNAME:Q} (both of these are wrong). The second example will only print three lines instead of four. The first line looks like a:\ echo foo. This is because the backslash of the value a: \ is interpreted as a line-continuation by make(1), which makes the second line the arguments of the echo(1) command from the first line. To avoid this, write ${i:Q}"". 10.2.5. Workaround for a bug in BSD Make The pkgsrc bmake program does not handle the following assignment correctly. In case _othervar_ contains a ``-'' character, one of the closing braces is included in ${VAR} after this code executes. VAR:= ${VAR:N${_othervar_:C/-//}} For a more complex code snippet and a workaround, see the package regress/ make-quoting, testcase bug1. Chapter 11. PLIST issues Table of Contents 11.1. RCS ID 11.2.

Platform-specific and differing PLISTs 11.8. Sharing directories between packages The PLIST file contains a package's "packing list", i.e. a list of files that belong to the package (relative to the ${PREFIX} directory it's been installed in) plus some additional statements - see the pkg_create(1) man page for a full list. This chapter addresses some issues that need attention when dealing with the PLIST file (or files, see below!). 11.1. RCS ID Be sure to add a RCS ID line as the first thing in any PLIST file you write: @comment $NetBSD$ 11.2. Semi-automatic PLIST generation You can use the make print-PLIST command to output a PLIST that matches any new files since the package was extracted. See Section 15.16, "Other helpful targets" for more information on this target. 11.3. Tweaking output of make print-PLIST If you have used any of the *-dirs packages, as explained in Section 11.8, "Sharing directories between packages", you may have noticed that make print-PLIST outputs a set of @comments instead of real @dirrm lines. You can also do this for specific directories and files, so that the results of that command are very close to reality. This helps a lot during the update of packages. The PRINT_PLIST_AWK variable takes a set of AWK patterns and actions that are used to filter the output of print-PLIST. You can append any chunk of AWK scripting you like to it, but be careful with quoting. For example, to get all files inside the libdata/foo directory removed from the resulting PLIST: PRINT_PLIST_AWK+= /^libdata\/foo/ { next; } And to get all the @dirrm lines referring to a specific (shared) directory converted to @comments: PRINT_PLIST_AWK+= /^@dirrm share\/specific/ { print "@comment " $$0; next; } 11.4. Variable substitution in PLIST A number of variables are substituted automatically in PLISTs when a package is installed on a system. This includes the following variables: ${MACHINE_ARCH}, ${MACHINE_GNU_ARCH} Some packages like emacs and perl embed information about which architecture they were built on into the pathnames where they install their files. To handle this case, PLIST will be preprocessed before actually used, and the symbol "${MACHINE_ARCH}" will be replaced by what uname -p gives. The same is done if the string ${MACHINE_GNU_ARCH} is embedded in PLIST somewhere - use this on packages that have GNU autoconf-created configure scripts. Legacy note There used to be a symbol "$ARCH" that was replaced by the output of uname -m, but that's no longer supported and has been removed. ${OPSYS}, ${LOWER_OPSYS}, ${OS_VERSION} Some packages want to embed the OS name and version into some paths. To do this, use these variables in the PLIST: * ${OPSYS} - output of "uname -s" * ${LOWER_OPSYS} - lowercase common name (eg. "solaris") * ${OS_VERSION} - "uname -r" For a complete list of values which are replaced by default, please look in bsd.pkg.mk (and search for PLIST_SUBST). If you want to change other variables not listed above, you can add variables and their expansions to this variable in the following way, similar to MESSAGE_SUBST (see Section 9.5, "Optional files"): PLIST_SUBST+= SOMEVAR="somevalue" This replaces all occurrences of "${SOMEVAR}" in the PLIST with "somevalue". 11.5. Man page compression Man pages should be installed in compressed form if MANZ is set (in bsd.own.mk), and uncompressed otherwise. To handle this in the PLIST file, the suffix ".gz" is appended/removed automatically for man pages according to MANZ and MANCOMPRESSED being set or not, see above for details. This modification of the PLIST file is done on a copy of it, not PLIST itself. 11.6. Changing PLIST source with PLIST_SRC To use one or more files as source for the PLIST used in generating the binary package, set the variable PLIST_SRC to the names of that file(s). The files are later concatenated using cat(1), and order of things is important. 11.7. Platform-specific and differing PLISTs Some packages decide to install a different set of files based on the operating system being used. These differences can be automatically handled by using the following files: * PLIST.common * PLIST.${OPSYS} * PLIST.${MACHINE_ARCH} * PLIST.${OPSYS}-${MACHINE_ARCH} * PLIST.common_end 11.8. Sharing directories between packages A "shared directory" is a directory where multiple (and unrelated) packages install files. These directories are problematic because you have to add special tricks in the PLIST to conditionally remove them, or have some centralized package handle them. Within pkgsrc, you'll find both approaches. If a directory is shared by a few unrelated packages, it's often not worth to add an extra package to remove it. Therefore, one simply does: @unexec ${RMDIR} %D/path/to/shared/directory 2>/dev/null || ${TRUE} in the PLISTs of all affected packages, instead of the regular "@dirrm" line. However, if the directory is shared across many packages, two different solutions are available: 1. If the packages have a common dependency, the directory can be removed in that. For example, see textproc/scrollkeeper, which removes the shared directory share/omf. 2. If the packages using the directory are not related at all (they have no common dependencies), a *-dirs package is used. From now on, we'll discuss the second solution. To get an idea of the *-dirs packages available, issue: % cd .../pkgsrc % ls -d */*-dirs Their use from other packages is very simple. The USE_DIRS variable takes a list of package names (without the "-dirs" part) together with the required version number (always pick the latest one when writing new packages). For example, if a package installs files under share/applications, it should have the following line in it: USE_DIRS+= xdg-1.1 After regenerating the PLIST using make print-PLIST, you should get the right (commented out) lines. Note that even if your package is using $X11BASE, it must not depend on the *-x11-dirs packages. Just specify the name without that part and pkgsrc (in particular, mk/dirs.mk) will take care of it.

Global preferences for native or pkgsrc software Buildlink is a framework in pkgsrc that controls what headers and libraries are seen by a package's configure and build processes. This is implemented in a two step process: 1. Symlink headers and libraries for dependencies into BUILDLINK_DIR, which by default is a subdirectory of WRKDIR. 2. Create wrapper scripts that are used in place of the normal compiler tools that translate -I${LOCALBASE}/include and -L${LOCALBASE}/lib into references to BUILDLINK_DIR. The wrapper scripts also make native compiler on some operating systems look like GCC, so that packages that expect GCC won't require modifications to build with those native compilers. This normalizes the environment in which a package is built so that the package may be built consistently despite what other software may be installed. Please note that the normal system header and library paths, e.g. /usr/include, /usr/ lib, etc., are always searched -- buildlink3 is designed to insulate the package build from non-system-supplied software. 12.1. Converting packages to use buildlink3 The process of converting packages to use the buildlink3 framework ("bl3ifying") is fairly straightforward. The things to keep in mind are: 1. Ensure that the build always calls the wrapper scripts instead of the actual toolchain. Some packages are tricky, and the only way to know for sure is the check ${WRKDIR}/.work.log to see if the wrappers are being invoked. 2. Don't override PREFIX from within the package Makefile, e.g. Java VMs, standalone shells, etc., because the code to symlink files into $ {BUILDLINK_DIR} looks for files relative to "pkg_info -qp pkgname". 3. Remember that only the buildlink3.mk files that you list in a package's Makefile are added as dependencies for that package. If a dependency on a particular package is required for its libraries and headers, then we replace: DEPENDS+= foo>=1.1.0:../../category/foo with .include "../../category/foo/buildlink3.mk" The buildlink3.mk files usually define the required dependencies. If you need a newer version of the dependency when using buildlink3.mk files, then you can define it in your Makefile; for example: BUILDLINK_API_DEPENDS.foo+= foo>=1.1.0 .include "../../category/foo/buildlink3.mk" There are several buildlink3.mk files in pkgsrc/mk that handle special package issues: * bdb.buildlink3.mk chooses either the native or a pkgsrc Berkeley DB implementation based on the values of BDB_ACCEPTED and BDB_DEFAULT. * curses.buildlink3.mk: If the system comes with neither Curses nor NCurses, this will take care to install the devel/ncurses package. * krb5.buildlink3.mk uses the value of KRB5_ACCEPTED to choose between adding a dependency on Heimdal or MIT-krb5 for packages that require a Kerberos 5 implementation. * motif.buildlink3.mk checks for a system-provided Motif installation or adds a dependency on x11/lesstif or x11/openmotif. * oss.buildlink3.mk defines several variables that may be used by packages that use the Open Sound System (OSS) API. * pgsql.buildlink3.mk will accept either Postgres 7.3 or 7.4, whichever is found installed. See the file for more information. * pthread.buildlink3.mk uses the value of PTHREAD_OPTS and checks for native pthreads or adds a dependency on devel/pth as needed. * xaw.buildlink3.mk uses the value of XAW_TYPE to choose a particular Athena widgets library. The comments in those buildlink3.mk files provide a more complete description of how to use them properly. 12.2. Writing buildlink3.mk files A package's buildlink3.mk file is included by Makefiles to indicate the need to compile and link against header files and libraries provided by the package. A buildlink3.mk file should always provide enough information to add the correct type of dependency relationship and include any other buildlink3.mk files that it needs to find headers and libraries that it needs in turn. To generate an initial buildlink3.mk file for further editing, Rene Hexel's pkgtools/createbuildlink package is highly recommended. For most packages, the following command will generate a good starting point for buildlink3.mk files: % cd pkgsrc/category/pkgdir % createbuildlink >buildlink3.mk 12.2.1. Anatomy of a buildlink3.mk file The following real-life example buildlink3.mk is taken from pkgsrc/graphics/ tiff: # $NetBSD: buildlink3.mk,v 1.7 2004/03/18 09:12:12 jlam Exp $ BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH}+ TIFF_BUILDLINK3_MK:= ${TIFF_BUILDLINK3_MK}+ .if !empty(BUILDLINK_DEPTH:M+) BUILDLINK_DEPENDS+= tiff .endif BUILDLINK_PACKAGES:= ${BUILDLINK_PACKAGES:Ntiff} BUILDLINK_PACKAGES+= tiff .if !empty(TIFF_BUILDLINK3_MK:M+) BUILDLINK_API_DEPENDS.tiff+= tiff>=3.6.1 BUILDLINK_PKGSRCDIR.tiff?= ../../graphics/tiff .endif # TIFF_BUILDLINK3_MK .include "../../devel/zlib/buildlink3.mk" .include "../../graphics/jpeg/buildlink3.mk" BUILDLINK_DEPTH:= ${BUILDLINK_DEPTH:S/+$//} The header and footer manipulate BUILDLINK_DEPTH, which is common across all buildlink3.mk files and is used to track at what depth we are including buildlink3.mk files. The first section controls if the dependency on pkg is added. BUILDLINK_DEPENDS is the global list of packages for which dependencies are added by buildlink3. The second section advises pkgsrc that the buildlink3.mk file for pkg has been included at some point. BUILDLINK_PACKAGES is the global list of packages for which buildlink3.mk files have been included. It must always be appended to within a buildlink3.mk file. The third section is protected from multiple inclusion and controls how the dependency on pkg is added. Several important variables are set in the section: * BUILDLINK_API_DEPENDS.pkg is the actual dependency recorded in the installed package; this should always be set using += to ensure that we're appending to any pre-existing list of values. This variable should be set to the first version of the package that had an API change. * BUILDLINK_PKGSRCDIR.pkg is the location of the pkg pkgsrc directory. * BUILDLINK_DEPMETHOD.pkg (not shown above) controls whether we use BUILD_DEPENDS or DEPENDS to add the dependency on pkg. The build dependency is selected by setting BUILDLINK_DEPMETHOD.pkg to "build". By default, the full dependency is used. * BUILDLINK_INCDIRS.pkg and BUILDLINK_LIBDIRS.pkg (not shown above) are lists of subdirectories of ${BUILDLINK_PREFIX.pkg} to add to the header and library search paths. These default to "include" and "lib" respectively. * BUILDLINK_CPPFLAGS.pkg (not shown above) is the list of preprocessor flags to add to CPPFLAGS, which are passed on to the configure and build phases. The "-I" option should be avoided and instead be handled using BUILDLINK_INCDIRS.pkg as above. The following variables are all optionally defined within this second section (protected against multiple inclusion) and control which package files are symlinked into ${BUILDLINK_DIR} and how their names are transformed during the symlinking: * BUILDLINK_FILES.pkg (not shown above) is a shell glob pattern relative to $ {BUILDLINK_PREFIX.pkg} to be symlinked into ${BUILDLINK_DIR}, e.g. include/ *.h. * BUILDLINK_FILES_CMD.pkg (not shown above) is a shell pipeline that outputs to stdout a list of files relative to ${BUILDLINK_PREFIX.pkg}. The resulting files are to be symlinked into ${BUILDLINK_DIR}. By default, this takes the +CONTENTS of a pkg and filters it through $ {BUILDLINK_CONTENTS_FILTER.pkg}. * BUILDLINK_CONTENTS_FILTER.pkg (not shown above) is a filter command that filters +CONTENTS input into a list of files relative to $ {BUILDLINK_PREFIX.pkg} on stdout. By default for overwrite packages, BUILDLINK_CONTENTS_FILTER.pkg outputs the contents of the include and lib directories in the package +CONTENTS, and for pkgviews packages, it outputs any libtool archives in lib directories. * BUILDLINK_TRANSFORM.pkg (not shown above) is a list of sed arguments used to transform the name of the source filename into a destination filename, e.g. -e "s|/curses.h|/ncurses.h|g". The last section includes any buildlink3.mk needed for pkg's library dependencies. Including these buildlink3.mk files means that the headers and libraries for these dependencies are also symlinked into ${BUILDLINK_DIR} whenever the pkg buildlink3.mk file is included. 12.2.2. Updating BUILDLINK_API_DEPENDS.pkg in buildlink3.mk files The situation that requires increasing the dependency listed in BUILDLINK_API_DEPENDS.pkg after a package update is when the API or interface to the header files change. In this case, BUILDLINK_API_DEPENDS.pkg should be adjusted to require at least the new package version. In some cases, the packages that depend on this new version may need their PKGREVISIONs increased and, if they have buildlink3.mk files, their BUILDLINK_API_DEPENDS.pkg adjusted, too. This is needed so pkgsrc will require the correct package dependency and not settle for an older one when building the source. BUILDLINK_ABI_DEPENDS.pkg should be increased when the binary interface or sonames (major number of the library version) of any installed shared libraries change. This is needed so that binary packages made using it will require the correct package dependency and not settle for an older one which will not contain the necessary shared libraries. See Section 17.1.6, "Handling dependencies" for more information about dependencies on other packages, including the BUILDLINK_ABI_DEPENDS and ABI_DEPENDS definitions. Please take careful consideration before adjusting BUILDLINK_API_DEPENDS.pkg or BUILDLINK_ABI_DEPENDS.pkg as we don't want to cause unneeded package deletions and rebuilds. In many cases, new versions of packages work just fine with older dependencies. Also it is not needed to set BUILDLINK_ABI_DEPENDS.pkg when it is identical to BUILDLINK_API_DEPENDS.pkg. 12.3. Writing builtin.mk files Some packages in pkgsrc install headers and libraries that coincide with headers and libraries present in the base system. Aside from a buildlink3.mk file, these packages should also include a builtin.mk file that includes the necessary checks to decide whether using the built-in software or the pkgsrc software is appropriate. The only requirements of a builtin.mk file for pkg are: 1. It should set USE_BUILTIN.pkg to either "yes" or "no" after it is included. 2. It should not override any USE_BUILTIN.pkg which is already set before the builtin.mk file is included. 3. It should be written to allow multiple inclusion. This is very important and takes careful attention to Makefile coding. 12.3.1. Anatomy of a builtin.mk file The following is the recommended template for builtin.mk files: .if !defined(IS_BUILTIN.foo) # # IS_BUILTIN.foo is set to "yes" or "no" depending on whether "foo" # genuinely exists in the system or not. # IS_BUILTIN.foo?= no # BUILTIN_PKG.foo should be set here if "foo" is built-in and its package # version can be determined. # . if !empty(IS_BUILTIN.foo:M[yY][eE][sS]) BUILTIN_PKG.foo?= foo-1.0 . endif .endif # IS_BUILTIN.foo .if !defined(USE_BUILTIN.foo) USE_BUILTIN.foo?= ${IS_BUILTIN.foo} . if defined(BUILTIN_PKG.foo) . for _depend_ in ${BUILDLINK_API_DEPENDS.foo} . if !empty(USE_BUILTIN.foo:M[yY][eE][sS]) USE_BUILTIN.foo!= \ if ${PKG_ADMIN} pmatch '${_depend_}' ${BUILTIN_PKG.foo}; then \ ${ECHO} "yes"; \ else \ ${ECHO} "no"; \ fi . endif . endfor . endif .endif # USE_BUILTIN.foo CHECK_BUILTIN.foo?= no .if !empty(CHECK_BUILTIN.foo:M[nN][oO]) # # Here we place code that depends on whether USE_BUILTIN.foo is set to # "yes" or "no". # .endif # CHECK_BUILTIN.foo The first section sets IS_BUILTIN.pkg depending on if pkg really exists in the base system. This should not be a base system software with similar functionality to pkg; it should only be "yes" if the actual package is included as part of the base system. This variable is only used internally within the builtin.mk file. The second section sets BUILTIN_PKG.pkg to the version of pkg in the base system if it exists (if IS_BUILTIN.pkg is "yes"). This variable is only used internally within the builtin.mk file. The third section sets USE_BUILTIN.pkg and is required in all builtin.mk files. The code in this section must make the determination whether the built-in software is adequate to satisfy the dependencies listed in BUILDLINK_API_DEPENDS.pkg. This is typically done by comparing BUILTIN_PKG.pkg against each of the dependencies in BUILDLINK_API_DEPENDS.pkg. USE_BUILTIN.pkg must be set to the correct value by the end of the builtin.mk file. Note that USE_BUILTIN.pkg may be "yes" even if IS_BUILTIN.pkg is "no" because we may make the determination that the built-in version of the software is similar enough to be used as a replacement. The last section is guarded by CHECK_BUILTIN.pkg, and includes code that uses the value of USE_BUILTIN.pkg set in the previous section. This typically includes, e.g., adding additional dependency restrictions and listing additional files to symlink into ${BUILDLINK_DIR} (via BUILDLINK_FILES.pkg). 12.3.2. Global preferences for native or pkgsrc software When building packages, it's possible to choose whether to set a global preference for using either the built-in (native) version or the pkgsrc version of software to satisfy a dependency. This is controlled by setting PREFER_PKGSRC and PREFER_NATIVE. These variables take values of either "yes", "no", or a list of packages. PREFER_PKGSRC tells pkgsrc to use the pkgsrc versions of software, while PREFER_NATIVE tells pkgsrc to use the built-in versions. Preferences are determined by the most specific instance of the package in either PREFER_PKGSRC or PREFER_NATIVE. If a package is specified in neither or in both variables, then PREFER_PKGSRC has precedence over PREFER_NATIVE. For example, to require using pkgsrc versions of software for all but the most basic bits on a NetBSD system, you can set: PREFER_PKGSRC= yes PREFER_NATIVE= getopt skey tcp_wrappers A package must have a builtin.mk file to be listed in PREFER_NATIVE, otherwise it is simply ignored in that list.

Disabling automatic update of the fonts databases This chapter describes the framework known as pkginstall, whose key features are: * Generic installation and manipulation of directories and files outside the pkgsrc-handled tree, LOCALBASE. * Automatic handling of configuration files during installation, provided that packages are correctly designed. * Generation and installation of system startup scripts. * Registration of system users and groups. * Registration of system shells. * Automatic updating of fonts databases. The following sections inspect each of the above points in detail. You may be thinking that many of the things described here could be easily done with simple code in the package's post-installation target (post-install). This is incorrect, as the code in them is only executed when building from source. Machines using binary packages could not benefit from it at all (as the code itself could be unavailable). Therefore, the only way to achieve any of the items described above is by means of the installation scripts, which are automatically generated by pkginstall. 13.1. Files and directories outside the installation prefix As you already know, the PLIST file holds a list of files and directories that belong to a package. The names used in it are relative to the installation prefix (${PREFIX}), which means that it cannot register files outside this directory (absolute path names are not allowed). Despite this restriction, some packages need to install files outside this location; e.g., under ${VARBASE} or ${PKG_SYSCONFDIR}. The only way to achieve this is to create such files during installation time by using the installation scripts. These scripts can run arbitrary commands, so they have the potential to create and manage files anywhere in the file system. Here is where pkginstall comes into play: it provides generic scripts to abstract the manipulation of such files and directories based on variables set in the package's Makefile. The rest of this section describes these variables. 13.1.1. Directory manipulation The following variables can be set to request the creation of directories anywhere in the file system: * MAKE_DIRS and OWN_DIRS contain a list of directories that should be created and should attempt to be destroyed by the installation scripts. The difference between the two is that the latter prompts the administrator to remove any directories that may be left after deinstallation (because they were not empty), while the former does not. * MAKE_DIRS_PERMS and OWN_DIRS_PERMS contain a list of tuples describing which directories should be created and should attempt to be destroyed by the installation scripts. Each tuple holds the following values, separated by spaces: the directory name, its owner, its group and its numerical mode. For example: MAKE_DIRS_PERMS+= ${VARBASE}/foo/private ${ROOT_USER} ${ROOT_GROUP} 0700 The difference between the two is exactly the same as their non-PERMS counterparts. 13.1.2. File manipulation Creating non-empty files outside the installation prefix is tricky because the PLIST forces all files to be inside it. To overcome this problem, the only solution is to extract the file in the known place (i.e., inside the installation prefix) and copy it to the appropriate location during installation (done by the installation scripts generated by pkginstall). We will call the former the master file in the following paragraphs, which describe the variables that can be used to automatically and consistently handle files outside the installation prefix: * CONF_FILES and SUPPORT_FILES are pairs of master and target files. During installation time, the master file is copied to the target one if and only if the latter does not exist. Upon deinstallation, the target file is removed provided that it was not modified by the installation. The difference between the two is that the latter prompts the administrator to remove any files that may be left after deinstallation (because they were not empty), while the former does not. * CONF_FILES_PERMS and SUPPORT_FILES_PERMS contain tuples describing master files as well as their target locations. For each of them, it also specifies their owner, their group and their numeric permissions, in this order. For example: SUPPORT_FILES_PERMS+= ${PREFIX}/share/somefile ${VARBASE}/somefile ${ROOT_USER} ${ROOT_GROUP} 0700 The difference between the two is exactly the same as their non-PERMS counterparts. 13.2. Configuration files Configuration files are special in the sense that they are installed in their own specific directory, PKG_SYSCONFDIR, and need special treatment during installation (most of which is automated by pkginstall). The main concept you must bear in mind is that files marked as configuration files are automatically copied to the right place (somewhere inside PKG_SYSCONFDIR) during installation if and only if they didn't exist before. Similarly, they will not be removed if they have local modifications. This ensures that administrators never lose any custom changes they may have made. 13.2.1. How PKG_SYSCONFDIR is set As said before, the PKG_SYSCONFDIR variable specifies where configuration files shall be installed. Its contents are set based upon the following variables: * PKG_SYSCONFBASE: The configuration's root directory. Defaults to ${PREFIX}/ etc although it may be overridden by the user to point to his preferred location (e.g., /etc, /etc/pkg, etc.). Packages must not use it directly. * PKG_SYSCONFSUBDIR: A subdirectory of PKG_SYSCONFBASE under which the configuration files for the package being built shall be installed. The definition of this variable only makes sense in the package's Makefile (i.e., it is not user-customizable). As an example, consider the Apache package, www/apache2, which places its configuration files under the httpd/ subdirectory of PKG_SYSCONFBASE. This should be set in the package Makefile. * PKG_SYSCONFVAR: Specifies the name of the variable that holds this package's configuration directory (if different from PKG_SYSCONFBASE). It defaults to PKGBASE's value, and is always prefixed with PKG_SYSCONFDIR. * PKG_SYSCONFDIR.${PKG_SYSCONFVAR}: Holds the directory where the configuration files for the package identified by PKG_SYSCONFVAR's shall be placed. Based on the above variables, pkginstall determines the value of PKG_SYSCONFDIR, which is the only variable that can be used within a package to refer to its configuration directory. The algorithm used to set its value is basically the following: 1. If PKG_SYSCONFDIR.${PKG_SYSCONFVAR} is set, its value is used. 2. If the previous variable is not defined but PKG_SYSCONFSUBDIR is set in the package's Makefile, the resulting value is ${PKG_SYSCONFBASE}/$ {PKG_SYSCONFSUBDIR}. 3. Otherwise, it is set to ${PKG_SYSCONFBASE}. It is worth mentioning that ${PKG_SYSCONFDIR} is automatically added to OWN_DIRS. See Section 13.1.1, "Directory manipulation" what this means. 13.2.2. Telling the software where configuration files are Given that pkgsrc (and users!) expect configuration files to be in a known place, you need to teach each package where it shall install its files. In some cases you will have to patch the package Makefiles to achieve it. If you are lucky, though, it may be as easy as passing an extra flag to the configuration script; this is the case of GNU Autoconf- generated files: CONFIGURE_ARGS+= --sysconfdir=${PKG_SYSCONFDIR} Note that this specifies where the package has to look for its configuration files, not where they will be originally installed (although the difference is never explicit, unfortunately). 13.2.3. Patching installations As said before, pkginstall automatically handles configuration files. This means that the packages themselves must not touch the contents of $ {PKG_SYSCONFDIR} directly. Bad news is that many software installation scripts will, out of the box, mess with the contents of that directory. So what is the correct procedure to fix this issue? You must teach the package (usually by manually patching it) to install any configuration files under the examples hierarchy, share/examples/${PKGBASE}/. This way, the PLIST registers them and the administrator always has the original copies available. Once the required configuration files are in place (i.e., under the examples hierarchy), the pkginstall framework can use them as master copies during the package installation to update what is in ${PKG_SYSCONFDIR}. To achieve this, the variables CONF_FILES and CONF_FILES_PERMS are used. Check out Section 13.1.2, "File manipulation" for information about their syntax and their purpose. Here is an example, taken from the mail/mutt package: EGDIR= ${PREFIX}/share/doc/mutt/samples CONF_FILES= ${EGDIR}/Muttrc ${PKG_SYSCONFDIR}/Muttrc Note that the EGDIR variable is specific to that package and has no meaning outside it. 13.2.4. Disabling handling of configuration files The automatic copying of config files can be toggled by setting the environment variable PKG_CONFIG prior to package installation. 13.3. System startup scripts System startup scripts are special files because they must be installed in a place known by the underlying OS, usually outside the installation prefix. Therefore, the same rules described in Section 13.1, "Files and directories outside the installation prefix" apply, and the same solutions can be used. However, pkginstall provides a special mechanism to handle these files. In order to provide system startup scripts, the package has to: 1. Store the script inside ${FILESDIR}, with the .sh suffix appended. Considering the print/cups package as an example, it has a cupsd.sh in its files directory. 2. Tell pkginstall to handle it, appending the name of the script, without its extension, to the RCD_SCRIPTS variable. Continuing the previous example: RCD_SCRIPTS+= cupsd Once this is done, pkginstall will do the following steps for each script in an automated fashion: 1. Process the file found in the files directory applying all the substitutions described in the FILES_SUBST variable. 2. Copy the script from the files directory to the examples hierarchy, $ {PREFIX}/share/examples/rc.d/. Note that this master file must be explicitly registered in the PLIST. 3. Add code to the installation scripts to copy the startup script from the examples hierarchy into the system-wide startup scripts directory. 13.3.1. Disabling handling of system startup scripts The automatic copying of config files can be toggled by setting the environment variable PKG_RCD_SCRIPTS prior to package installation. Note that the scripts will be always copied inside the examples hierarchy, ${PREFIX}/share/examples/ rc.d/, no matter what the value of this variable is. 13.4. System users and groups If a package needs to create special users and/or groups during installation, it can do so by using the pkginstall framework. Users can be created by adding entries to the PKG_USERS variable. Each entry has the following syntax: user:group Further specification of user details may be done by setting per-user variables. PKG_UID.user is the numeric UID for the user. PKG_GECOS.user is the user's description or comment. PKG_HOME.user is the user's home directory, and defaults to /nonexistent if not specified. PKG_SHELL.user is the user's shell, and defaults to /sbinno/login if not specified. Similarly, groups can be created by adding entries to the PKG_GROUPS variable, whose syntax is: group The numeric GID of the group may be set by defining PKG_GID.group. If a package needs to create the users and groups at an earlier stage, then it can set USERGROUP_PHASE to either configure or build to indicate the phase before which the users and groups are created. In this case, the numeric UIDs and GIDs of the created users and groups are automatically hardcoded into the final installation scripts. 13.5. System shells Packages that install system shells should register them in the shell database, /etc/shells, to make things easier to the administrator. This must be done from the installation scripts to keep binary packages working on any system. pkginstall provides an easy way to accomplish this task. When a package provides a shell interpreter, it has to set the PKG_SHELL variable to its absolute file name. This will add some hooks to the installation scripts to handle it. Consider the following example, taken from shells/zsh: PKG_SHELL= ${PREFIX}/bin/zsh 13.5.1. Disabling shell registration The automatic registration of shell interpreters can be disabled by the administrator by setting the PKG_REGISTER_SHELLS environment variable to NO. 13.6. Fonts Packages that install X11 fonts should update the database files that index the fonts within each fonts directory. This can easily be accomplished within the pkginstall framework. When a package installs X11 fonts, it must list the directories in which fonts are installed in the FONTS_DIRS.type variables, where type can be one of "ttf", "type1" or "x11". This will add hooks to the installation scripts to run the appropriate commands to update the fonts database files within each of those directories. For convenience, if the directory path is relative, it is taken to be relative to the package's installation prefix. Consider the following example, taken from fonts/dbz-ttf: FONTS_DIRS.ttf= ${PREFIX}/lib/X11/fonts/TTF 13.6.1. Disabling automatic update of the fonts databases The automatic update of fonts databases can be disabled by the administrator by setting the PKG_UPDATE_FONTS_DB environment variable to NO. Chapter 14. Options handling Table of Contents 14.1. Global default options 14.2. Converting packages to use bsd.options.mk 14.3. Option Names Many packages have the ability to be built to support different sets of features. bsd.options.mk is a framework in pkgsrc that provides generic handling of those options that determine different ways in which the packages can be built. It's possible for the user to specify exactly which sets of options will be built into a package or to allow a set of global default options apply. 14.1. Global default options Global default options are listed in PKG_DEFAULT_OPTIONS, which is a list of the options that should be built into every package if that option is supported. This variable should be set in /etc/mk.conf. 14.2. Converting packages to use bsd.options.mk The following example shows how bsd.options.mk should be used by the hypothetical ``wibble'' package, either in the package Makefile, or in a file, e.g. options.mk, that is included by the main package Makefile. PKG_OPTIONS_VAR= PKG_OPTIONS.wibble PKG_SUPPORTED_OPTIONS= wibble-foo ldap PKG_OPTIONS_OPTIONAL_GROUPS= database PKG_OPTIONS_GROUP.database= mysql pgsql PKG_SUGGESTED_OPTIONS= wibble-foo PKG_OPTIONS_LEGACY_VARS+= WIBBLE_USE_OPENLDAP:ldap PKG_OPTIONS_LEGACY_OPTS+= foo:wibble-foo .include "../../mk/bsd.prefs.mk" # this package was previously named wibble2 .if defined(PKG_OPTIONS.wibble2) PKG_LEGACY_OPTIONS+= ${PKG_OPTIONS.wibble2} PKG_OPTIONS_DEPRECATED_WARNINGS+= \ "Deprecated variable PKG_OPTIONS.wibble2 used, use ${PKG_OPTIONS_VAR} instead." .endif .include "../../mk/bsd.options.mk" # Package-specific option-handling ### ### FOO support ### .if !empty(PKG_OPTIONS:Mwibble-foo) CONFIGURE_ARGS+= --enable-foo .endif ### ### LDAP support ### .if !empty(PKG_OPTIONS:Mldap) . include "../../databases/openldap-client/buildlink3.mk" CONFIGURE_ARGS+= --enable-ldap=${BUILDLINK_PREFIX.openldap-client} .endif ### ### database support ### .if !empty(PKG_OPTIONS:Mmysql) . include "../../mk/mysql.buildlink3.mk" .endif .if !empty(PKG_OPTIONS:Mpgsql) . include "../../mk/pgsql.buildlink3.mk" .endif The first section contains the information about which build options are supported by the package, and any default options settings if needed. 1. PKG_OPTIONS_VAR is the name of the make(1) variable that the user can set to override the default options. It should be set to PKG_OPTIONS.pkgbase. Do not set it to PKG_OPTIONS.${PKGBASE}, since PKGBASE is not defined at the point where the options are processed. 2. PKG_SUPPORTED_OPTIONS is a list of build options supported by the package. 3. PKG_OPTIONS_OPTIONAL_GROUPS is a list of names of groups of mutually exclusive options. The options in each group are listed in PKG_OPTIONS_GROUP.groupname. The most specific setting of any option from the group takes precedence over all other options in the group. Options from the groups will be automatically added to PKG_SUPPORTED_OPTIONS. 4. PKG_OPTIONS_REQUIRED_GROUPS is like PKG_OPTIONS_OPTIONAL_GROUPS, but building the packages will fail if no option from the group is selected. 5. PKG_OPTIONS_NONEMPTY_SETS is a list of names of sets of options. At least one option from each set must be selected. The options in each set are listed in PKG_OPTIONS_SET.setname. Options from the sets will be automatically added to PKG_SUPPORTED_OPTIONS. Building the package will fail if no option from the set is selected. 6. PKG_SUGGESTED_OPTIONS is a list of build options which are enabled by default. 7. PKG_OPTIONS_LEGACY_VARS is a list of "USE_VARIABLE:option" pairs that map legacy /etc/mk.conf variables to their option counterparts. Pairs should be added with "+=" to keep the listing of global legacy variables. A warning will be issued if the user uses a legacy variable. 8. PKG_OPTIONS_LEGACY_OPTS is a list of "old-option:new-option" pairs that map options that have been renamed to their new counterparts. Pairs should be added with "+=" to keep the listing of global legacy options. A warning will be issued if the user uses a legacy option. 9. PKG_LEGACY_OPTIONS is a list of options implied by deprecated variables used. This can be used for cases that neither PKG_OPTIONS_LEGACY_VARS nor PKG_OPTIONS_LEGACY_OPTS can handle, e. g. when PKG_OPTIONS_VAR is renamed. 10. PKG_OPTIONS_DEPRECATED_WARNINGS is a list of warnings about deprecated variables or options used, and what to use instead. A package should never modify PKG_DEFAULT_OPTIONS or the variable named in PKG_OPTIONS_VAR. These are strictly user-settable. To suggest a default set of options, use PKG_SUGGESTED_OPTIONS. PKG_OPTIONS_VAR must be defined before including bsd.options.mk. If none of PKG_SUPPORTED_OPTIONS, PKG_OPTIONS_OPTIONAL_GROUPS, and PKG_OPTIONS_REQUIRED_GROUPS are defined (as can happen with platform-specific options if none of them is supported on the current platform), PKG_OPTIONS is set to the empty list and the package is otherwise treated as not using the options framework. After the inclusion of bsd.options.mk, the variable PKG_OPTIONS contains the list of selected build options, properly filtered to remove unsupported and duplicate options. The remaining sections contain the logic that is specific to each option. The correct way to check for an option is to check whether it is listed in PKG_OPTIONS: .if !empty(PKG_OPTIONS:Moption) 14.3. Option Names Options that enable similar features in different packages (like optional support for a library) should use a common name in all packages that support it (like the name of the library). If another package already has an option with the same meaning, use the same name. Options that enable features specific to one package, where it's unlikely that another (unrelated) package has the same (or a similar) optional feature, should use a name prefixed with pkgname-. If a group of related packages share an optional feature specific to that group, prefix it with the name of the "main" package (e. g. djbware-errno-hack). For new options, add a line to mk/defaults/options.description. Lines have two fields, separated by tab. The first field is the option name, the second its description. The description should be a whole sentence (starting with an uppercase letter and ending with a period) that describes what enabling the option does. E. g. "Enable ispell support." The file is sorted by option names. Chapter 15. The build process Table of Contents 15.1. Introduction 15.2. Program location 15.3. Directories used during the build process 15.4.

Introduction This chapter gives a detailed description on how a package is built. Building a package is separated into different phases (for example fetch, build, install), all of which are described in the following sections. Each phase is splitted into so-called stages, which take the name of the containing phase, prefixed by one of pre-, do- or post-. (Examples are pre-configure, post-build.) Most of the actual work is done in the do-* stages. The basic steps for building a program are always the same. First the program's source (distfile) must be brought to the local system and then extracted. After any pkgsrc-specific patches to compile properly are applied, the software can be configured, then built (usually by compiling), and finally the generated binaries, etc. can be put into place on the system. 15.2. Program location Before outlining the process performed by the NetBSD package system in the next section, here's a brief discussion on where programs are installed, and which variables influence this. The automatic variable PREFIX indicates where all files of the final program shall be installed. It is usually set to LOCALBASE (/usr/pkg), or CROSSBASE for pkgs in the "cross" category. The value of PREFIX needs to be put into the various places in the program's source where paths to these files are encoded. See Section 9.3, "patches/*" and Section 17.3.1, "Shared libraries - libtool" for more details. When choosing which of these variables to use, follow the following rules: * PREFIX always points to the location where the current pkg will be installed. When referring to a pkg's own installation path, use "${PREFIX} ". * LOCALBASE is where all non-X11 pkgs are installed. If you need to construct a -I or -L argument to the compiler to find includes and libraries installed by another non-X11 pkg, use "${LOCALBASE}". The name LOCALBASE stems from FreeBSD, which installed all packages in /usr/local. As pkgsrc leaves /usr/local for the system administrator, this variable is a misnomer. * X11BASE is where the actual X11 distribution (from xsrc, etc.) is installed. When looking for standard X11 includes (not those installed by a pkg), use "${X11BASE}". * X11-based packages are special in that they may be installed in either X11BASE or LOCALBASE. Usually, X11 packages should be installed under LOCALBASE whenever possible. Note that you will need to include ../../mk/x11.buildlink3.mk in them to request the presence of X11 and to get the right compilation flags. Even though, there are some packages that cannot be installed under LOCALBASE: those that come with app-defaults files. These packages are special and they must be placed under X11BASE. To accomplish this, set either USE_X11BASE or USE_IMAKE in your package. Some notes: If you need to find includes or libraries installed by a pkg that has USE_IMAKE or USE_X11BASE in its pkg Makefile, you need to look in both ${X11BASE} and ${LOCALBASE}. To force installation of all X11 packages in LOCALBASE, the pkgtools/xpkgwedge package is enabled by default. * X11PREFIX should be used to refer to the installed location of an X11 package. X11PREFIX will be set to X11BASE if xpkgwedge is not installed, and to LOCALBASE if xpkgwedge is installed. * If xpkgwedge is installed, it is possible to have some packages installed in X11BASE and some in LOCALBASE. To determine the prefix of an installed package, the EVAL_PREFIX definition can be used. It takes pairs in the format "DIRNAME=", and the make(1) variable DIRNAME will be set to the prefix of the installed package , or "${X11PREFIX}" if the package is not installed. This is best illustrated by example. The following lines are taken from pkgsrc/wm/scwm/Makefile: EVAL_PREFIX+= GTKDIR=gtk+ CONFIGURE_ARGS+= --with-guile-prefix=${LOCALBASE:Q} CONFIGURE_ARGS+= --with-gtk-prefix=${GTKDIR:Q} CONFIGURE_ARGS+= --enable-multibyte Specific defaults can be defined for the packages evaluated using EVAL_PREFIX, by using a definition of the form: GTKDIR_DEFAULT= ${LOCALBASE} where GTKDIR corresponds to the first definition in the EVAL_PREFIX pair. * Within ${PREFIX}, packages should install files according to hier(7), with the exception that manual pages go into ${PREFIX}/man, not ${PREFIX}/share/ man. 15.3. Directories used during the build process When building a package, a number of directories is used to store source files, temporary files, pkgsrc-internal files, and so on. These directories are explained here. Some of the directory variables contain relative pathnames. There are two common base directories for these relative directories: PKGSRCDIR/PKGPATH is used for directories that are pkgsrc-specific. WRKSRC is used for directories inside the package itself. PKGSRCDIR This is an absolute pathname that points to the pkgsrc root directory. Generally, you don't need it. PKGPATH This is a pathname relative to PKGSRCDIR that points to the current package. WRKDIR This is an absolute pathname pointing to the directory where all work takes place. The distfiles are extraced to this directory. It also contains temporary directories and log files used by the various pkgsrc frameworks, like buildlink or the wrappers. WRKSRC This is an absolute pathname pointing to the directory where the distfiles are extracted. It is usually a direct subdirectory of WRKDIR, and often it's the only directory entry that isn't hidden. This variable may be changed by a package Makefile. 15.4. Running a phase You can run a particular phase by typing make phase, where phase is the name of the phase. This will automatically run all phases that are required for this phase. The default phase is build, that is, when you run make without parameters in a package directory, the package will be built, but not installed. 15.5. The fetch phase The first step in building a package is to fetch the distribution files (distfiles) from the sites that are providing them. This is the task of the fetch phase. 15.5.1. What to fetch and where to get it from In simple cases, MASTER_SITES defines all URLs from where the distfile, whose name is derived from the DISTNAME variable, is fetched. The more complicated cases are described below. The variable DISTFILES specifies the list of distfiles that have to be fetched. Its value defaults to ${DISTNAME}${EXTRACT_SUFX}, so that most packages don't need to define it at all. EXTRACT_SUFX is .tar.gz by default, but can be changed freely. Note that if your package requires additional distfiles to the default one, you cannot just append the additional filenames using the += operator, but you have write for example: DISTFILES= ${DISTNAME}${EXTRACT_SUFX} additional-files.tar.gz Each of the distfiles is fetched from a list of sites, usually MASTER_SITES. If the package has multiple DISTFILES or multiple PATCHFILES from different sites, you can set SITES.distfile to the list of URLs where the file distfile (including the suffix) can be found. DISTFILES= ${DISTNAME}${EXTRACT_SUFX} DISTFILES+= foo-file.tar.gz SITES.foo-file.tar.gz= \ http://www.somewhere.com/somehow/ \ http://www.somewhereelse.com/mirror/somehow/ When actually fetching the distfiles, each item from MASTER_SITES or SITES.* gets the name of each distfile appended to it, without an intermediate slash. Therefore, all site values have to end with a slash or other separator character. This allows for example to set MASTER_SITES to a URL of a CGI script that gets the name of the distfile as a parameter. In this case, the definition would look like: MASTER_SITES= http://www.example.com/download.cgi?file= There are some predefined values for MASTER_SITES, which can be used in packages. The names of the variables should speak for themselves. ${MASTER_SITE_APACHE} ${MASTER_SITE_BACKUP} ${MASTER_SITE_CYGWIN} ${MASTER_SITE_DEBIAN} ${MASTER_SITE_FREEBSD} ${MASTER_SITE_FREEBSD_LOCAL} ${MASTER_SITE_GNOME} ${MASTER_SITE_GNU} ${MASTER_SITE_GNUSTEP} ${MASTER_SITE_IFARCHIVE} ${MASTER_SITE_KDE} ${MASTER_SITE_MOZILLA} ${MASTER_SITE_MYSQL} ${MASTER_SITE_OPENOFFICE} ${MASTER_SITE_PERL_CPAN} ${MASTER_SITE_PGSQL} ${MASTER_SITE_R_CRAN} ${MASTER_SITE_SOURCEFORGE} ${MASTER_SITE_SOURCEFORGE_JP} ${MASTER_SITE_SUNSITE} ${MASTER_SITE_SUSE} ${MASTER_SITE_TEX_CTAN} ${MASTER_SITE_XCONTRIB} ${MASTER_SITE_XEMACS} If you choose one of these predefined sites, you may want to specify a subdirectory of that site. Since these macros may expand to more than one actual site, you must use the following construct to specify a subdirectory: MASTER_SITES= ${MASTER_SITE_GNU:=subdirectory/name/} MASTER_SITES= ${MASTER_SITE_SOURCEFORGE:=project_name/} Note the trailing slash after the subdirectory name. 15.5.2. How are the files fetched? The fetch phase makes sure that all the distfiles exist in a local directory (DISTDIR), which can be set by the pkgsrc user). If the files do not exist, they are fetched using commands of the form ${FETCH_CMD} ${FETCH_BEFORE_ARGS} ${site}${file} ${FETCH_AFTER_ARGS} where ${site} varies through several possibilities in turn: first, MASTER_SITE_OVERRIDE is tried, then the sites specified in either SITES.file if defined, else MASTER_SITES or PATCH_SITES, as applies, then finally the value of MASTER_SITE_BACKUP. The order of all except the first can be optionally sorted by the user, via setting either MASTER_SORT_AWK or MASTER_SORT_REGEX. 15.6. The checksum phase After the distfile(s) are fetched, their checksum is generated and compared with the checksums stored in the distinfo file. If the checksums don't match, the build is aborted. This is to ensure the same distfile is used for building, and that the distfile wasn't changed, e.g. by some malign force, deliberately changed distfiles on the master distribution site or network lossage. 15.7. The extract phase When the distfiles are present on the local system, they need to be extracted, as they usually come in the form of some compressed archive format. By default, all DISTFILES are extracted. If you only need some of them, you can set the EXTRACT_ONLY variable to the list of those files. Extracting the files is usually done by a little program, mk/scripts/extract, which already knows how to extract various archive formats, so most likely you will not need to change anything here. But if you need, the following variables may help you: EXTRACT_OPTS_{BIN,LHA,PAX,RAR,TAR,ZIP,ZOO} Use these variables to override the default options for an extract command, which are defined in mk/scripts/extract. EXTRACT_USING This variable can be set to pax, tar or an absolute pathname pointing to the command with which tar archives should be extracted. If the extract program doesn't serve your needs, you can also override the EXTRACT_CMD variable, which holds the command used for extracting the files. This command is executed in the ${WRKSRC} directory. During execution of this command, the shell variable extract_file holds the absolute pathname of the file that is going to be extracted. And if that still does not suffice, you can override the do-extract target in the package Makefile. 15.8. The patch phase After extraction, all the patches named by the PATCHFILES, those present in the patches subdirectory of the package as well as in $LOCALPATCHES/$PKGPATH (e.g. /usr/local/patches/graphics/png) are applied. Patchfiles ending in .Z or .gz are uncompressed before they are applied, files ending in .orig or .rej are ignored. Any special options to patch(1) can be handed in PATCH_DIST_ARGS. See Section 9.3, "patches/*" for more details. By default patch(1) is given special args to make it fail if the patches apply with some lines of fuzz. Please fix (regen) the patches so that they apply cleanly. The rationale behind this is that patches that don't apply cleanly may end up being applied in the wrong place, and cause severe harm there. 15.9. The tools phase This is covered in Chapter 16, Tools needed for building or running. 15.10. The wrapper phase This phase creates wrapper programs for the compilers and linkers. The following variables can be used to tweak the wrappers. ECHO_WRAPPER_MSG The command used to print progress messages. Does nothing by default. Set to ${ECHO} to see the progress messages. WRAPPER_DEBUG This variable can be set to yes (default) or no, depending on whether you want additional information in the wrapper log file. WRAPPER_UPDATE_CACHE This variable can be set to yes or no, depending on whether the wrapper should use its cache, which will improve the speed. The default value is yes, but is forced to no if the platform does not support it. WRAPPER_REORDER_CMDS A list of reordering commands. A reordering command has the form reorder:l: lib1:lib2. It ensures that that -llib1 occurs before -llib2. WRAPPER_TRANSFORM_CMDS A list of transformation commands. [TODO: investigate further] 15.11. The configure phase Most pieces of software need information on the header files, system calls, and library routines which are available on the platform they run on. The process of determining this information is known as configuration, and is usually automated. In most cases, a script is supplied with the distfiles, and its invocation results in generation of header files, Makefiles, etc. If the package contains a configure script, this can be invoked by setting HAS_CONFIGURE to "yes". If the configure script is a GNU autoconf script, you should set GNU_CONFIGURE to "yes" instead. What happens in the configure phase is roughly: .for d in ${CONFIGURE_DIRS} cd ${WRKSRC} && cd ${d} && env ${CONFIGURE_ENV} \ ${CONFIGURE_SCRIPT} ${CONFIGURE_ARGS} .endfor CONFIGURE_DIRS (default: ".") is a list of pathnames relative to WRKSRC. In each of these directories, the configure script is run with the environment CONFIGURE_ENV and arguments CONFIGURE_ARGS. The variables CONFIGURE_ENV, CONFIGURE_SCRIPT (default: "./configure") and CONFIGURE_ARGS may all be changed by the package. If the program uses an Imakefile for configuration, the appropriate steps can be invoked by setting USE_IMAKE to "yes". (If you only want the package installed in ${X11PREFIX} but xmkmf not being run, set USE_X11BASE instead.) 15.12. The build phase For building a package, a rough equivalent of the following code is executed. .for d in ${BUILD_DIRS} cd ${WRKSRC} && cd ${d} && env ${MAKE_ENV} \ ${MAKE_PROGRAM} ${BUILD_MAKE_FLAGS} \ -f ${MAKEFILE} ${BUILD_TARGET} .endfor BUILD_DIRS (default: ".") is a list of pathnames relative to WRKSRC. In each of these directories, MAKE_PROGRAM is run with the environment MAKE_ENV and arguments BUILD_MAKE_FLAGS. The variables MAKE_ENV, BUILD_MAKE_FLAGS, MAKEFILE and BUILD_TARGET may all be changed by the package. The default value of MAKE_PROGRAM is "gmake" if USE_TOOLS contains "gmake", "make" otherwise. The default value of MAKEFILE is "Makefile", and BUILD_TARGET defaults to "all". 15.13. The test phase [TODO] 15.14. The install phase Once the build stage has completed, the final step is to install the software in public directories, so users can access the programs and files. In the install phase, a rough equivalent of the following code is executed. Additionally, before and after this code, much magic is performed to do consistency checks, registering the package, and so on. .for d in ${INSTALL_DIRS} cd ${WRKSRC} && cd ${d} && env ${MAKE_ENV} \ ${MAKE_PROGRAM} ${INSTALL_MAKE_FLAGS} \ -f ${MAKEFILE} ${BUILD_TARGET} .endfor The variable's meanings are analogous to the ones in the build phase. INSTALL_DIRS defaults to BUILD_DIRS. INSTALL_TARGET is "install" by default, plus "install.man" if USE_IMAKE is defined. In the install phase, the following variables are useful. They are all variations of the install(1) command that have the owner, group and permissions preset. INSTALL is the plain install command. The specialized variants, together with their intended use, are: INSTALL_PROGRAM_DIR directories that contain binaries INSTALL_SCRIPT_DIR directories that contain scripts INSTALL_LIB_DIR directories that contain shared and static libraries INSTALL_DATA_DIR directories that contain data files INSTALL_MAN_DIR directories that contain man pages INSTALL_PROGRAM binaries that can be stripped from debugging symbols INSTALL_SCRIPT binaries that cannot be stripped INSTALL_GAME game binaries INSTALL_LIB shared and static libraries INSTALL_DATA data files INSTALL_GAME_DATA data files for games INSTALL_MAN man pages Some other variables are: INSTALLATION_DIRS A list of directories relative to PREFIX that are created by pkgsrc at the beginning of the install phase. If this variable is set, NO_MTREE="yes" is assumed, which means that the package claims to create all needed directories itself before installing files to it. Therefore this variable should only be set in Makefiles that are under control of the package's author. The directories are created with the correct ownership, depending on their name. 15.15. The package phase [TODO] 15.16. Other helpful targets pre/post-* For any of the main targets described in the previous section, two auxiliary targets exist with "pre-" and "post-" used as a prefix for the main target's name. These targets are invoked before and after the main target is called, allowing extra configuration or installation steps be performed from a package's Makefile, for example, which a program's configure script or install target omitted. do-* Should one of the main targets do the wrong thing, and should there be no variable to fix this, you can redefine it with the do-* target. (Note that redefining the target itself instead of the do-* target is a bad idea, as the pre-* and post-* targets won't be called anymore, etc.) You will not usually need to do this. reinstall If you did a make install and you noticed some file was not installed properly, you can repeat the installation with this target, which will ignore the "already installed" flag. deinstall This target does a pkg_delete(1) in the current directory, effectively de-installing the package. The following variables can be used to tune the behaviour: PKG_VERBOSE Add a "-v" to the pkg_delete(1) command. DEINSTALLDEPENDS Remove all packages that require (depend on) the given package. This can be used to remove any packages that may have been pulled in by a given package, e.g. if make deinstall DEINSTALLDEPENDS=1 is done in pkgsrc/x11/kde, this is likely to remove whole KDE. Works by adding "-R" to the pkg_delete(1) command line. update This target causes the current package to be updated to the latest version. The package and all depending packages first get de-installed, then current versions of the corresponding packages get compiled and installed. This is similar to manually noting which packages are currently installed, then performing a series of make deinstall and make install (or whatever UPDATE_TARGET is set to) for these packages. You can use the "update" target to resume package updating in case a previous make update was interrupted for some reason. However, in this case, make sure you don't call make clean or otherwise remove the list of dependent packages in WRKDIR. Otherwise, you lose the ability to automatically update the current package along with the dependent packages you have installed. Resuming an interrupted make update will only work as long as the package tree remains unchanged. If the source code for one of the packages to be updated has been changed, resuming make update will most certainly fail! The following variables can be used either on the command line or in /etc/ mk.conf to alter the behaviour of make update: UPDATE_TARGET Install target to recursively use for the updated package and the dependent packages. Defaults to DEPENDS_TARGET if set, "install" otherwise for make update. e.g. make update UPDATE_TARGET=package NOCLEAN Don't clean up after updating. Useful if you want to leave the work sources of the updated packages around for inspection or other purposes. Be sure you eventually clean up the source tree (see the "clean-update" target below) or you may run into troubles with old source code still lying around on your next make or make update. REINSTALL Deinstall each package before installing (making DEPENDS_TARGET). This may be necessary if the "clean-update" target (see below) was called after interrupting a running make update. DEPENDS_TARGET Allows you to disable recursion and hardcode the target for packages. The default is "update" for the update target, facilitating a recursive update of prerequisite packages. Only set DEPENDS_TARGET if you want to disable recursive updates. Use UPDATE_TARGET instead to just set a specific target for each package to be installed during make update (see above). clean-update Clean the source tree for all packages that would get updated if make update was called from the current directory. This target should not be used if the current package (or any of its depending packages) have already been de-installed (e.g., after calling make update) or you may lose some packages you intended to update. As a rule of thumb: only use this target before the first time you run make update and only if you have a dirty package tree (e.g., if you used NOCLEAN). If you are unsure about whether your tree is clean, you can either perform a make clean at the top of the tree, or use the following sequence of commands from the directory of the package you want to update (before running make update for the first time, otherwise you lose all the packages you wanted to update!): # make clean-update # make clean CLEANDEPENDS=YES # make update The following variables can be used either on the command line or in /etc/ mk.conf to alter the behaviour of make clean-update: CLEAR_DIRLIST After make clean, do not reconstruct the list of directories to update for this package. Only use this if make update successfully installed all packages you wanted to update. Normally, this is done automatically on make update, but may have been suppressed by the NOCLEAN variable (see above). info This target invokes pkg_info(1) for the current package. You can use this to check which version of a package is installed. readme This target generates a README.html file, which can be viewed using a browser such as www/firefox or www/links. The generated files contain references to any packages which are in the PACKAGES directory on the local host. The generated files can be made to refer to URLs based on FTP_PKG_URL_HOST and FTP_PKG_URL_DIR. For example, if I wanted to generate README.html files which pointed to binary packages on the local machine, in the directory /usr/packages, set FTP_PKG_URL_HOST=file://localhost and FTP_PKG_URL_DIR=/usr/packages. The ${PACKAGES} directory and its subdirectories will be searched for all the binary packages. readme-all Use this target to create a file README-all.html which contains a list of all packages currently available in the NetBSD Packages Collection, together with the category they belong to and a short description. This file is compiled from the pkgsrc/*/README.html files, so be sure to run this after a make readme. cdrom-readme This is very much the same as the "readme" target (see above), but is to be used when generating a pkgsrc tree to be written to a CD-ROM. This target also produces README.html files, and can be made to refer to URLs based on CDROM_PKG_URL_HOST and CDROM_PKG_URL_DIR. show-distfiles This target shows which distfiles and patchfiles are needed to build the package. (DISTFILES and PATCHFILES, but not patches/*) show-downlevel This target shows nothing if the package is not installed. If a version of this package is installed, but is not the version provided in this version of pkgsrc, then a warning message is displayed. This target can be used to show which of your installed packages are downlevel, and so the old versions can be deleted, and the current ones added. show-pkgsrc-dir This target shows the directory in the pkgsrc hierarchy from which the package can be built and installed. This may not be the same directory as the one from which the package was installed. This target is intended to be used by people who may wish to upgrade many packages on a single host, and can be invoked from the top-level pkgsrc Makefile by using the "show-host-specific-pkgs" target. show-installed-depends This target shows which installed packages match the current package's DEPENDS. Useful if out of date dependencies are causing build problems. check-shlibs After a package is installed, check all its binaries and (on ELF platforms) shared libraries to see if they find the shared libs they need. Run by default if PKG_DEVELOPER is set in /etc/mk.conf. print-PLIST After a "make install" from a new or upgraded pkg, this prints out an attempt to generate a new PLIST from a find -newer work/.extract_done. An attempt is made to care for shared libs etc., but it is strongly recommended to review the result before putting it into PLIST. On upgrades, it's useful to diff the output of this command against an already existing PLIST file. If the package installs files via tar(1) or other methods that don't update file access times, be sure to add these files manually to your PLIST, as the "find -newer" command used by this target won't catch them! See Section 11.3, "Tweaking output of make print-PLIST" for more information on this target. bulk-package Used to do bulk builds. If an appropriate binary package already exists, no action is taken. If not, this target will compile, install and package it (and its depends, if PKG_DEPENDS is set properly. See Section 6.3.1, "Configuration"). After creating the binary package, the sources, the just-installed package and its required packages are removed, preserving free disk space. Beware that this target may deinstall all packages installed on a system! bulk-install Used during bulk-installs to install required packages. If an up-to-date binary package is available, it will be installed via pkg_add(1). If not, make bulk-package will be executed, but the installed binary won't be removed. A binary package is considered "up-to-date" to be installed via pkg_add(1) if: * None of the package's files (Makefile, ...) were modified since it was built. * None of the package's required (binary) packages were modified since it was built. Beware that this target may deinstall all packages installed on a system! Chapter 16. Tools needed for building or running Table of Contents 16.1. Tools for pkgsrc builds 16.2. Tools needed by packages 16.3. Tools provided by platforms The USE_TOOLS definition is used both internally by pkgsrc and also for individual packages to define what commands are needed for building a package (like BUILD_DEPENDS) or for later run-time of an installed packaged (such as DEPENDS). If the native system provides an adequate tool, then in many cases, a pkgsrc package will not be used. When building a package, the replacement tools are made available in a directory (as symlinks or wrapper scripts) that is early in the executable search path. Just like the buildlink system, this helps with consistent builds. A tool may be needed to help build a specific package. For example, perl, GNU make (gmake) or yacc may be needed. Also a tool may be needed, for example, because the native system's supplied tool may be inefficient for building a package with pkgsrc. For example, a package may need GNU awk, bison (instead of yacc) or a better sed. The tools used by a package can be listed by running make show-tools. 16.1. Tools for pkgsrc builds The default set of tools used by pkgsrc is defined in bsd.pkg.mk. This includes standard Unix tools, such as: cat, awk, chmod, test, and so on. These can be seen by running: make show-var VARNAME=USE_TOOLS. If a package needs a specific program to build then the USE_TOOLS variable can be used to define the tools needed. 16.2. Tools needed by packages In the following examples, the :pkgsrc means to use the pkgsrc version and not the native version for a build dependency. And the :run means that it is used for a run-time dependencies also (and becomes a DEPENDS). The default is a build dependency which can be set with :build. (So in this example, it is the same as gmake:build and pkg-config:build.) USE_TOOLS+= mktemp:pkgsrc USE_TOOLS+= gmake perl:run pkg-config When using the tools framework, a TOOLS_PATH.foo variable is defined which contains the full path to the appropriate tool. For example, TOOLS_PATH.bash could be "/bin/bash" on Linux systems. If you always need a pkgsrc version of the tool at run-time, then just use DEPENDS instead. 16.3. Tools provided by platforms When improving or porting pkgsrc to a new platform, have a look at (or create) the corresponding platform specific make file fragment under pkgsrc/mk/tools/ tools.${OPSYS}.mk which defines the name of the common tools. For example: .if exists(/usr/bin/bzcat) TOOLS_PLATFORM.bzcat?= /usr/bin/bzcat .elif exists(/usr/bin/bzip2) TOOLS_PLATFORM.bzcat?= /usr/bin/bzip2 -cd .endif TOOLS_PLATFORM.true?= true # shell builtin Chapter 17.

Portability of packages One appealing feature of pkgsrc is that it runs on many different platforms. As a result, it is important to ensure, where possible, that packages in pkgsrc are portable. This chapter mentions some particular details you should pay attention to while working on pkgsrc. 17.1.2. How to pull in user-settable variables from mk.conf The pkgsrc user can configure pkgsrc by overriding several variables in the file pointed to by MAKECONF, which is /etc/mk.conf by default. When you want to use those variables in the preprocessor directives of make(1) (for example .if or .for), you need to include the file ../../mk/bsd.prefs.mk before, which in turn loads the user preferences. But note that some variables may not be completely defined after ../../mk/ bsd.prefs.mk has been included, as they may contain references to variables that are not yet defined. In shell commands this is no problem, since variables are actually macros, which are only expanded when they are used. But in the preprocessor directives mentioned above and in dependency lines (of the form target: dependencies) the variables are expanded at load time. Note Currently there is no exhaustive list of all variables that tells you whether they can be used at load time or only at run time, but it is in preparation. 17.1.3. User interaction Occasionally, packages require interaction from the user, and this can be in a number of ways: * When fetching the distfiles, some packages require user interaction such as entering username/password or accepting a license on a web page. * When extracting the distfiles, some packages may ask for passwords. * help to configure the package before it is built * help during the build process * help during the installation of a package The INTERACTIVE_STAGE definition is provided to notify the pkgsrc mechanism of an interactive stage which will be needed, and this should be set in the package's Makefile, e.g.: INTERACTIVE_STAGE= build Multiple interactive stages can be specified: INTERACTIVE_STAGE= configure install 17.1.4. Handling licenses A package may be covered by a license which the user has or has not agreed to accept. For these cases, pkgsrc contains a mechanism to note that a package is covered by a particular license, and the package cannot be built unless the user has accepted the license. (Installation of binary packages are not currently subject to this mechanism.) Packages with licenses that are either Open Source according to the Open Source Initiative or Free according to the Free Software Foundation will not be marked with a license tag. Packages with licenses that have not been determined to meet either definition will be marked with a license tag referring to the license. This will prevent building unless pkgsrc is informed that the license is acceptable, and enables displaying the license. The license tag mechanism is intended to address copyright-related issues surrounding building, installing and using a package, and not to address redistribution issues (see RESTRICTED and NO_SRC_ON_FTP, etc.). However, the above definition of licenses for which tags are not needed implies that packages with redistribution restrictions should have tags. Denoting that a package is covered by a particular license is done by placing the license in pkgsrc/licenses and setting the LICENSE variable to a string identifying the license, e.g. in graphics/xv: LICENSE= xv-license When trying to build, the user will get a notice that the package is covered by a license which has not been accepted: % make ===> xv-3.10anb9 has an unacceptable license: xv-license. ===> To view the license, enter "/usr/bin/make show-license". ===> To indicate acceptance, add this line to your /etc/mk.conf: ===> ACCEPTABLE_LICENSES+=xv-license *** Error code 1 The license can be viewed with make show-license, and if it is considered appropriate, the line printed above can be added to /etc/mk.conf to indicate acceptance of the particular license: ACCEPTABLE_LICENSES+=xv-license When adding a package with a new license, the license text should be added to pkgsrc/licenses for displaying. A list of known licenses can be seen in this directory as well as by looking at the list of (commented out) ACCEPTABLE_LICENSES variable settings in pkgsrc/mk/defaults/mk.conf. The use of LICENSE=shareware, LICENSE=no-commercial-use, and similar language is deprecated because it does not crisply refer to a particular license text. Another problem with such usage is that it does not enable a user to denote acceptance of the license for a single package without accepting the same license text for another package. In particular, this can be inappropriate when e.g. one accepts a particular license to indicate to pkgsrc that a fee has been paid. 17.1.5. Restricted packages Some licenses restrict how software may be re-distributed. In order to satisfy these restrictions, the package system defines five make variables that can be set to note these restrictions: * RESTRICTED This variable should be set whenever a restriction exists (regardless of its kind). Set this variable to a string containing the reason for the restriction. * NO_BIN_ON_CDROM Binaries may not be placed on CD-ROM. Set this variable to ${RESTRICTED} whenever a binary package may not be included on a CD-ROM. * NO_BIN_ON_FTP Binaries may not be placed on an FTP server. Set this variable to $ {RESTRICTED} whenever a binary package may not not be made available on the Internet. * NO_SRC_ON_CDROM Distfiles may not be placed on CD-ROM. Set this variable to ${RESTRICTED} if re-distribution of the source code or other distfile(s) is not allowed on CD-ROMs. * NO_SRC_ON_FTP Distfiles may not be placed on FTP. Set this variable to ${RESTRICTED} if re-distribution of the source code or other distfile(s) via the Internet is not allowed. Please note that the use of NO_PACKAGE, IGNORE, NO_CDROM, or other generic make variables to denote restrictions is deprecated, because they unconditionally prevent users from generating binary packages! 17.1.6. Handling dependencies Your package may depend on some other package being present - and there are various ways of expressing this dependency. pkgsrc supports the BUILD_DEPENDS and DEPENDS definitions, the USE_TOOLS definition, as well as dependencies via buildlink3.mk, which is the preferred way to handle dependencies, and which uses the variables named above. See Chapter 12, Buildlink methodology for more information. The basic difference between the two variables is as follows: The DEPENDS definition registers that pre-requisite in the binary package so it will be pulled in when the binary package is later installed, whilst the BUILD_DEPENDS definition does not, marking a dependency that is only needed for building the package. This means that if you only need a package present whilst you are building, it should be noted as a BUILD_DEPENDS. The format for a BUILD_DEPENDS and a DEPENDS definition is: :../..// Please note that the "pre-req-package-name" may include any of the wildcard version numbers recognized by pkg_info(1). 1. If your package needs another package's binaries or libraries to build or run, and if that package has a buildlink3.mk file available, use it: .include "../../graphics/jpeg/buildlink3.mk" 2. If your package needs to use another package to build itself and there is no buildlink3.mk file available, use the BUILD_DEPENDS definition: BUILD_DEPENDS+= autoconf-2.13:../../devel/autoconf 3. If your package needs a library with which to link and again there is no buildlink3.mk file available, this is specified using the DEPENDS definition. For example: DEPENDS+= xpm-3.4j:../../graphics/xpm You can also use wildcards in package dependences: DEPENDS+= xpm-[0-9]*:../../graphics/xpm Note that such wildcard dependencies are retained when creating binary packages. The dependency is checked when installing the binary package and any package which matches the pattern will be used. Wildcard dependencies should be used with care. The "-[0-9]*" should be used instead of "-*" to avoid potentially ambiguous matches such as "tk-postgresql" matching a "tk-*" DEPENDS. Wildcards can also be used to specify that a package will only build against a certain minimum version of a pre-requisite: DEPENDS+= tiff>=3.5.4:../../graphics/tiff This means that the package will build against version 3.5.4 of the tiff library or newer. Such a dependency may be warranted if, for example, the API of the library has changed with version 3.5.4 and a package would not compile against an earlier version of tiff. Please note that such dependencies should only be updated if a package requires a newer pre-requisite, but not to denote recommendations such as ABI changes that do not prevent a package from building correctly. Such recommendations can be expressed using ABI_DEPENDS: ABI_DEPENDS+= tiff>=3.6.1:../../graphics/tiff In addition to the above DEPENDS line, this denotes that while a package will build against tiff>=3.5.4, at least version 3.6.1 is recommended. ABI_DEPENDS entries will be turned into dependencies unless explicitly ignored (in which case a warning will be printed). To ignore these ABI dependency recommendations and just use the required DEPENDS, set USE_ABI_DEPENDS=NO. This may make it easier and faster to update packages built using pkgsrc, since older compatible dependencies can continue to be used. This is useful for people who watch their rebuilds very carefully; it is not very good as a general-purpose hammer. If you use it, you need to be mindful of possible ABI changes, including those from the underlying OS. Packages that are built with recommendations ignored may not be uploaded to ftp.NetBSD.org by developers and should not be used across different systems that may have different versions of binary packages installed. For security fixes, please update the package vulnerabilities file. See Section 17.1.10, "Handling packages with security problems" for more information. 4. If your package needs some executable to be able to run correctly and if there's no buildlink3.mk file, this is specified using the DEPENDS variable. The print/lyx package needs to be able to execute the latex binary from the teTeX package when it runs, and that is specified: DEPENDS+= teTeX-[0-9]*:../../print/teTeX The comment about wildcard dependencies from previous paragraph applies here, too. If your package needs files from another package to build, add the relevant distribution files to DISTFILES, so they will be extracted automatically. See the print/ghostscript package for an example. (It relies on the jpeg sources being present in source form during the build.) Please also note the BUILD_USES_MSGFMT and BUILD_USES_GETTEXT_M4 definitions, which are provided as convenience definitions. The former works out whether msgfmt(1) is part of the base system, and, if it isn't, installs the devel/ gettext package. The latter adds a build dependency on either an installed version of an older gettext package, or if it isn't, installs the devel/ gettext-m4 package. 17.1.7. Handling conflicts with other packages Your package may conflict with other packages a user might already have installed on his system, e.g. if your package installs the same set of files like another package in our pkgsrc tree. In this case you can set CONFLICTS to a space-separated list of packages (including version string) your package conflicts with. For example, x11/Xaw3d and x11/Xaw-Xpm install the same shared library, thus you set in pkgsrc/x11/Xaw3d/Makefile: CONFLICTS= Xaw-Xpm-[0-9]* and in pkgsrc/x11/Xaw-Xpm/Makefile: CONFLICTS= Xaw3d-[0-9]* Packages will automatically conflict with other packages with the name prefix and a different version string. "Xaw3d-1.5" e.g. will automatically conflict with the older version "Xaw3d-1.3". 17.1.8. Packages that cannot or should not be built There are several reasons why a package might be instructed to not build under certain circumstances. If the package builds and runs on most platforms, the exceptions should be noted with NOT_FOR_PLATFORM. If the package builds and runs on a small handful of platforms, set ONLY_FOR_PLATFORM instead. Both ONLY_FOR_PLATFORM and NOT_FOR_PLATFORM are OS triples (OS-version-platform) that can use glob-style wildcards. If the package should be skipped (for example, because it provides functionality already provided by the system), set PKG_SKIP_REASON to a descriptive message. If the package should fail because some preconditions are not met, set PKG_FAIL_REASON to a descriptive message. 17.1.9. Packages which should not be deleted, once installed To ensure that a package may not be deleted, once it has been installed, the PKG_PRESERVE definition should be set in the package Makefile. This will be carried into any binary package that is made from this pkgsrc entry. A "preserved" package will not be deleted using pkg_delete(1) unless the "-f" option is used. 17.1.10. Handling packages with security problems When a vulnerability is found, this should be noted in localsrc/security/ advisories/pkg-vulnerabilities, and after committing that file, use make upload in the same directory to update the file on ftp.NetBSD.org. After fixing the vulnerability by a patch, its PKGREVISION should be increased (this is of course not necessary if the problem is fixed by using a newer release of the software). Also, if the fix should be applied to the stable pkgsrc branch, be sure to submit a pullup request! Binary packages already on ftp.NetBSD.org will be handled semi-automatically by a weekly cron job. 17.1.11. How to handle incrementing versions when fixing an existing package When making fixes to an existing package it can be useful to change the version number in PKGNAME. To avoid conflicting with future versions by the original author, a "nb1", "nb2", ... suffix can be used on package versions by setting PKGREVISION=1 (2, ...). The "nb" is treated like a "." by the pkg tools. e.g. DISTNAME= foo-17.42 PKGREVISION= 9 will result in a PKGNAME of "foo-17.42nb9". When a new release of the package is released, the PKGREVISION should be removed, e.g. on a new minor release of the above package, things should be like: DISTNAME= foo-17.43 PKGREVISION should be incremented for any non-trivial change in the resulting binary package. Without a PKGREVISION bump, someone with the previous version installed has no way of knowing that their package is out of date. Thus, changes without increasing PKGREVISION are essentially labeled "this is so trivial that no reasonable person would want to upgrade", and this is the rough test for when increasing PKGREVISION is appropriate. Examples of changes that do not merit increasing PKGREVISION are: Changing HOMEPAGE, MAINTAINER, or comments in Makefile. Changing build variables if the resulting binary package is the same. Changing DESCR. Adding PKG_OPTIONS if the default options don't change. Examples of changes that do merit an increase to PKGREVISION include: Security fixes Changes or additions to a patch file Changes to the PLIST PKGREVISION must also be incremented when dependencies have ABI changes. 17.1.12. Substituting variable text in the package files (the SUBST framework) When you want to replace the same text in multiple files or when the replacement text varies, patches alone cannot help. This is where the SUBST framework comes in. It provides an easy-to-use interface for replacing text in files. Example: SUBST_CLASSES+= fix-paths SUBST_STAGE.fix-paths= pre-configure SUBST_MESSAGE.fix-paths= Fixing absolute paths. SUBST_FILES.fix-paths= src/*.c SUBST_FILES.fix-paths+= scripts/*.sh SUBST_SED.fix-paths= -e 's,"/usr/local,"${PREFIX},g' SUBST_SED.fix-paths+= -e 's,"/var/log,"${VARBASE}/log,g' SUBST_CLASSES is a list of identifiers that are used to identify the different SUBST blocks that are defined. The SUBST framework is heavily used by pkgsrc, so it is important to always use the += operator with this variable. Otherwise some substitutions may be skipped. The remaining variables of each SUBST block are parameterized with the identifier from the first line (fix-paths in this case.) They can be seen as parameters to a function call. SUBST_STAGE.* specifies the stage at which the replacement will take place. All combinations of pre-, do- and post- together with a phase name are possible, though only few are actually used. Most commonly used are post-patch and pre-configure. Of these two, pre-configure should be preferred because then it is possible to run bmake patch and have the state after applying the patches but before making any other changes. This is especially useful when you are debugging a package in order to create new patches for it. Similarly, post-build is preferred over pre-install, because the install phase should generally be kept as simple as possible. When you use post-build, you have the same files in the working directory that will be installed later, so you can check if the substitution has succeeded. SUBST_MESSAGE.* is an optional text that is printed just before the substitution is done. SUBST_FILES.* is the list of shell globbing patterns that specifies the files in which the substitution will take place. The patterns are interpreted relatively to the WRKSRC directory. SUBST_SED.* is a list of arguments to sed(1) that specify the actual substitution. Every sed command should be prefixed with -e, so that all SUBST blocks look uniform. There are some more variables, but they are so seldomly used that they are only documented in the mk/subst.mk file. 17.2. Fixing problems in the fetch phase 17.2.1. Packages whose distfiles aren't available for plain downloading If you need to download from a dynamic URL you can set DYNAMIC_MASTER_SITES and a make fetch will call files/getsite.sh with the name of each file to download as an argument, expecting it to output the URL of the directory from which to download it. graphics/ns-cult3d is an example of this usage. If the download can't be automated, because the user must submit personal information to apply for a password, or must pay for the source, or whatever, you can set FETCH_MESSAGE to a list of lines that are displayed to the user before aborting the build. Example: FETCH_MESSAGE= "Please download the files" FETCH_MESSAGE+= " "${DISTFILES:Q} FETCH_MESSAGE+= "manually from "${MASTER_SITES:Q}"." 17.2.2. How to handle modified distfiles with the 'old' name Sometimes authors of a software package make some modifications after the software was released, and they put up a new distfile without changing the package's version number. If a package is already in pkgsrc at that time, the checksum will no longer match. The contents of the new distfile should be compared against the old one before changing anything, to make sure the distfile was really updated on purpose, and that no trojan horse or so crept in. Then, the correct way to work around this is to set DIST_SUBDIR to a unique directory name, usually based on PKGNAME_NOREV. In case this happens more often, PKGNAME can be used (thus including the nbX suffix) or a date stamp can be appended, like ${PKGNAME_NOREV}-YYYYMMDD. Do not forget regenerating the distinfo file after that, since it contains the DIST_SUBDIR path in the filenames. Furthermore, a mail to the package's authors seems appropriate telling them that changing distfiles after releases without changing the file names is not good practice. 17.3. Fixing problems in the configure phase 17.3.1. Shared libraries - libtool pkgsrc supports many different machines, with different object formats like a.out and ELF, and varying abilities to do shared library and dynamic loading at all. To accompany this, varying commands and options have to be passed to the compiler, linker, etc. to get the Right Thing, which can be pretty annoying especially if you don't have all the machines at your hand to test things. The devel/libtool pkg can help here, as it just "knows" how to build both static and dynamic libraries from a set of source files, thus being platform-independent. Here's how to use libtool in a pkg in seven simple steps: 1. Add USE_LIBTOOL=yes to the package Makefile. 2. For library objects, use "${LIBTOOL} --mode=compile ${CC}" in place of "$ {CC}". You could even add it to the definition of CC, if only libraries are being built in a given Makefile. This one command will build both PIC and non-PIC library objects, so you need not have separate shared and non-shared library rules. 3. For the linking of the library, remove any "ar", "ranlib", and "ld -Bshareable" commands, and instead use: ${LIBTOOL} --mode=link ${CC} -o ${.TARGET:.a=.la} ${OBJS:.o=.lo} \ -rpath ${PREFIX}/lib -version-info major:minor Note that the library is changed to have a .la extension, and the objects are changed to have a .lo extension. Change OBJS as necessary. This automatically creates all of the .a, .so.major.minor, and ELF symlinks (if necessary) in the build directory. Be sure to include "-version-info", especially when major and minor are zero, as libtool will otherwise strip off the shared library version. From the libtool manual: So, libtool library versions are described by three integers: CURRENT The most recent interface number that this library implements. REVISION The implementation number of the CURRENT interface. AGE The difference between the newest and oldest interfaces that this library implements. In other words, the library implements all the interface numbers in the range from number `CURRENT - AGE' to `CURRENT'. If two libraries have identical CURRENT and AGE numbers, then the dynamic linker chooses the library with the greater REVISION number. The "-release" option will produce different results for a.out and ELF (excluding symlinks) in only one case. An ELF library of the form "libfoo-release.so.x.y" will have a symlink of "libfoo.so.x.y" on an a.out platform. This is handled automatically. The "-rpath argument" is the install directory of the library being built. In the PLIST, include only the .la file, the other files will be added automatically. 4. When linking shared object (.so) files, i.e. files that are loaded via dlopen(3), NOT shared libraries, use "-module -avoid-version" to prevent them getting version tacked on. The PLIST file gets the foo.so entry. 5. When linking programs that depend on these libraries before they are installed, preface the cc(1) or ld(1) line with "${LIBTOOL} --mode=link", and it will find the correct libraries (static or shared), but please be aware that libtool will not allow you to specify a relative path in -L (such as "-L../somelib"), because it expects you to change that argument to be the .la file. e.g. ${LIBTOOL} --mode=link ${CC} -o someprog -L../somelib -lsomelib should be changed to: ${LIBTOOL} --mode=link ${CC} -o someprog ../somelib/somelib.la and it will do the right thing with the libraries. 6. When installing libraries, preface the install(1) or cp(1) command with "$ {LIBTOOL} --mode=install", and change the library name to .la. e.g. ${LIBTOOL} --mode=install ${BSD_INSTALL_DATA} ${SOMELIB:.a=.la} ${PREFIX}/lib This will install the static .a, shared library, any needed symlinks, and run ldconfig(8). 7. In your PLIST, include only the .la file (this is a change from previous behaviour). 17.3.2. Using libtool on GNU packages that already support libtool Add USE_LIBTOOL=yes to the package Makefile. This will override the package's own libtool in most cases. For older libtool using packages, libtool is made by ltconfig script during the do-configure step; you can check the libtool script location by doing make configure; find work*/ -name libtool. LIBTOOL_OVERRIDE specifies which libtool scripts, relative to WRKSRC, to override. By default, it is set to "libtool */libtool */*/libtool". If this does not match the location of the package's libtool script(s), set it as appropriate. If you do not need *.a static libraries built and installed, then use SHLIBTOOL_OVERRIDE instead. If your package makes use of the platform-independent library for loading dynamic shared objects, that comes with libtool (libltdl), you should include devel/libltdl/buildlink3.mk. Some packages use libtool incorrectly so that the package may not work or build in some circumstances. Some of the more common errors are: * The inclusion of a shared object (-module) as a dependent library in an executable or library. This in itself isn't a problem if one of two things has been done: 1. The shared object is named correctly, i.e. libfoo.la, not foo.la 2. The -dlopen option is used when linking an executable. * The use of libltdl without the correct calls to initialisation routines. The function lt_dlinit() should be called and the macro LTDL_SET_PRELOADED_SYMBOLS included in executables. 17.3.3. GNU Autoconf/Automake If a package needs GNU autoconf or automake to be executed to regenerate the configure script and Makefile.in makefile templates, then they should be executed in a pre-configure target. For packages that need only autoconf: AUTOCONF_REQD= 2.50 # if default version is not good enough USE_TOOLS+= autoconf # use "autoconf213" for autoconf-2.13 ... pre-configure: cd ${WRKSRC}; autoconf ... and for packages that need automake and autoconf: AUTOMAKE_REQD= 1.7.1 # if default version is not good enough USE_TOOLS+= automake # use "automake14" for automake-1.4 ... pre-configure: cd ${WRKSRC}; \ aclocal; autoheader; \ automake -a --foreign -i; autoconf ... Packages which use GNU Automake will almost certainly require GNU Make. There are times when the configure process makes additional changes to the generated files, which then causes the build process to try to re-execute the automake sequence. This is prevented by touching various files in the configure stage. If this causes problems with your package you can set AUTOMAKE_OVERRIDE= NO in the package Makefile. 17.4. Fixing problems in the build phase The most common failures when building a package are that some platforms do not provide certain header files, functions or libraries, or they provide the functions in a library that the original package author didn't know. To work around this, you can rewrite the source code in most cases so that it does not use the missing functions or provides a replacement function. 17.4.1. Compiling C and C++ code conditionally If a package already comes with a GNU configure script, the preferred way to fix the build failure is to change the configure script, not the code. In the other cases, you can utilize the C preprocessor, which defines certain macros depending on the operating system and hardware architecture it compiles for. These macros can be queried using for example #if defined(__i386). Almost every operating system, hardware architecture and compiler has its own macro. For example, if the macros __GNUC__, __i386__ and __NetBSD__ are all defined, you know that you are using NetBSD on an i386 compatible CPU, and your compiler is GCC. The list of the following macros for hardware and operating system depends on the compiler that is used. For example, if you want to conditionally compile code on Solaris, don't use __sun__, as the SunPro compiler does not define it. Use __sun instead. 17.4.1.1. C preprocessor macros to identify the operating system To distinguish between 4.4 BSD-derived systems and the rest of the world, you should use the following code. #include #if (defined(BSD) && BSD >= 199306) /* BSD-specific code goes here */ #else /* non-BSD-specific code goes here */ #endif If this distinction is not fine enough, you can also test for the following macros. FreeBSD __FreeBSD__ DragonFly __DragonFly__ Interix __INTERIX Linux linux, __linux, __linux__ NetBSD __NetBSD__ OpenBSD __OpenBSD__ Solaris sun, __sun 17.4.1.2. C preprocessor macros to identify the hardware architecture i386 i386, __i386, __i386__ MIPS __mips SPARC sparc, __sparc 17.4.1.3. C preprocessor macros to identify the compiler GCC __GNUC__ (major version), __GNUC_MINOR__ SunPro __SUNPRO_C (0x570 for version 5.7) SunPro C++ __SUNPRO_CC (0x580 for version 5.8) 17.4.2. How to handle compiler bugs Some source files trigger bugs in the compiler, based on combinations of compiler version and architecture and almost always relation to optimisation being enabled. Common symptoms are gcc internal errors or never finishing compiling a file. Typically, a workaround involves testing the MACHINE_ARCH and compiler version, disabling optimisation for that combination of file, MACHINE_ARCH and compiler, and documenting it in pkgsrc/doc/HACKS. See that file for a number of examples. 17.4.3. Undefined reference to "..." This compiler error often means that a package did not link to a shared library it needs. The following functions are known to cause this error message over and over. +-----------------------------------------------------+ | Function |Library |Affected platforms| |-------------------------+--------+------------------| |accept, bind, connect |-lsocket|Solaris | |-------------------------+--------+------------------| |crypt |-lcrypt |DragonFly, NetBSD | |-------------------------+--------+------------------| |dlopen, dlsym |-ldl |Linux | |-------------------------+--------+------------------| |gethost* |-lnsl |Solaris | |-------------------------+--------+------------------| |inet_aton |-lresolv|Solaris | |-------------------------+--------+------------------| |nanosleep, sem_*, timer_*|-lrt |Solaris | |-------------------------+--------+------------------| |openpty |-lutil |Linux | +-----------------------------------------------------+ To fix these linker errors, it is often sufficient to say LIBS.OperatingSystem+ = -lfoo to the package Makefile and then say bmake clean; bmake. 17.5. Fixing problems in the install phase 17.5.1. Creating needed directories The BSD-compatible install supplied with some operating systems cannot create more than one directory at a time. As such, you should call ${INSTALL_*_DIR} like this: ${INSTALL_DATA_DIR} ${PREFIX}/dir1 ${INSTALL_DATA_DIR} ${PREFIX}/dir2 You can also just append "dir1 dir2" to the INSTALLATION_DIRS variable, which will automatically do the right thing. 17.5.2. Where to install documentation In general, documentation should be installed into ${PREFIX}/share/doc/$ {PKGBASE} or ${PREFIX}/share/doc/${PKGNAME} (the latter includes the version number of the package). Many modern packages using GNU autoconf allow to set the directory where HTML documentation is installed with the "--with-html-dir" option. Sometimes using this flag is needed because otherwise the documentation ends up in ${PREFIX}/ share/doc/html or other places. An exception to the above is that library API documentation generated with the textproc/gtk-doc tools, for use by special browsers (devhelp) should be left at their default location, which is ${PREFIX}/share/gtk-doc. Such documentation can be recognized from files ending in .devhelp or .devhelp2. (It is also acceptable to install such files in ${PREFIX}/share/doc/${PKGBASE} or ${PREFIX} /share/doc/${PKGNAME}; the .devhelp* file must be directly in that directory then, no additional subdirectory level is allowed in this case. This is usually achieved by using "--with-html-dir=${PREFIX}/share/doc". ${PREFIX}/share/ gtk-doc is preferred though.) 17.5.3. Installing score files Certain packages, most of them in the games category, install a score file that allows all users on the system to record their highscores. In order for this to work, the binaries need to be installed setgid and the score files owned by the appropriate group and/or owner (traditionally the "games" user/group). The following variables, documented in more detail in mk/defaults/mk.conf, control this behaviour: SETGIDGAME, GAMEDATAMODE, GAMEGRP, GAMEMODE, GAMEOWN. Note that per default, setgid installation of games is disabled; setting SETGIDGAME=YES will set all the other variables accordingly. A package should therefor never hard code file ownership or access permissions but rely on INSTALL_GAME and INSTALL_GAME_DATA to set these correctly. 17.5.4. Packages containing perl scripts If your package contains interpreted perl scripts, set REPLACE_PERL to ensure that the proper interpreter path is set. REPLACE_PERL should contain a list of scripts, relative to WRKSRC, that you want adjusted. 17.5.5. Packages with hardcoded paths to other interpreters Your package may also contain scripts with hardcoded paths to other interpreters besides (or as well as) perl. To correct the full pathname to the script interpreter, you need to set the following definitions in your Makefile (we shall use tclsh in this example): REPLACE_INTERPRETER+= tcl REPLACE.tcl.old= .*/bin/tclsh REPLACE.tcl.new= ${PREFIX}/bin/tclsh REPLACE_FILES.tcl= # list of tcl scripts which need to be fixed, # relative to ${WRKSRC}, just as in REPLACE_PERL Note Before March 2006, these variables were called _REPLACE.* and _REPLACE_FILES.*. 17.5.6. Packages installing perl modules Makefiles of packages providing perl5 modules should include the Makefile fragment ../../lang/perl5/module.mk. It provides a do-configure target for the standard perl configuration for such modules as well as various hooks to tune this configuration. See comments in this file for details. Perl5 modules will install into different places depending on the version of perl used during the build process. To address this, pkgsrc will append lines to the PLIST corresponding to the files listed in the installed .packlist file generated by most perl5 modules. This is invoked by defining PERL5_PACKLIST to a space-separated list of paths to packlist files, e.g.: PERL5_PACKLIST= ${PERL5_SITEARCH}/auto/Pg/.packlist The variables PERL5_SITELIB, PERL5_SITEARCH, and PERL5_ARCHLIB represent the three locations in which perl5 modules may be installed, and may be used by perl5 packages that don't have a packlist. These three variables are also substituted for in the PLIST. 17.5.7. Packages installing info files Some packages install info files or use the "makeinfo" or "install-info" commands. INFO_FILES should be defined in the package Makefile so that INSTALL and DEINSTALL scripts will be generated to handle registration of the info files in the Info directory file. The "install-info" command used for the info files registration is either provided by the system, or by a special purpose package automatically added as dependency if needed. PKGINFODIR is the directory under ${PREFIX} where info files are primarily located. PKGINFODIR defaults to "info" and can be overridden by the user. The info files for the package should be listed in the package PLIST; however any split info files need not be listed. A package which needs the "makeinfo" command at build time must add "makeinfo" to USE_TOOLS in its Makefile. If a minimum version of the "makeinfo" command is needed it should be noted with the TEXINFO_REQD variable in the package Makefile. By default, a minimum version of 3.12 is required. If the system does not provide a makeinfo command or if it does not match the required minimum, a build dependency on the devel/gtexinfo package will be added automatically. The build and installation process of the software provided by the package should not use the install-info command as the registration of info files is the task of the package INSTALL script, and it must use the appropriate makeinfo command. To achieve this goal, the pkgsrc infrastructure creates overriding scripts for the install-info and makeinfo commands in a directory listed early in PATH. The script overriding install-info has no effect except the logging of a message. The script overriding makeinfo logs a message and according to the value of TEXINFO_REQD either runs the appropriate makeinfo command or exit on error. 17.5.8. Packages installing man pages All packages that install manual pages should install them into the same directory, so that there is one common place to look for them. In pkgsrc, this place is ${PREFIX}/${PKGMANDIR}, and this expression should be used in packages. The default for PKGMANDIR is "man". Another often-used value is "share/man". Note The support for a custom PKGMANDIR is far from complete. The PLIST files can just use man/ as the top level directory for the man page file entries, and the pkgsrc framework will convert as needed. In all other places, the correct PKGMANDIR must be used. Packages that are configured with GNU_CONFIGURE set as "yes", by default will use the ./configure --mandir switch to set where the man pages should be installed. The path is GNU_CONFIGURE_MANDIR which defaults to ${PREFIX}/$ {PKGMANDIR}. Packages that use GNU_CONFIGURE but do not use --mandir, can set CONFIGURE_HAS_MANDIR to "no". Or if the ./configure script uses a non-standard use of --mandir, you can set GNU_CONFIGURE_MANDIR as needed. See Section 11.5, "Man page compression" for information on installation of compressed manual pages. 17.5.9. Packages installing GConf2 data files If a package installs .schemas or .entries files, used by GConf2, you need to take some extra steps to make sure they get registered in the database: 1. Include ../../devel/GConf2/schemas.mk instead of its buildlink3.mk file. This takes care of rebuilding the GConf2 database at installation and deinstallation time, and tells the package where to install GConf2 data files using some standard configure arguments. It also disallows any access to the database directly from the package. 2. Ensure that the package installs its .schemas files under ${PREFIX}/share/ gconf/schemas. If they get installed under ${PREFIX}/etc, you will need to manually patch the package. 3. Check the PLIST and remove any entries under the etc/gconf directory, as they will be handled automatically. See Section 7.14, "How do I change the location of configuration files?" for more information. 4. Define the GCONF2_SCHEMAS variable in your Makefile with a list of all .schemas files installed by the package, if any. Names must not contain any directories in them. 5. Define the GCONF2_ENTRIES variable in your Makefile with a list of all .entries files installed by the package, if any. Names must not contain any directories in them. 17.5.10. Packages installing scrollkeeper data files If a package installs .omf files, used by scrollkeeper, you need to take some extra steps to make sure they get registered in the database: 1. Include ../../textproc/scrollkeeper/omf.mk instead of its buildlink3.mk file. This takes care of rebuilding the scrollkeeper database at installation and deinstallation time, and disallows any access to it directly from the package. 2. Check the PLIST and remove any entries under the libdata/scrollkeeper directory, as they will be handled automatically. 3. Remove the share/omf directory from the PLIST. It will be handled by scrollkeeper. 17.5.11. Packages installing X11 fonts If a package installs font files, you will need to rebuild the fonts database in the directory where they get installed at installation and deinstallation time. This can be automatically done by using the pkginstall framework. You can list the directories where fonts are installed in the FONTS_DIRS.type variables, where type can be one of "ttf", "type1" or "x11". Also make sure that the database file fonts.dir is not listed in the PLIST. Note that you should not create new directories for fonts; instead use the standard ones to avoid that the user needs to manually configure his X server to find them. 17.5.12. Packages installing GTK2 modules If a package installs GTK2 immodules or loaders, you need to take some extra steps to get them registered in the GTK2 database properly: 1. Include ../../x11/gtk2/modules.mk instead of its buildlink3.mk file. This takes care of rebuilding the database at installation and deinstallation time. 2. Set GTK2_IMMODULES=YES if your package installs GTK2 immodules. 3. Set GTK2_LOADERS=YES if your package installs GTK2 loaders. 4. Patch the package to not touch any of the GTK2 databases directly. These are: * libdata/gtk-2.0/gdk-pixbuf.loaders * libdata/gtk-2.0/gtk.immodules 5. Check the PLIST and remove any entries under the libdata/gtk-2.0 directory, as they will be handled automatically. 17.5.13. Packages installing SGML or XML data If a package installs SGML or XML data files that need to be registered in system-wide catalogs (like DTDs, sub-catalogs, etc.), you need to take some extra steps: 1. Include ../../textproc/xmlcatmgr/catalogs.mk in your Makefile, which takes care of registering those files in system-wide catalogs at installation and deinstallation time. 2. Set SGML_CATALOGS to the full path of any SGML catalogs installed by the package. 3. Set XML_CATALOGS to the full path of any XML catalogs installed by the package. 4. Set SGML_ENTRIES to individual entries to be added to the SGML catalog. These come in groups of three strings; see xmlcatmgr(1) for more information (specifically, arguments recognized by the 'add' action). Note that you will normally not use this variable. 5. Set XML_ENTRIES to individual entries to be added to the XML catalog. These come in groups of three strings; see xmlcatmgr(1) for more information (specifically, arguments recognized by the 'add' action). Note that you will normally not use this variable. 17.5.14. Packages installing extensions to the MIME database If a package provides extensions to the MIME database by installing .xml files inside ${PREFIX}/share/mime/packages, you need to take some extra steps to ensure that the database is kept consistent with respect to these new files: 1. Include ../../databases/shared-mime-info/mimedb.mk (avoid using the buildlink3.mk file from this same directory, which is reserved for inclusion from other buildlink3.mk files). It takes care of rebuilding the MIME database at installation and deinstallation time, and disallows any access to it directly from the package. 2. Check the PLIST and remove any entries under the share/mime directory, except for files saved under share/mime/packages. The former are handled automatically by the update-mime-database program, but the latter are package-dependent and must be removed by the package that installed them in the first place. 3. Remove any share/mime/* directories from the PLIST. They will be handled by the shared-mime-info package. 17.5.15. Packages using intltool If a package uses intltool during its build, include the ../../textproc/ intltool/buildlink3.mk file, which forces it to use the intltool package provided by pkgsrc, instead of the one bundled with the distribution file. This tracks intltool's build-time dependencies and uses the latest available version; this way, the package benefits of any bug fixes that may have appeared since it was released. 17.5.16. Packages installing startup scripts If a package contains a rc.d script, it won't be copied into the startup directory by default, but you can enable it, by adding the option PKG_RCD_SCRIPTS=YES in /etc/mk.conf. This option will copy the scripts into / etc/rc.d when a package is installed, and it will automatically remove the scripts when the package is deinstalled. 17.5.17. Packages installing TeX modules If a package installs TeX packages into the texmf tree, the ls-R database of the tree needs to be updated. Note Except the main TeX packages such as teTeX-texmf, packages should install files into PKG_LOCALTEXMFPREFIX, not PKG_TEXMFPREFIX. 1. Include ../../print/teTeX/module.mk instead of ../../mk/tex.buildlink3.mk. This takes care of rebuilding the ls-R database at installation and deinstallation time. 2. If your package installs files into a texmf tree other than the one at PKG_LOCALTEXMFPREFIX, set TEXMFDIRS to the list of all texmf trees that need database update. If your package also installs font map files that need to be registered using updmap, set TEX_FONTMAPS to the list of all such font map files. Then updmap will be run automatically at installation/deinstallation to enable/ disable font map files for TeX output drivers. 3. Make sure that none of ls-R databases are included in PLIST, as they will be removed only by the teTeX-bin package. 17.6. Feedback to the author If you have found any bugs in the package you make available, if you had to do special steps to make it run under NetBSD or if you enhanced the software in various other ways, be sure to report these changes back to the original author of the program! With that kind of support, the next release of the program can incorporate these fixes, and people not using the NetBSD packages system can win from your efforts. Support the idea of free software! Chapter 18. Debugging To check out all the gotchas when building a package, here are the steps that I do in order to get a package working. Please note this is basically the same as what was explained in the previous sections, only with some debugging aids. * Be sure to set PKG_DEVELOPER=1 in /etc/mk.conf * Install pkgtools/url2pkg, create a directory for a new package, change into it, then run url2pkg: % mkdir /usr/pkgsrc/category/examplepkg % cd /usr/pkgsrc/category/examplepkg % url2pkg http://www.example.com/path/to/distfile.tar.gz * Edit the Makefile as requested. * Fill in the DESCR file * Run make configure * Add any dependencies glimpsed from documentation and the configure step to the package's Makefile. * Make the package compile, doing multiple rounds of % make % pkgvi ${WRKSRC}/some/file/that/does/not/compile % mkpatches % patchdiff % mv ${WRKDIR}/.newpatches/* patches % make mps % make clean Doing as non-root user will ensure that no files are modified that shouldn't be, especially during the build phase. mkpatches, patchdiff and pkgvi are from the pkgtools/pkgdiff package. * Look at the Makefile, fix if necessary; see Section 9.1, "Makefile". * Generate a PLIST: # make install # make print-PLIST >PLIST # make deinstall # make install # make deinstall You usually need to be root to do this. Look if there are any files left: # make print-PLIST If this reveals any files that are missing in PLIST, add them. * Now that the PLIST is OK, install the package again and make a binary package: # make reinstall # make package * Delete the installed package: # pkg_delete blub * Repeat the above make print-PLIST command, which shouldn't find anything now: # make print-PLIST * Reinstall the binary package: # pkgadd .../blub.tgz * Play with it. Make sure everything works. * Run pkglint from pkgtools/pkglint, and fix the problems it reports: # pkglint * Submit (or commit, if you have cvs access); see Chapter 19, Submitting and Committing. Chapter 19. Submitting and Committing Table of Contents 19.1. Submitting binary packages 19.2. Submitting source packages (for non-NetBSD-developers) 19.3. General notes when adding, updating, or removing packages 19.4. Committing: Importing a package into CVS 19.5. Updating a package to a newer version 19.6. Moving a package in pkgsrc 19.1. Submitting binary packages Our policy is that we accept binaries only from pkgsrc developers to guarantee that the packages don't contain any trojan horses etc. This is not to annoy anyone but rather to protect our users! You're still free to put up your home-made binary packages and tell the world where to get them. NetBSD developers doing bulk builds and wanting to upload them please see Section 6.3.8, "Uploading results of a bulk build". 19.2. Submitting source packages (for non-NetBSD-developers) First, check that your package is complete, compiles and runs well; see Chapter 18, Debugging and the rest of this document. Next, generate an uuencoded gzipped tar(1) archive that contains all files that make up the package. Finally, send-pr with category "pkg", a synopsis which includes the package name and version number, a short description of your package (contents of the COMMENT variable or DESCR file are OK) and attach the archive to your PR. If you want to submit several packages, please send a separate PR for each one, it's easier for us to track things that way. Alternatively, you can also import new packages into pkgsrc-wip ("pkgsrc work-in-progress"); see the homepage at http://pkgsrc-wip.sourceforge.net/ for details. 19.3. General notes when adding, updating, or removing packages Please note all package additions, updates, moves, and removals in pkgsrc/doc/ CHANGES. It's very important to keep this file up to date and conforming to the existing format, because it will be used by scripts to automatically update pages on www.NetBSD.org and other sites. Additionally, check the pkgsrc/doc/ TODO file and remove the entry for the package you updated or removed, in case it was mentioned there. When the PKGREVISION of a package is bumped, the change should appear in pkgsrc /doc/CHANGES if it is security related or otherwise relevant. Mass bumps that result from a dependency being updated should not be mentioned. In all other cases it's the developer's decision. There is a make target that helps in creating proper CHANGES entries: make changes-entry. It uses the optional CTYPE and NETBSD_LOGIN_NAME variables. The general usage is to first make sure that your CHANGES file is up-to-date (to avoid having to resolve conflicts later-on) and then to cd to the package directory. For package updates, make changes-entry is enough. For new packages, or package moves or removals, set the CTYPE variable on the command line to "Added", "Moved", or "Removed". You can set NETBSD_LOGIN_NAME in /etc/mk.conf if your local login name is not the same as your NetBSD login name. Don't forget to commit the changes to pkgsrc/doc/CHANGES! 19.4. Committing: Importing a package into CVS This section is only of interest for pkgsrc developers with write access to the pkgsrc repository. Please remember that cvs imports files relative to the current working directory, and that the pathname that you give the cvs import command is so that it knows where to place the files in the repository. Newly created packages should be imported with a vendor tag of "TNF" and a release tag of "pkgsrc-base", e.g: $ cd .../pkgsrc/category/pkgname $ cvs import pkgsrc/category/pkgname TNF pkgsrc-base Remember to move the directory from which you imported out of the way, or cvs will complain the next time you "cvs update" your source tree. Also don't forget to add the new package to the category's Makefile. The commit message of the initial import should include part of the DESCR file, so people reading the mailing lists know what the package is/does. For new packages, "cvs import" is preferred to "cvs add" because the former gets everything with a single command, and provides a consistent tag. 19.5. Updating a package to a newer version Please always put a concise, appropriate and relevant summary of the changes between old and new versions into the commit log when updating a package. There are various reasons for this: * A URL is volatile, and can change over time. It may go away completely or its information may be overwritten by newer information. * Having the change information between old and new versions in our CVS repository is very useful for people who use either cvs or anoncvs. * Having the change information between old and new versions in our CVS repository is very useful for people who read the pkgsrc-changes mailing list, so that they can make tactical decisions about when to upgrade the package. Please also recognize that, just because a new version of a package has been released, it should not automatically be upgraded in the CVS repository. We prefer to be conservative in the packages that are included in pkgsrc - development or beta packages are not really the best thing for most places in which pkgsrc is used. Please use your judgement about what should go into pkgsrc, and bear in mind that stability is to be preferred above new and possibly untested features. 19.6. Moving a package in pkgsrc 1. Make a copy of the directory somewhere else. 2. Remove all CVS dirs. Alternatively to the first two steps you can also do: % cvs -d user@cvs.NetBSD.org:/cvsroot export -D today pkgsrc/category/package and use that for further work. 3. Fix CATEGORIES and any DEPENDS paths that just did "../package" instead of "../../category/package". 4. cvs import the modified package in the new place. 5. Check if any package depends on it: % cd /usr/pkgsrc % grep /package */*/Makefile* */*/buildlink* 6. Fix paths in packages from step 5 to point to new location. 7. cvs rm (-f) the package at the old location. 8. Remove from oldcategory/Makefile. 9. Add to newcategory/Makefile. 10. Commit the changed and removed files: % cvs commit oldcategory/package oldcategory/Makefile newcategory/Makefile (and any packages from step 5, of course). Chapter 20. Frequently Asked Questions This section contains the answers to questions that may arise when you are writing a package. If you don't find your question answered here, first have a look in the other chapters, and if you still don't have the answer, ask on the pkgsrc-users mailing list. 20.1. What is the difference between MAKEFLAGS, .MAKEFLAGS and MAKE_FLAGS? 20.2. What is the difference between MAKE, GMAKE and MAKE_PROGRAM? 20.3. What is the difference between CC, PKG_CC and PKGSRC_COMPILER? 20.4. What is the difference between BUILDLINK_LDFLAGS, BUILDLINK_LDADD and BUILDLINK_LIBS? 20.5. Why does make show-var VARNAME=BUILDLINK_PREFIX.foo say it's empty? 20.6. What does ${MASTER_SITE_SOURCEFORGE:=package/} mean? I don't understand the := inside it. 20.7. Which mailing lists are there for package developers? 20.8. Where is the pkgsrc documentation? 20.1. What is the difference between MAKEFLAGS, .MAKEFLAGS and MAKE_FLAGS? MAKEFLAGS are the flags passed to the pkgsrc-internal invocations of make (1), while MAKE_FLAGS are the flags that are passed to the MAKE_PROGRAM when building the package. [FIXME: What is .MAKEFLAGS for?] 20.2. What is the difference between MAKE, GMAKE and MAKE_PROGRAM? MAKE is the path to the make(1) program that is used in the pkgsrc infrastructure. GMAKE is the path to GNU Make, but you need to say USE_TOOLS+=gmake to use that. MAKE_PROGRAM is the path to the Make program that is used for building the package. 20.3. What is the difference between CC, PKG_CC and PKGSRC_COMPILER? CC is the path to the real C compiler, which can be configured by the pkgsrc user. PKG_CC is the path to the compiler wrapper. PKGSRC_COMPILER is not a path to a compiler, but the type of compiler that should be used. See mk/compiler.mk for more information about the latter variable. 20.4. What is the difference between BUILDLINK_LDFLAGS, BUILDLINK_LDADD and BUILDLINK_LIBS? [FIXME] 20.5. Why does make show-var VARNAME=BUILDLINK_PREFIX.foo say it's empty? For optimization reasons, some variables are only available in the "wrapper" phase and later. To "simulate" the wrapper phase, append PKG_PHASE=wrapper to the above command. 20.6. What does ${MASTER_SITE_SOURCEFORGE:=package/} mean? I don't understand the := inside it. The := is not really an assignment operator, like you might expect at first sight. Instead, it is a degenerate form of ${LIST:old_string= new_string}, which is documented in the make(1) man page and which you may have seen as in ${SRCS:.c=.o}. In the case of MASTER_SITE_*, old_string is the empty string and new_string is package/. That's where the : and the = fall together. 20.7. Which mailing lists are there for package developers? tech-pkg This is a list for technical discussions related to pkgsrc development, e.g. soliciting feedback for changes to pkgsrc infrastructure, proposed new features, questions related to porting pkgsrc to a new platform, advice for maintaining a package, patches that affect many packages, help requests moved from pkgsrc-users when an infrastructure bug is found, etc. pkgsrc-bugs All bug reports in category "pkg" sent with send-pr(1) appear here. Please do not report your bugs here directly; use one of the other mailing lists. 20.8. Where is the pkgsrc documentation? There are many places where you can find documentation about pkgsrc: * The pkgsrc guide (this document) is a collection of chapters that explain large parts of pkgsrc, but some chapters tend to be outdated. Which ones they are is hard to say. * On the mailing list archives (see http://mail-index.NetBSD.org/), you can find discussions about certain features, announcements of new parts of the pkgsrc infrastructure and sometimes even announcements that a certain feature has been marked as obsolete. The benefit here is that each message has a date appended to it. * Many of the files in the mk/ directory start with a comment that describes the purpose of the file and how it can be used by the pkgsrc user and package authors. * The CVS log messages are a rich source of information, but they tend to be highly abbreviated, especially for actions that occur often. Some contain a detailed description of what has changed, but they are geared towards the other pkgsrc developers, not towards an average pkgsrc user. They also only document changes, so if you don't know what has been before, these messages may not be worth too much to you. * Some parts of pkgsrc are only "implicitly documented", that is the documentation exists only in the mind of the developer who wrote the code. To get this information, use the the cvs annotate command to see who has written it and ask on the tech-pkg mailing list, so that others can find your questions later (see above). To be sure that the developer in charge reads the mail, you may CC him or her. Part III. The pkgsrc infrastructure internals This part of the guide deals with everything from the infrastructure that is behind the interfaces described in the developer's guide.

The order in bsd.prefs.mk 21.6.2. The order in bsd.pkg.mk The pkgsrc infrastructure consists of many small Makefile fragments. Each such fragment needs a properly specified interface. This chapter explains how such an interface looks like. 21.1. The meaning of variable definitions Whenever a variable is defined in the pkgsrc infrastructure, the location and the way of definition provide much information about the intended use of that variable. Additionally, more documentation may be found in a header comment or in this pkgsrc guide. A special file is mk/defaults/mk.conf, which lists all variables that are intended to be user-defined. They are either defined using the ?= operator or they are left undefined because defining them to anything would effectively mean "yes". All these variables may be overridden by the pkgsrc user in the MAKECONF file. Outside this file, the following conventions apply: Variables that are defined using the ?= operator may be overridden by a package. Variables that are defined using the = operator may be used read-only at run-time. Variables whose name starts with an underscore must not be accessed outside the pkgsrc infrastructure at all. They may change without further notice. Note These conventions are currently not applied consistently to the complete pkgsrc infrastructure. 21.2. Avoiding problems before they arise All variables that contain lists of things should default to being empty. Two examples that do not follow this rule are USE_LANGUAGES and DISTFILES. These variables cannot simply be modified using the += operator in package Makefiles (or other files included by them), since there is no guarantee whether the variable is already set or not, and what its value is. In the case of DISTFILES, the packages "know" the default value and just define it as in the following example. DISTFILES= ${DISTNAME}${EXTRACT_SUFX} additional-files.tar.gz Because of the selection of this default value, the same value appears in many package Makefiles. Similarly for USE_LANGUAGES, but in this case the default value ("c") is so short that it doesn't stand out. Nevertheless it is mentioned in many files. 21.3. Variable evaluation 21.3.1. At load time Variable evaluation takes place either at load time or at runtime, depending on the context in which they occur. The contexts where variables are evaluated at load time are: * The right hand side of the := and != operators, * Make directives like .if or .for, * Dependency lines. A special exception are references to the iteration variables of .for loops, which are expanded inline, no matter in which context they appear. As the values of variables may change during load time, care must be taken not to evaluate them by accident. Typical examples for variables that should not be evaluated at load time are DEPENDS and CONFIGURE_ARGS. To make the effect more clear, here is an example: CONFIGURE_ARGS= # none CFLAGS= -O CONFIGURE_ARGS+= CFLAGS=${CFLAGS:Q} CONFIGURE_ARGS:= ${CONFIGURE_ARGS} CFLAGS+= -Wall This code shows how the use of the := operator can quickly lead to unexpected results. The first paragraph is fairly common code. The second paragraph evaluates the CONFIGURE_ARGS variable, which results in CFLAGS=-O. In the third paragraph, the -Wall is appended to the CFLAGS, but this addition will not appear in CONFIGURE_ARGS. In actual code, the three paragraphs from above typically occur in completely unrelated files. 21.3.2. At runtime After all the files have been loaded, the values of the variables cannot be changed anymore. Variables that are used in the shell commands are expanded at this point. 21.4. How can variables be specified? There are many ways in which the definition and use of a variable can be restricted in order to detect bugs and violations of the (mostly unwritten) policies. See the pkglint developer's documentation for further details. 21.5. Designing interfaces for Makefile fragments Most of the .mk files fall into one of the following classes. Cases where a file falls into more than one class should be avoided as it often leads to subtle bugs. 21.5.1. Procedures with parameters In a traditional imperative programming language some of the .mk files could be described as procedures. They take some input parameters and?after inclusion? provide a result in output parameters. Since all variables in Makefiles have global scope care must be taken not to use parameter names that have already another meaning. For example, PKGNAME is a bad choice for a parameter name. Procedures are completely evaluated at preprocessing time. That is, when calling a procedure all input parameters must be completely resolvable. For example, CONFIGURE_ARGS should never be an input parameter since it is very likely that further text will be added after calling the procedure, which would effectively apply the procedure to only a part of the variable. Also, references to other variables wit will be modified after calling the procedure. A procedure can declare its output parameters either as suitable for use in preprocessing directives or as only available at runtime. The latter alternative is for variables that contain references to other runtime variables. Procedures shall be written such that it is possible to call the procedure more than once. That is, the file must not contain multiple-inclusion guards. Examples for procedures are mk/bsd.options.mk and mk/buildlink3/bsd.builtin.mk. To express that the parameters are evaluated at load time, they should be assigned using the := operator, which should be used only for this purpose. 21.5.2. Actions taken on behalf of parameters Action files take some input parameters and may define runtime variables. They shall not define loadtime variables. There are action files that are included implicitly by the pkgsrc infrastructure, while other must be included explicitly. An example for action files is mk/subst.mk. 21.6. The order in which files are loaded Package Makefiles usually consist of a set of variable definitions, and include the file ../../mk/bsd.pkg.mk in the very last line. Before that, they may also include various other *.mk files if they need to query the availability of certain features like the type of compiler or the X11 implementation. Due to the heavy use of preprocessor directives like .if and .for, the order in which the files are loaded matters. This section describes at which point the various files are loaded and gives reasons for that order. 21.6.1. The order in bsd.prefs.mk The very first action in bsd.pkg.mk is to define some essential variables like OPSYS, OS_VERSION and MACHINE_ARCH. Then, the user settings are loaded from the file specified in MAKECONF. If the bmake command from pkgsrc is used, MAKECONF defaults to ${prefix}/etc/mk.conf. With the native make(1) command on NetBSD, it defaults to /etc/mk.conf. After that, those variables that have not been overridden by the user are loaded from mk/defaults/mk.conf. After the user settings, the system settings and platform settings are loaded, which may override the user settings. Then, the tool definitions are loaded. The tool wrappers are not yet in effect. This only happens when building a package, so the proper variables must be used instead of the direct tool names. As the last steps, some essential variables from the wrapper and the package system flavor are loaded, as well as the variables that have been cached in earlier phases of a package build. 21.6.2. The order in bsd.pkg.mk First, bsd.prefs.mk is loaded. Then, the various *-vars.mk files are loaded, which fill default values for those variables that have not been defined by the the package. These variables may later be used even in unrelated files. Then, the file bsd.pkg.error.mk provides the target error-check that is added as a special dependency to all other targets that use DELAYED_ERROR_MSG or DELAYED_WARNING_MSG. Then, the package-specific hacks from hacks.mk are included. Then, various other files follow. Most of them don't have any dependencies on what they need to have included before or after them, though some do. The code to check PKG_FAIL_REASON and PKG_SKIP_REASON is then executed, which restricts the use of these variables to all the files that have been included before. Appearances in later files will be silently ignored. Then, the files for the main targets are included, in the order of later execution, though the actual order should not matter. At last, some more files are included that don't set any interesting variables but rather just define make targets to be executed. Chapter 22. Regression tests Table of Contents 22.1. The regression tests framework 22.2. Running the regression tests 22.3. Adding a new regression test 22.3.1. Overridable functions 22.3.2. Helper functions The pkgsrc infrastructure consists of a large codebase, and there are many corners where every little bit of a file is well thought out, making pkgsrc likely to fail as soon as anything is changed near those parts. To prevent most changes from breaking anything, a suite of regression tests should go along with every important part of the pkgsrc infrastructure. This chapter describes how regression tests work in pkgsrc and how you can add new tests. 22.1. The regression tests framework 22.2. Running the regression tests You first need to install the pkgtools/pkg_regress package, which provides the pkg_regress command. Then you can simply run that command, which will run all tests in the regress category. 22.3. Adding a new regression test Every directory in the regress category that contains a file called spec is considered a regression test. This file is a shell program that is included by the pkg_regress command. The following functions can be overridden to suit your needs. 22.3.1. Overridable functions These functions do not take any parameters. They are all called in "set -e" mode, so you should be careful to check the exitcodes of any commands you run in the test. do_setup() This function prepares the environment for the test. By default it does nothing. do_test() This function runs the actual test. By default, it calls TEST_MAKE with the arguments MAKEARGS_TEST and writes its output including error messages into the file TEST_OUTFILE. check_result() This function is run after the test and is typically used to compare the actual output from the one that is expected. It can make use of the various helper functions from the next section. do_cleanup() This function cleans everything up after the test has been run. By default it does nothing. 22.3.2. Helper functions exit_status(expected) This function compares the exitcode of the do_test() function with its first parameter. If they differ, the test will fail. output_require(regex...) This function checks for each of its parameters if the output from do_test () matches the extended regular expression. If it does not, the test will fail. output_prohibit(regex...) This function checks for each of its parameters if the output from do_test () does not match the extended regular expression. If any of the regular expressions matches, the test will fail. Chapter 23. Porting pkgsrc Table of Contents 23.1. Porting pkgsrc to a new operating system 23.2. Adding support for a new compiler The pkgsrc system has already been ported to many operating systems, hardware architectures and compilers. This chapter explains the necessary steps to make pkgsrc even more portable. 23.1. Porting pkgsrc to a new operating system To port pkgsrc to a new operating system (called MyOS in this example), you need to touch the following files: bootstrap/mods/mk/MyOS.sys.mk This file contains some basic definitions, for example the name of the C compiler. mk/bsd.prefs.mk Insert code that defines the variables OPSYS, OS_VERSION, LOWER_OS_VERSION, LOWER_VENDOR, MACHINE_ARCH, OBJECT_FMT, APPEND_ELF, and the other variables that appear in this file. mk/platform/MyOS.mk This file contains the platform-specific definitions that are used by pkgsrc. Start by copying one of the other files and edit it to your needs. mk/platform/MyOS.pkg.dist This file contains a list of directories, together with their permission bits and ownership. These directories will be created automatically with every package that does not explicitly set NO_MTREE. There have been some discussions about whether this file is needed at all, but with no result. mk/platform/MyOS.x11.dist Just copy one of the pre-existing x11.dist files to your MyOS.x11.dist. mk/tools/bootstrap.mk On some operating systems, the tools that are provided with the base system are not good enough for pkgsrc. For example, there are many versions of sed (1) that have a narrow limit on the line length they can process. Therefore pkgsrc brings its own tools, which can be enabled here. mk/tools/MyOS.mk This file defines the paths to all the tools that are needed by one or the other package in pkgsrc, as well as by pkgsrc itself. Find out where these tools are on your platform and add them. Now, you should be able to build some basic packages, like lang/perl5, shells/ bash. 23.2. Adding support for a new compiler TODO Appendix A. A simple example package: bison Table of Contents A.1. files A.1.1. Makefile A.1.2. DESCR A.1.3. PLIST A.1.4. Checking a package with pkglint A.2. Steps for building, installing, packaging We checked to find a piece of software that wasn't in the packages collection, and picked GNU bison. Quite why someone would want to have bison when Berkeley yacc is already present in the tree is beyond us, but it's useful for the purposes of this exercise. A.1. files A.1.1. Makefile # $NetBSD$ # DISTNAME= bison-1.25 CATEGORIES= devel MASTER_SITES= ${MASTER_SITE_GNU} MAINTAINER= thorpej@NetBSD.org HOMEPAGE= http://www.gnu.org/software/bison/bison.html COMMENT= GNU yacc clone GNU_CONFIGURE= yes INFO_FILES= bison.info .include "../../mk/bsd.pkg.mk" A.1.2. DESCR GNU version of yacc. Can make re-entrant parsers, and numerous other improvements. Why you would want this when Berkeley yacc(1) is part of the NetBSD source tree is beyond me. A.1.3. PLIST @comment $NetBSD$ bin/bison man/man1/bison.1.gz share/bison.simple share/bison.hairy A.1.4. Checking a package with pkglint The NetBSD package system comes with pkgtools/pkglint which helps to check the contents of these files. After installation it is quite easy to use, just change to the directory of the package you wish to examine and execute pkglint: $ pkglint looks fine. Depending on the supplied command line arguments (see pkglint(1)), more checks will be performed. Use e.g. pkglint -Call -Wall for a very thorough check. A.2. Steps for building, installing, packaging Create the directory where the package lives, plus any auxiliary directories: # cd /usr/pkgsrc/lang # mkdir bison # cd bison # mkdir patches Create Makefile, DESCR and PLIST (see Chapter 9, Package components - files, directories and contents) then continue with fetching the distfile: # make fetch >> bison-1.25.tar.gz doesn't seem to exist on this system. >> Attempting to fetch from ftp://prep.ai.mit.edu/pub/gnu//.

Directory layout of the pkgsrc FTP server Table of Contents C.1. bootstrap-pkgsrc: Bootstrap kits C.2. distfiles: The distributed source files C.3. iso: Currently empty C.4. misc: Miscellaneous things C.5. packages*: Binary packages C.6. current, 200xQy: source packages As in other big projects, the directory layout of pkgsrc is quite complex for newbies. This chapter explains where you find things on the FTP server. The base directory on ftp.NetBSD.org is /pub/pkgsrc. This directory contains some subdirectories, which are explained below. C.1. bootstrap-pkgsrc: Bootstrap kits For those who only want to manage binary packages on systems other than NetBSD, we provide the package management tools in a separate, small tar file. C.2. distfiles: The distributed source files The directory distfiles contains lots of archive files from all pkgsrc packages, which are mirrored here. The subdirectories are called after their package names and are used when the distributed files have names that don't explicitly contain a version number or are otherwise too generic (for example release.tar.gz). C.3. iso: Currently empty This directory is currently not in use. C.4. misc: Miscellaneous things This directory contains things that individual pkgsrc developers find worth publishing. C.5. packages*: Binary packages These directories contain binary packages. Those directories that have a branch name (200xQy) contain packages from that particular branch. The directory packages contains binary packages from pkgsrc-current. (However, this does not necessarily mean that the packages are still current anymore.) Below the packages* directories are directories that distinguish the packages by operating system and version, the next directory level specifies the hardware architecture. In each of the platform-specific directories, there is a whole binary packages collection. It has a directory called All which contains all binary packages. Besides that, there are various category directories that contain symbolic links to the real binary packages. C.6. current, 200xQy: source packages These directories contain the "real" pkgsrc, that is the files that define how to create binary packages from source archives. The directory pkgsrc contains a snapshot of the CVS repository, which is updated on a regularly basis. The file pkgsrc.tar.gz contains the same as the directory, ready to be downloaded as a whole. In the directories for the quarterly branches, there is an additional file called pkgsrc-200xQy.tar.gz, which contains the state of pkgsrc when it was branched. Appendix D. Editing guidelines for the pkgsrc guide Table of Contents D.1. Make targets D.2. Procedure This section contains information on editing the pkgsrc guide itself. D.1. Make targets The pkgsrc guide's source code is stored in pkgsrc/doc/guide/files, and several files are created from it: * pkgsrc/doc/pkgsrc.txt * pkgsrc/doc/pkgsrc.html * http://www.NetBSD.org/Documentation/pkgsrc/ * http://www.NetBSD.org/Documentation/pkgsrc/pkgsrc.pdf: The PDF version of the pkgsrc guide. * http://www.NetBSD.org/Documentation/pkgsrc/pkgsrc.ps: PostScript version of the pkgsrc guide. D.2. Procedure The procedure to edit the pkgsrc guide is: 1. Make sure you have the packages needed to regenerate the pkgsrc guide (and other XML-based NetBSD documentation) installed. These are meta-pkgs/ netbsd-doc for creating the ASCII and HTML versions, and meta-pkgs/ netbsd-doc-print for the PostScript and PDF versions. You will need both packages installed, to make sure documentation is consistent across all formats. 2. Run cd doc/guide to get to the right directory. All further steps will take place here. 3. Edit the XML file(s) in files/. 4. Run bmake to check the pkgsrc guide for valid XML and to build the final output files. If you get any errors at this stage, you can just edit the files, as there are only symbolic links in the working directory, pointing to the files in files/. 5. (cd files && cvs commit) 6. Run bmake clean && bmake to regenerate the output files with the proper RCS Ids. 7. Run bmake regenerate to regenerate the files in both pkgsrc/doc and htdocs. 8. If you have added, removed or renamed some chapters, you need to synchronize them using cvs add or cvs delete in the htdocs directory.
