It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change.

opt.delscn.c: new file. + @@ -0,0 +1,176 @@ +Basic Installation +================== + + These are generic installation instructions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, a file +`config.cache' that saves the results of its tests to speed up +reconfiguring, and a file `config.log' containing compiler output +(useful mainly for debugging `configure'). + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If at some point `config.cache' +contains results you don't want to keep, you may remove or edit it. + + The file `configure.in' is used to create `configure' by a program +called `autoconf'. You only need `configure.in' if you want to change +it or regenerate `configure' using a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. You can give `configure' +initial values for variables by setting them in the environment. Using +a Bourne-compatible shell, you can do that on the command line like +this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + +Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not supports the `VPATH' +variable, you have to compile the package for one architecture at a time +in the source code directory. After you have installed the package for +one architecture, use `make distclean' before reconfiguring for another +architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' can not figure out +automatically, but needs to determine by the type of host the package +will run on. Usually `configure' can figure that out, but if it prints +a message saying it can not guess the host type, give it the +`--host=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name with three fields: + CPU-COMPANY-SYSTEM + +See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the host type. + + If you are building compiler tools for cross-compiling, you can also +use the `--target=TYPE' option to select the type of system they will +produce code for and the `--build=TYPE' option to select the type of +system on which you are compiling the package. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Operation Controls +================== + + `configure' recognizes the following options to control how it +operates. + +`--cache-file=FILE' + Use and save the results of the tests in FILE instead of + `./config.cache'. Set FILE to `/dev/null' to disable caching, for + debugging `configure'. + +`--help' + Print a summary of the options to `configure', and exit. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`--version' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`configure' also accepts some other, not widely useful, options. + diff --git a/MANIFEST b/MANIFEST new file mode 100644 index 0000000..4ced37c --- /dev/null +++ b/MANIFEST @@ -0,0 +1,96 @@ +25275 COPYING.LIB +35406 ChangeLog +7462 INSTALL +5908 Makefile.in +13232 README +7 VERSION +2955 acconfig.h +9381 aclocal.m4 +43611 config.guess +3987 config.h.in +31160 config.sub +110753 configure +11736 configure.in +2186 install-sh +4798 lib/32.fsize.c +1556 lib/32.getehdr.c +1557 lib/32.getphdr.c +1665 lib/32.getshdr.c +2181 lib/32.newehdr.c +3055 lib/32.newphdr.c +12322 lib/32.xlatetof.c +14221 lib/64.xlatetof.c +8012 lib/Makefile.in +4010 lib/Makefile.w32 +1119 lib/assert.c +10463 lib/begin.c +1685 lib/build.bat +3566 lib/byteswap.h +3937 lib/checksum.c +1901 lib/cntl.c +4851 lib/config.h.w32 +12554 lib/cook.c +1183 lib/data.c +24585 lib/elf_repl.h +2899 lib/end.c +2137 lib/errmsg.c +1037 lib/errno.c +6222 lib/errors.h +8107 lib/ext_types.h +997 lib/fill.c +2400 lib/flag.c +5103 lib/gelf.h +4151 lib/gelfehdr.c +3965 lib/gelfphdr.c +3758 lib/gelfshdr.c +9456 lib/gelftrans.c +1175 lib/getarhdr.c +1380 lib/getaroff.c +2421 lib/getarsym.c +1096 lib/getbase.c +3841 lib/getdata.c +1353 lib/getident.c +1449 lib/getscn.c +1212 lib/hash.c +2562 lib/input.c +1088 lib/kind.c +1214 lib/libelf.def +9050 lib/libelf.h +1505 lib/memset.c +1098 lib/ndxscn.c +1558 lib/newdata.c +3488 lib/newscn.c +1356 lib/next.c +1607 lib/nextscn.c +5898 lib/nlist.c +1452 lib/nlist.h +5071 lib/opt.delscn.c +13133 lib/private.h +1286 lib/rand.c +2543 lib/rawdata.c +1541 lib/rawfile.c +3393 lib/strptr.c +2285 lib/swap64.c +3812 lib/sys_elf.h.in +4066 lib/sys_elf.h.w32 +26008 lib/update.c +6884 lib/verdef.h +1586 lib/verdef_32_tof.c +1586 lib/verdef_32_tom.c +1614 lib/verdef_64_tof.c +1614 lib/verdef_64_tom.c +7135 lib/verneed.h +1435 lib/version.c +4425 lib/x.elfext.c +2721 lib/x.movscn.c +2870 lib/x.remscn.c +254 libelf.pc.in +619 mkinstalldirs +4593 po/Makefile.in +8748 po/de.gmo +52 po/de.msg +11332 po/de.po +3011 po/gmo2msg.c +6483 po/libelf.pot +10 po/stamp-po +10 stamp-h.in diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..3f38307 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,198 @@ +# Makefile for libelf. +# Copyright (C) 1995 - 2005 Michael Riepe +# +# This library is free software; you can redistribute it and/or +# modify it under the terms of the GNU Library General Public +# License as published by the Free Software Foundation; either +# version 2 of the License, or (at your option) any later version. +# +# This library is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If you have problems with applications +that use libelf and work with the commercial (SVR4, Solaris) +version but not with this one, please contact me. + +IMPORTANT NOTE: If you have libelf-0.5.2 installed, you probably +have a file .../include/elf.h that contains the single line +``#include <libelf/elf.h>''. REMOVE THIS FILE BEFORE YOU RUN +configure. + +Installation is straightforward - the package is autoconf'ed. Just do +``cd libelf-0.8.13; ./configure; make; make install''. Header files +will be installed in .../include/libelf/. If your system does not +provide its own versions of libelf.h, nlist.h or gelf.h, ``make +install'' will add the missing headers. If you prefer not to have +these files installed in /usr/include, use ``--disable-compat'' and +add ``-I /usr/include/libelf'' to your CFLAGS when compiling +libelf-based programs. + +Note to distribution makers: You can install libelf in a separate root +hierarchy by using the command ``make instroot=/my/root install''. +You should also use the ``--enable-compat'' configure option in that +case, or run ``make instroot=/my/root install-compat'' manually, to +install all the required header files. + +If you are running Linux with libc 5.* as the default C library, +and you plan to use the 64-bit functions, you must either use +``-I.../include/libelf'', or remove /usr/include/libelf.h and use +``--enable-compat'' when running configure. Libc 6.* (aka glibc2) +doesn't have its own <libelf.h>, <nlist.h> or <gelf.h>. + +You need an ANSI/ISO C compiler to build libelf. Gcc is optimal. + +On some systems (in particular, Solaris and all variants of Linux), +``make'' will try to build a shared library. If you run into problems +on your system, please pass ``--disable-shared'' to configure. +If you build a shared library and want it to be installed as +``libelf-0.8.13.so'' rather than ``libelf.so.0.8.13'', please use +``./configure --enable-gnu-names''. Other files, e.g. ``libelf.so'' and +``libelf.so.0'' are NOT affected. + +Another configure option, ``--enable-debug'', adds debugging code to +libelf; if you don't run into problems, you will probably not need it. + +When creating an ELF shared library, it is possible to add references +to other shared libraries in the DYNAMIC section of the resulting +file. The make variable DEPSHLIBS contains a list of libraries to add. +It is set to ``-lc'' on Linux systems, and empty otherwise. To +override this setting, use something like ``make DEPSHLIBS="-la -lb"''. +For Linux, `-lc' is included automagically. + +NLS is available and enabled by default. To turn it off, pass the +``--disable-nls'' option to configure. + +Libelf can use gettext or catgets for accessing message +catalogs. If gettext is available AND is part of libc (i.e. not +in a separate library), it will be used. Otherwise, configure +will look for catgets. If you have gettext in a separate +library and want to use it, you should pass the library's name +to configure, e.g. ``LIBS=-lintl ./configure''. Note that you +MUST link your libelf-based applications with -lintl then, +which is probably not what you want, or change the DEPSHLIBS variable +described above (in case you're building a shared library). + +If you have GNU gettext 0.10 installed on your system, and if GNU gettext +runs on top of the catgets interface (rather old Linux systems, using +libc5), configure will refuse to use it and use catgets instead. If you +absolutely want to use GNU gettext, go ahead and rebuild it (which is +IMHO a good idea in general in this case): + + cd .../gettext-0.10 + ac_cv_func_catgets=no ac_cv_func_gettext=no ./configure + make + make install + +After that, return to the libelf build directory, remove +config.cache, and start over. + +*** Large File Support (LFS) applications *** + +Some 32-bit systems support files that are larger than the address space +of the architecture. On these, the `off_t' data type may have 32 or +64 bits, depending on the API you choose. Since off_t is also part of +the libelf API, in particular the Elf_Data and Elf_Arhdr structures, +an application compiled with large file support will need a version of +libelf that has also been compiled with LFS; otherwise, it won't work +correctly. Similarly, a program compiled without LFS needs a library +compiled without LFS. + +Note that libelf is currently unable to process large files on 32-bit +architectures, whether you compile it for LFS or not, for the simple +reason that the files won't fit into the processes' address space. +Therefore, libelf is compiled without LFS by default. It can of course +read and write ELF files for 64-bit architectures, but they will be +limited in length on a 32-bit system. + +You may compile libelf with large file support by setting CPPFLAGS at +configuration time: + + CPPFLAGS=`getconf LFS_CFLAGS` ./configure + +But I really, really recommend you don't, because it breaks binary +compatibility with existing libelf based applications. + +*** 64-bit support *** + +Starting with libelf-0.7.0, libelf also supports 64-bit ELF files. +This is enabled by default unless your system (or your compiler) does +not support 64-bit integers, or lacks 64-bit declarations in <elf.h>. +If you have problems building with 64-bit support, please do + + ./configure --disable-elf64 + +for the moment, and contact me. Please note that I haven't tested 64-bit +support much. There are still some unresolved problems, e.g. IRIX +uses different Elf64_Rel and Elf64_Rela structures (they replaced the +r_info member), and the enumeration values for Elf_Type differ from +the commercial (SVR4) implementation of libelf - they broke binary +compatibility for no good reason, and I'm not willing to follow their +footsteps. The result is that libelf-0.7.* ist upward compatible with +libelf-0.6.4 (as it should be) but INCOMPATIBLE WITH SVR4 LIBELF. If you +have both versions installed, you'd better make sure that you link with +the library that matches the <libelf.h> you're #include'ing. + +*** Symbol Versioning *** + +Libelf >= 0.8.0 supports the data structures and definitions used for +symbol versioning on Solaris and Linux, in particular, the Elfxx_Verdef, +Elfxx_Verdaux, Elfxx_Verneed, Elfxx_Vernaux and Elfxx_Versym structures +and the SHT_XXX_verdef, SHT_XXX_verneed and SHT_XXX_versym section types +(where `xx' is either `32' or `64', and `XXX' is either `SUNW' or `GNU'). +Libelf now translates versioning sections to/from their external +representation properly (earlier versions left them in `raw' format, +with the data type set to ELF_T_BYTE). This may cause problems on +systems which use the same (OS-specific) section types for different +purposes. The configure program tries to figure out if your OS uses +versioning; if that check fails, you can use + + ./configure --disable-versioning + +to turn off versioning translation support. + +*** W32 Support *** + +There is now some support for building on W32 systems (requires Microsoft +VC++). In order to build a W32 DLL, cd into the `lib' subdirectory, edit +build.bat if necessary (it needs the path to your compiler binaries) and +run it. If you're lucky, libelf.dll and the import/export libraries will +be built. If not, please drop me a line. + +I tested it on XP Pro (SP2), using VC++ 2005 Express Edition. +Apparently, Visual Studio .NET 2003 works fine as well. + +Various notes regarding the W32 port: + + - When you open() an ELF file, remember to use the O_BINARY flag. + - You may have to add /MD to the linker command line. + +*** Missing things *** + + * There is no documentation. You can use the Solaris + manpages instead (available at http://docs.sun.com/). + The ELF file format is described in several places; + among them Suns "Linker and Libraries Guide" and the + "System V Application Binary Interface" documents; + http://www.caldera.com/developer/devspecs/gabi41.pdf and + http://www.caldera.com/developer/gabi/ are probably good + starting points. Processor-specific documentation is spread + across a number of `Processor Supplement' documents, one + for each architecture; you'll have to use a search engine to + find them. + + * The COFF file format is not understood. This is so obsolete + that it will probably never be implemented. + + * nlist(3) is incomplete; the n_type and n_sclass + members of struct nl are set to zero even if type + (that is, debug) information is available. + + * Libelf does not translate Solaris' `Move' and `Syminfo' + sections. You can read them using elf_getdata(), but you'll + only get raw (untranslated) bytes. + +Changes since 0.8.12: + + * New function elf_getaroff(). + + * Build fixes. + +Changes since 0.8.11: + + * Due to some unfortunate confusion, the elf_getphnum(), + elf_getshnum() and elf_getshstrndx() are not compatible + between libelf implementations. Therefore, the developers + decided to replace them with new functions: elf_getphdrnum(), + elf_getshdrnum() and elf_getshdrstrndx(), which will always + return -1 on failure and 0 on success. Code using the old + interface should be upgraded to increase portability. + +Changes since 0.8.10: + + * Fixed a bug in elf_rawfile(). + * If you use ELF_F_LAYOUT together with ELF_F_LAYOUT_OVERLAP, + elf_update() will now tolerate overlapping sections. + +Changes since 0.8.9: + + * Ported to QNX Neutrino. + * Fixed Windows build errors. + * Parallel (make -j) installation should work now. + + * It's now possible to enable and disable select sanity checks + libelf performs. Currently, this affects the "NUL terminated + string table entry" check performed in elf_strptr(). By + default, the function will return an error if the string + requested is not properly terminated - because some + applications might dump core otherwise. If you configure + libelf with `--disable-sanity-checks', however, the check + (and, in the future, probably others as well) is disabled + by default. You can still turn it on and off at runtime by + setting the LIBELF_SANITY_CHECKS environment variable to + an integer value: + + # disable all sanity checks + export LIBELF_SANITY_CHECKS=0 + + # enable all sanity checks + export LIBELF_SANITY_CHECKS=-1 + + Each bit of the value corresponds to a particular check, + so you could use LIBELF_SANITY_CHECKS=1 to enable only + the elf_strptr() check. You may also use a value in hex + (0x...) or octal (0...) format. + +Changes since 0.8.8: + + * Improved translator for symbol versioning sections. + * The W32 library is now built in the `lib' subdirectory. + * Windows DLLs should work now. + +Changes since 0.8.6: + + * added elf_getphnum(). + * added elf_getshnum(). + * added elf_getshstrndx(). + * added elfx_update_shstrndx(). + * handle interrupted reads/writes more gracefully. + * added (partial) support for unusual e_[ps]hentsize values. + * fixed the bugs introduced in 0.8.7. + +Changes since 0.8.5: + + * added W32 support. + * added workaround for alignment errors in archive members. + * my email address has changed again ;) + +Changes since 0.8.4: + + * elf_strptr() should now work more safely with fragmented + or badly formatted string tables. + +Changes since 0.8.3: + + * Fixed a bug in elf_update() that was introduced in 0.8.3. + +Changes since 0.8.2: + + * Should compile on MacOSX now. + + * Can read and write files with more than 65280 sections + + * Tries to handle 64-bit ELF files that use 8-byte hash table + entries. In particular, libelf tries to guess the data type in + elf_getdata(), and doesn't override sh_entsize in elf_update() + any longer. If you want the library to pick the entry size, + you must set its value to 0 before you call elf_update(). + + * No longer dumps core in elf_update() when a versioning section + has no data. Instead, it returns an error message.
