Content of source package
=========================
"openjdk-8" is a composite source package:
- Multiple tarballs from each Oracle mercurial repositories :
corba / hotspot / jaxp / jaxws / jdk-dfsg / langtools / openjdk
- Tarball from JamVM <http://jamvm.sourceforge.net>.
- Debian packaging scripts and patches.
Building a new OpenJDK-8 Debian package
===================================================
Pre-requisites:
- Mercurial
- Bazaar
sudo aptitude install mercurial bzr
0) Clone OpenJDK debian packaging:
bzr branch lp:~openjdk/openjdk/openjdk7 openjdk7/
or update existing repository clone:
(cd openjdk7/; bzr pull --remember lp:~openjdk/openjdk/openjdk7)
1) Clone IcedTea-7 HG:
hg clone http://icedtea.classpath.org/hg/icedtea7 icedtea-2.1.1/
or update existing repository clone:
(cd icedtea7/; hg pull -u)
2) Download OpenJDK upstream tarballs and move them to $BUILD/
export BUILD=7u3
mkdir -p $BUILD/
(
cd icedtea-2.1.1/
sh autogen.sh && ./configure --enable-jamvm
make download
)
mv icedtea-2.1.1/*.tar.gz $BUILD/
(
cd icedtea-2.1.1/
make distclean
)
3) Remove files with unclear license from jdk.tar.gz:
sh openjdk7/generate-dfsg-zip.sh $BUILD/jdk.tar.gz
sh openjdk7/generate-dfsg-zip.sh $BUILD/langtools.tar.gz
4) Check tarballs' name and version (for original directory name)
in openjdk7/generate-debian-orig.sh and package version in
openjdk7/changelog
5) Generate "orig" directory and "orig+debian" directory
sh openjdk7/generate-debian-orig.sh
Support for DEB_BUILD_OPTIONS
=============================
As described in Debian Policy §4.9.1, current package's debian/rules support
the standardized environment variable DEB_BUILD_OPTIONS. This variable can
contain several flags to change how a package is compiled and built.
* nocheck: don't run jtreg test suites.
* nodocs: pass --disable-docs to IcedTea configure script, which
disable Javadoc generation.
* nostrip: debugging symbols should not be stripped from the
binary during installation
* parallel=X: package should be built using up to X parallel processes
* nobootstrap: don't use gcj to bootstrap OpenJDK but use existing OpenJDK
installed on current machine.
* noaltzero: don't build alternative Zero VM.
* noaltshark: don't build alternative Shark VM.
* noaltjamvm: don't build alternative Jamvm VM.
Sample usage:
DEB_BUILD_OPTIONS="parallel=5 nocheck" debuild -i"(\.hg|\.bzr)"
Build with 5 parallel processes and don't run jtreg test suites.
This also work with cowbuilder/pbuilder:
DEB_BUILD_OPTIONS="parallel=5 nocheck" pdebuild -i"(\.hg|\.bzr)" --logfile ../build.log --pbuilder cowbuilder
