Builder is a vserver that is used to build cross-compilers and cross-packages that that have --host=amd64. The current list of installed cross-compilers includes alpha, arm, hppa (binutils only), i486, ia64, m68k, mips, mipsel, powerpc, sparc and x86_64. www.emdebian.org builds a number of cross-compilers, which can be installed by adding the following lines to /etc/apt/sources.list:
deb http://mirror.csclub.uwaterloo.ca/emdebian/ stable main deb-src http://mirror.csclub.uwaterloo.ca/emdebian/ stable main
Compiling a toolchain
- export ARCH=architecture (arm, i386, etc...)
- sudo apt-get install apt-cross dpkg-cross autoconf automake gawk flex bison debhelper devscripts cdbs fakeroot
- apt-cross -a $ARCH -i linux-kernel-headers libc6 libc6-dev
- apt-get source binutils gcc-4.1
- cd binutils and run:
- TARGET=$ARCH-linux-gnu fakeroot debian/rules binary-cross
- sudo dpkg -i binutils-$ARCH-linux-gnu_*.deb
- cd gcc-4.1 and run:
- export GCC_TARGET=$ARCH
- export DEB_CROSS_INDEPENDENT=yes
- export WITHOUT_LANG=java,fortran,pascal,obj,obj-c++,ada,treelang
- export DEB_CROSS_NO_BIARCH=yes
- debian/rules control
- dpkg-buildpackage -b -rfakeroot
- sudo dpkg -i gcc-4.1-*.deb
It's generally useful to upload these built packages to the CSC debian repository. To do this you need to scp the .deb's over to debian.csclub and run 'rrr-includedeb deb-files...'.
Emdebian
Emdebian is the Debian project responsible for dpkg-cross, apt-cross, and emdebian-tools.
Dpkg-cross
Dpkg-cross is a version of dpkg that allows you to install architecture-specific libraries in an isolated way. For example, dpkg-cross will build a package called libc6-mips-cross from the mips libc6 package. This cross package can then be installed alongside the mips cross-compiler.
Apt-cross
Apt-cross is a front-end to dpkg-cross. It will automatically fetch and build cross packages.
Emdebuild
Emdebuild is an architecture aware version of debuild.
