Instructions for compiling a toolchain:

  • ARCH = architecture (arm, i386, etc...)
  • Install apt-cross, dpkg-cross, autoconf, automake, gawk, flex, bison, debhelper, devscripts, cdbs, fakeroot
  • Run 'apt-cross -a $ARCH linux-kernel-headers libc6 libc6-dev'
  • 'apt-get source' binutils and gcc-4.1
  • cd binutils and run:
    • TARGET=$ARCH-linux-gnu fakeroot debian/rules binary-cross
  • Install resulting cross binutils
  • 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
  • Install resulting cross gcc-4.1

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 natural-flavours and run 'rrr includedeb etch deb-files...'.

If you need i386 binary libraries, you can run 'apt-cross -a i386 -i package'.
