Debian cross-gcc snapshot packages


This is an APT repository that provides unofficial snapshot Debian packages for GCC cross-compilers. These compilers use multi-arch libraries. These are built from the sources for GCC 4.9, as described on the Debian wiki. The bulk of the logic to do cross-building is already present in the Debian sources. These packages use very light patches to the debianization.

These packages are a stop-gap measure, until packages such as these can be pushed into the main Debian repo. When that happens, I will stop building these.

These are rebuilt every week, so things should be reasonably up-to-date. I attempt to build compilers targeting

  • armel
  • armhf
  • mips
  • mipsel
  • powerpc
  • arm64

Some subset of these usually fails, and will not be built for that week. As of this writing (2014-07-20), mipsel and powerpc are failing. Compilers for the following languages are built:

  • C
  • C++
  • Fortran
  • Java
  • Go
  • Objective C
  • Objective C++

Packages are generated weekly by a script and not tested by anybody. Use at your own risk.

Debian/sid is targeted. Wheezy can probably be made to work, but that's left as an exercise for the adventurous.


Add to your /etc/apt/sources.list:

deb unstable main
deb-src unstable main

Tell APT to pull in packages for the target architecture. For instance:

dpkg --add-architecture armel

Tell APT to trust these packages, do

wget -q -O - | sudo apt-key add -

Now we're ready to go:

aptitude update
aptitude install gcc-4.9-arm-linux-gnueabi


This repository is populated by a script and a few patches; those appear here:
