After a long period of brokenness, cross-toolchains for debian are back. We dropped the ball rather over Wheezy as we expected new multiarch-built cross-toolchains to be ready much sooner than this so failed to take care of wheezy properly which has been a pain for a lot of people. Sorry about that.
However there are now some working cross-toolchains again, in time for Jessie. These did not make it into Jessie proper, due to infrastructure changes which are needed for packages with cross-arch dependencies, but the deadline did provide the impetus to get it all working. These are essentially the same packages that have been available from secretsauce.net for much of 2014, but covering more architectures. They are now available from emdebian.org along with cross-gcc-defaults packages and a modified pkg-config to make that work with multiarch and crossbuild-essential-<arch> packages to pull in dpkg-cross and libc-dev:<arch>, especially if using sbuild where the default config expects that package to exist. cross-binutils packages are in Jessie proper. amd64 and i386 packages are available, targetting all the other jessie release arches (armel, armhf, arm64, mips, mipsel, powerpc, ppc64el) Installation and status info is maintained at https://wiki.debian.org/CrossToolchains Frontends for cpp, gcc, g++ and gfortran are available now. gobjc and gccgo are building now and should be uploaded in a couple of days. These crosstoolchains are not multilibbed, but are co-installable, so install a compiler for each arch/triplet you wish to target. They have multiarch dependencies so you will need to enable the target architecture as a foreign arch to install, as documented on the above page. Unlike older Emdebian cross-toolchains, these are configured to use multiarch paths for libraries and headers so you should use multiarch methods to build (which debian appears to be lacking any docs for - we should do something about that). The same cross-toolchains are also available in unstable, but are not always installable due to multiarch skew (after a new gcc, libc or linux upload). And they have caused some controversy so expect changes and instability. Also mips is currently broken as the native compiler didn't build in the current upload. Please report back if they are useful to you. The Emdebian.org server got a) hacked and b) moved, so the old toolchains (squeeze, wheezy and older) are currently non online, but will be restored reasonably soon.
