Hello. Some time ago I've created patches for Debian gcc-3.3 source package to build cross-compilers out-of-the-box. Both gcc-3.3 and g++-3.3 are built, together with libgcc1, libstdc++5, libstdc++5-3.3-dev, libstdc++-5-3.3-pic, libstdc++5-3.3-dbg packages. Library packages are built similar to ones created by dpkg-cross. Separate cpp package is not needed for gcc-3.3, because it uses integrated cpp by default.
These paches are already in the mainstream package that is currently in Debian-sid. Readme.cross file there explains how to build cross-compilers. I tested these for arm target. The built cross-compiler packages, together with library and lib-dev packages from debian sid for arm architecture converted by dpkg-cross (see paches for dpkg-cross in Debian BTS), lead to clean and consistent build environment. I already suceed to build qt-embedded and opie it this environment, and am quite satisfied with the results. (next step here is to use Debian build tools and procedures to auto-build ipk's that will have consistent dependency information) It should be possible to build cross-compilers for other architectures too. I'm looking for bug reports and feedback on my compiler-related work.
