Adding ARM Cross generation patch to gcc and binutils specfiles
Hi - Building on the work of Lennert Buytenhek and David Woodhouse I recently uplevelled the spec files for gcc and binutils they did for gcc-4.1.2 and binutils-2.17.50.0.18 to work with recent rawhide gcc and binutils. The goal of the spec changes is to allow rpmbuild to also build cross gcc and binutils packages which can co-exist with the normal host ones, it makes it easy then to build cross kernels or bootloaders which may otherwise be difficult when your native system doesn't work yet ^^ The patched spec files need to be built like this: $ rpmbuild -ba --define binutils_target armv5tel-redhat-linux-gnueabi rpmbuild/SPECS/gcc.spec # rpm -i rpmbuild/RPMS/x86_64/armv5tel-redhat-linux-gnueabi-binutils-2.20.51.0.12-2.fc15.x86_64.rpm $ rpmbuild -ba --define=cross_target armv5tel-redhat-linux-gnueabi rpmbuild/SPECS/gcc.spec The binutils patch is simple and small (against binutils-2.20.51.0.12-2.fc15): http://warmcat.com/binutils-cross12.diff The gcc patch (against gcc-4.5.1-5.fc15): http://warmcat.com/gcc-cross12.diff is not small or selfcontained and may have some rough edges, but it works to build functional cross packages that don't conflict with the host install so its heart is at least in the right place or, best from my point of view, the patch can be cleaned and merged with the normal gcc spec. I see Hans looks after arm-gp2x-linux-gcc which is also stuck in a gcc-4.1.2 timewarp that maybe my uplevelled patch can also help. Maybe Jakub and Hans could eyeball the patches and see if there is a path to allowing cross packages going on just by rebuilding with the right rpmbuild parameters. -Andy -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel

With that said the arm-gp2x-linux-* packages could use some love, which I've been failing to give them due to lack of time. Mostly what they need is packaging of some more cross-compiled libs (like SDL_mixer and other SDL_foo's) to make the chain usable to compile a wider range of gp2x programs.
