My idea is to provide special stdenv expressions that will contain in the path additional cross compilers. As most expressions for programs accept a stdenv parameter, we could substitute this parameter with the special stdenv, which will have a generic builder that attempts the usual "--target=..." and can additionally have an env variable like "cross" with the target architecture set. So, finally we could have additional expressions like this: bashRealArm = makeOverridable (import ../shells/bash) { inherit fetchurl bison; stdenv = stdenvCross "armv5tel-unknown-linux-gnueabi"; }; Meanwhile it does not work - I still cannot get the cross-gcc to build. I think it does not fill the previous expressions with a lot of noise, so I think it may be a good path to follow. I only touched some files of the current stdenv: gcc-4.3, kernel headers 2.6.28, glibc 2.9, ... I tried to use the gcc-cross-wrapper, that may be very outdated. Maybe I will update it, or update the gcc-wrapper expression to make it fit the cross tools, but meanwhile I even cannot build gcc, so I have not tested the wrapper. This new idea on cross compiling is not similar to that of the nixpkgs/branches/cross-compilation, which mostly added bare new expressions for anything to be cross compiled, if I understood it correctly. I cared not to break anything of the usual stdenv in all this work. svn path=/nixpkgs/branches/stdenv-updates/; revision=18343 |
