Lluís Batlle i Rossell f3c23487a2 Adding a new version of the gcc-wrapper, named gcc-wrapper2, in order not to rebuild ... stdenv. In this gcc-wrapper2 I made the ld-wrapper.sh to handle the linking with shared objects through direct pass as ld command arguments of the absolute path to shared objects, instead of using the -L/-l combinations. cmake 'FindXXX.cmake' modules make a strong usage of the dynamic linking directly passing the absolute path to the shared object to the linker, and as our wrapper did not add any -rpath for those, writting the nix expressions for some cmake packages resulted in a lot of tricks, compared to using this gcc-wrapper2. This gcc-wrapper2/ld-wrapper.sh should become the gcc-wrapper/ld-wrapper in a stdenv update. I also updated some cmake expressions to use this gcc-wrapper2, and reduced its tricks. I also updated the cmake setup-hook for it to make cmake not touch any rpath decided at build time, when running the 'make install' of makefiles created by cmake. svn path=/nixpkgs/trunk/; revision=18885		2009-12-10 22:19:52 +00:00
