Hi Now that my hacked binutils builds gold rather than ld I can't work out how to make a gcc which uses it. From the docs it would seem to be something like: gccGold = wrapGCC (gcc43_real.gcc.override { stdenv = overrideInStdenv stdenv [binutilsGold]; }); but while that builds gold it uses the standard binutils ld. ? thanks Rohan
