Alexandre Oliva <aoliva at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aoliva at gcc dot gnu.org --- Comment #15 from Alexandre Oliva <aoliva at gcc dot gnu.org> --- FWIW, this patch breaks at least non-bootstrap builds when CXX is set to "ccache g++". gnatlink attempts to insert various gnat flags between ccache and g++, and that fails. Before the patch, it would work because the CXX passed to gnattools would always start with ../../xg++. I agree the change is right, though, and I'm not sure what to recommend other than not using ccache, or using it in the symlink mode, when building ada in non-bootstrap mode.
