--- Comment #17 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-01-07 12:55:39 UTC --- But that is not a requirement. The requirement is using a C++ compiler that works out of the box (compiler configured in a path where its shared libraries aren't found by the dynamic linker isn't), or making sure through LD_LIBRARY_PATH or tweaking spec (to add -rpath) that the compiler works out of the box, or compiler which supports -static-libstdc++.
