Iain,
Any idea why this isn't failing universally? On all of the
machines tested here with 'make bootstrap', the linkage of libcc1.so
finds
the necessary libstdc++ from the set of flags...
-L/sw/src/fink.build/gcc50-5.0.0-1000/darwin_objdir/x86_64-apple-darwin13.4.0/libstdc++-v3/src
-L/sw/src/fink.build/gcc50-5.0.0-1000/darwin_objdir/x86_64-apple-darwin13.4.0/libstdc++-v3/src/.libs
-L/sw/src/fink.build/gcc50-5.0.0-1000/darwin_objdir/x86_64-apple-darwin13.4.0/libstdc++-v3/libsupc++/.libs
as I posted earlier in this thread. Why wouldn't Dominique be getting
those emitted in his build and shouldn't they suffice?
