Or upstream should add an explicit --tag=CC, or rename the file extension. Good catch, that certainly ties in with what that link I found was saying. Hmm, there are two harfbuzzes, one old, one new; one has .cc files, the other .cpp files. It appears that they both do actually use C++ features, but perhaps in a limited way; as long as they don't throw exceptions or use RTTI or any of the standard C++ library functions, they could not need linking against libstdc at all. In that case maybe upstream's solution would be to add "-fno-exceptions -fno-rtti" to the CXXFLAGS and "--tag=CC" to the LDFLAGS. Don't know which code base the distro package is based on though; let's wait and see what Yaakov has to say. cheers, DaveK -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
