Sorry your message arrived while I was typing mine. I just removed both these lines from my cmakelibcxx script: rem -DLIBCXX_CXX_ABI="libsupc++" ^ rem -DLIBCXX_LIBSUPCXX_INCLUDE_PATHS="/mingw/lib/gcc/x86_64-w64-mingw32/4.8.1/include/c++;/mingw/lib/gcc/x86_64-w64-mingw32/4.8.1/include/c++/x86_64-w64-mingw32" ^
and that removed the __GLIBCXX__ problem. I'm not sure why I put these lines in my scripts in the first place, as I don't know what they do. They have been there for ever! Hmmmm. Ok, I'll try and work with these lines missing and see what happens and if everything runs ok. Thanks for your help with this.
