I'm trying to use SFML as my graphics backbone for a C++ game engine. I'm also using the V8 JavaScript engine. The problem is, to get V8 to compile, I've got to use -stdlib=libstdc++, and to get SFML to compile, I've got to use -stdlib=libc++. Obviously, I can't use both, so how can I work around this?
I'm using Xcode on a Mac Mini, by the way, but it doesn't work through the terminal either.
SFML gives me these errors when using -stdlib=libstdc++:
Undefined symbols for architecture x86_64:
"sf::String::String(char const*, std::locale const&)", referenced from:
And V8 gives me these errors when using -stdlib=libc++:

You need to recompile SFML and/or V8 with the same std lib since they are not compatible. I don't know for V8 but SFML should be able to work with libstdc++ too (set CMAKE_CXX_FLAGS and CMAKE_C_FLAGS to -stdlib=libstdc++ when generating the makefile). You won't be able to use C++11 features with libstdc++, though.
