I was following the tutorial for making SFML with C++11 support, but I kept getting linker errors with anything that used anything from the standard library. The one thing I had to add that wasn't in the tutorial was setting
CMAKE_C_FLAGS to be
stdlib=libc++ too (not just
CMAKE_CXX_FLAGS).
This is exactly how I had to do it:
export CMAKE_OSX_ARCHITECTURES=i386;x86_64
cd <sfml folder>
mkdir build
cd build
cmake -G "Unix Makefiles" -DCMAKE_CXX_COMPILER=/usr/bin/clang++ \
-DCMAKE_C_COMPILER=/usr/bin/clang -DSFML_BUILD_FRAMEWORKS=ON \
-DSFML_INSTALL_XCODE4_TEMPLATES=ON \
-DCMAKE_CXX_FLAGS="-stdlib=libc++" -DCMAKE_C_FLAGS="-stdlib=libc++" ../
make -j8
sudo make install
Notice the
-DCMAKE_C_FLAGS="-stdlib=libc++" at the end. Without it, I kept getting the following errors when making an Xcode project that used clang & libc++ for C++11 support:
Undefined symbols for architecture x86_64:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
Hopefully I'm not crazy...
Also, thanks for SFML! I'm really looking forward to 2.0's official release (and then I'm really looking forward to 2.x when OpenGL ES 2.0 is supported!)
