I will probably build new packages soon based on libc++ and linked to the newest version of Qt, but until then you basically have two alternatives: compile Gecode from sources with libc++, or compile Qt from sources with libstdc++. >> On the command line, I think Xcode may have changed the default paths for >> frameworks, you could try adding -F/Library/Frameworks to your compiler >> options. >> > That almost did the trick.
