[gecode-users] Compilation problem on MacOs with Gecode 4.3

Hi Vijay,
the main difference seems to be that you had -stdlib=libstdc++ on your command line. The missing symbols were probably mismatches on std::ostream (all the linker errors referenced that symbol), so I guess that you compiled Gecode with libc++ but later tried to compile your example with libstdc++? In particular if you link against Qt, you have to use the same standard library that was used to compile Qt.
Cheers,
Guido
