xcode中的Apple Mach-O链接器（Id）错误

Question

I am using xcode to work with SNAP package ( http://memetracker.org ). When I Build, I get a few "Apple Mach-O Linker (Id) Error"

I read that I may have to add the right framework but I do not know how I can find what the right framework is.

Undefined symbols for architecture x86_64:
    "_Env", referenced from:
        _main in cliquesmain.o
    "ExeStop(char const*, char const*, char const*, char const*, int const&)", referenced from:

Answer 1

Have you added this memetracker "library" correctly? Check out the tab "build phases", if not then there is probably your problem.

I assume you have the code/library in your project, so you have auto-completion, but to link this library you need to specify where to find it.
