clang: error: linker command failed with exit code 1 (use -v to see invocation)

Hey all. Trying to use TouchJSON to do some JSON-y stuff. I followed the read me for the library to the meter I think, but every time I try to compile I get this error. I don’t know much about Xcode (I’ve only been learning Obj-C recently) so I’m clueless about this. Any ideas?

    Try to remove “Experimental” folder (and files inside, of course).

    README

    Be aware that the code in the Experimental subdirectory of Source is
    just that and may not have been extensively tested and/or have extra
    dependencies

    So it could be a problem about extra dependencies (but always make sure if your project already have linked all dependency libraries/framework)
