xcode 5 ld: 11 duplicate symbols for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Question

When trying to build my project, I constantly get this error saying ld: 11 duplicate symbols for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation) I recently tried to implement GPUImage to my project, would that have anything to do with it? Also I read similar problems but none had my solution.

No one can help unless to provide more specific details about the linker errors. — rmaddy, Oct 23 '13 at 22:09

Wild guess, have you maybe imported a .m file instead of the .h anywhere?

Again ... your wild guess just save me some serious headache's too. I'd upvote you more if it were possible. Thx. – BonanzaDriver Apr 05 '14 at 18:00

It turns out I had implemented my .m file from another view controller and in that view controller I implemented the first view controller, so it was like a loop.

Thanks for your answer though Gabriele, it helped me to find the loop.

there are another reason this error often happens is accidentally importing the .m file instead of the .h.
