Duplicate symbols issue with 2 third party libraries in Xcode
Try merge them into one file via libtool (libtool -o merged.a file1.a file2.a) or check How can I avoid “duplicate symbol” errors in xcode with shared static libraries? or/and Solving “Duplicate Symbol” Error When Setting Up GorillaLogic’s FoneMonkey 5
Just find the duplicate symbol file and rename one of the library corresponding files. Be aware that you should check all compiled sources of the project that you are renaming. Xcode won't change the references automatically.
