问题
I'm trying to compile a project that depends on 2 third party static libraries.
The issue is that both third parties have included the same set of "utility" classes in their static library distribution, meaning that I am getting dozens of duplicate symbol errors when both are added to my project.
Is there a way for me to force the project to compile and/or ignore one of the duplicate symbols somehow?
I found a similar question with answer here two static libraries with duplicate symbols in Xcode but I am interested to see if there is a compiler flag that might do the trick (please note that in this case I am assuming that both symbols represent the same object).
Thanks Rog

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.
