Apple Mach-O Linker (id) Error

I have an error below:

Could someone help me out? It used to work properly before. I have no idea what I have changed in the project sources. But I am sure that I never changed anything in that FMDatabase.h and .m.

I solved by performing a Clean .

Then could Build.

I solve the problem by updating my framework.

This is a quite old post, but maybe it still helps somebody.

Just had the same problem, for me the solution was: I accidently linked an .m file in one of the headers instead of the .h file. Just changed that to properly link the .h file.

I once got this error when I was initializing values to constants defined in the global scope in my .h file.

Solved the problem, by declaring them in the header, and initializing them in the .m file.

The relevant portion of your error is ld: duplicate symbol _OBJC_IVAR_$_FMDatabase.databasePath. For some reason, the linker (ld) is trying to link FMDatabase twice. Check to see if you have multiple copies of it in your project.

Check if you import framework which required.
