Error Apple Mach-O Linker (id)

Question

I have an error below:

Can anyone help me out? It used to work correctly. I have no idea what I changed in the sources of the project. But I am sure that nothing has changed in this FMDatabase.h and .m.

Answer 1

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

Answer 2

I once got this error when I initialized the values ​​to the 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.

Answer 3

This is a pretty old post, but maybe it still helps someone.

I had the same problem, there was a solution for me: I accidentally linked the .m file in one of the headers instead of the .h file. Just modified this to properly link the .h file.

Answer 4

Check if you need to import the framework.

Answer 5

I solve the problem by updating my framework.

Answer 6

I decided to run Clean.

Then you can create.
