Right, usually though, you dont care about the linker error.

... until you've fixed all the compiler warnings mentioning
unresolved symbols...

You will be more interested in the compiler warnings because
they will tell you exactly where in your source code that you
are mentioning missing symbols such as 'g_threads_got_initialized'

... while you go ahead and modify your source to use new and
updated apis, after fixing those compiler warnings... you
should not get the linker error anymore.
