error LNK2001

Please help. I have the error:

Callbacks.obj : error LNK2001: unresolved external symbol _BESSEL_FUNC_mp_ITILDE@12
Debug/mmqueue.exe : fatal error LNK1120: 1 unresolved externals

Bessel_func is the name of the module, and Itilde is the name of the function I am trying to use. I know this is an error that several people have asked about on this forum, but I have read those posts and still haven't figured out my problem.

The Bessel_Func module is a fairly complicated mess, but I can replicate the problem with a much simpler module that compiles just fine if the module is in the same file as the main program, but generates this error if the library and .mod file are elsewhere.

Thanks.
