There are several alternatives to dumpbin; it should be fairly obvious how to use any of them. If you've come this far without awareness of dumpbin, the Microsoft documentation of it is easily accessible.
If you run dumpbin /symbols on your .obj or .lib file, you should be able to see whether the spellings of the linker symbols match up. The stdcall version, obsolete for 8 years, but still favored by some, where the number of bytes of stack used in the call is appended to the linker symbol, after the @ symbol, won't work with the current cdecl system. Recompilation from source code would avoid this problem.
The MKL forum is the place to ask about that subject.
