use Inline C => Config =>
                LIBS => '-lfmodex';
[download]

That won't link to fmodex_vc.lib. You would need:

                LIBS => '-lfmodex_vc';
[download]

But then, since fmodex_vc.lib is in a non-standard location, you also need to tell the linker where fmodex_vc.lib is located. Therefore:

 LIBS => '-LC:/full/path/to/lib -lfmodex_vc';
[download]

Since the lib is in the cwd, the following might suffice:

 LIBS => '-L. -lfmodex_vc';
[download]

However, I'm not sure whether a relative path works with Inline::C ... if it doesn't, then provide the full path.

Cheers,
