Print a pointer using the appropriate formatter:

printf("%p\n", im);

It's also a good idea to check that im and tag are returned not-null after the function calls.

And also call FreeImage_GetFileType(fname, 0) on a separate line to make sure it does return a valid type too.

Then insert a lot more printf statements to see exactly which function fails.

just general debugging advice...

If it's too important then run it through a debugger (not Perl's, I mean gdb or something).

btw, to add on what syphilis said about making sure the same libraries are loaded (for Inline::C and gcc), make sure that the same compiler flags are used too. There must be a Makefile somewhere created by Inline::C (edit: for your specific script. In linux is in the same dir) which will show you exactly how the C-part of your script is compiled.
