Run your app with the following environment variables set:
export MONO_LOG_LEVEL=info
export MONO_LOG_MASK=dll
Numerous messages will be printed to the console whenever Mono attempts
to load a library, and one of these messages should be why the library
can't be loaded.
Frequently the problem is that the library is improperly linked; mono
(effectively) loads libraries using dlopen(3) with RTLD_NOW set, so if
your library depends on a symbol from another library but wasn't linked
against that library, you will get errors loading it.
You can also use http://www.jprl.com/dltest.c to test this scenario (see
the comments for compile commands).
If that still fails, you can reply to the mailing list with the Mono
output attached.
