I do not know much about the LIBGRX library, but I do know something 
about C in general.  Don't you need something other than an empty main 
function to have the program do anything?  Are your graphics calls in 
another function?  If so, you probably need to call this function from 
within main().

Does everyone else concur, or am I missing something here?

You might try posting a minimal program so we can pick it appart.  
Sometimes it's hard to give helpful hints if we can't see what you're 
doing wrong.

Hope this helps,
