Yes, I linked to those libraries intentionally, since cmake seemed to detect a 32-bit architecture. Since I have a 64-bit OS, I'd like to figure out how to get cmake to detect the appropriate architecture. Thats a low priority for me right now, and I posted the real reason for the crash above. Thanks for your response.
