I have a Linux/Ubuntu DLL that depends on libboost_thread-mt.so.1.38.0 (As shown in the picture below). I've tried various ways including building my own version of LibBoost 1.38.0 yet none of my methods have worked. I was wondering if 1.38.0 is available precompiled on earlier versions of Ubuntu or if my architecture (64 Bit) is not compatible with LibBoost. Any pointers on how to fix this error are greatly appreciated. http://joshua-ferrara.com/imgoid/images/1332518188.png Best Regards, Josh
