Hi, I see the following files. I'm wondering why '-mt' is appended to the file. I don't see such thing on ubuntu. I want to make the compilation of some source code using libboost_thread compatible on both Mac and Ubuntu. Does anybody know how to do it? Thanks. /opt/local/lib/libboost_thread-mt.dylib /opt/local/lib/libboost_thread-mt.a -- Regards, Peng
