I note that the command line says -pthread but does not list any libraries. In current GCC using -pthread in the link command does some slightly complex library choosing on FreeBSD. So, hypothesis: -pthread does not work correctly in the extremely ancient GCC 2.95.3 you are using. Unfortunately by my reading of the current GCC code I don't understand how -pthread is supposed to work when using FreeBSD before version 5. Normally using -pthread adds a thread library, but on FreeBSD before version 5 this only happens when not using -shared. I'm not sure what is supposed to happen with -shared, as in your case. I suggest figuring out how to write a shared library that uses thread on your ancient platform, and then do that rather than assuming that -pthread does the right thing. Ian
