I am in the middle of moving our development from the std STL to STLPort and I am having a problem with two Athlon boxes. SuSE Linux 9.0 gcc 3.3.1 STLPort 4.6.2 Boost 1.31 I am changing an existing application to use STLPort and I have successfully completed the transition on a number of Intel boxes. When I try to build on an Athlon box I get the following error message: undefined reference to `boost::thread::thread[in-charge](boost::function0<void, std::allocator<boost::function_base> > const&)' I'm linking against libboost_thread-gcc-mt-p-1_31 and libboost_date_time-gcc-mt-p-1_31. I can't see an obvious solution so I'm hoping someone has solved this problem already. ----------------------- Kenny Chamber http://gem-hs.org/contact.html
