Thanks a lot! > Nope, not sure what's going on there. Ubuntu 12.04 uses glibc 2.13 (these functions have been around since 2.3.4). We're including pthread.h in that file, cmake already sets up the links against pthread, and your cmake shows this: -- Performing Test HAVE_PTHREAD_SIGMASK -- Performing Test HAVE_PTHREAD_SIGMASK - Success ... -- Performing Test HAVE_PTHREAD_SETSCHEDPARAM -- Performing Test HAVE_PTHREAD_SETSCHEDPARAM - Success So you're finding the right things. I'm running 12.04 on this machine I'm currently on and just built from that tarball myself with no problems. Any chance you've changed around your system at all that could have an effect? Tom
