For the threads part, at least, you need to link your program to the pthreads library. Do this by adding '-pthread' to your link command line. Not sure about the semaphores, though...

Hi, How do I compile a program that uses threads and semaphores? Although I included thread.h and semaphore.h in my program, gcc keeps saying that it can't find references to sem_wait, sem_post, sem_init and pthread_create. I'm using gcc 3.2.2 on a RedHat 9 box Thanks, Andre __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free web site building tool. Try it! http://webhosting.yahoo.com/ps/sb/
