Re: [Mingw-users] Mingw Sockets Library Semaphore.h

I added the "libpthreadGC2.a" lib and the "libpthreadGCE2.a" lib hoping that they were the missing libraries that pthreads in semaphore.h was referencing. No, I don't know whether or not I need to add more libraries to the compiler. The Sockets library said that you have to add libwsock32.a and libws2_32.a; no other libs were mentioned (http://www.alhem.net/Sockets/tutorial/install.html). Of course, the instructions were written with the assumption that you are attempting to compile under cygwin, which I am not. Could that be why the pthreads lib is missing? Is there another pthreads lib I should be using? I retrieved libwsock32.a and libws2_32.a from the system32 directory, but I wasn't able to find a "libpthreads.dll" in there.
