Good Evening, I've been looking at writing a program that uses both shared libraries (dlopen/dlclose) and POSIX threads. I however haven't had any success in my simple tests. After doing some research via google I found that due to -shared pthreads wasn't linked into the shared library, fair enough, it's logical. My question is, is it possible to write programs that use pthreads in their shared libraries on FreeBSD. For compiling the base program (that is the program that loads the shared libraries) I've been using: gcc -export-dynamic -pthread master.c -o master And for each of the shared libaries I've been using: gcc -shared -pthread slave.c -o slave.so I had intended to use some form of message queue using a pthread condition. The sample C files I've been using can be located at: http://planet.alastria.net/~peter/hackers/master.c http://planet.alastria.net/~peter/hackers/slave.c Any light would be greatly apreciated, Cheers, Peter. -- Peter Wood <peter@alastria.net> :: Tel +44 7974 799440help
