>> Which module are you trying to compile? Duh. I really should read the subject. I'll blame my lack of coffee at that time in the morning. > : undefined reference to `pthread_create' This is the problem - you need to make sure everything's trying to link against pthread (and not the other threading library, the name of which I've forgotten). On FreeBSD, I have to add "LDFLAGS=-pthread" to make sure the thread linking is done correctly. The exact solution probably depends on your distribution. Which distro are you using?
