Hello, I'm trying to install gcc-4.7 and have problems with the posix threads, especially with the PTHREAD_ONCE_INIT decalration in the pthread.h file. When installing, it often ends up with this error: ‘PTHREAD_ONCE_INIT’ undeclared here (not in a function) static pthread_once_t create_key_once = PTHREAD_ONCE_INIT; So, it would be very helpful to understand what the definition of "PTHREAD_ONCE_INIT" is about. If it's a fixed size or address value and what it's role when handling threads. Moreover there are some different versions of pthread. The one wich created the error above, i can't find now. -- View this message in context: http://old.nabble.com/Understanding-Threads-tp33964421p33964421.html Sent from the gcc - Help mailing list archive at Nabble.com.
