Hi, I've been trying to debug the mac ppc, which fails with: src/runtime/BCKernel/thread.c:126: failed assertion `rval==0' The reason is that sem_init returns -1, to indicate error, and an error number that indicates ENOSYS: The function sem_init() is not supported by this implementation. See http://www.opengroup.org/onlinepubs/007908799/xsh/sem_init.html for more details. Of course, I have no idea why sem_init isn't supported, or why its required for a non-threading example, or anything else - just this might help someone else debug this error. Thanks Neil
Hi
Specific comments and pitfalls:
1. The thread function sem_init is not implemented on Darwin
whereas the functions sem_open/sem_close is not implemented on Linux.
That's why there is some juggling with the initialization of the
semaphores in the code.
That seems to be the reason its not working, at a point at the correct fix.
Thanks
Neil
