Comment (by cehoyos):
Replying to [comment:2 highgod]:
> If disable the pthreads, there will be no "static pthread_mutex_t
atomic_opencl_lock = PTHREAD_MUTEX_INITIALIZER;", so is there any other
better way to implement it?
I don't know but this is not the important point about this issue (imo):
configure currently does not fail for --enable-opencl if pthreads is not
available, please fix the conditions for opencl in configure so that it
already fails when configuring, not later at compile time.
(I suspect that you should use the functions from libavutil/atomic.h but
maybe that does not work with opencl?)
