Darwin doesn’t have a futex but it’s got ways to provide the locking. It would require you to modify the original source though (or you can provide your own wrappers to the futex calls for Darwin). see: https://preshing.com/20111124/always-use-a-lightweight-mutex/ <https://preshing.com/20111124/always-use-a-lightweight-mutex/> Rich

Hello,

In a library code source coming from Linux, I've got the following error on macOS 10.13: simple_components/os/linux/synchronization_linux.c:29:10: fatal error: linux/futex.h: No such file or directory #include <linux/futex.h>

I can't found any futex.h in /usr/include.

Is there macOS or Darwin alternatives to Futex?

Thanks, Pascal. http://blady.pagesperso-orange.fr
