macOS link fails: cargo run --example locks

Open cameronelliott opened this issue 3 years ago • 0 comments

On macos, the following two functions don't appear to be available. So the following fails to link or run: cargo run --example locks You can see the log at the end of this post.

These are the missing funcs on macOS:

pthread_rwlock_timedrdlock()
pthread_rwlock_timedwrlock()

Interestingly enough, pthread_mutex_timedlock is also not available on macOS, but an implementation has been provided under if #[cfg(target_os = "macos")] {... I wonder if there might be equivalents for pthread_rwlock_timed..lock() where that came from? It also appears glibc offers a replacement mentioned HERE

I am checking to see the authors can suggest where to get a good replacement. Or if the authors have a good idea about how to fix this? Thanks, Cameron
