Failing to build

[ezzatron]

I was going to try this module out, but it fails to build on my macOS Catalina machine with the following error when trying a yarn add:

error /path/to/project/node_modules/posix-semaphore: Command failed.

Thought you might appreciate a heads up. Let me know if you need any further info about my system.

EDIT: Updated error output after fixing macOS command line tools warnings.

Hi there, thanks for the report! Looks like it's some issue with the combination of node-gyp/nan/nodejs versions. I tried a few of the combinations I thought were working in the past, but failed to get a working build on macOS Catalina as well.

We probably need to rewrite the nodejs - C++ intercommunication glue code (currently uses nan), but I don't have time to invest in that right now, I'll let you know if that changes! You could maybe take a look at N-API if you care to, it's probably a few hours worth of investment if you don't have experience with it, probably a few tens of minutes if you do.

Hey I faced the same set of issues and managed to fix this locally for myself, going to issue a PR soon. Two things here went wrong:

• sem_getvalue is deprecated on OSX as it doesn't support unnamed semaphores. Fortunately it was only used inside debug statements, so I removed them.
• this lib was using some deprecated nan APIs, I updated them. This thread was helpful as I felt like nan was poorly documented.

[dbousque]

Awesome, thanks @szymonWojdat ! Let's continue the discussion in the PR.

Thanks to you both @ezzatron and @szymonWojdat , the fixes are available in the new version 1.0.0!
