Complete Freeze on MacOS / M1

[c0nn3r]

When I run icyc on MacOS, the REPL seems to "hang" and not execute anything.

cyclone> (write 'hello-world)

The cyclone command has the same behavior when trying to compile a file. It completely pins the CPU when either using the REPL or the cyclone command. I am using a M1 chip, which I think might have something to do with it.

Well, that is concerning. Thanks for the report @c0nn3r

Everything has been tested to work on MacOS though I suspect the test runners are not using an M1.

[justinethier]

I suspect atomic operations from concurrency kit (libck) are not working properly on M1. If that is the case perhaps they could be replaced, EG by using polyfills and/or atomic operations from C11.

This seems to have been fixed, in particular, brew install -s --HEAD ck will build the patched ck from head.

[justinethier]

That's great news, thanks for the update @BracketMaster !

I wonder if this requires the latest changes from head or if it will also work with the 0.7.1 pre-release.

[justinethier]

@c0nn3r can you confirm if this is still an issue?

[c0nn3r]

Without upgrading concurrencykit with brew, this is still an issue.

[joaogui1]

This is still an issue, is there some kind of fix?

[justinethier]

@joaogui1 According to @BracketMaster you can do brew install -s --HEAD ck to install the latest libck and fix this. I would suggest giving that a try if you are running into this issue.

Please let me know how it goes. Unfortunately I do not have M1 hardware over here and cannot test this directly...

[joaogui1]

That works, thanks!
Sorry for the ping, I thought @c0nn3r's answer meant the fix had stopped working

[justinethier]

@joaogui1 No worries. Unfortunately that reply is rather confusing.

Just so we are all on the same page is brew install -s --HEAD ck required?

[joaogui1]

Yep, I first had to uninstall my version of libck and then run that
