ioquatix commented 1 year ago

It looks like your error is that you didn't install the ruby-dev packages which is required for compiling native gems. 2nd to last screenshot.

urchymanny commented 1 year ago

facing the same issue

tarcieri commented 1 year ago

@urchymanny that error means you need to install the Ruby development environment for your Linux distro.

It's not an issue specific to nio4r.

urchymanny commented 1 year ago

Facing same issue on my M2 Mac Mini, does Mac require Linux headers ?

tarcieri commented 1 year ago

Mac requires XCode. Perhaps if you paste the full error we can help you better.

This particular error should be easily fixable, if no one has made a PR, I'll try to look at it over the weekend.

Same problem.

ioquatix commented 1 year ago

@urchymanny what hardware and system are you compiling on?

On Termux on an Android! @urchymanny

ioquatix commented 1 year ago

I see, so it's a different compiler that's more strict, causing the issues.

thesamesam commented 1 year ago

I see, so it's a different compiler that's more strict, causing the issues.

Yeah, this is Clang 16 which makes -Wincompatible-function-pointer-types an error by default. I think this is a (partial) dupe of (or the other way around, w/e) https://github.com/socketry/nio4r/issues/290.

Cheers for the quick fix!

ioquatix commented 1 year ago

Yeah, that makes sense, I suppose the original code wasn't really valid.

thetermuxuser commented 1 year ago

Ohk i get it! No problem then

thetermuxuser commented 1 year ago

Thanks for the help!
