BUILD FAILED (macOS 12.0.1 using ruby-build 20211019)

[andersennl]

Hi, I'm trying to install Ruby 2.6.5. During the installation I see an error which I'll post below. I'm not sure what could cause the error and if this is the right place to address the issue. In case it's relevant I'm using macOS 12.0.1 on an Apple "M1 Pro" MacBook. Please let me know in case you need more information (for instance the full log). Thank you!

Looking at the ruby-build issues (https://github.com/rbenv/ruby-build/issues) it looks like there are several people reporting issues with OSX 11, so I'm not surprised you've run into an issue with OSX 12. I'm still on OSX 10 so I don't have any way to debug this right now.

I was actually just reading through issues over there and found RUBY_CFLAGS="-w".

My installation worked with the following command: RUBY_CFLAGS="-w" asdf install ruby 2.6.5.

Thanks again.

For any newcomer, I am using MacBook Air (M1, 2020) MacOS Monterey 12.2.1. When I try to install Ruby 2.6.5 I encountered a similar issue(BUILD FAILED (macOS 12.2.1 using ruby-build 20210928).

I gave command: RUBY_CFLAGS="-w" asdf install ruby 2.6.5 a try, it also worked for me.

I'm using a M1 Mac as well with macOS 13.0.1 and I tried this command with the ruby version 3.2.2 but it didn't work for me. I still got the message that the build had failed.

Hey @devAffe Just guessing, did you install a c library before? It's worth checking your global environment variables again, if there are CFLAGS defined it might cause this error, in this case we can consider using direnv to manage environment variables by directory.
