Similarly, I can't get 3.0.0-preview2 or 3.0.0-dev to build on Mojave with similar-ish errors...

Similar build failures were posted to the Ruby bug tracker for Ruby 2.6.2:

https://bugs.ruby-lang.org/issues/15726

3.0.0-preview1, 2.7.1 and 2.7.2 build fine, however.

As a follow up to my comment above, I've created a ticket in the Ruby issue tracker along with a fix for the bigdecimal issue. See here for details:

https://bugs.ruby-lang.org/issues/17486

Basically, reverting the following commit will allow builds to run successfully on darwin again:

ruby/ruby@ed01cc8

@naro143 I get the same error (Segmentation fault: 11) when installing ruby 3.0.0. Did you solve it?

[naro143]

@v3rmin I don't know how to solve this problem. ruby 3.0.0. has the same problem.

Hi, all.

Can you try with the following instructions?

$ sudo rm -rf /Library/Developer/CommandLineTools
$ xcode-select --install
$ sudo xcode-select -s /Library/Developer/CommandLineTools

I think your developer toolchain is broken by macOS or Xcode upgrade installation.

[AlexMarold]

@hsbt Thank you!
I had the same problem and your instructions fixed it for me.

[naro143]

@hsbt
Thank you!
solved this problem👏

[dark-panda]

@hsbt This does not resolve the issue. I did what you asked on a Catalina Macbook Pro and the issue is still present. Applying the patch revert I mentioned does however work. I also have access to a Big Sur Macbook Pro that I can try with once the upgrade is done.

[hsbt]

I couldn't reproduce it. ruby-build is working fine with my Catalina and Big Sur environment.

[dark-panda]

This also happens when building from source directly from a fresh git clone so it's not an issue with ruby-build per se, but with Ruby itself it seems. As to why you are unable to reproduce, I'm not sure, but I've had the issue now on Mojave, Catalina, and I will soon check on Big Sur.

I've posted to the Ruby bug tracker so we can perhaps follow the progress there to see if anyone else has a similar issue. I can say with certainty that reverting patch in question definitely resolves the issue for me at least on the v3_0_0 tag and on master, but as to why I'm experiencing it specifically is a different matter.

[arrowcircle]

Hey! I have the same issue with Catalina and reinstalling command line tools didnt help. Any ideas how to fix it and install ruby?

[asgeo1]

I was having this same issue installing ruby 3.0.2 on Catalina. I got it to work by applying a patch that reverts this commit

1. Save this into a file called my_custom_patch_file.patch

2. Install via rbenv:

$ export RUBY_CONFIGURE_OPTS="--with-openssl-dir=$(brew --prefix [email protected])"
$ rbenv install --patch 3.0.2 < /path/to/my_custom_patch_file.patch

This advice was perfect, and still relevant for ruby 3.1.2. Thanks

@asgeo1 This patch worked for me on my Apple Silicon M1 with Monterey 12.5 installing Ruby 3.1.2 via Homebrew and rbenv.
