frum fails on new Macbook Air M2; tried all solutions

[blakeperdue]

I've googled this issue for hours now and give up. I've tried all the solutions I could find online yet I am unable to use frum to install any Ruby versions. A log is below.

My setup:
Macbook Air M2
frum v0.1.2

> arch -arm64 frum install 2.7.5

I was also having difficulty building Ruby. I'm using:

frum version 0.1.2
macOS Monterey 12.6 (M1 Macbook/Apple Silicon)

My errors output similar to this:

  "_rb_enc_set_base", referenced from:
      _Init_encdb in encdb.o
  "_rb_enc_set_dummy", referenced from:

I solved this for myself by looking at Homebrew's ./configure options for Ruby:

https://github.com/Homebrew/homebrew-core/blob/db82d67243e0a9829335e08ba12274f5dce62dea/Formula/ruby.rb#L67-L81

And I used this command:

frum install 3.1.2 --enable-shared --disable-silent-rules --without-gmp

And it worked! 🎉

I wish I understood why that works -- given there's linker errors, I think --enable-shared might be doing the trick ¯\_(ツ)_/¯

Thanks a lot! I had the same issue, tried your solution and it worked! 🙌

[gilsoncav]

Same here. it worked!
Many thanks @eddieantonio 😀

[monfresh]

@eddieantonio and others who might wonder why --enable-shared is required, it's due to an incompatibility between version 14.x of Apple's command line tools and Ruby. Ruby fixed the issue in 3.1.3 and 2.7.7, but they haven't been released yet. Once they are released, the --enable-shared flag would not be needed anymore. I've written about this in detail here:

https://www.rubyonmac.dev/how-to-install-ruby-on-macos-12-6-apple-silicon

As for the other flags from Homebrew, --disable-silent-rules doesn't do anything because it's not recognized by Ruby. And although --without-gmp is a Ruby configuration option, it won't make a difference.

@monfresh Thanks! That's a write-up!
