ruby >= 3.2 bottles have an incorrect path in RbConfig::CONFIG["AR"] about homebrew-core

[Bo98]

Likely affects MacPorts too - but I haven't checked for sure.

Can open an issue shortly, and maybe a pull request too if I find the time.

Apologies for the delay: https://bugs.ruby-lang.org/issues/20499

Fixed upstream at ruby/ruby@8277cf0

I copy here the whole RbConfig::CONFIG.
Note that NM is also incorrect and has the same problem ("NM"=>"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/nm --no-llvm-bc",).

My brew doctor output says Your system is ready to brew. and am still able to reproduce my issue.

I ticked this box even though the output says differently but I am absolutely certain that would change nothing, and the issue reproduces 100% regardless of that brew doctor output. It's an issue that is simply part of the prebuilt [email protected] and [email protected] bottles.

---

One more thought: this problem could likely also be solved if the bottle was built on a system which does not have XCode installed, because then CRuby wouldn't find those executables. Or maybe there are ways to tell CRuby which toolchain to use (the CLT is better if it's always guaranteed to be there for Homebrew) rather than letting it guess.

[Bo98]

This is caused by ruby/ruby@038f9ad.

[eregon]

Indeed, I see:

bash-3.2$ cc -print-prog-name=ar
/Applications/Xcode_15.0.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar
bash-3.2$ cc -print-prog-name=nm
/Applications/Xcode_15.0.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/nm
bash-3.2$ cc -print-prog-name=ld
/Applications/Xcode_15.0.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld

Interesting that LD above is not affected but AR and NM are.

Any idea how to fix this in Homebrew?
Maybe AR=ar NM=nm ./configure ... or so could work.

Maybe it should be changed in CRuby? But that wouldn't fix it for existing 3.2 and 3.3 releases.

cc @nobu since you did this change and might know more about it

[Bo98]

This bug will likely affect all macOS Ruby builds (unless Xcode is missing) so definitely seems like an upstream fix is desirable here.

[eregon]

Agreed, although for the common case of compiling ruby from source on the same machine it's not an issue because then either no XCode and fine anyway, or XCode is installed and then those paths will most likely work fine (unless XCode is later uninstalled).

[eregon]

@Bo98 Could you file an issue at https://bugs.ruby-lang.org/ ?

Also, since this basically only happens with Homebrew builds of CRuby (Homebrew is one of the very few to have binary builds of Ruby on macOS), it seems worth working around in parallel in Homebrew until it gets fixed & released in CRuby.
