Build failed in v3.3.4 on Mac Silicon using asdf

[lulunac27a]

I tried installing Ruby version 3.3.4 on Mac silicon, but failed to build. I tried arch -arm64, but still get a warning:

/opt/homebrew/bin/rbenv-install: line 164: rbenv-hooks: command not found

I even use asdf install ruby 3.3.4 --architecture=arm64, but I still get the same warning above, what can I do?

Hi, it looks like the greadlink binary installed by Homebrew on your system is busted. rbenv will optionally use the greadlink tool if it finds it in PATH, but is not necessary for normal operation of rbenv. However, executing greadlink on your system fails due to a dynamic library that failed to load; presumably due to the fact that it was built for amd64 architecture (and you're running arm64).

The greadlink tool is provided by the "coreutils" Homebrew formula. You could try uninstalling it: brew uninstall coreutils

General protip: you can check which Homebrew formula provides a binary by looking at where the binary symlink resolves to:

$ ls -l `which greadlink`
lrwxr-xr-x  1 mislav  admin  37 Aug 27 14:26 /opt/homebrew/bin/greadlink -> ../Cellar/coreutils/9.5/bin/greadlink

The first directory under "Cellar" is the name of the Homebrew formula.

Alternatively, if something depends on "coreutils" on your system, you could reinstall it instead of uninstalling it: brew reinstall coreutils. That should recompile it for the correct architecture.

Still get the same error while running greadlink after I use brew reinstall coreutils:

Puzzling. I do have "coreutils" but I do not have the /opt/local directory on my machine, so I do not know what /opt/local/lib/libintl.8.dylib is.

1. What is your output of otool -L /opt/homebrew/bin/greadlink?
2. Does /opt/local appear at all in your environment variables? env | grep opt/local
3. Did you ever use MacPorts to install software on this machine in addition to Homebrew?

[mislav]

⚠️ Potentially dangerous: if this was an artifact from an outdated setup that's no longer necessary, you could try deleting /opt/local entirely. My hunch is that this directory is not needed for anything Homebrew-related at all, since Homebrew keeps everything under /opt/homebrew. Furthermore, macOS does not keep anything under /opt/local to the best of my knowledge. However, removing this directory might break other software if they ever linked to it.

/opt/local is used by MacPorts. My guess is that @lulunac27a either has MacPorts installed now, or used to, and they didn't properly uninstall it. Homebrew and MacPorts are not compatible with one another.

[monfresh]

And as part of properly uninstalling MacPorts, it also means removing any references to it or the /opt/local folder from your shell startup file (such as ~/.zshrc)

[lulunac27a]

/opt/homebrew/bin/greadlink:
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1345.100.2)
