[ruby-core:118989] [Ruby master Bug#20706] Can't build Ruby on macOS Sonoma and Sequoia due to: ignoring duplicate libraries, archive member '/' not a mach-o file in libruby.3.3-static.a

["wkoszek (Adam Koszek) via ruby-core" <ruby-core@ml.ruby-lang.org>]

Issue #20706 has been updated by wkoszek (Adam Koszek).


It looks pretty recent to me:

$ rustc --version
rustc 1.80.1 (3f5fd8dd4 2024-08-06) (Homebrew)

I think there are some warnings that I get even on a PC with Ubuntu 24.04. So I don't worry about those. But the linker error is basically preventing me from using Ruby / RVM. 

Trying to ditch Xcode.app now -- will reinstall to see if it helps.

Hi,

I had the same problems with macOS Sonoma and (after an upgrade) Sequoia -- something about my macOS makes it impossible to build Ruby.
Upon an upgrade to Sequoia, I did Xcode upgrade, and then CommandLine tools download.
Then I did "sudo xcode-select --reset"
I'm trying ruby-3.3.4 and ruby-3.2.5 -- both have the same result from below.

Steps:

wget  https://cache.ruby-lang.org/pub/ruby/3.3/ruby-3.3.4.tar.gz
tar xzf ruby-3.3.4.tar.gz
cd ruby-3.3.4
script
./configure
make -j

I'm attaching the transcript.

This ticket has this warning too:
https://bugs.ruby-lang.org/issues/20283

But looks like it's a warning. For me it's somehow an error.
