libgccjit 11.3 replace .so file to .dylib let `libgccjit_lib_dir` become empty.

[ccqpein]

I update gcc and libgccjit this morning and the libgccjit.so file in /usr/local/opt/libgccjit/lib/gcc/ changed to libgccjit.0.dylib. And it make libgccjit_lib_dir become empty line 1128

Sounds like they keep this change in future versions disscussion.

Do we have configuration filter or options can make build-emacs-for-macos use libgccjit.dylib instead of .so?

Thank you

I also got this issue after brew upgrade. when build emacs, will got this error:

And emacs-plus have been fix it. https://github.com/d12frosted/homebrew-emacs-plus/issues/455

@Eason0210 thanks for your reply. Depends on the discussion in the link, looks like the master version of emacs can accept dylib now.

I change line 1129 to File.join(libgccjit_root_dir, 'lib/gcc/*/libgccjit.0.dylib*') and it works.

But do we need to keep the old .so options there? I dont know ruby, so I left my solution here and wish author or someone else can make a PR for it.

Yes, the master branch have been update to accept dylib. see here : https://github.com/emacs-mirror/emacs/commit/faa29fa2c9e9d5a5d7544a1a39b2a89cf57a8439

I change line 1129 to File.join(libgccjit_root_dir, 'lib/gcc/*/libgccjit.0.dylib*') and it works.

Good to know it works for you. I change it to File.join(libgccjit_root_dir, 'lib/gcc/*/libgccjit.dylib*') and it works as well.
