Avoid dylib from linkage fixing

[daviderestivo]

Hi,

I'm currently maintaining a brew formula for GNU/Emacs. Since some time a new branch of Emacs is being develped allowing LISP code compilation into native code (dylib). More details here: http://akrl.sdf.org/gccemacs.html

I'm trying to modify my formula in order to support this new feature (native-comp branch) of GNU/Emacs HEAD. The installation is successful but it seems that after the "install" phase homebrew changes the DYLIB ID of the native compiled Elisp code breaking someway those libraries:

==> Changing dylib ID of /usr/local/Cellar/emacs-head@28/28.0.50_1/Emacs.app/Contents/native-lisp/28.0.50-x86_64-apple-darwin19.6.0-280c4c724fff373c5b7192112ad4147c/PY-b5-9da27250173071085086a7aed29fd29d-7a2e0ead8fc81e02717b53d465b7c866.eln

I would like to know if there is a way to avoid this behaviour.

Thanks in advance and regards,
Davide

I think the best way forward is to report this bug to homebrew/brew so it can be fixed instead of turning it off.

@SMillerDev, sure I can do it ... thanks for the quick answer :)

[daviderestivo]

Done ... thanks.

That's homebrew/homebrew-core, which contains just the software that's shipped. Not the actual brew tool. That one is homebrew/brew.

Ok then I'll move it to the brew tool ... thanks.

EDIT: someone already did it...
