What you were trying to do

Install and run emacs-plus.

What happened (include command output)

brew install emacs-plus [OPTIONS] worked. But running emacs got me the following error:

dyld: Library not loaded: /usr/local/opt/imagemagick/lib/libMagickWand-7.Q16HDRI.8.dylib
  Referenced from: /usr/local/Cellar/emacs-plus@27/27.1/Emacs.app/Contents/MacOS/Emacs
  Reason: image not found
[1]    10452 abort      emacs

To check the linkage, I did the following:

$ brew linkage --test emacs-plus
Broken dependencies:
  /usr/local/opt/imagemagick/lib/libMagickCore-7.Q16HDRI.8.dylib (imagemagick)

I spent a while fighting with this last night. I don't really know much about the issue, but I was able to manually fix it by doing the following:

cd /usr/local/opt/imagemagick/lib
ln -s "libMagickCore-7.Q16HDRI.9.dylib" "libMagickCore-7.Q16HDRI.8.dylib"
ln -s "libMagickWand-7.Q16HDRI.9.dylib" "libMagickWand-7.Q16HDRI.8.dylib"

brew reinstall --build-from-source emacs-plus@27 is a local workaround. I think a better solution is to provide a new bottle which does not have the linkage issue.

That actually didn't seem to work for me when I was trying to solve the issue yesterday.

Nice. Brew team released new version of imagemagick, which doesn't force rebuilding of dependant formulas, meaning they will break at 'runtime' thanks to dynamic linking. It's not the first time, definitely not the last time. Let me just rebuild the bottle.

P. S. I am sorry to hear things like 'I spent a while fighting with this last night'. 😿

[d12frosted]

Okey, could not produce the bottle.

λ brew bottle emacs-plus@27
==> Determining d12frosted/emacs-plus/emacs-plus@27 bottle rebuild...
==> Bottling [email protected]_sur.bottle.3.tar.gz...
==> Detecting if [email protected]_sur.bottle.3.tar.gz is relocatable...
Error: Bottle contains non-relocatable reference to /usr/local/Homebrew!

Not sure what exactly causing this error, unfortunatelly don't have much time to dig into it. So I am going to disable bottle, so at least the bleeding stops. Will dig into bottling issue later.

FYI, I'm not sure if this is related but brew audit --strict --online emacs-plus@27 returns the following diagnostics (I do not include the style warnings here):

Thanks @soonho-tri . I think I addressed the warning about site-lisp somewhere, but now I can't remember where exactly. The second looks like the culprit here. Seems like something related to portable dumper. Will investigate.

EDIT: Now I remember where I addressed the first warning - in my attempts to automate bottle building.

fyi Happens for emacs 28 as well. @lucassz hack worked, thanks.

[d12frosted]

Since it's old and we already recovered from that change, closing the issue. But leaving it as pinned for future visibility.
