MacOS: Compliation of Jinx failed. Issue related to Homebrew?

[alecStewart1]

Hello!

For awhile, Jinx was working fine, and until the most recent version. I get the follow error:

gcc -I. -O2 -Wall -Wextra -fPIC -shared -o jinx-mod.dylib jinx-mod.c -I/usr/include/enchant-2 -lenchant-2
jinx-mod.c:19:10: fatal error: 'enchant.h' file not found
#include <enchant.h>
         ^~~~~~~~~~~
1 error generated.
Jinx: Compilation of jinx-mod.dylib failed

I've instead enchant via Homebrew:

$ homebrew info enchant
https://abiword.github.io/enchant/
/usr/local/Cellar/enchant/2.6.8 (29 files, 297.8KB) *

And enchant.h seems to be in the following places:

$ fd -t f 'enchant.h' /
/usr/local/Cellar/enchant/2.6.8/share/doc/enchant/enchant.html
/usr/local/Cellar/enchant/2.6.8/include/enchant-2/enchant.h
/System/Volumes/Data/usr/local/Cellar/enchant/2.6.8/share/doc/enchant/enchant.html
/System/Volumes/Data/usr/local/Cellar/enchant/2.6.8/include/enchant-2/enchant.h

So /usr/local/Cellar/enchant/2.6.8/include/enchant-2/enchant.h and /System/Volumes/Data/usr/local/Cellar/enchant/2.6.8/include/enchant-2/enchant.h.

I don't know what changed in the newest version of Jinx, but I've just now ran into this issue.

Oh, this could be an Emacs 30.0.50 thing, too.

If that can help anyone, I manually compiled the shared library doing the following steps:

• in jinx-mode.c I replaced the line #include <enchant.h> with #include "/opt/homebrew/include/enchant-2/enchant.h",
• I changed the compile command to: gcc -I. -O2 -Wall -Wextra -fPIC -shared -o jinx-mod.dylib jinx-mod.c -L/opt/homebrew/Cellar/enchant/2.6.8/lib/ -lenchant-2

These are obviously quick and dirty hacks…

[J-Loudet]

Maybe you set something with homebrew differently than me, but I believe the header file should be at

/usr/local/Cellar/enchant/2.6.8/include/enchant-2/enchant.h

I put that path as it's shorter (😅) and, on my machine©, it is a symlink to /opt/homebrew/Cellar/enchant/2.6.8/include/enchant-2. I do not have a /usr/local/Cellar folder.

I haven't been a macOS user for long so I don't know the intricacies of homebrew.

Generally, the problem seems to be that pkgconf/pkg-config is not executed correctly on your system or doesn't find Enchant. Then as a last resort, Jinx falls back to the "default path" of "/usr/include/enchant-2", which then fails.

FYI, a similar problem seems to have happened with PDF-tools after some change in how brew installs packages vedang/pdf-tools#269 (comment)

I got to this discussion after I restarted Emacs and jinx greeted me with 'enchant.h' file not found 😅

[alecStewart1]

Ah, I think I found one thing. Check /usr/local/lib/pkgconfig on your system and if PKG_CONFIG_PATH has that path.

EDIT 1: Nevermind. I think I need to try reinstalling Emacs first. For me /usr/local/lib/pkgconfig has a lot of symlinks to the pkg-config files that homebrew installs along with a lot of packages. I'll see if after reinstalling Emacs if this fixes things.

EDIT 2: Nope.

This worked for me. Since I use straight, I had to do one more step by linking the compiled dylib to /straight/build/jinx/

If that can help anyone, I manually compiled the shared library doing the following steps:

* in `jinx-mode.c` I replaced the line `#include <enchant.h>` with `#include "/opt/homebrew/include/enchant-2/enchant.h"`,

* I changed the compile command to: `gcc -I. -O2 -Wall -Wextra -fPIC -shared -o jinx-mod.dylib jinx-mod.c -L/opt/homebrew/Cellar/enchant/2.6.8/lib/ -lenchant-2`

These are obviously quick and dirty hacks…

Inspired by this commit, adding the following lines to my use-package declaration seems to be enough to solve the compilation issue without having to manually modify files:

  :init
  (setenv "PKG_CONFIG_PATH" (concat "/opt/homebrew/opt/glib/lib/pkgconfig/:" (getenv "PKG_CONFIG_PATH")))

Thank you for this. Right now this is the easiest workaround.

[alecStewart1]

This works for me as well.
