Building "vanilla" emacs on macOS (summary)

Building "vanilla" emacs on macOS (summary)

[Jean-Christophe Helary]

Since I always forget, I decided to put together a summary of the process:
https://mac4translators.blogspot.com/2021/09/building-vanilla-emacs-on-macos-with.html

Let me know if there are obvious mistakes.

TIA.

Thanks for documenting it. I would like you to create two sub-sections
for essential and recommended brew packages. You have already specified
the essential packages without which Emacs won’t build. If you install
the following packages then these will be picked up by the ‘configure’
script without explicitly passing any options. I have arrived at this
list after several iterations.

--8<---------------cut here---------------start------------->8---
brew install \
	 libjpeg \
	 libxpm \
	 libtiff \
	 libpng \
	 librsvg \
	 jansson \
	 lcms2 \
	 giflib
--8<---------------cut here---------------end--------------->8---

Pankaj,

Thank you very much for this list. I'll be adding it to the post.

I am sure, your article will be useful to many. Thanks for mentioning me
there. Now, my ego-search will have one more result. :-D

In it's default set-up Emacs on macOS won't use libjpeg, libtiff,
libpng and giflib even if they're installed as those image types are
all built into NSImage, which is the default. So they're not
essential.

I'm not sure about libxpm, I think we have specific code in Emacs
itself to deal with them... Or maybe I'm thinking of some other X
bitmap format...?

Alan,

I've modified the post accordingly. Thank you both for your help.

Ok. Then there is a bug in the generated ‘configure’ script. In my
trials, ‘./configure’, said ‘no’ for the above libraries when I didn’t
install the Homebrew packages and ‘yes’ otherwise.

that's true, but you don't require them as long as configure reports:

    Does Emacs use native APIs for images?                  yes (ns)

If you have both native API and the libraries built-in you can make
Emacs use either, although I can't remember off-hand how to force it
to use the libraries.

Now, if you're building Emacs 27 it won't report that, but it will
still prefer the native image API, and I'd suggest whatever else you
do you don't actually want to use giflib as the native gif support is
less buggy.

Thanks for this info, Alan.
