Notes: - The sRGB patch is now a simple text-replacement, as diff/patch files seem to just fail. Even Homebrew's emacs formula does it this way. - Removed fullscreen patch, as Emacs 24.4 includes fullscreen support on OS X, both native and pre-Lion style fullscreen.

# build-emacs-for-osx
|
|
|
|
Use this script at your own risk. It currently works for me on my own machine,
|
|
which as of writing is:
|
|
|
|
* OS X 10.8.5 (12F45)
|
|
* Xcode 5.0 (5A1413)
|
|
|
|
Your luck might vary. Do note that it does not build a universal application.
|
|
The CPU architecture of the built application will be that of the machine it
|
|
was built on.
|
|
|
|
|
|
## Why?
|
|
|
|
I've been using [Homebrew][] the past few
|
|
months to build from HEAD. Homebrew comes with a number of patches, including
|
|
the [sRGB][] patches which I use.
|
|
|
|
[homebrew]: http://mxcl.github.com/homebrew/
|
|
[srgb]: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8402
|
|
|
|
Homebrew does not build a self-contained application though, which caused
|
|
issues for me when I needed to rollback to a specific build. I found the
|
|
easiest way to build a completely self-contained Emacs.app nightly from a
|
|
specific date with custom patches was to do it manually.
|
|
|
|
So I decided to quickly hack together a script to automate that manual
|
|
process. The code is a horrible hack, but it (seemingly) works as I'm writing
|
|
this in Emacs built with it.
|
|
|
|
|
|
## Usage
|
|
|
|
Myself I run the following command which will download a tarball of the
|
|
`master` branch, apply the sRGB patch, and build Emacs.app:
|
|
|
|
./build-emacs-for-osx
|
|
|
|
Or for example if you want to build the `emacs-24.3` tag, run:
|
|
|
|
./build-emacs-for-osx emacs-24.3
|
|
|
|
Resulting applications are saved to the `builds` directory in a bzip2
|
|
compressed tarball.
|
|
|
|
|
|
## Internals
|
|
|
|
I decided to pull Emacs' source from a GitHub [mirror][repo] rather than the
|
|
official Bzr repo cause I'm not familiar with Bzr, and GitHub lets you easily
|
|
download tarballs of any branch, commit or tag. And the tarballs from GitHub
|
|
are just over 30MB, compared to ~1GB to pull the offical Bzr repo.
|
|
|
|
[repo]: https://github.com/mirrors/emacs
|
|
|
|
The only option passed in `./configure` is `--with-ns`, meaning the resulting
|
|
application only supports the CPU architecture of the system is was built on.
|
|
There might be more side-effects to, but I haven't noticed any.
