Use this script at your own risk. As of writing (2020-02-02) it works for me on
my own machine to build the
emacs-27 release branch. My machine is a late-2016
13-inch Touchbar MacBook Pro runnning macOS 10.15.2 and Xcode 11.3.
Your luck may vary.
The build produced does have some limitations:
- It is not a universal application. The CPU architecture of the built application will be that of the machine it was built on.
- The minimum required macOS version of the built application will be the same as that of the machine it was built on.
- To use new features available from master or pre-release branches, which have not made it into a official stable release yet.
- Homebrew builds of Emacs are not self-contained applications, making it very difficult when doing HEAD builds and you need to rollback to a earlier version.
- Builds from emacsformacosx.com has had no new nightly builds for two months right now.
- Both Homebrew HEAD builds, and nightly builds from emacsformacosx.com are
built from the
masterbranch. This script allows you to choose any branch you want. I am currently building from the
emacs-27branch which is the basis of the upcoming Emacs 27 release, meaning it should be more stable than
- All Homebrew formula listed in the
Brewfile, which can all easily be installed by running:
Then to download a tarball of the
master branch, build Emacs.app:
If you want to build the
emacs-27 git branch, run:
If you want to build the stable
emacs-26.3 git tag, run:
Resulting applications are saved to the
builds directory in a bzip2 compressed
The script downloads the source code as a gzipped tar archive from the GitHub mirror repository, as it makes it very easy to get a tarball of any given git reference.
It then runs
./configure with a various options, partly based on what David
build-emacs scripts do, including
copying various dynamic libraries into the application itself. So the built
application should in theory run on a macOS install that does not have homebrew,
or do no have the relevant brew formula installed.
Code quality, is well, non-existent. The build script started life a super-quick hack back in 2013, and now it's even more of a dirty hack. I might clean it up and add unit tests if I end up relying on this script for a prolonged period of time. For now I plan to use it until Emacs 27 is officially released.
