It’s been a while since I posted a Emacs build walk-through, one version of macOS has come and gone and a new major version of Emacs has arrived, let’s get to it.
Building Emacs has only gotten easier since macOS Catalina, so, let’s make this quick.
- Autoconf and Automake. Used to build the build configuration.
- GnuTLS for making SSL connections. Replaced the more commonly available OpenSSL in Emacs 26.
The easiest way to get everything, save Xcode (which you already have) is with Homebrew. In fact, the Emacs 27.1 build process now plays nicely with Homebrew, making this my preferred method.

(master is the development branch, emacs-27 is the current released version.)
The version 27.1 build process knows about Homebrew and where it stores
stuff. In the past you’d have to add the path to
(“/usr/local/opt/texinfo/bin”) to your PATH, but this is no longer necessary.
Emacs 26 and possibly early versions of 27 also had problems finding Libxml2 but this has been corrected as well.
In short, as long as you have installed the prerequisites with Homebrew, you no longer need to do anything to your environment.
