Information about installing Emacs from source on macOS seems to be surprisingly sparse, so putting it all here together for easy reference. If it matters, the Emacs version I installed was 27.0.50, on macOS 10.14.
Pick from either
email@example.com:emacs-mirror/emacs.git(or have both as different remotes).
gnutls, and make sure you have Command Line Tools installed
xcode-select --install. Additionally, you need the SDK headers.
./configure(with any other flags you may want, I have
vtermsupport), then finally
make install, which will compile it into an application binary for your perusal.
brew install texinfo echo 'export PATH="/usr/local/opt/texinfo/bin:$PATH"' >> ~/.zshrc # or follow the instructions given by brew info brew install gnutls open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg git clone git://git.sv.gnu.org/emacs.git cd emacs ./autogen.sh ./configure --with-modules # flag optional make install # takes some time, grab caffeinated beverage of choice
Various error messages that you may encounter:
checking for makeinfo... /usr/bin/makeinfo configure: error: You do not seem to have makeinfo >= 4.13, and your source tree does not seem to have pre-built manuals in the 'info' directory. Either install a suitable version of makeinfo, or re-run configure with the '--without-makeinfo' option to build without the manuals.
xml.c:23:10: fatal error: 'libxml/tree.h' file not found #include <libxml/tree.h> ^ 1 error generated. make: *** [xml.o] Error 1 make: *** [src] Error 2
You need to install the SDK headers as above.
