Background: Termux is a Linux terminal environment that runs under Android. It provides a terminal version of Emacs 25.3.

However, I would like to build Emacs directly from the master branch in the archive. However, I have stumbled on two problems:

1) The emacs build recipe for termux patches a number of files. I will need to apply those patches as well.

2) When running autoconf.sh (to generate the configure script), I get a number of errors. (I can't copy-paste from the android device, unfortunately). When running autoreconf -fi -I m4 the following is emitted:

/PATH/TO/bin/m4: m4_syscmd subprocess failed
configure.ac:5191: error: expected source file, required through AC_LIBSOURCES, not found
m4/gnulib-comp.m4:177:gl_INIT is expanded from...
configure.ac:5191: the top level
autom4te: /PATH/TO/bin/m4 failed with exit status 1
...

Does anybody has a step by step description on how to build Emacs from source on Termux? Alternatively, do you have any suggestion on how I should modify the build scripts myself so that they get the latest version rather than a specific one? (The build scripts downloads the sources as a tar.gz file, presumably with a pre-generated configure file, so a great help would be if someone would provide the latest sources the same way.)

Latest source tarball is available from

  • Thanks, this is just what I need! I'll try to build Emacs on termux and get back with a full recipe. – Lindydancer Dec 6 '17 at 12:36
