mu --with-emacs --HEAD does not install mu4e

[brabalan]

For some reason, the configure step of mu is

./configure --prefix=/usr/local/Cellar/mu/HEAD --with-gui=none

with the '--disable-dependency-tracking' flag missing. It seems that, as a consequence, mu4e is not built.

Following the comment at the end of issue #15081, I manually configured and built mu in /Library/Caches/Homebrew/mu--git doing

./configure --disable-dependency-tracking --prefix=/usr/local/Cellar/mu/HEAD --with-gui=none
make
make install

and mu4e was correctly installed.

This isn't the reason; also it actually is passed, it is just not printed out by the UI because it is such a common flag.

OK, then I don't see what the difference is between building it manually and through the recipe.

It probably needs --env=std

The following works:

EMACS=$(which emacs) brew install mu --with-emacs --HEAD

The EMACS variable is used to determine Emacs' version in configure.ac:63. It needs to contain the path to Emacs.

This is a great workaround, thanks a lot.

Should be resolved by #16733, which I just pushed.
