Hi,

a quick question: I compiled Emacs from Git and now want to upgrade it.
Is it enough to pull a fresh version and then make && make install?

Best,

It should be enough to "git pull" into the same repository where you
have the previous version, and then "make && make install".

A simple git pull is all you need to do in order to get new
commits. After that do a make && make install.

Ciao, Gregor

If "make" fails, try "make bootstrap".

What do you do if that fails as well?

In the directory that contains the git checkout execute:

git clean -f -d -x

That ensures that you are using a pristine source directory. Then

make

If that fails, then the build is broken due to some erroneous change
made by the developers. Wait one day or two, "git pull" again, repeat
the build process. If the build is still broken, on Emacs do

M-x report-emacs-bug

including details about your setup (compiler, library versions, etc) and
the output of the build at the failure point.

It is possible to check out a previous vesion (one day ago, for
instance) instead of waiting for a fix upstream, but that requires and
slightly more complicated git usage.

You do:

[you@yourbox /path/to/emacs-git-repo-copy] $ make distclean &&
./configure [--config-flags] && make

Case closed :)

FWIW, I just do "make" and never run "make install".
