Building from source on 5.15.0-43-generic #46-Ubuntu x86_64 GNU/Linux

[Andreas Röhler]

Hi,

while building from source of recent trunk and emacs-28.1 went fine,

fails on emacs-26.3 and emacs-27.2


WRT to the latter below the final messages from make:

This is not the HEAD of the emacs-27 branch.  There's no emacs-27.2
branch in the repository (see "git branch -a").

That isn't emacs-27, it's the 27.2 release tag.  You should write this
instead:

  git checkout emacs-27
