Subject: Emacs 23.1 configure/Makefile: MAKEINFO=no inconsistent with test
 for $(MAKEINFO)=off
Date: Thu, 30 Jul 2009 21:23:55 +0200

Hello,

for http://ftp.gnu.org/pub/gnu/emacs/emacs-23.1.tar.gz
on KUbuntu 6.06, after running configure, I got a Makefile with

  MAKEINFO=no

(which seems to originate from configure line 5319), but all the tests
in the Makefile compare to "off", like

  test "$(MAKEINFO)" = "off";

Therefore "make install" failed with

  makeinfo is missing - cannot build manuals

After manually adapting Makefile to

  MAKEINFO=off

"make install" it worked fine.

==> either configure should create "Makefile=off",
    or the Makefile tests should check for "no".

Thanks for Emacs!

Helmut

That's what you should get if you don't have makeinfo and don't pass
the configure option --without-makeinfo.

Yes, because "off" is used to indicate that you've explicitly disabled
the need for makeinfo, rather than it just being missing.

As you can see from the context of this line in the Makefile, "off"
and "no" have different meanings.

No, you should pass the configure option --without-makeinfo.


There is a real issue here though, and it is that the top-level
Makefile does not check whether or not it needs to rebuild any manuals
before checking the value of MAKEINFO. (The manuals are pre-built in
the tarball, specifically so that you don't need makeinfo to install a
released version of Emacs.) This only shows up when doing `make install'.

  * Makefile.in (info-real): Don't ignore errors from doc Makefiles.
  (info): Don't give an error in the absence of makeinfo - let the doc
  Makefiles do that, if the info files need rebuilding. (Bug#3982)
