m4 error in bootstrap

m4 error in bootstrap

[Francesco Potorti`]

I am doing a `make bootstrap' of the TEMACS_21_1_RC branch.  I get this
as the very first lines:

cd ~/gnu/emacs-pretest/
make -k bootstrap
cd /home/pot/gnu/emacs-pretest && autoconf
aclocal.m4:30: error: m4_defn: undefined macro: _m4_divert_diversion
autoconf/c.m4:801: AC_PROG_CC_STDC is expanded from...
aclocal.m4:30: the top level
make: *** [/home/pot/gnu/emacs-pretest/configure] Error 1
make: Failed to remake makefile `Makefile'.

   You need autoconf 2.13, or else touch configure to make it newer than
   configure.in.

I have autoconf 2.53 installed on a Debian sarge (testing) system.

Yes, that's your problem.

Ouch!

Okay, the helpful Debian maintainers made an autoconf2.13 package wich
installs a wrapper that does autodetection and calls the right autoconf
version... 

It works for Emacs.

Thanks.

Sorry, Francesco, I forgot to tell you that the RC branch needs
Autoconf 2.13, and cannot work with a newer Autoconf.  The switch to 
Autoconf 2.5x was done on the trunk only.

Is there any way to make it compatible with both 2.13 and 2.5x?  Many
of the current GNU/Linux systems comes with 2.5x.  I'm not sure that
every vendor is as considerate as Debian and providing both versions.

Sorry, I don't know enough about the differences to answer that, but it 
sounds like Francesco's experience says NO.

Please note that you don't need Autoconf to build Emacs from a source 
tarball (since Autoconf was already run before the tarball was 
prepared).  So this is not a real issue for most users.

    Is there any way to make it compatible with both 2.13 and 2.5x?

I agree that would be a good thing to do.  I hesitated to install
the new configure.in which requires Autoconf 2.53, but it would be nice
to make the old one support both Autoconf versions if that is possible.

The problem is that the macros _AC_VERSION_COMPARE and AC_ACVERSION do not
exist any more in 2.50+, and it is difficult to rewrite the condition so
that it works in both 2.13 and 2.50+.

I don't see either of those macros in the configure.in file of RC.
Could you show me the code in RC's configure.in that is the problem?

See aclocal.m4.
