BUGREPORT: Problem with automake/autoconf scripts

BUGREPORT: Problem with automake/autoconf scripts

[Martin Oberhuber]

[-- Attachment #1: Type: text/plain, Size: 1466 bytes --]

Hello,

I have found a problem with the automake and autoconf scripts installed
in /usr/bin for switching between the DEVEL and STABLE versions of
automake and autoconf.

The bug leads to breaking automake or aclocal on scripts where some
text follows the AC_PREREQ line (like, for instance, in the DDD 
configuration script).

In Detail: automake allows a line like
AC_PREREQ(2.13)dnl
where some text follows the closing parenthesis after the version number.
The trailing text is not correctly eliminated by the SED script
which extracts the version number in the automake/autoconf scripts
distributed.

For correcting the bug, replace the following line:
VER=`sed -n -e '/AC_PREREQ/s/[^(]*(\([[:digit:]\.]*\))/\1/p' < $infile`
with the corrected line:
VER=`sed -n -e '/AC_PREREQ/s/[^(]*(\([[:digit:]\.]*\)).*$/\1/p' < $infile`

in all autoconf/automake scripts:
aclocal autoheader autoreconf autoupdate autoconf automake autoscan ifnames

corrected versions of these scripts are in the attached tarfile.

Cheers,
Martin

Thanks -- I've corrected this in the primary source packages here:
   http://www.neuro.gatech.edu/users/cwilson/auto-wrapper/
     automake-scripts-1.5b.tar.bz2
     autoconf-scripts-2.52a.tar.bz2

Also, I've put updated cygwin-style packages for Corinna here:
   http://www.neuro.gatech.edu/users/cwilson/cygutils/testing/
     automake-1.5b-1.tar.bz2
     automake-1.5b-1-src.tar.bz2
     autoconf-2.52a-1.tar.bz2
     autoconf-2.52a-1-src.tar.bz2

Finally, I've also made a note to correct this in the (very very 
experimental) libtool scripts.

Next time, however, it would be better to generate a patch against the 
source code (automake.in, aclocal.in) and not simply create new output 
files.  (That's kinda like shipping a corrected '.exe' file without 
incuding the source.  Not quite, because THESE ".exe" files are just 
text, but still...)

And also a changelog.

Thanks,
Chuck
