Description John Guthrie 2007-02-15 01:34:39 EST
Description of problem:
I just tried running autoconf on a version of asterisk from subversion.  I
received the following errors:

configure.ac:31: error: possibly undefined macro: AC_USE_SYSTEM_EXTENSIONS
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
configure:3799: error: possibly undefined macro: _AC_PATH_PROG_FEATURE_CHECK
configure:3800: error: possibly undefined macro: _AC_FEATURE_CHECK_LENGTH

It still managed to generate the configure script, but it had these macros
embedded in it, as shown by the terminating error message:

checking for a sed that does not truncate output... ./configure: line 3799:
syntax error near unexpected token `SED,'
./configure: line 3799: `     _AC_PATH_PROG_FEATURE_CHECK(SED, sed gsed,'

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1.Download subversion using
svn co http://svn.digium.com/svn/asterisk/team/oej/res_auth asterisk
2.cd asterisk
3.run aclocal
4.run autoconf
Actual results:
Error given above.

Expected results:
No error and a configure script that runs without errors.

Comment 1 John Guthrie 2007-02-15 01:39:41 EST
My reason for filing this bug is I was wondering what was the timetable, if any,
for upgrading autoconf?  I just checked the gnu.org ftp site, and autoconf-2.61
has been out since November.  I have verified that the above macros are in both
2.60 and 2.61.  I understand that things might be a little complicated at the
moment with the merge and all.
Comment 2 Karsten Hopp 2007-02-15 06:33:37 EST
autoconf-2.61 was released after FC-6 came out. There's currently no timeframe
for an update as there are no known security issues and we're quite busy with
merge stuff. Please use autoconf-2.61 from rawhide if you need this feature.
