error: possibly undefined macro: AC_USE_SYSTEM_EXTENSIONS
Last modified: 2007-11-30 17:11:57 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): 2.59-12 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. Additional info:
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.
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.
