Bug #8179: configure.in requires newer Autoconf than specified by AC_PREREQ

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: trunk

[edelsohn (David Edelsohn)]

configure.in states

AC_PREREQ(2.62)

but building with Autoconf-2.64 fails due to missing feature. configure in releases are created using Autoconf-2.69 and that worked on trunk. I do not know the absolute minimum requirement, but 2.62 no longer is correct.

It seems autoconf 2.63 works on CentOS:

Could you show what failures occur?

[edelsohn (David Edelsohn)]

With Autoconf-2.64 I receive the following error:

configure:1510: error: possibly undefined macro: _m4_text_wrap_word
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.

Autoconf-2.69 works.

As far as we know, 2.64 and 2.66 are buggy, so we bumped AC_PRE_REQ to 2.67 (Debian Squeeze uses this) at r40034, thanks.
