When I tryp to build gnu-smalltalk with autoconf-2.62 I will get the following error messages: [s4504kr@zeus ~]$ cd cvs/fedora/gnu-smalltalk/F-9/smalltalk-3.0.3/ [s4504kr@zeus smalltalk-3.0.3]$ cd tests/ [s4504kr@zeus tests]$ make /bin/sh /home/s4504kr/cvs/fedora/gnu-smalltalk/F-9/smalltalk-3.0.3/build-aux/missing --run autom4te --language=autotest -I '.' -o testsuite.tmp testsuite.at testsuite.tmp:669: error: possibly undefined macro: m4_if If this token and others are legitimate, please use m4_pattern_allow. See the Autoconf documentation. make: *** [testsuite] Fehler 1 This error occurs only with the version 2.62 of autoconf. Earlier version of autoconf works fine.
reported upstream, fix available at http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=commitdiff_plain;h=3ac7ceb0c2dfd023e0e9e944da6825b6bd676568 Fixed in autoconf-2.62-2
Meanwhile, you may want to file a bug with the gnu-smalltalk package, informing them that they can change their package to work around pristine upstream autoconf 2.62 by altering their offending sequence (something like this): AT_KEYWORDS([m4_if([$1], [dummy], [], [$1 ])dummy]) to instead expand the m4_if prior to invoking AT_KEYWORDS, like this: AT_KEYWORDS(m4_if([$1], [dummy], [], [$1 ])[dummy])
