Hi Jacob, The guess was the two most probable locations: /usr/share/autoconf and /usr/local/share/autoconf.
Wouldn't have worked on my own system :). Challenge accepted. Thanks! if $PERL -I${autom4te_perllibdir:-$(sed -n \ '/autom4te_perllibdir/{s/^.*|| //;s/;$//;s/^.//;s/.$//;p;q}' \ <$(command -v autom4te))} -MAutom4te::FileUtils \ -e 'exit defined $INC{q[Time/HiRes.pm]} ? 0 : 1'; then # autom4te uses Time::HiRes unfortunately we are highly restricted in what we can use in basic automake/conf shell code (as opposed to in the tests). Neither the "command" command nor $(...) syntax can be used. For the former, I think there's an autoconf/make macro to look up a program name along PATH? For the latter, good old `...` suffices. (Not sure there can be newlines in `...` though, even backslashed.) Would you be up for tweaking the check to use such least-common-denominator shell stuff? Ordinarily Perl could not be used either, but since Automake is written in Perl, I don't see a problem with doing so here. (If the system doesn't have Perl, Automake won't get far.) Not sure if $PERL is already defined by the time at which this would be run, but it should be possible to arrange with an ac prerequisite if needed. Thanks, Karl
