That macro is using a questionable technique to accomplish this (parsing
the output of perl -v and then relying on AX_COMPARE_VERSION). Here's a
much simpler macro that accomplishes the same thing:
AC_DEFUN([AX_PROG_PERL_VERSION],
[AC_CACHE_CHECK([for Perl version $1 or later], [ax_cv_prog_perl_version],
[AS_IF(["$PERL" -e 'require $1;' >/dev/null 2>&1], [$1], [$2])])])
Thank you. I don't know whether there is a typo here, or perhaps I am
calling it incorrectly - which is the same way as I called the original
macro.
checking how to run the C preprocessor... gcc -E
checking for perl... /usr/local/bin/perl
checking for Perl version 5.8.0 or later... ./configure: line 4685: 5.8.0:
command not found
That's an odd error message, since it implies that the single quotes
around require $1 are missing. What's line 4685 of your configure file?
on line 4685 there is:
5.8.0
Here's are a few lines either side of it:
# Be more Bourne compatible
DUALCASE=1; export DUALCASE # for MKS sh
if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then
