I just tried to run a configure script
generated by the CVS version of autoconf.
% ~/project/tkgs/configure
configure: error: cannot run
This was caused by a check for config.sub
the file did not exist in my src tree.
This is a problem, but the test is also
broken because the AC_CONFIG_AUX_DIR_DEFAULT
seems to be getting expanded after the
AC_CANONICAL_BUILD macro. The result
is the following in the generated configure.
(line 699)
# Make sure we can run config.sub.
$ac_config_sub sun4 >/dev/null 2>&1 ||
{ echo "configure: error: cannot run config.sub = $ac_config_sub" >&2;
exit 1; }
(line 816)
if test -z "$ac_aux_dir"; then
{ echo "configure: error: cannot find install-sh or install.sh in
$srcdir $srcdir/.. $srcdir/../.." >&2; exit 1; }
fi
ac_config_guess="$SHELL $ac_aux_dir/config.guess"
ac_config_sub="$SHELL $ac_aux_dir/config.sub"
ac_configure="$SHELL $ac_aux_dir/configure" # This should be Cygnus
configure.
The ac_config_sub is getting set after it is getting used
(inside the AC_CANONICAL_BUILD macro).
Here is what the defs in acgeneral look like:
# AC_CANONICAL_BUILD

I am stumped. Is something wrong with the
AC_REQUIRE([AC_CONFIG_AUX_DIR_DEFAULT]) such
that is no longer includes the text from
AC_CONFIG_AUX_DIR_DEFAULT?
