On 2005-05-20, at_top_builddir, a variable `configure' passes to `testsuite' via `atconfig', changed names to at_top_build_prefix. Consequently, `configure' generated by `autoconf' predating the change do not properly configure `testsuite' generated by `autom4te' postdating the change, and vice-versa. With the manifest breakage, `testsuite' treats its suite as freestanding and so does not augment PATH. The suite therefore tests already-installed copies of the subject programs instead of the copies the user just built. This especially touches Autoconf, since we always build `testsuite' with the new `autom4te', but Automake's `configure' update rule uses `autoconf' from one's PATH. It will affect developers of other packages using Autotest when they rebuild `configure' with a different `autoconf' without also rebuilding their test suite. We could avoid subtle breakage by encoding a version number in `atconfig' and `testsuite' and comparing them. Is there an easier/better way? In the mean time, be sure to install a post-2005-05-20 Autoconf before rebuilding Autoconf's `configure'. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
