You quote a from-scratch build with configure being an order of magnitude slower than parallel compilation. But one just 35 seconds long. Granted, configure time does add up if one builds 10s of packages in sequence. Is there some reason configure caches are unsuitable to gain speedup there? I see almost a six-fold configure improvement on grep-2.20 when its working from a config.cache. That brings configure to 140% of parallel compilation, but we're talking an overall build like 6 seconds. - Rhys _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
