In php 8.0.x, I already noticed a similar problem with just the opcache extension and I applied a workaround in MacPorts that adds a compatibility implementation of these functions via the MacPorts "legacy support" library. Here's our implementation: https://github.com/macports/macports-legacy-support/blob/master/include/time.h https://github.com/macports/macports-legacy-support/blob/master/src/time.c But now in php 8.1.x the build failure affects php as a whole. We don't have a compatibility implementation of clock_gettime_nsec_np in MacPorts legacy support yet (https://trac.macports.org/ticket/61691) so we are not able to work around it by adding our library here. Looks like this problem was caused in php commit a3e55286a676fdf4f5919d219e2a0df93f817211 ("Using a more modern and simpler api available since Sierra (2016).") Since you had an apparently working implementation before, perhaps you can have a configure test that checks for clock_gettime, uses it if available, and otherwise uses the older implementation. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81137&edit=1
