Previous Comments: ------------------------------------------------------------------------ [2021-07-06 16:16:16] cmb@php.net Is this still unresolved for any of the actively supported PHP versions[1]? If so, I suggest you provide a PR[2] for better visibility.

For this, tiny C programms are just-in-time compiled and then defines are set. This does not work well when cross-compiling as we do for OpenWrt for example: we could try to successfully compile the programm, but it is not possible to actually run it. So without further modification this leads to a php binary/opcache addon which does not have _any_ shared memory implementation compiled in, and it results in errors like this one: https://github.com/openwrt/packages/issues/1010 Maybe it possible to not rely the detection on such run-during-compile tests? I'm no autoconf expert, but I wonder whether there is a possibility to "preseed" the test results? To make it work for OpenWrt, we hacked a patch which simply checks for one important function used by one SHM implementation or the other. But this might not be sufficient. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69657&edit=1
