Please check. Thanks. Previous Comments: ------------------------------------------------------------------------ [2018-04-24 21:41:34] cmb@php.net Thanks – re-opening. Actually, there are even further issues at least with the version detection[1]; $pcre_version is "210222" for me (PCRE 10.22) due to the 2 in PCRE2. > checking for pcre2_jit_exec in -lpcre2... no For some reason, pcre-jit seems to be supported for the bundled libpcre2 only[2].

Since PHP requires the 8-bit version[2], we'd have to change (or extend?) the respective check[3]: test -f $j/libpcre2-8.a || test -f $j/libpcre2-8.$SHLIB_SUFFIX_NAME && PCRE_LIBDIR=$j [1] <https://packages.debian.org/sid/i386/libpcre2-dev/filelist> [2] <https://github.com/php/php-src/blob/703e0370905bc432aa26d71803b3081851e99230/ext/pcre/config0.m4#L58> [3] <https://github.com/php/php-src/blob/703e0370905bc432aa26d71803b3081851e99230/ext/pcre/config0.m4#L27> ------------------------------------------------------------------------ [2018-04-23 18:27:03] pprkut at slackware dot com Description: ------------ Configure doesn't work when building with --with-pcre-regex=/usr: checking for PCRE headers location... /usr/include checking for PCRE library location... configure: error: Could not find libpcre2.(a|so) in /usr The problem is that there is no libpcre2.so on my system (slackware linux). I have these options: /usr/lib64/libpcre2-16.so /usr/lib64/libpcre2-32.so /usr/lib64/libpcre2-8.so /usr/lib64/libpcre2-posix.so I checked arch and fedora and libpcre2.so doesn't appear to be a thing there either. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76256&edit=1
