> Upgraded to pcre2 10.39 from pcre1 8.45 (Changelog) > > For third-party modules (like mod_security) that cannot build > > with pcre2, pcre.dll is in /bin That looks like the changelog from the apachelounge build for Windows. I don't think it applies to your personal build. > Does it mean 2.4.53 will work only with PCRE2 modules and no more supporting PCRE 8.xx version? No. You choose at compilation time. > We are also compiling mod_security along with 2.4.53, what additional steps we need to perform with pcre2. Check their doc/community. > I would also like to know which file is pointing/referring to libpcre2-8.so.0 module while starting the instance is it apachectl or httpd.conf? The binaries themselves most likely. You can see with "ldd" on unix or "depends.exe" on Windows. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
