configure: error: PCRE2 was explicitly referenced but it was not found in v3.0.12 about modsecurity

Hi @samuelzokovich,

thanks for reporting.

First of all, please read about the libmodsecurity3's role here.

As you can see, it's not a webserver's module but it's a library. This means it needs a connector - a webserver module which uses this library and provides functions to the server. There is only one working (open source) connector, for Nginx. Actually, there isn't connector for Apache.

This means you can't use the mentioned configure options, like --with-apr, --with-apu and --with-apxs. This is why your configure reports these as unrecognized options - see above in your report.

If you want to use ModSecurity with Apache, you must choose mod_security2 - actually there is no other option.

Regarding to your PCRE2 issue: libmodsecurity3 uses the "old" PCRE (aka PCRE3) library by default. If you want to build it with PCRE2, please pass the --with-pcre2 configure option.

I'm going to close this issue, because it's not a bug. Feel free to ask anything, if you need any help.

Hello @airween

Thanks for the clarification.

This might be a very silly question but where do I download the mod_security2 from?

Thanks
