There is an error during make command complaining about pcre2.h file not found

root@kuba-VirtualBox:/home/kuba/event-driven-servers# git log -n 1 --oneline

====================================================================================================================================================================================================
Development files were not found for: LIB-ARES, LIB-CRYPTO, LIB-CURL, LIB-FREERADIUS, LIB-PAM, LIB-SCTP, LIB-SSL, LIB-TLS, LIB-ZLIB

Development files were found for: LIB-CRYPT, LIB-PCRE2

The file

    build/Makefile.inc.linux-5.19.0-50-generic-x86_64

was left unchanged. You may run "make" now. After that, you may wish to do a "make install". Alternatively, you'll find the compiled binaries (plus some ancillary scripts) in the

    build/linux-5.19.0-50-generic-x86_64/fakeroot/

directory structure. It's probably advisable to have a look there in any case, as you may or may not like the particular file system layout, and this will give you a chance to see it before 
installing.

Hi,

PCRE2 support is usually auto-detected (but comes close to mandatory anyway). Perhaps you configured "--with-pcre2", but don't have the PCRE2 development files installed.

Cheers,

Marc

I most probably don't have those. I wasn't aware this have to be installed separately.

What are the steps to do that? Can this be added to documentaion?

MarcJHuber commented

Hi,

installation depends on your Linux distribution. Ubuntu: "apt install libpcre2-dev". I don't remember what the install command is for other setups, but that should be trivial for you to find out, especially as the package name is likely similar.

The prerequisites are actually already documented in PREREQUISITES.txt.

Cheers,

Marc
