Grep:this version of PCRE isn't compiled with PCRE_UTF8 support

Objective:

The company server has a problem after the migration, and when grep uses regular expressions, it always prompts grep:this version of PCRE is not compiled with Pcre_utf8 Support,pcre as a function library of regular expressions. Make it annoying if you don't correct it. I am the source of the installation. So when recompiling, add the option to support Utf-8.

Steps:

(1) Uninstalling Prce

If it is RPM package, Direct Rpm-qa | grep prce or Rpm-e pcre--nodeps on it, I use the source package compiled installation.

[Email protected] pcre]# Cd/pcre

[email protected] pcre]# make Uninstall

(2) See what options are available for uts-8 support

[Email protected] pcre]# Cd/pcre

[Email protected] pcre]#/configure--help

(3) Recompile

[Email protected] pcre]#/configure--enable-utf8

[[email protected] pcre]# make && make install

(4) Verification

This is not the time to add

This is recompiled and will not show that line again
