PCRE (Perl Compatible Regular Expressions) is a lightweight Perl function library, including a perl-Compatible Regular Expression Library. It is much smaller than the regular expression library such as Boost. PCRE is very easy to use and has powerful functions. Its performance exceeds the POSIX Regular Expression Library and some classic Regular Expression Libraries.

3. Go to the/pcre-8.40 directory, run./configure for Initialization Configuration, print a bunch of information, if the following prompt appears, because the C ++ compiler is missing.

If openssl is not installed before executing the preceding command, the following message is displayed:

./Configure: error: SSL modules require the OpenSSL library.

In this case, run yum-y install openssl-devel. After openssl is installed, the above operations can be performed smoothly)
