The PCRE2 package contains a new generation of the Perl Compatible Regular Expression libraries. These are useful for implementing regular expression pattern matching using the same syntax and semantics as Perl.
This package is known to build and work properly using an LFS-10.1 platform.

Install PCRE2 by running the following commands:
./configure --prefix=/usr \ --docdir=/usr/share/doc/pcre2-10.36 \ --enable-unicode \ --enable-jit \ --enable-pcre2-16 \ --enable-pcre2-32 \ --enable-pcre2grep-libz \ --enable-pcre2grep-libbz2 \ --enable-pcre2test-libreadline \ --disable-static && make
To test the results, issue: make check.
Now, as the root
user:
make install
