The PCRE package contains Perl Compatible Regular Expression libraries. These are useful for implementing regular expression pattern matching using the same syntax and semantics as Perl 5.
This package is known to build and work properly using an LFS 11.3 platform.

Install PCRE by running the following commands:
./configure --prefix=/usr \
--docdir=/usr/share/doc/pcre-8.45 \
--enable-unicode-properties \
--enable-pcre16 \
--enable-pcre32 \
--enable-pcregrep-libz \
--enable-pcregrep-libbz2 \
--enable-pcretest-libreadline \
--disable-static &&
makeTo test the results, issue: make check.
Now, as the root user:
make install
--enable-unicode-properties: This switch enables
Unicode properties support and includes the code for handling UTF-8/16/32
character strings in the library. You need this switch if you are going to
build GLib-2.74.5.
--enable-pcre16: This switch enables 16 bit
character support.
--enable-pcre32: This switch enables 32 bit
character support.
--enable-pcregrep-libz: This switch adds
support to pcregrep to read
.gz compressed files.
--enable-pcregrep-libbz2: This switch adds
support to pcregrep to read
.bz2 compressed files.
--enable-pcretest-libreadline: This switch adds line
editing and history features to pcretest program.
--disable-static: This switch prevents
installation of static versions of the libraries.
--enable-jit: this option enables Just-in-time
compiling, which can greatly speed up pattern matching.
