Installation of PCRE
Install PCRE by running the following commands:
./configure --prefix=/usr \
--docdir=/usr/share/doc/pcre-8.33 \
--enable-unicode-properties \
--enable-pcre16 \
--enable-pcre32 \
--enable-pcregrep-libz \
--enable-pcregrep-libbz2 \
--enable-pcretest-libreadline \
--disable-static &&
make
To test the results, issue: make check.
Now, as the root user:
make install && mv -v /usr/lib/libpcre.so.* /lib && ln -sfv ../../lib/$(readlink /usr/lib/libpcre.so) /usr/lib/libpcre.so
Command Explanations
--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-2.38.0 with the --with-pcre=system switch.
--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.
mv -v /usr/lib/libpcre.so.* /lib: Moves the PCRE library on the root filesystem so that it is available in case grep gets reinstalled with PCRE support.
