Introduction to Pcre

PCRE is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5.

Project Homepage: http://www.pcre.org

Dependencies

Non-Multilib

Configure and compile the package: 

./configure --prefix=/usr \
    --enable-utf8 --enable-unicode-properties \
    --enable-pcregrep-libz  --enable-pcregrep-libbz2 \
    --enable-pcretest-libreadline --enable-pcre32 --enable-pcre16 &&
make


Install the package: 

make install

If you reinstall Grep after installing PCRE, Grep will get linked against PCRE and may cause problems if /usr is a separate mount point. To avoid this, either pass the option --disable-perl-regexp when executing ./configure for Grep or move libpcre to /lib as follows. 

mv -v /usr/lib/libpcre.so.* /lib/ &&
ln -svf ../../lib/libpcre.so.0 /usr/lib/libpcre.so

Command Explanations

--enable-utf8: This switch includes the code for handling UTF-8 character strings in the library.

Multilib

32Bit

Configure and compile the package: 

CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" \
./configure --prefix=/usr --enable-utf8 --enable-unicode-properties \
    --enable-pcregrep-libz  --enable-pcregrep-libbz2 \
    --enable-pcretest-libreadline --enable-pcre32 --enable-pcre16 &&
make

Install the package: 

make install &&
mv -v /usr/bin/pcre-config{,-32}

If you reinstall Grep after installing PCRE, Grep will get linked against PCRE and may cause problems if /usr is a separate mount point. To avoid this, either pass the option --disable-perl-regexp when executing ./configure for Grep or move libpcre to /lib as follows. 

mv -v /usr/lib/libpcre.so.* /lib/ &&
ln -svf ../../lib/libpcre.so.0 /usr/lib/libpcre.so

N32

Configure and compile the package: 

CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" \
./configure --prefix=/usr --libdir=/usr/lib32 \
    --enable-utf8 --enable-unicode-properties \
    --enable-pcregrep-libz  --enable-pcregrep-libbz2 \
    --enable-pcretest-libreadline --enable-pcre32 --enable-pcre16 &&
make

Install the package: 

make install &&
mv -v /usr/bin/pcre-config{,-n32}

If you reinstall Grep after installing PCRE, Grep will get linked against PCRE and may cause problems if /usr is a separate mount point. To avoid this, either pass the option --disable-perl-regexp when executing ./configure for Grep or move libpcre to /lib as follows. 

mv -v /usr/lib32/libpcre.so.* /lib32/ &&
ln -svf ../../lib32/libpcre.so.0 /usr/lib32/libpcre.so

64Bit

Configure and compile the package: 

CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" ./configure \
--prefix=/usr --libdir=/usr/lib64 \
    --enable-utf8 --enable-unicode-properties \
    --enable-pcregrep-libz  --enable-pcregrep-libbz2 \
    --enable-pcretest-libreadline --enable-pcre32 --enable-pcre16 &&
make

Install the package: 

make install &&
mv -v /usr/bin/pcre-config{,-64} &&
ln -s multiarch_wrapper /usr/bin/pcre-config

If you reinstall Grep after installing PCRE, Grep will get linked against PCRE and may cause problems if /usr is a separate mount point. To avoid this, either pass the option --disable-perl-regexp when executing ./configure for Grep or move libpcre to /lib64 as follows. 

mv -v /usr/lib64/libpcre.so.* /lib64/ &&
ln -svf ../../lib64/libpcre.so.0 /usr/lib64/libpcre.so

Contents

Installed Programs: pcregrep, pcretest, and pcre-config
Installed Libraries: libpcre.{so,a}, libpcrecpp.{so,a} and libpcreposix.{so,a}
Installed Directories: /usr/share/doc/pcre

Short Descriptions

pcregrep is a grep that understands Perl compatible regular expressions.
pcretest can test a Perl compatible regular expression.
pcre-config is used during the compile process of programs linking to the PCRE libraries.
