Introduction to PCRE

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.

Dependencies

Non-Multilib

Configure and compile the package:

./configure --prefix=/usr --enable-utf8 &&
make

Install the package:

make install &&
install -v -m755 -d /usr/share/doc/pcre-6.7/html &&
install -v -m644 doc/html/* /usr/share/doc/pcre-6.7/html &&
install -v -m644 doc/{Tech.Notes,*.txt} /usr/share/doc/pcre-6.7

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 -v -sf ../../lib/libpcre.so.0 /usr/lib/libpcre.so

Multilib

32Bit

Configure and compile the package:

CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" ./configure --prefix=/usr --enable-utf8 &&
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 -v -sf ../../lib/libpcre.so.0 /usr/lib/libpcre.so

N32

Configure and compile the package:

CC="gcc ${BUILDN32}" CXX="g++ ${BUILDN32}" ./configure --prefix=/usr --enable-utf8 --libdir=/usr/lib32 &&
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 -v -sf ../../lib32/libpcre.so.0 /usr/lib32/libpcre.so

64Bit

Configure and compile the package:

CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" ./configure --prefix=/usr --enable-utf8 --libdir=/usr/lib64 &&
make

Install the package:

make install &&
mv -v /usr/bin/pcre-config{,-64} &&
ln -s multiarch_wrapper /usr/bin/pcre-config &&
install -v -m755 -d /usr/share/doc/pcre-6.7/html &&
install -v -m644 doc/html/* /usr/share/doc/pcre-6.7/html &&
install -v -m644 doc/{Tech.Notes,*.txt} /usr/share/doc/pcre-6.7

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