Introduction to Pcre

Project Homepage: Unknown

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-8.34/html &&
install -v -m644 doc/html/* /usr/share/doc/pcre-8.34/html &&
install -v -m644 doc/{Tech.Notes,*.txt} /usr/share/doc/pcre-8.34

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/ &&
LIBNAME=$(cat libpcre.la | grep dlname | cut -f2 -d"'" | cut -f1 -d" ")
ln -sf ../../lib/$LIBNAME /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 &&
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/ &&
LIBNAME=$(cat libpcre.la | grep dlname | cut -f2 -d"'" | cut -f1 -d" ") &&
ln -sf ../../lib/$LIBNAME /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/ &&
LIBNAME=$(cat libpcre.la | grep dlname | cut -f2 -d"'" | cut -f1 -d" ") &&
ln -sf ../../lib32/$LIBNAME /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-8.34/html &&
install -v -m644 doc/html/* /usr/share/doc/pcre-8.34/html &&
install -v -m644 doc/{Tech.Notes,*.txt} /usr/share/doc/pcre-8.34
