Introduction to Pcre
...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 && 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/ && 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++ ${BUILD64}" ./configure --prefix=/usr --enable-utf8 --libdir=/usr/lib64 &&
make
Install the package:
make install &&
mv -v /usr/bin/pcre-config{,-64} &&
ln -s multiarch_wrapper /usr/bin/pcre-config
If you reinstall Grep after installing PCRE, Grep will get linked against PCRE and may cause problems if /usr is a separate mount point. To avoid this, either pass the option --disable-perl-regexp when executing ./configure for Grep or move libpcre to /lib as follows.
mv -v /usr/lib64/libpcre.so.* /lib64/ && LIBNAME=$(cat libpcre.la | grep dlname | cut -f2 -d"'" | cut -f1 -d" ") && ln -sf ../../lib64/$LIBNAME /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. |
