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
