These are useful for implementing regular expression pattern matching using the same syntax and semantics as Perl 5. Package information Download (HTTP): Download (FTP): Download MD5 Sum: &pcre-md5; Download size: &pcre-size; Estimated disk space required: &pcre-buildsize; Estimated build time: &pcre-time; Installation of <application><acronym>PCRE</acronym></application> Install PCRE by running the following commands: ./configure --prefix=/usr --enable-utf8 && make Now, as the root user: 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 -v -sf ../../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.
