%general-entities; ]> $LastChangedBy$ $Date$ 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. Download (HTTP): Download (FTP): MD5 Sum: &pcre-md5; Download size: &pcre-size; Estimated disk space required: &pcre-buildsize; Estimated build time: &pcre-time; Install PCRE by running the following commands: ./configure --prefix=/usr --enable-utf8 && make && 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 /usr/lib/libpcre.so.* /lib/ && ln -sf ../../lib/libpcre.so.0 /usr/lib/libpcre.so --enable-utf8: This switch includes the code for handling UTF-8 character strings in the library. The PCRE package contains the libpcre libraries, pcregrep, pcretest and pcre-config. pcregrep is a grep that understands Perl compatible regular expressions. pcretest can test your Perl compatible regular expression. pcre-config is used during the compile process of programs linking to this library.
