These are useful for implementing regular expression pattern matching using the same syntax and semantics as Perl 5. &lfs79_checked; Package Information Download (HTTP): Download (FTP): Download MD5 sum: &pcre-md5sum; Download size: &pcre-size; Estimated disk space required: &pcre-buildsize; Estimated build time: &pcre-time; PCRE Dependencies Optional User Notes: Install PCRE by running the following commands: ./configure --prefix=/usr \ --docdir=/usr/share/doc/pcre-&pcre-version; \ --enable-unicode-properties \ --enable-pcre16 \ --enable-pcre32 \ --enable-pcregrep-libz \ --enable-pcregrep-libbz2 \ --enable-pcretest-libreadline \ --disable-static && make To test the results, issue: make check. Now, as the root user: make install && mv -v /usr/lib/libpcre.so.* /lib && ln -sfv ../../lib/$(readlink /usr/lib/libpcre.so) /usr/lib/libpcre.so --enable-unicode-properties: This switch enables Unicode properties support and includes the code for handling UTF-8/16/32 character strings in the library. You need this switch if you are going to build with the --with-pcre=system switch. --enable-pcre16: This switch enables 16 bit character support. --enable-pcre32: This switch enables 32 bit character support. --enable-pcregrep-libz: This switch adds support to pcregrep to read .gz compressed files. --enable-pcregrep-libbz2: This switch adds support to pcregrep to read .bz2 compressed files. --enable-pcretest-libreadline: This switch adds line editing and history features to pcretest program. mv -v /usr/lib/libpcre.so.* /lib: Moves the PCRE library on the root filesystem so that it is available in case grep gets reinstalled with PCRE support.
