Introduction to PCRE2

The PCRE2 package contains a new generation of the Perl Compatible Regular Expression libraries. These are useful for implementing regular expression pattern matching using the same syntax and semantics as Perl.

本パッケージは LFS-8.1 において正しくビルドでき動作することが確認されています。

Installation of PCRE2

Install PCRE2 by running the following commands:

./configure --prefix=/usr                       \
            --docdir=/usr/share/doc/pcre2-10.30 \
            --enable-unicode                    \
            --enable-pcre2-16                   \
            --enable-pcre2-32                   \
            --enable-pcre2grep-libz             \
            --enable-pcre2grep-libbz2           \
            --enable-pcre2test-libreadline      \
            --disable-static                    &&
make

To test the results, issue: make check.

Now, as the root user:

make install

Command Explanations

--enable-unicode: This switch enables Unicode support and includes the functions for handling UTF-8/16/32 character strings in the library.

--enable-pcre2-16: This switch enables 16 bit character support.

--enable-pcre2-32: This switch enables 32 bit character support.

--enable-pcre2grep-libz: This switch adds support for reading .gz compressed files to pcre2grep.

--enable-pcre2grep-libbz2: This switch adds support for reading .bz2 compressed files to pcre2grep.

--enable-pcre2test-libreadline: This switch adds line editing and history features to the pcre2test program.

--disable-static: このスイッチはスタティックライブラリをインストールしないようにします。

--enable-jit: this option enables Just-in-time compiling, which can greatly speed up pattern matching.
