Bzip2-&bzip2-version; Bzip2 <para>The Bzip2 package contains programs for compressing and decompressing files. Compressing text files with <command>bzip2</command> yields a much better compression percentage than with the traditional <command>gzip</command>.</para> <segmentedlist> <segtitle>&buildtime;</segtitle> <segtitle>&diskspace;</segtitle> <seglistitem> <seg>&bzip2-ch6-sbu;</seg> <seg>&bzip2-ch6-du;</seg> </seglistitem> </segmentedlist> </sect2> <sect2 role="installation"> <title>Installation of Bzip2 Apply a patch that will install the documentation for this package: patch -Np1 -i ../&bzip2-docs-patch; The following command ensures installation of symbolic links are relative: sed -i 's@\(ln -s -f \)$(PREFIX)/bin/@\1@' Makefile Ensure the man pages are installed into the correct location: sed -i "s@(PREFIX)/man@(PREFIX)/share/man@g" Makefile Prepare Bzip2 for compilation with: make -f Makefile-libbz2_so make clean The meaning of the make parameter: -f Makefile-libbz2_so This will cause Bzip2 to be built using a different Makefile file, in this case the Makefile-libbz2_so file, which creates a dynamic libbz2.so library and links the Bzip2 utilities against it. Compile and test the package: make Install the programs: make PREFIX=/usr install Install the shared bzip2 binary into the /bin directory, make some necessary symbolic links, and clean up: cp -v bzip2-shared /bin/bzip2 cp -av libbz2.so* /lib ln -sv ../../lib/libbz2.so.1.0 $LFS/usr/lib/libbz2.so rm -v /usr/bin/{bunzip2,bzcat,bzip2} ln -sv bzip2 /bin/bunzip2 ln -sv bzip2 /bin/bzcat Contents of Bzip2 Installed programs Installed libraries Installed directory bunzip2 (link to bzip2), bzcat (link to bzip2), bzcmp (link to bzdiff), bzdiff, bzegrep (link to bzgrep), bzfgrep (link to bzgrep), bzgrep, bzip2, bzip2recover, bzless (link to bzmore), and bzmore libbz2.{a,so} /usr/share/doc/bzip2-&bzip2-version; Short Descriptions bunzip2 Decompresses bzipped files bunzip2 bzcat Decompresses to standard output bzcat bzcmp Runs cmp on bzipped files bzcmp bzdiff Runs diff on bzipped files bzdiff bzegrep Runs egrep on bzipped files bzegrep bzfgrep Runs fgrep on bzipped files bzfgrep bzgrep Runs grep on bzipped files bzgrep bzip2 Compresses files using the Burrows-Wheeler block sorting text compression algorithm with Huffman coding; the compression rate is better than that achieved by more conventional compressors using Lempel-Ziv algorithms, like gzip bzip2 bzip2recover Tries to recover data from damaged bzipped files bzip2recover bzless Runs less on bzipped files bzless bzmore Runs more on bzipped files bzmore libbz2 The library implementing lossless, block-sorting data compression, using the Burrows-Wheeler algorithm libbz2
