<title>Installation of Bzip2</title>
<para>Install Bzip2 by running the following commands:</para>
<para><screen><userinput>make -f Makefile-libbz2_so &&</userinput>
<userinput>make bzip2recover libbz2.a &&</userinput>
<userinput>cp bzip2-shared /bin/bzip2 &&</userinput>
<userinput>cp bzip2recover /bin &&</userinput>
<userinput>cp bzip2.1 /usr/share/man/man1 &&</userinput>
<userinput>cp bzlib.h /usr/include &&</userinput>
<userinput>cp -a libbz2.so* /lib &&</userinput>
<userinput>rm /usr/lib/libbz2.a &&</userinput>
<userinput>cp libbz2.a /usr/lib &&</userinput>
<userinput>cd /usr/lib &&</userinput>
<userinput>ln -sf ../../lib/libbz2.so &&</userinput>
<userinput>cd /bin &&</userinput>
<userinput>ln -sf bzip2 bunzip2 &&</userinput>
<userinput>ln -sf bzip2 bzcat &&</userinput>
<userinput>cd /usr/share/man/man1 &&</userinput>
<userinput>ln -sf bzip2.1 bunzip2.1 &&</userinput>
<userinput>ln -sf bzip2.1 bzcat.1 &&</userinput>
<userinput>ln -sf bzip2.1 bzip2recover.1</userinput></screen></para>
<para>Although it's not strictly a part of a basic LFS system it's worth
mentioning that a patch for Tar can be downloaded which enables the tar
program to compress and uncompress using bzip2/bunzip2 easily. With a
plain tar, you have to use constructions like bzcat file.tar.bz|tar
xv or tar --use-compress-prog=bunzip2 -xvf file.tar.bz2 to use bzip2 and
bunzip2 with tar. This patch provides the -j option so you can unpack a
Bzip2 archive with tar xvfj file.tar.bz2. Applying this patch will be
mentioned later on when the Tar package is re-installed.</para>
