<title>Installation of Bzip2</title>

<para>Install Bzip2 by running the following commands:</para>

<para><screen><userinput>make -f Makefile-libbz2_so &amp;&amp;
make &amp;&amp;
rm /usr/bin/bz* &amp;&amp;
make PREFIX=/usr install &amp;&amp;
cp bzip2-shared /bin/bzip2 &amp;&amp;
ln -s libbz2.so.1.0 libbz2.so &amp;&amp;
cp -a libbz2.so* /lib &amp;&amp;
ln -sf ../../lib/libbz2.so /usr/lib&amp;&amp;
rm /usr/bin/{bunzip2,bzcat,bzip2} &amp;&amp;
rm /bin/{bzless,bzmore} &amp;&amp;
mv /usr/bin/{bzip2recover,bzless,bzmore} /bin &amp;&amp;

ln -sf bzip2 /bin/bzcat</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>
