5.7. Installing Bzip2-1.0.2

Estimated build time:           1 minute
Estimated required disk space:  3 MB

5.7.1. Installation of Bzip2

Install Bzip2 by running the following commands:

make CC="gcc -static" &&
make PREFIX=$LFS/usr install &&
cd $LFS/usr/bin &&
mv bzcat bunzip2 bzip2 bzip2recover bzless bzmore $LFS/bin

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 installed.

5.7.2. Command explanations

make CC="gcc -static": This is the method we use to tell gcc that we want bzip2 to be linked statically.
