6.39.4.

6.39.5. Installation of Bzip2

Prepare Bzip2 for compilation with:

make -f Makefile-libbz2_so
make clean

The -f flag 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 the package:

make

Install it:

make install

And install the shared bzip2 binary into the /bin directory, then make some necessary symbolic links, and clean up:

cp bzip2-shared /bin/bzip2
cp -a libbz2.so* /lib
ln -s ../../lib/libbz2.so.1.0 /usr/lib/libbz2.so
rm /usr/bin/{bunzip2,bzcat,bzip2}
mv /usr/bin/{bzip2recover,bzless,bzmore} /bin
ln -s bzip2 /bin/bunzip2
ln -s bzip2 /bin/bzcat
