8.7. Bzip2-1.0.8

8.7.1. Installation of Bzip2

Apply a patch that will install the documentation for this package:

patch -Np1 -i ../bzip2-1.0.8-install_docs-1.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

Compile and test the package:

make

Install the programs:

make PREFIX=/usr install

Install the shared library:

cp -av libbz2.so.* /usr/lib
ln -sfv libbz2.so.1.0.8 /usr/lib/libbz2.so

The name of the shared library isn't standardized and it varies among distros. The instruction above has installed libbz2.so.1.0, but some applications, for example Kbd, expects a different name libbz2.so.1 that some other distros are using. Create a compatibility symlink for them:

ln -sfv libbz2.so.1.0.8 /usr/lib/libbz2.so.1

Note

The symlink approach is only valid here because the library name difference is a result of different aesthetic views of the distro maintainers, not real ABI incompatibilities. In general a library name difference most likely indicates an ABI incompatibility and it would be very likely invalid to “hide” the difference via a symlink. Read Section 8.2.1, “Upgrade Issues” for details about library names.

Install the shared bzip2 binary into the /usr/bin directory, and replace two copies of bzip2 with symlinks:

cp -v bzip2-shared /usr/bin/bzip2
for i in /usr/bin/{bzcat,bunzip2}; do
  ln -sfv bzip2 $i
done

Remove a useless static library:

rm -fv /usr/lib/libbz2.a

8.7.2. Installation of Bzip2 - 32-bit

Clean previous build:

make clean
make -f Makefile-libbz2_so clean

Compile the package:

sed -e "s/^CC=.*/CC=gcc -m32/" -i Makefile{,-libbz2_so}
make -f Makefile-libbz2_so

Install the package:

install -Dm755 libbz2.so.1.0.8 /usr/lib32/libbz2.so.1.0.8
ln -svf libbz2.so.1.0.8 /usr/lib32/libbz2.so
ln -svf libbz2.so.1.0.8 /usr/lib32/libbz2.so.1
ln -svf libbz2.so.1.0.8 /usr/lib32/libbz2.so.1.0
