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
The meaning of the make parameter:
-
-f
Makefile-libbz2_so
-
This 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 and test the package:
make
Install the programs:
make PREFIX=/usr install
Install the shared library:
cp -av libbz2.so.* /usr/lib
ln -sv 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 -sv libbz2.so.1.0.8 /usr/lib/libbz2.so.1
![[Note]](../images/note.png)
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 - 32bit
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 -sf libbz2.so.1.0.8 /usr/lib32/libbz2.so
ln -sf libbz2.so.1.0.8 /usr/lib32/libbz2.so.1
