Chapter 6. Installing Basic System Software

6.56. Xz-5.2.1

The Xz package contains programs for compressing and decompressing files. It provides capabilities for the lzma and the newer xz compression formats. Compressing text files with xz yields a better compression percentage than with the traditional gzip or bzip2 commands.

Approximate build time: 0.4 SBU
Required disk space: 22 MB

6.56.1. Installation of Xz

6.56.2. 32-bit Installation

Prepare Xz for 32-bit compilation with: 

./configure --prefix=/usr        \
--docdir=/usr/share/doc/xz-5.2.1 \
--libdir=/usr/lib32              \
CC="gcc -m32"

Compile the package: 

make

To test the results, issue: 

make check

Install the package and make sure that all essential files are in the correct directory: 

make install
mv -v   /usr/bin/{lzma,unlzma,lzcat,xz,unxz,xzcat} /bin
mv -v /usr/lib32/liblzma.so.* /lib32
ln -svf ../../lib32/$(readlink /usr/lib32/liblzma.so) /usr/lib32/liblzma.so

Clean up the build directory before moving on to the next platform: 

make clean

6.56.3. x32 ABI Installation

Prepare Xz for x32 ABI compilation with: 

./configure --prefix=/usr        \
--docdir=/usr/share/doc/xz-5.2.1 \
--libdir=/usr/libx32             \
CC="gcc -mx32"

Compile the package: 

make

To test the results, issue: 

make check

Install the package and make sure that all essential files are in the correct directory: 

make install
mv -v   /usr/bin/{lzma,unlzma,lzcat,xz,unxz,xzcat} /bin
mv -v /usr/libx32/liblzma.so.* /libx32
ln -svf ../../libx32/$(readlink /usr/libx32/liblzma.so) /usr/libx32/liblzma.so

Clean up the build directory before moving on to the next platform: 

make clean

6.56.4. 64-bit Installation

Prepare Xz for 64-bit compilation with: 

./configure --prefix=/usr --docdir=/usr/share/doc/xz-5.2.1

Compile the package: 

make

To test the results, issue: 

make check

Install the package and make sure that all essential files are in the correct directory: 

make install
mv -v   /usr/bin/{lzma,unlzma,lzcat,xz,unxz,xzcat} /bin
mv -v /usr/lib/liblzma.so.* /lib
ln -svf ../../lib/$(readlink /usr/lib/liblzma.so) /usr/lib/liblzma.so
