Linux From Scratch - Version 8.3-rc2

Chapter 6. Installing Basic System Software

6.45. Xz-5.2.4

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: 0.2 SBU
Required disk space: 16 MB

6.45.1. Installation of Xz

Prepare Xz for compilation with: 

./configure --prefix=/usr    \
            --disable-static \
            --docdir=/usr/share/doc/xz-5.2.4

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
