6.53. XZ-Utils-4.999.8beta

The XZ-Utils package contains programs for compressing and decompressing files. Compressing text files with XZ-Utils yields a much better compression percentage than with the traditional gzip.

6.53.1. Environment Settings

This package requires compiler variables to be set for the target in the environment. 

export CC="${CLFS_TARGET}-gcc"
export CXX="${CLFS_TARGET}-g++"
export AR="${CLFS_TARGET}-ar"
export AS="${CLFS_TARGET}-as"
export RANLIB="${CLFS_TARGET}-ranlib"
export LD="${CLFS_TARGET}-ld"
export STRIP="${CLFS_TARGET}-strip"

6.53.2. Installation of XZ-Utils

Prepare XZ-Utils for compilation: 

./configure --build=${CLFS_HOST} --host=${CLFS_TARGET} \
    --prefix=/usr

Compile the package: 

make

Install the programs: 

make DESTDIR=${CLFS} install

Move the xz binary, and several symlinks that point to it, into the /bin directory: 

mv -v ${CLFS}/usr/bin/{xz,lzma,lzcat,unlzma,unxz,xzcat} ${CLFS}/bin
