Chapter 6. Cross Compiling Temporary Tools

6.16. Xz-5.6.2

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: 0.1 SBU
Required disk space: 20 MB

6.16.1. Installation of Xz

Prepare Xz for compilation: 

./configure --prefix=/usr                     \
            --host=$LFS_TGT                   \
            --build=$(build-aux/config.guess) \
            --disable-static                  \
            FILECMD=file                      \
            --docdir=/usr/share/doc/xz-5.6.2

The meaning of the new configure options:

ac_cv_prog_FILECMD=file

Works around an issue in the shipped libtool copy causing the configure script fail to find the file command of the host distro. The issue is harmless for most architectures, but it can make --disable-static ineffective for MIPS.

Compile the package: 

make

Install the package: 

make DESTDIR=$LFS install

Remove the libtool archive file because it is harmful for cross compilation: 

rm -v $LFS/usr/lib/liblzma.la
