6.18. Zlib-1.2.3

The Zlib package contains compression and decompression routines used by some programs.

6.18.1. Installation of Zlib

This patch will add -fPIC to our build and allow us to build a static and shared library at the same time:

patch -Np1 -i ../zlib-1.2.3-fPIC-1.patch

Prepare Zlib for compilation:

./configure --prefix=/usr --shared

Compile the package:

make AR="${AR} rc"

Install the pacakge:

make prefix=${CLFS}/usr install

The previous command installed a .so file in ${CLFS}/usr/lib. We will move it into ${CLFS}/lib and then relink it to ${CLFS}/usr/lib:

mv -v ${CLFS}/usr/lib/libz.so.* ${CLFS}/lib
ln -svf ../../lib/libz.so.1 ${CLFS}/usr/lib/libz.so

Now we fix the permissions on the static library:

chmod -v 644 ${CLFS}/usr/lib/libz.a
