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