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:
To test the results, issue: make check.
Install the package:
The previous command installed a .so file in /usr/lib. We will move it into /lib and then relink it to /usr/lib:
mv -v /usr/lib/libz.so.* /lib ln -svf ../../lib/libz.so.1 /usr/lib/libz.so
Now we fix the permissions on the static library:
chmod -v 644 /usr/lib/libz.a
