10.33. Zlib-1.2.3 32 Bit Libraries

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

10.33.1. 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:

CC="gcc ${BUILD32}" CXX="g++ ${BUILD32}" ./configure --prefix=/usr \
   --shared

Compile the package:

make

To test the results, issue: make check.

Install the package:

make install

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

Details on this package are located in Section 10.35.2, “Contents of Zlib.”
