# 8.6. Zlib-1.2.11

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

Approximate build time: less than 0.1 SBU
Required disk space: 5.0 MB

## 8.6.1. Installation of Zlib

Prepare Zlib for compilation:

    ./configure --prefix=/usr

Compile the package:

    make

To test the results, issue:

    make check

Install the package:

    make install

The shared library needs to be moved to `/lib`, and as a result the `.so` file in `/usr/lib` will need to be recreated:

    mv -v /usr/lib/libz.so.* /lib
    ln -sfv ../../lib/$(readlink /usr/lib/libz.so) /usr/lib/libz.so

Remove an useless static library:

    rm -fv /usr/lib/libz.a

## 8.6.2. Contents of Zlib

Installed libraries: libz.so
