About
-----

`Zlib`_ is designed to be a free, general-purpose, and lossless data-compression library.

.. note:: If you are a software developer, consider moving to :doc:`zlib-ng`.

Supported versions
------------------

To check which zlib versions and build types are currently supported on Discoverer, execute on the login node:

.. code-block:: bash

 module avail zlib

The recipe followed to build the source code is available at:

https://gitlab.discoverer.bg/vkolev/recipes/-/tree/main/zlib

There you may also find the log files with the messages generated during the configuration, compilation, testing, and installation of the package.

Loading/Compiler affinity
-------------------------

Each version of zlib installed in the public software repository is built against five compiler sets: (i) :doc:`llvm`, (ii) :doc:`oneapi`, (iii) :doc:`nvidia_hpc_sdk`, (iv) :doc:`aocc`, (v) :doc:`gcc`. The name of the environmental module contains the name of the compiler set employed for compiling the zlib source code.
