The main system used for development is CMake. That system is always the most up-to-date. The others should reflect all changes present in the CMake build system, but some features are not ported there by default.
Make
----
We intentionally only use the absolute minimum of **Make** functionality, as we have discovered that a lot of **Make** features are not supported on all different implementations of Make on different platforms. As such, the Makefiles sometimes require some handwork or `export` statements in order to work for your platform.
Depending on your platform, you might run into some issues. Please check the Makefiles in *library/*, *programs/* and *tests/* for options to manually add or remove for specific platforms. You can also check `the PolarSSL Knowledge Base <https://polarssl.org/kb>`_ for articles on your platform or issue.
In case you find that you need to do something else as well, please let us know what, so we can add it to the KB.
The workspace 'polarssl.dsw' contains all the basic projects needed to build the library and all the programs. The files in tests are not generated and compiled, as these need a perl environment as well.
Example programs
================
We've included example programs for a lot of different features and uses in *programs/*. Most programs only focus on a single feature or usage scenario, so keep that in mind when copying parts of the code.
PolarSSL includes an elaborate test suite in *tests/* that initially requires Perl to generate the tests files (e.g. *test_suite_mpi.c*). These files are generates from a **function file** (e.g. *suites/test_suite_mpi.function*) and a **data file** (e.g. *suites/test_suite_mpi.data*). The **function file** contains the template for each test function. The **data file** contains the test cases, specified as parameters that should be pushed into a template function.
Configurations
==============
We provide some non-standard configurations focused on specific use cases in the configs/ directory. You can read more about those in configs/README.txt
We graciously accept bugs and contributions from the community. There are some requirements we need to fulfil in order to be able to integrate contributions in the main code.
Simple bug fixes to existing code do not contain copyright themselves and we can integrate those without any issue. The same goes for trivial contributions.
For larger contributions, e.g. a new feature, the code possible falls under copyright law. We then need your consent to share in the ownership of the copyright. We have a form for that, which we will mail to you in case you submit a contribution or pull request that we deem this necessary for.
