* GNU Make 3.82 or a build tool that CMake supports.
* A C99 toolchain (compiler, linker, archiver). We actively test with GCC 5.4, Clang 3.8, Arm Compiler 6, IAR 8 and Visual Studio 2017. More recent versions should work. Slightly older versions may work.
* If cross-compiling, and not using an official release, a C compiler for the build platform. Set the `HOSTCC` environment variable to this compiler.
* Python 3.8 to generate the test code. Python is also needed to integrate PSA drivers and to build the development branch (see next section).
* Perl to run the tests, and to generate some source files in the development branch.
* CMake 3.10.2 or later (if using CMake).

Depending on your Python installation, you may need to invoke `python` instead of `python3`. To install the packages system-wide, omit the `--user` option.
* A C compiler for the host platform, for some test data.

If you are cross-compiling, you must set the `CC` environment variable to a C compiler for the host platform when generating the configuration-independent files.
If you are cross-compiling, you must set the `HOSTCC` environment variable to a C compiler for the host platform when generating the configuration-independent files. If `HOSTCC` is unset, `CC` will be used instead.

Any of the following methods are available to generate the configuration-independent files:
