- A recent enough Linux or MacOS version and gcc compiler
- All components the application depends on must be either supported on the Linux target (Linux/POSIX simulator) or mock-able
An application that runs on the Linux target has to set the ``COMPONENTS`` variable to ``main`` in the CMakeLists.txt of the application's root directory:
..code-block:: cmake
set(COMPONENTS main)
This prevents the automatic inclusion of all components from IDF to the build process which is otherwise done for convenience.
