Linux Host Requirements

• Installed ESP-IDF including all ESP-IDF requirements
• System package requirements (libbsd, libbsd-dev)
• 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 ESP-IDF to the build process which is otherwise done for convenience.
