A Mysterious Error in Zephyr Configuration

During the configuration of Zephyr, one often encounters inexplicable errors.

the toolchain is unable to build a dummy C file.

Feeling helpless, right? No one to help you?

Solution:

1 Check the CMake version, use the recommended version, and avoid using a version that is too high; if it is too high, uninstall and reinstall.

2 Delete the zephyrproject/zephyr/.cache directory.

If there are still issues, check build/CMakeFiles/CMakeConfigureLog.yaml; any problems will be displayed here.

Remember to install the requirements from zephyr/scripts/requirements.txt, otherwise, you will encounter a lot of ‘no module’ issues, which can be quite overwhelming.

You’re welcome.
