On macOS, following the instructions in the docs pointed to here, I get cmake errors running lfc:

Thanks for the report. Will look at it now

This might be due to a mismatch between the Zephyr version you are using (v3.4.0) and the SDK version you have installed (v0.16.3).

My docs in the handbook have not been explicit enough on exactly which versions to install. I am currently working on doing an update to Zephyr v3.7.0 which uses SDK v0.16.8. Will notify when this is ready and you can test it out on your macbook.

Update:

This appears to be a bug in the Zephyr CMake system which arise only on macOS when there is a file/folder named version in the root of the project. I have filed an issue with Zephyr here: zephyrproject-rtos/zephyr#78501
