The example in https://github.com/nrfconnect/sdk-nrf/blob/v2.0.0/samples/bluetooth/throughput/CMakeLists.txt#L14-L18 did it!

Thanks!

UPDATE: I noticed after submitting this answer, that the person replying was different from the person behind the initial post. But I think I (and Wayne) have answered the questions from the initial post as well

Yes, you need to add the .c files to CMakeLists.txt. I'm not aware of any ways to do it through the GUI.

A trick is to add the following to the CMakeLists.txt: https://github.com/nrfconnect/sdk-nrf/blob/v2.0.0/samples/bluetooth/throughput/CMakeLists.txt#L14-L18

Then all the .c files in src will automatically get included in the build.

[quote user="flaik-wayne"]I just watched some of the walkthrough videos - in video 3 https://youtu.be/3yi6kuxgdPg he mentions doing a pristine build if you have edited CMakeLists.txt or the application configuration files.[/quote]

Actually, it seems like it is enough to run a normal build after editing CMakeLists. I tried modifying the CMakeList.txt and built the app and got this result:

Building hello_world
west build --build-dir c:\v2.0.0\zephyr\samples\hello_world\build_53 c:\v2.0.0\zephyr\samples\hello_world

[0/1] Re-running CMake...
.
.
.
.
.

So it seems like the cmake changes are detected, and it will re-run cmake. I think the same applies if you modify Kconfigs (e.g. prj.conf) or the Device tree (.overlay files), the changes will be detected and cmake wil re-run.

A pristine build directory is essentially a new build directory. All byproducts from previous builds have been removed. As mentioned here.

I don't know exactly how west works in details and in what circumstances it wil re-run cmake or not, but I can ask internally if you would like a more certain answer.

Learn more about west build/pristine builds here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/zephyr/guides/west/build-flash-debug.html#pristine-builds

Take a look at the page below to learn about the build and configuration phase:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.1/zephyr/guides/build/index.html

In short the configuration phase wil run cmake and go through the dts/dts/.overlay files, Kconfig files and generate the build system. The build phase will run ninja (similar to make) and generate the .hex/.elf files. If you only modify .h/.c files, it is only the build phase that will run.

Best regards,

Simon
