Unable to generate compile commands in OpenThread CLI Example

[AustinE]

I recently got the nRF52840DK and have been able to build/flash a couple simple samples. However when attempting to try the OpenThread CLI example on tool chain v1.6.1 and v1.7.0 there seems to be an issue generating the "compile_commands.json". After poking around I was unable to determine why this is happening and tried deleting and recreating the sample a couple times. Tweaking the build config gave the same result seen below. Did I miss something in the documentation on running thread examples?

Hello, 

There is an issue with paths i.e. [PATH]/otcli/../common/overlay-ot-defaults.conf which we are aware of. I will forward this to the developers and get back to you with a work-around.

Kind regards,
Øyvind

A follow-up to my previous comment. What is [PATH] configured to? Where is the project folder located? You have also pulled in config files for nRF5340 in the build command: [PATH]/otcli/prj_nrf5340dk_nrf5340_cpuapp.conf

"[PATH]" is the path to where the sample was saved. For me /Users/<username>/git/nrf/otcli/prj...

[Øyvind]

Hello, 

Can you please elaborate on how you are building the project? Are you using command line or the VS Code extension? I'm very curious to why it executes west build with -DCONF_FILE:STRING=[PATH]/otcli/prj_nrf5340dk_nrf5340_cpuapp.conf when you are building for board --board nrf52840dk_nrf52840

Kind regards,
Øyvind

Hello,

I'm currently using the VS code extension. I believe I set that profile(or what that config is called) but the normal "proj.conf" didn't work either.

I am having the same issue. Here is the VCS plugin screen when configuring the project. This is with SDK v1.7.0 on a Mac
