nRF Connect for VS Code YouTube videos, having problems with Include paths and Kconfig in mac OS

[alwalker]

 am following the introductory videos and have done a fresh install of the Toolchain, Segger, VS Connect 3.7.2, nRF Connect SDK v1.8.0 and VS code on macOS 

1. Installation

https://www.youtube.com/watch?v=2cv_jjqk5hg&list=PLx_tBuQ_KSqEt7NK-H7Lu78lT2OijwIMl

2. Create an application

https://www.youtube.com/watch?v=KwJtcPZHV30&list=PLx_tBuQ_KSqEt7NK-H7Lu78lT2OijwIMl&index=2

3. Building an application & Exploring windows

https://www.youtube.com/watch?v=3yi6kuxgdPg&list=PLx_tBuQ_KSqEt7NK-H7Lu78lT2OijwIMl&index=3

The source code shows errors with the paths for the INCLUDE statements:

This is the output from the Terminal window:

Using macOS Finder to locate the individual header files, Seem to have found the first one ok but not the others:

What should the paths be for the other header files please?

Note that in macOS the /opt folder is normally hidden.

When I do a Pristine Build, this is what is displayed in Terminal:

There also doesn't look to be a Kconfig file selected, this is not mentioned in the three YouTube videos:

 

Any guidance is very welcome!

Hi,

This should work out of the box. Can you try to build from the command line initially, to simplify things initially? Please open the toolchain manager, click the downwards error to the right of v1.8.0 and select "Open Terminal". Then do the following:

cd zephyr/samples/basic/blinky
west build -b nrf5340dk_nrf5340_cpuapp --pristine

That should build without any issues. Does it? For reference, it looks like this on my Mac:

➜  v1.8.0 cd zephyr/samples/basic/blinky
➜  blinky git:(c932ad1952) west build -b nrf5340dk_nrf5340_cpuapp --pristine

If not, can you let me know which Mac model you have and which macOS version you are using? Also, as you say there are missing files (though I did not see any direct indication of that in the errors here), it could be worth trying to re-install the toolchain from the toolchain manager. We have seen issues in the past where repositories are not completely checked out, and unfortunately the error handling in the toolchain manager is quite sparse at the moment, so in such cases checkout may fail silently.

this is what I get from using the macOS Terminal using "Open Terminal" form the Toolchain Manager:

It's not a case of missing files, rather that the Kconfig file can't be located and whilst the C header files exist, where they are put in the macOS file system is not colocated with the Workspace folder.

[alwalker]

As it seems that there is a CMake error, this is what I have installed:

This is the Toolchain folder structure:

[Einar Thorsrud]

I see you use Catalina. I don't know of any specific reason it should not work, but we only do release testing with the latest macOS. So there could be something there. It does not seem likely though, as the error is this (for reference):

/opt/nordic/ncs/v1.8.0/zephyr/scripts/kconfig/kconfig.py: samples/basic/blinky/build/Kconfig/Kconfig.modules:38: Could not open '/opt/nordic/ncs/v1.8.0/zephyr/' (in 'osource "$(ZEPHYR_MCUBOOT_KCONFIG)"') (EISDIR: Is a directory)

CMake Error at /opt/nordic/ncs/v1.8.0/zephyr/cmake/kconfig.cmake:270 (message):

  command failed with return code: 1

And the exact same error is reported from Cmake in this old thread. It does not seem it ever got resolved, though.

I did not get this? But in any case, I really suggest we skip VSCode (if that is what you refer to by workspace), as this issue is clearly not related to it as you also reproduce it by using west directly. The fewer variables in the mix, the better.

As I currently don't see anything sticking out, I want to just check another idea which sometimes cause issues on macOS. Which filesystem do you have?
