nRF Connect SDK build error

[NickH]

Hi,

I am trying to configure the nRF Connect SDK on a Mac running Catalina for the first time and have followed the nRf Connect v3.6.0 - Getting Started Assistant.

I am getting errors when running "pip3 install -r zephyr/scripts/requirements.txt"

ERROR: nrfutil 5.2.0 has requirement click~=7.0, but you'll have click 6.7 which is incompatible.

ERROR: nrfutil 5.2.0 has requirement pyyaml~=4.2b1, but you'll have pyyaml 5.3.1 which is incompatible.

I am not sure how to resolve these dependency errors.

When I complete the SDK installation, it verifies each step with no errors but when I launch the SES (Nordic Edition) V5.10d with a nRF5340 PDK connected, I get a build error:

File "/Users/nick/Development/NordicConnectSDK/ncs/zephyr/scripts/dts/gen_defines.py", line 29, in <module>    import edtlib

File "/Users/nick/Development/NordicConnectSDK/ncs/zephyr/scripts/dts/edtlib.py", line 78, in <module>     import yaml

ModuleNotFoundError: No module named 'yaml'

The yaml module is in "/usr/local/lib/python3.7/site-packages/yaml" and the $PATH includes "/usr/local/lib/python3.7/site-packages".

I'm not sure if the pyyaml dependency error running the requirements script is related to this build error but I I would welcome any suggestions as I can't get past this point and build any of the sample apps.

Thanks!

Hi, Nick!

Could you try to apply the fix Ian has proposed for a similar issue? I.e, comment out line 44 and 45 of the <ncs_root>/zephyr/cmake/python.cmake file like so:

#find_package(Python3 ${PYTHON_MINIMUM_REQUIRED} REQUIRED ${PYTHON_EXACT})
#set(PYTHON_EXECUTABLE ${Python3_EXECUTABLE})

Please report back if this works for you or not!

And thank you for reaching out. We are aware that the installation procedure for MacOS is not currently satisfactory.

Best regards,
Carl Richard

Carl,

Thanks for the quick response - I’ve been trying to solve this for several days now as I’m trying to decide whether to port my code from SDK17 to NRF Connect…

I tried commenting out the line and opening Blinky sample for the 5340 PDK board I have - it got further but still failed.

I haven’t looked in any of the cmake logs mentioned yet. I get the same error with Hello World as well.

Great to hear that it works now! 

When it comes to the issue with nrfx.h, could you try to do the following:
- check if the file <ncs_root>\modules\hal\nordic\nrfx\nrfx.h exists.
- run the command west update inside the NCS root directory.

Report back if it doesn't work.

For adding additional files to your project, check out my answer in this thread. 

Best regards,

I ran west as instructed and re-started SES but same error.

nrfx.h is located at /Users/nick/Development/NordicConnectSDK/ncs/modules/hal/nordic/nrfx

The project is an unmodified blinky sample app.

Ok. Did you open the project with the "Clean Build Directory" option? If not, try that.

I get the same error in blinky and hello world sample apps.  Tried clean build directory option, restarting SES etc...

I see. I'm quite unsure regarding what may be causing this. While I can't manage to reproduce it, I believe it may be related to the YAML issue of earlier. However, you could try to add the nrfx.h file manually (Project -> Add existing file)  and ensure that it's correctly set in menuconfig (Project -> Configure nRF Connect SDK project -> Search for HAS_nRFX).

In addition, could you also post a screenshot of how the nRF Connect SDK is configured in SES. You can find this under Tools -> Options -> nRF Connect SDK.

We've just updated the Toolchain Manager of nRF Connect for Desktop to be more stable for MacOS users, so I recommend trying that if the above is unsuccessfull. 

Best regards,
Carl Richard
