Can not build sample bluetooth\peripheral_lbs from Linux nrf connect sdk: undefined symbols

[Philippe OReilly]

Hi,

I am trying to build the bluetooth sample peripheral_lbs from the nrfconnect sdk. I get the following errors:

/home/newtrax/workspace/sdk-nrf/samples/bluetooth/peripheral_lbs/prj.conf:6: warning: attempt to assign the value 'y' to the undefined symbol NCS_SAMPLES_DEFAULTS

/home/newtrax/workspace/sdk-nrf/samples/bluetooth/peripheral_lbs/prj.conf:13: warning: attempt to assign the value 'y' to the undefined symbol BT_LBS

/home/newtrax/workspace/sdk-nrf/samples/bluetooth/peripheral_lbs/prj.conf:14: warning: attempt to assign the value 'y' to the undefined symbol BT_LBS_POLL_BUTTON

/home/newtrax/workspace/sdk-nrf/samples/bluetooth/peripheral_lbs/prj.conf:15: warning: attempt to assign the value 'y' to the undefined symbol DK_LIBRARY

My build command is :

west build  -b nrf5340dk_nrf5340_cpuapp .

My nrf connect sdk version is 1.7.99

Has anyone encountered (and solved) the same problem ?

Hey Phillipe!

Have you tried any other samples, and do you get a similar errors on those?

I assume you installed NSC using the Getting Started Assistant?

Best regards,

Hi Elfving,

I did not run the Getting Started Assistant, because I want to build using west under Linux (Ubuntu 18.04), while the Assistant requires to build within Segger Studio (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_assistant.html#getting-started-assistant).

Some samples are building, while other don't. The applications using the BT_XXXX configuration parameters are the ones that are failing to build.

Hey again Phillipe,

I see. Its not an error I have seen before. Do you get the same error on an official release? Eg. NCS 1.8.0 or 1.7?

And do you get it if you build it for a single core SoC, eg. the nRF52833?

Best regards,

Elfving

Hi Elfving

I installed NCS 1.8.0 and got rid of the error. I was able to compile with the nrf52833 target board.

Thank you very much

Philippe
