nRF connect SDK fails to build with "attempt to assign the value 'y' to the undefined symbol"

[jeremyherbert]

Hi,

Just reporting an issue I am having with the nRF9160 SDK in the hope that it will help someone else. OS is Ubuntu 18.04.

I was getting errors which look like this:

/home/jeremy/nrfconnect/ncs/nrf/samples/nrf9160/https_client/prj.conf:2: warning: attempt to assign the value 'y' to the undefined symbol BSD_LIBRARY

/home/jeremy/nrfconnect/ncs/nrf/samples/nrf9160/https_client/prj.conf:3: warning: attempt to assign the value 'n' to the undefined symbol BSD_LIBRARY_SYS_INIT

/home/jeremy/nrfconnect/ncs/nrf/samples/nrf9160/https_client/prj.conf:12: warning: attempt to assign the value 'y' to the undefined symbol MODEM_KEY_MGMT

/home/jeremy/nrfconnect/ncs/nrf/samples/nrf9160/https_client/prj.conf:13: warning: attempt to assign the value 'y' to the undefined symbol LTE_LINK_CONTROL

and these were preventing the build from completing. The issue here is that the nRF connect setup asks you to install the pip libraries using the --user flag, which will put everything in ~/.local/bin. However, this path is not part of the default PATH environment variable. Adding this to the path in Segger Embedded Studio (or CLion in my case) is what fixed the problem.

Hi.

You should select the non-secure version of the board, as bsdlib can only be used from a non-secure application and you need bsdlib to use the modem.

To select the non-secure version of the board, you must select the version with "ns" at the end of the name, e.g. nrf9160_pca10090ns.

Best regards,

Didrik

As far as I can tell, I had selected the “ns” version of the board. But if this was the issue, then why did changing the python path work?

[Didrik Rokhaug]

From my experience, the errors you got indicates that you did not select the non-secure version of the board.

As for why changing the python path worked, you either selected the non-secure version of the board after changing the path, or you had a different root problem.
