lvgl sample code build is not working

bilal7317

I am trying to build basic LVGL code and it is giving me the following error. I did not customize the code.

https://github.com/nrfconnect/sdk-zephyr/tree/v3.4.99-ncs1-rc2/samples/subsys/display/lvgl/

    Hi,

    Which command did you use to build the sample?

    Regards,

    I have tried both but still getting the same error:

    Building lvgl
    C:\Windows\system32\cmd.exe /d /s /c "west build --build-dir d:/nrf/test_proj/test/lvgl/build d:/nrf/test_proj/test/lvgl"

    I was also able to see the following message if it is of any use:

    Our DKs does not have a display enabled in the devicetree by default.

    If you add a display as a shield to this example, it should build:

    I have used the following command and I was able to build it successfully.

    C:\Windows\system32\cmd.exe /d /s /c "west build --build-dir d:/nrf/test_proj/test/lvgl/build d:/nrf/test_proj/test/lvgl --pristine --board nrf52840dk_nrf52840 -- -DSHIELD=adafruit_2_8_tft_touch_v2"

    Thanks a lot for the guidance.
    Now you can close the ticket.

      Now I want to build it for nrf52832 but I am getting the following error:
