Error building lwm2m_client

Dominik Windhab

Hi!

I am currently trying to build the lwm2m_client. Currently I am using ncs v1.1.0-rc3.

I am using the devkit as hardware. The only thing I changed in the proj.conf is CONFIG_LWM2M_PEER_PORT and CONFIG_APP_LWM2M_SERVER.

Building with "west build -b nrf9160_pca10090 -d build_nrf9160_pca10090" leads to the following error:

../src/lwm2m/lwm2m_button.c: In function 'handle_button_events':
../src/lwm2m/lwm2m_button.c:32:23: error: operator '>' has no left operand
 #if CONFIG_FLIP_INPUT > 0
                       ^

[33/443] Building C object CMakeFiles/app.dir/src/lwm2m/lwm2m_light_control.c.obj

Do I have to define the #define for CONFIG_FLIP_INPUT manually?

    Hi.

    First, NCS v1.1.0 was just released. You should use that, not the release candidate.

    Secondly, the lwm2m_client sample and any other application that uses the modem must be built as non-secure. Could you try to change the board name to nrf9160_pca10090ns (notice the "ns" at the end)?

    When changing board, you must also clean the build directory. Either delete it (or all its content) or add the "-p" flag to west.

    Best regards,

    Didrik
