Build matter sample FAILED on newest NCS SDK 2.7.0

[Aaron]

Hi,

In VS code,

I created a new application by "copy a sample", the path is C:\ncs\v2.7.0\projects\light_bulb, and the build process failed.

But the build process is successful if I build the sample directly in the original folder C:\ncs\v2.7.0\nrf\samples\matter\light_bulb.

This build problem does not happen on SDK 2.6.1.

Best regards,

Aaron Deng

Hi Aaron,

If you are using VS Code to do building configuration. Please make sure "Use sysbuild" option is checked.

It is stated in nRF Connect SDK v2.7.0 Release Notes (nordicsemi.com):

All samples and applications in the SDK are built with sysbuild by default. Applications that are outside the SDK are not built with sysbuild by default. 

Best regards,

Charlie

Hi Charlie,

Thank you for the response,
After checking the option 'sysbuild', the build process is successful.

Another question, where is the boundary of SDK?
My project is located at "ncs\v2.7.0\projects", is it outside the SDK?

I do not think so. You can verify sysbuild from building log, "sysbuild_default" is the keyword when sysbuild is used.

Building matter_lock
west build --build-dir /opt/nordic/ncs/v2.7.0/nrf/matter_lock/build /opt/nordic/ncs/v2.7.0/nrf/matter_lock --pristine --board nrf5340dk/nrf5340/cpuapp -- -DNCS_TOOLCHAIN_VERSION=NONE

I think inside the SDK means nrf folder. You can find the following definition in nrf/CMakeLists.txt

zephyr_get(NCS_RUNNER_${runner_ext} SYSBUILD)
