Build Matter Light Bulb using ZAP auto generated files dynamically

        Sorry for the inconvenience!

        I have downloaded V2.8.0 nRF SDK, and I use this command to build light bulb project:

        west build -p always --build-dir nrf/samples/matter/light_bulb/build -b nrf52840dk_nrf52840 nrf/samples/matter/light_bulb

        It can build pass! But I noticed that bulb project used zap generated files, I want to auto generate zap files in the build flow(that means generating code files by light_bulb.zap dynamically), could you tell me how can I do?

        Furthermore, I have noticed the macro("BYPASS_IDL") in cmake file is TRUE, so it skip auto generate flow, how can I set it to FALSE?

        chip_configure_data_model(app
               INCLUDE_SERVER
               BYPASS_IDL
               GEN_DIR ${CONFIG_NCS_SAMPLE_MATTER_ZAP_FILES_PATH}/zap-generated
               ZAP_FILE ${CMAKE_CURRENT_SOURCE_DIR}/${CONFIG_NCS_SAMPLE_MATTER_ZAP_FILES_PATH}/light_bulb.zap
        )

Hi Chuan,

I asked the developers about this, and it looks like the files you mentioned were generated with an older version of the ZAP tool and are no longer used. The developers will remove the old files from the SDK.

The developers have also added a --clear argument to zap-generate that removes old files: https://github.com/nrfconnect/sdk-connectedhomeip/pull/599.

Best regards,
Marte

        Sorry to bother you again: What do old files mean?

Hi Chuan,

Some files in the SDK samples were generated with an older version of the ZAP tool, and they are no longer needed, which is why they are not generated when running the ZAP tool in later versions. Since they are no longer needed, they will be removed from the samples.

You can see which files are removed in this commit: https://github.com/nrfconnect/sdk-nrf/commit/22789834d870df307b414d0ddf0dc801541684ca

Best regards,
Marte
