Build Matter Light Bulb using ZAP auto generated files dynamically

[susepc]

 devzone 

        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,

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?

The zap files are generated with the "west zap generate" command. You cannot combine this and the west build command into one, but you can create a script that runs both commands.

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?

You can omit BYPASS_IDL from chip_configure_data_model, and it should not bypass it.

Best regards,
Marte

        Thanks for your support!

        I have omit BYPASS_IDL as blow:

chip_configure_data_model(app
               INCLUDE_SERVER
               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
        )

        But meet build error:

ninja: error: '../../src/default_zap/light_bulb.matter', needed by 'gen/app-codegen/cpp-app/app/PluginApplicationCallbacks.h', missing and no known rule to make it
[11/23] Generating new Factory Data...

FAILED: _sysbuild/sysbuild/images/light_bulb-prefix/src/light_bulb-stamp/light_bulb-build

        Can you have a try? If the same case, could you please tell me the reason and how to fix this error?
