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
        )

        Yes, when omit BYPASS_IDL, I'll meet build error too.

        So Nordic do not support ZAP auto generate(omit BYPASS_IDL) in the build flow? And user must use zap tool to generate files manually?

Hi Chuan,

It can work by following the steps in one of my previous replies. I got it to work on both Windows and Linux.

For installing zap-cli, you might have to use python instead of python3:

python scripts/setup/nrfconnect/get_zap.py -l <location_path> -o

However, the recommended method is to generate the ZAP tools manually using the west zap generate command.

Best regards,
Marte

        Great!

        I'll have a try to use 'python' instead of 'python3'.

        Besides, can you build light bulb pass even though omit 'BYPASS_IDL'?

Hi Chuan,

Yes, I was able to build the light bulb sample on both Windows and Linux when omitting BYPASS_IDL by including the path to the light_bulb.matter IDL file in chip_configure_data_model():

IDL ${CMAKE_CURRENT_SOURCE_DIR}/src/light_bulb.matter

Please note that I have not thoroughly tested the sample, only that it builds.

Best regards,
Marte

        Thanks for your solution, it work well!

        Finally, I have another question：

        I see there are 9 files in the zap-generated folder, namely: 

                -> access.h

                -> callback-stub.cpp

                -> CHIPClientCallbacks.h

                -> CHIPClusters.h

                -> endpoint_config.h

                -> gen_config.h

                -> gen_tokens.h

                -> IMClusterCommandHandler.cpp

                -> PluginApplicationCallbacks.h

         But when I use ZCL tool to generate files, only 4 files generate, namely:

                -> access.h

                -> endpoint_config.h

                -> gen_config.h

                -> IMClusterCommandHandler.cpp

        Can you tell me why cause this difference?

        Besides, how can I generate other 5 files?
