Issue Description
Hello @SivaRamaKrishnaNV
After converting the dwCamerNode in c++ using dw::framework::ExceptionSafeSensorNode Class there is a missing header file error in dwCameraNodeImpl.hpp which is of as follows
include <dwframework/dwnodes/sensors/dwsensornode/impl/dwSensorNodeImpl.hpp>.

I’ve seen that there is no path related to this in docker.

Can you please guide us what this error is?

Regards,
Prit

Dear @prit.shah,
The requested header files of dwSensorNode is not shipped in DRIVE OS release.
As I understand, you have used nodestub.py tool to generate cpp files from dwCameraNode.json. If you want to use any supported sensor, you can directly use its corresponding sensor node.json in your application.

dear @SivaRamaKrishnaNV since the header files arent shipped with the DRIVE OS; however using the nodestub.py with dw::framework::ExceptionSafeSensorNode class for the camera application’s CameraNode.node.json mentions the directory for framework’s sensor node implementation header file:

#define DW_FRAMEWORK_DWCAMERANODEIMPL_HPP_

#include <dwcgf/node/SimpleNodeT.hpp>
#include <dwframework/dwnodes/sensors/dwsensornode/impl/dwSensorNodeImpl.hpp>

#include "./dwCameraNode.hpp"

#include <dw/core/base/Types.h>
#include <dw/image/Image.h>
#include <dwframework/dwnodes/common/SelfCalibrationTypes.hpp>
#include <dwframework/dwnodes/common/SensorCommonTypes.hpp>

  1. Does this mean that the class used with nodestub.py is to be set for only dw:framework::ExceptionSafeProcessNode on DRIVE OS 6.0.8.1?

  2. As of now I understand, to make a custom application we need to create the stubs from the custom made application’s nodes from the graphlet.json and then add logic integration on the process functions of the implementation cpp files?

  3. If the above is true, do let me know what is causing the build fail.

regards,
Prit

Dear @SivaRamaKrishnaNV , just a friendly reminder

Dear @prit.shah,
Yes. you are correct. When you use ExceptionSafeSensorNode, it is adding few files which are not part of devzone release and hence causing build issues. Please use only ProcessNode with nodestub.py to create stub files of a process node.

Dear @SivaRamaKrishnaNV ,
Thank you
