Unfortunately, this issue is very custom to your changes and you will have to debug this issue by yourself. Note that ROS integration is not a default on the SDK and we are quite unfamiliar with this error and will need more debug on the specific changes that you have done at your end. -2- And also I was not able to follow that guide: Sorry, what are you not able to follow in this guide? Yes, the SDK is dependent on Ubuntu 14.04 and it is recommended that you use the mentioned version to recreate the SDK successfully. Regards Karthik",
