'FromProto' was not declared in this scope

I was trying to convert isaac msgs to ROS msgs, how to solve this error?

If you haven’t seen this already, here’s a useful related doc: ROS Bridge — ISAAC 2020.2 documentation

As for this particular issues, FromProto is a convention for producing the runtime object from a proto (see 2020.2/sdk/messages/math.hpp for examples).

Have you checked that you are including all of the appropriate headers? Could you provide some context as to where you are seeing this error?

@hemals : Thanks , able to solve the issue.
