'msr::airlib::RealMultirotorConnector' is an abstract class

[jeremyfix]

When running build.sh , an error is thrown because 'msr::airlib::RealMultirotorConnector' is an abstract class. Indeed, the following two virtual pure methods are not overriden :

virtual bool setSegmentationObjectID(const std::string& mesh_name, int object_id,
bool is_name_regex = false) = 0;

virtual int getSegmentationObjectID(const std::string& mesh_name) = 0;

in the file AirSim/AirLib/include/vehicles/multirotor/controllers/RealMultirotorConnector.hpp and it inherits from AirSim/AirLib/include/controllers/VehicleConnectorBase.hpp

I succeed in building AirSim, by simply defining these two methods in RealMultirotorConnector.hpp with an empty body , but I do not know if this the expected behavior.

I had the same error, did what you did and it worked for me. I'm not sure what effect this will have though.

Thanks for reporting this. This is now fixed.

The problem still seems to persist; this time complaining about the following virtual function that is not implemented in RealMultirotorConnector.hpp:

virtual void printLogMessage(const std::string& message, std::string message_param = "", unsigned char severity = 0)

Temporarily adding that function to RealMultirotorConnector.hpp with an empty body solves the build problem, but a more principled solution is needed.
