I made work Gazebo 2 with DRCsim 3.2, I looked and tried versions until it worked. I hope it helps. To remove Gazebo 4 you can use --purge and then install with 'sudo apt-get install ros-indigo-gazebo-ros'.

I am trying to use the unordered_map library, specifically the .emplace function. I can create an instance of an unordered_map, but the compiler generates the error 'class std::unordered_map<mytype, float=""> has no member named 'emplace'.

I had the same problem, one of my friends told me I was missing some linker dependencies to ros::serialization::throwStreamOverrun().

And also that I needed to add the package that contains ros::serialization to the build_dependencies and the run_dependencies in the package.xml and also to the CMakeLists.txt.

In the CMake-file the build_dependencies are in the line that starts with find_package(catkin REQUIRED COMPONENTS and the run_dependencies usually are in the catkin_package( ... block. Also, in the line target_link_libraries(your_executable ${catkin_LIBRARIES}) that belongs to your executable you might need to add the ${catkin_LIBRARIES} if it is not already there.

For me that worked and hope for you also.
