C++-Bindings - Example does not run

[kschoos]

After installing all the prerequisites and trying to run the random_agent.cpp in
cpp bindings, it threw an Error, saying it cannot convert a certain value to float.
Changing from Breakout-v0 to CartPole-v0 made it work for the time being.

@kschoos how did you compile and run the C++ example?
I'm unable to compile (OSX 10.14):

$ g++ -o gym_exec random_agent.cpp -I include/gym/
Undefined symbols for architecture x86_64:
  "Gym::client_create(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, int)", referenced from:

Found an old makefile here.

The implementation does not support 3D states, i.e., image inputs. You need to call Breakout-ram-v0.
