Sounds like you are trying to use the C++ code (I should have thought about it in the last email). I found the problem in src/OI.cpp
frc::SmartDashboard:

utData("Open Claw", new OpenClaw());
frc::SmartDashboard:

utData("Close Claw", new CloseClaw());
Is declared before the dashboard is initialized. You can try commenting them
out, or put them in their own init function.
This seems to get it to not crash, but I'm not getting clean data from the joystick controller, to the system. I'm wondering if the latest code is really functional.
