Error: within this context

[ehlochbr]

I really appreciate both of your replies, but making the corrections you suggested has led me to another problem.

class RobotDemo : public SimpleRobot
{
	RobotDrive myRobot; // robot drive system
	Gamepad controller;
	AxisCamera& camera;
	
public:
	RobotDemo(void):
		myRobot(10, 9, 2, 1),	
		controller(1)
	{                                     <-------------------------ERROR HERE
		GetWatchdog().SetExpiration(0.1);
	
		camera = AxisCamera::GetInstance();  <--------ERROR HERE

The first error says "uninitialized reference". How do I initialize it?
The second error gets me back to where I started. It says "error within this context".

This feels like one step forward then two steps back. Thanks for your help.

You need to initialize all non pointer members before the body (and especially references, they only have one life)

try this:

class RobotDemo : public SimpleRobot
{
	RobotDrive myRobot; // robot drive system
	Gamepad controller;
	AxisCamera& camera;
	
public:
	RobotDemo(void):
		myRobot(10, 9, 2, 1),	
		controller(1),
camera(AxisCamera::GetInstance())
	{                                    
		GetWatchdog().SetExpiration(0.1);

Also, "error within this context" is part of a larger error, open the build console and find the red lines to find the rest of the message. many messages are 2 or more parts.
Ex (bold is error in code)
file.cpp: In constructor `ZomBDashboardPacketSender::ZomBDashboardPacketSen der()':
file.cpp:301: error: uninitialized reference member `ZomBDashboardPacketSender::hp'
WPILib/Dashboard.h:58: error: `void Dashboard::operator=(const Dashboard&)' is private
file.cpp:302: error: within this context
