Eclipse WPILib Problem C++

[BrianAtlanta]

This isn't likely not be related, but thought I would mention this C++ driver station update just in case.

Note that I am attempting to answer this question having not looked at the WPILib in several years...

The error you are describing sounds like you are trying to instantiate an interface rather than a fully implemented class. Posting a code snipit might help diagnose the exact problem. Do you have a line in your code like:

SpeedController sc = new SpeedController();

or

SpeedController sc = new IVictorSP();

If so, try replacing it with something like:

SpeedController sc = new VictorSP();

Basically what seems to be happening is that there exists a class "SpeedController" that has a method "Set" that is not implemented (it is pure virtual), making this class be an interface. Other classes, such as Victor, Tallon, etc, will derive from the SpeedController class and must implement the Set() method. The error you are reporting makes it sound like you are trying to instantiate one of the parent classes/interfaces, rather than the child class that actually has the implementation.

Check your documentation and make sure you are instantiating the correct class.

Do you at least see an FRCUserProgram binary under the Binaries tree node in the Project explorer? If so then your code is building ok, in which case the IDE parser is likely showing stale info. In which case this should fix it....

Then in the project explorer, under binaries delete your FRCUserProgram. This step is necessary just for checking that the project does build.

We are getting stuck at this part. Where would we find the binaries to find the FRCUserProgram?

Look at the eclipse screenshots. There is a tree node called "Binaries" in the project explorer. It's above "Includes", which is above "Debug", etc...
