Chief Delphi - Double Solenoid Function Error

We're trying to use several double solenoids in C++, but we keep getting an error. no matching function for call to

Code:

'DoubleSolenoid::DoubleSolenoid()'

Here's the code we're trying to use:

Code:

#include "WPILib.h"

class Robot: public SampleRobot {

Joystick driver;

DoubleSolenoid shootingArm;

DoubleSolenoid shifter;

DoubleSolenoid pusher;



const double kUpdatePeriod = 0.005;



// Numbers of the buttons to use for triggering the solenoids.

const int kSolenoidButton = 4;

const int kDoubleSolenoidForward = 2;

const int kDoubleSolenoidReverse = 3;



public:

Robot() :

        driver(0), // Use joystick on port 0.

        // Use double solenoid with Forward Channel of 1 and Reverse         of 2.

        shootingArm(1, 2)

{

}



void OperatorControl()

{

    while (IsOperatorControl() && IsEnabled())

    {

        if (driver.GetRawButton(kDoubleSolenoidForward))

            shootingArm.Set(DoubleSolenoid::kForward);

        else if (driver.GetRawButton(kDoubleSolenoidReverse))

            shootingArm.Set(DoubleSolenoid::kReverse);

        else

            shootingArm.Set(DoubleSolenoid::kOff);



        Wait(kUpdatePeriod);                // wait for a motor update time

    }

}

};



START_ROBOT_CLASS(Robot)

Any help would be appreciated.
