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

'DoubleSolenoid::DoubleSolenoid()'

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

#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
    }
}
};

Any help would be appreciated.
