Question

我正在尝试创建我的swerveDrive，但遇到一个问题，即构造函数与参数列表不匹配。

我已经尝试过上课并更改原本要求的参数。

GenericEnclosure.h

class GenericEnclosure : public SwerveEnclosure {
public:

    GenericEnclosure(   std::string name,
                frc::SpeedController& m_moveMotor,
                frc::SpeedController& m_turnMotor,
                rev::CANEncoder& m_encoder,
                double m_gearRatio);
    ~GenericEnclosure();

};

RobotDriveSwerve.h文件

class RobotDriveSwerve
{
public:
    RobotDriveSwerve(SwerveEnclosure* frontLeftWheel,
                     SwerveEnclosure* frontRightWheel,
                     SwerveEnclosure* rearLeftWheel,
                     SwerveEnclosure* rearRightWheel,
                     double width, double length);
    virtual ~RobotDriveSwerve() = default;

.cpp文件

  //All Drive Motors
  rev::CANSparkMax m_leftFrontDriveMotor{1, rev::CANSparkMax::MotorType::kBrushless};
  rev::CANSparkMax m_leftBackDriveMotor{2, rev::CANSparkMax::MotorType::kBrushless};
  rev::CANSparkMax m_rightFrontDriveMotor{3, rev::CANSparkMax::MotorType::kBrushless};
  rev::CANSparkMax m_rightBackDriveMotor{4, rev::CANSparkMax::MotorType::kBrushless};

  //All Turn Motors
  rev::CANSparkMax m_leftFrontTurnMotor{5, rev::CANSparkMax::MotorType::kBrushless};
  rev::CANSparkMax m_leftBackTurnMotor{6, rev::CANSparkMax::MotorType::kBrushless};
  rev::CANSparkMax m_rightFrontTurnMotor{7, rev::CANSparkMax::MotorType::kBrushless};
  rev::CANSparkMax m_rightBackTurnMotor{8, rev::CANSparkMax::MotorType::kBrushless};

  //All Drive Encoders
  rev::CANEncoder m_leftFrontDriveEncoder = m_leftFrontDriveMotor.GetEncoder();
  rev::CANEncoder m_leftBackDriveEncoder = m_leftBackDriveMotor.GetEncoder();
  rev::CANEncoder m_rightFrontDriveEncoder = m_rightFrontDriveMotor.GetEncoder();
  rev::CANEncoder m_rightBackDriveEncoder = m_rightBackDriveMotor.GetEncoder();

  //All Turn Encoders
  rev::CANEncoder m_leftFrontTurnEncoder = m_leftFrontTurnMotor.GetEncoder();
  rev::CANEncoder m_leftBackTurnEncoder = m_leftBackTurnMotor.GetEncoder();
  rev::CANEncoder m_rightFrontTurnEncoder = m_rightFrontTurnMotor.GetEncoder();
  rev::CANEncoder m_rightBackTurnEncoder = m_rightBackTurnMotor.GetEncoder();

 const double GEAR_RATIO = (1988/1.2);
const double L = 24.5;
const double W = 20.5;

//Enclosure initialization
        GenericEnclosure swerveEnclosure1{"enc 1", m_rightFrontDriveMotor, m_rightFrontDriveMotor, m_rightFrontTurnEncoder,GEAR_RATIO};
        GenericEnclosure swerveEnclosure2{"enc 2", m_leftFrontDriveMotor, m_leftFrontTurnMotor, m_leftFrontTurnEncoder, GEAR_RATIO};
        GenericEnclosure swerveEnclosure3{"enc 3", m_leftBackDriveMotor, m_leftBackTurnMotor, m_leftBackTurnEncoder, GEAR_RATIO};
        GenericEnclosure swerveEnclosure4{"enc 4", m_rightBackDriveMotor, m_rightBackTurnMotor, m_rightBackTurnEncoder, GEAR_RATIO};

//Swerve Drive initialization
        RobotDriveSwerve swerveDrive{swerveEnclosure1, swerveEnclosure2, swerveEnclosure3, swerveEnclosure4, W, L};

错误来自此行RobotDriveSwerve swerveDrive{swerveEnclosure1, swerveEnclosure2, swerveEnclosure3, swerveEnclosure4, W, L};，并引发此错误no instance of constructor "RobotDriveSwerve::RobotDriveSwerve" matches the argument list -- argument types are: (GenericEnclosure, GenericEnclosure, GenericEnclosure, GenericEnclosure, const double, const double)。一切都编译良好，但这是唯一的难题。对不起所有代码，但它是可正确构建的大型类。非常感谢所有能够提供帮助的人！

Answer 1

chown -R tomcat:tomcat /home/ubuntu构造函数正在寻找指针。您需要使用“地址”运算符。更改

RobotDriveSwerve

RobotDriveSwerve swerveDrive{swerveEnclosure1, swerveEnclosure2, swerveEnclosure3, swerveEnclosure4, W, L};

Answer 2

在RobotDriveSwerve的构造函数中，当您在编译器产生错误的行提供引用时，您会期望指向类GenericEnclosure的指针。

没有构造函数“ RobotDriveSwerve :: RobotDriveSwerve”的实例与参数列表匹配-参数类型为
