What does this mean?

Using Arduino Programming Questions

I am trying to program a steppermotor, and this is my programming:

#include <StepperMotor.h>

StepperMotor motor(8,9,10,11);

void setup(){
Serial.begin(9600);
motor.setStepDuration(1);
}

void loop(){
motor.step(1000);
delay(2000);
motor.step(-1000);
delay(2000);
}

And this is the error message:

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

How do I fix this?

Just guessing have you defined StepperMotor motor?

I see no int in your code just as the error message said

3

StepperMotor(int pin1, int pin2, int pin3, int pin4, int stepsPerRevolution);

Step 1: Do what the message says.

It looks like you have somehow deleted Stepper.cpp from the directory where Stepper.h lives.
