Thread: Glut two errors upon being compiled: "not declared terms"

Okay, I have two errors which I cannot figure out (they should be easy, I am knew to C++). They are:

C:\Users\drewtoby\Desktop\tby\main.cpp|88|error: 'display' was not declared in this scope|

AND

C:\Users\drewtoby\Desktop\tby\main.cpp|91|error: 'Reshape' was not declared in this scope|

for this code:

Code:

#include <GL/glut.h>
#include <iostream>
#include <math.h>
#include <stdlib.h>
using namespace std;

float xpos = 0, ypos = 0, zpos = 0, xrot = 2, yrot = 2, angle=2.0;

void enable (void) {
    glEnable (GL_DEPTH_TEST); //enable the depth testing
    glEnable (GL_LIGHTING); //enable the lighting
    glEnable (GL_LIGHT0); //enable LIGHT0, our Diffuse Light
    glShadeModel (GL_SMOOTH); //set the shader to smooth shader
    }


void renderScene(void) {
   glClear(GL_COLOR_BUFFER_BIT);
   glBegin(GL_TRIANGLES);
   glColor3f(1,0,0);//Change the object color to red
      glVertex3f(-2.0,-0.1,0.0);
      glVertex3f(0.4,0.0,0.0);
      glVertex3f(0.0,0.0,0.0);
   glEnd();
   glFlush();
}


void keyboard (unsigned char key, int x, int y) {

    if (key=='q')
    {
    xrot += 1;
    if (xrot >360) xrot -= 360;
    }

    if (key=='z')
    {
    xrot -= 1;
    if (xrot < -360) xrot += 360;
    }

    if (key=='w')
    {
    float xrotrad, yrotrad;
    yrotrad = (yrot / 180 * 3.141592654f);
    xrotrad = (xrot / 180 * 3.141592654f);
    xpos += float(sin(yrotrad)) ;
    zpos -= float(cos(yrotrad)) ;
    ypos -= float(sin(xrotrad)) ;
    }

    if (key=='s')
    {
    float xrotrad, yrotrad;
    yrotrad = (yrot / 180 * 3.141592654f);
    xrotrad = (xrot / 180 * 3.141592654f);
    xpos -= float(sin(yrotrad));
    zpos += float(cos(yrotrad)) ;
    ypos += float(sin(xrotrad));
    }

    if (key=='d')
    {
    yrot += 1;
    if (yrot >360) yrot -= 360;
    }

    if (key=='a')
    {
    yrot -= 1;
    if (yrot < -360)yrot += 360;
    }
    if (key==27)
    {
    exit(0);
    }
}


int main(int argc, char **argv) {
   glutInit(&argc, argv);
   glutInitDisplayMode(GLUT_DEPTH | GLUT_SINGLE | GLUT_RGBA);
   glutInitWindowPosition(100,100);
   glutInitWindowSize(800,800);
   glutCreateWindow("MynDrawn: An Open Source Alternative to Minecraft");
   glutDisplayFunc(renderScene);
glutIdleFunc (display); //update any variables in display,
//display can be changed to anyhing, as long as you move the
//variables to be updated, in this case, angle++;
glutReshapeFunc (Reshape); //reshape the window accordingly
glutKeyboardFunc (keyboard); //check the keyboard
glutMainLoop (); //call the main loop
return 0;
}

Do I need to include another Glut file, or is it something else? Thanks!

You need something called "display".

Okay, thanks!!!! I'll find/build/mod those files!!!
