Hello,
Please find below the code for my first simple OpenGL program, but it gives me the following error:
g4b1e1@ubuntu:~/programming$ gcc -lGL -lglut cube.c -o cube
/tmp/ccCQkTKm.o:cube.c:function display: error: undefined reference to ‘gluLookAt’
collect2: ld returned 1 exit status
g4b1e1@ubuntu:~/programming$
Program Code:
#include <GL/glut.h>
#include <GL/gl.h>
#include <stdlib.h>void reshape(int, int);
void display(void);
void keyboard(unsigned char, int, int);int main(int argc, char** argv)
{
glutInit(&argc, argv);
glutInitDisplayMode (GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(500,500);
glutInitWindowPosition (100, 100);
glutCreateWindow(argv[0]);
glClearColor(0.0,0.0,0.0,0.0);
glShadeModel(GL_FLAT);
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutKeyboardFunc(keyboard);
glutMainLoop();
return 0;
}void reshape(int w, int h)
{
glViewport(0,0,(GLsizei) w, (GLsizei) h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glFrustum(-1.0,1.0,-1.0,1.0,1.5,20.0);
glMatrixMode(GL_MODELVIEW);
}void display(void)
{
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0,1.0,1.0);glLoadIdentity();
//glMatrixMode(GL_PROJECTION);
gluLookAt(0.0,0.0,5.0,0.0,0.0,0.0,0.0,1.0,0.0);
glScalef(1.0,2.0,1.0);
glutWireCube(1.0);
glFlush();
}void keyboard(unsigned char key, int x, int y)
{
switch(key) {
case 27: exit(10);
break;
}
}
I tried to browse for the solution, but coludn’t get it.
Kindly guide.
