gcc main.c -lGL -lGLU -lglut

neeme

hi:
I have a file (main.c) .
I use gcc main.c -lGL -lGLU -lglut (is ok).
How can i build in qtcreate 4.2.0(qt 5.7.1) ? Thank you!

#include <GL/glut.h>

void myinit();
void display();

int main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
glutInitWindowSize(500,500);
glutInitWindowPosition(0,0);
glutCreateWindow("simple OpenGL example");
glutDisplayFunc(display);
myinit();
glutMainLoop();
}

void myinit()
{
glClearColor(0.0,0.0,0.0,1.0);
glColor3f(0.0,1.0,0.0);

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(0.0, 50.0, 0.0, 50.0);
glMatrixMode(GL_MODELVIEW);

}

void display()
{
GLfloat vertices[3][2] = {{0.0,0.0},{25.0,50.0},{50.0,0.0}};
int j,k;
int rand();
GLfloat p[2] = {7.5, 5.0};
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_POINTS);
for(k=0;k<900000;k++)
{
j=rand()%3;
p[0] = (p[0]+vertices[j][0]) / 2.0;
p[1] = (p[1]+vertices[j][1]) / 2.0;
glVertex2fv(p);
}

glEnd();
glFlush();

}

Hi,

Do you mean having a .pro file with:

SOURCES += main.c
LIBS += -lGL -lGLU -lglut

in it ?
