opengl的编程问题
高手看看这个opengl的程序为什么在visual studio下drawoneline编译不成功呢?#include <glut.h>
#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>
#define drawOneLine (x1,y1,x2,y2) glBegin(GL_LINES);glVertex2f((x1),(y1));glVertex2f((x2),(y2));glEnd();
void init (void)
{
glClearColor(0.0,0.0,0.0,0.0);
glShadeModel(GL_FLAT);
}
void display (void )
{
int i;
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0,1.0,1.0);
glEnable(GL_LINE_STIPPLE);
glLineStipple(1,0x0101);
drawOneLine(50.0,125.0,150.0,125.0);

}

}

}
int main(int argc,char **argv)

glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB);
glutInitWindowSize(400,150);
glutInitWindowPosition(100,100);
glutCreateWindow(argv[0]);
init();
glutDisplayFunc(display);
glutReshapeFunc(reshape);
glutMainLoop();
return 0;
