1、下载freeglut
https://www.transmissionzero.co.uk/software/freeglut-devel/
这里选择了mingw版本
2、解压得到：bin,include,lib三个文件夹
include/GL中的是头文件，放在devc++的include/GL下面
bin里面的是dll文件，放在C:\Windows\System32 下面
lib里面是.a文件，放在devc++的lib下面
3、新建一个空项目

工程-》工程选项-》参数 添加三个文件 libglu32.a 、 libglut32.a 、libopengl32.a
这三个文件都在DEV-C++的安装目录中的lib文件夹中。

5、写入测试代码

#define GLUT_DISABLE_ATEXIT_HACK
#include <windows.h>
#include <GL/glut.h>
 
const int   A = 500;  /* length of a side of the monitor window */
const float B = 500;  /* length of a side of the clipping rectangle */
const float C = 200;  /* length of a side of the square the program draws */
 
void myinit(void)
{
  glClearColor(0.7, 0.7, 0.7, 0.0); /* gray background */
 
  glMatrixMode(GL_PROJECTION);      /* In World coordinates: */
  glLoadIdentity();                 /* position the "clipping rectangle" */
  gluOrtho2D( -B/2, B/2, -B/2, B/2);/* at -B/2, its right edge at +B/2, its bottom */
  glMatrixMode(GL_MODELVIEW);       /* edge at -B/2 and its top edge at +B/2 */
}
 
void display( void )
{
                                    
  glClear(GL_COLOR_BUFFER_BIT);     /* clear the window */
 
  glMatrixMode(GL_MODELVIEW);       /* The following coordinates are expressed */
  glLoadIdentity();                 /* in terms of World coordinates */
 
  glBegin(GL_POLYGON) ;             /* draw a filled polygon */
      glColor3f ( 1.0, 0.3, 0.2);       /* draw in light red */
      glVertex2f( -C/2, -C/2 );         /* (x,y) */
      glVertex2f(  C/2, -C/2 );         /* (x,y) */
      glVertex2f(  C/2,  C/2 );         /* (x,y) */
      glVertex2f( -C/2,  C/2 );         /* (x,y) */
  glEnd();
 
  glFlush();                        /* send all commands */
}
 
int main(int argc, char** argv)
{
  glutInit(&argc,argv);
  glutInitWindowSize( A, A );       /* A x A pixel screen window  */
 
  glutInitDisplayMode( GLUT_RGB | GLUT_SINGLE);
  glutCreateWindow("My Rectangle"); /* window title                   */
  glutDisplayFunc(display);         /* tell OpenGL main loop what     */
  myinit();                         /* set attributes                 */
 
  glutMainLoop();                   /* pass control to the main loop  */
  return 0;
}

6、编译运行
