Installing GLUT for MinGW [转]

1 Introduction:
OpenGL is independent of any windowing system. As a result, it contains
no functions for opening windows or interacting with the user.
Each windowing systems that supports OpenGL has its own library
that procides the support.
GLUT, the OpenGL Utility Toolkit, is a simple windowing system that
has been ported to several different operating systems. It is commonly
used when teaching OpenGL.
This document describes the installation of GLUT for
developing on MS-Windows using MinGW. It assumes that you have already
installed MinGW.
2 Getting Started:
The first thing you need to do is download the binaries for the Win32
port of GLUT.
GLUT 3.7.6
3 Putting Files in the Right Place:
You need to copy three files from the .ZIP file.
Copy glut.h to the MinGW\include\GL directory.
Copy glut32.lib to your build directory (i.e., the directory
that you compile into and link from).
Copy glut32.dll to the same directory where your executable
will be created.
(You can actually put glut32.dll in any directory in
your path.)
4 Building an Executable:
You need to be aware of the following:
You must #include <windows.h> before
you #include <"GL/glut.h">
When you link, you must link-in glut32.lib (and not
use the -lglut32).
You may get some warnings like the following:
ignoring #pragma comment
warning: 'int glutCreateMenu_ATEXIT_HACK(void (*)(int))' defined but not used
You can ignore them.
Help resolving other problems is available at the MinGWiki.
5 Testing Your Installation: You can use the following small program (named test.c) to test your installation:
1 #include <windows.h>
2 #include "GL/glut.h"

10 glBegin(GL_POLYGON);
11 glVertex2f(-0.5, -0.5);
12 glVertex2f(-0.5, 0.5);
13 glVertex2f(0.5, 0.5);
14 glVertex2f(0.5, -0.5);
15 glEnd();
16
17 glFlush();
18 }

20 void init()
21 {
22 glClearColor(0.000, 0.110, 0.392, 0.0); // JMU Gold
23
24 glColor3f(0.314, 0.314, 0.000); // JMU Purple
25
26 glMatrixMode(GL_PROJECTION);
27 glLoadIdentity();
28 gluOrtho2D(-1.0, 1.0, -1.0, 1.0);
29 }
30
31 int main(int argc, char** argv)
32 {
33 glutInit(&argc, argv);
34 glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
35 glutInitWindowSize(640, 480);
36 glutInitWindowPosition(0, 0);
37 glutCreateWindow("Test");
38 glutDisplayFunc(display);
39 init();
40 glutMainLoop();
41 }
You should be able to build this program from the command line as follows:
g++ -o test -Wall test.c -mwindows glut32.lib -lopengl32 -lglu32
6 Using jGrasp:
Some of you may have used MinGW under jGrasp in the past.
You can do so with GLUT but you will have to change some settings
in jGrasp.
In jGrasp, choose Settings on the main menu,
pull down to Compiler Settings, and then
pull down to either Workspace or
Project.
Next, click on the Compiler tab and change the "Language"
to C.
From here, you can set the "FLAGS or ARGS" for "Make", the "Compiler",
etc... See, for example, the flags and arguments used in the
example above.
