Mac OS X Glut build instructions(在Mac上用glut库编写OpenGL程序)

1. Building GLUT apps under Mac OS X
There are only a few modifications you need to make to the
  robot.c sample to get it compiled on your Mac.  These
  instructions were tested under OS X 10.3 (Panther) with XCode 1.1.
XCode comes with everything you need to build GL apps, including
  stable versions of OpenGL, GLUT, gcc and all the related make tools.

XCode by default places the include files for GLUT in a different
  location than MESA, so to build robot.c you need to change line
  46 from
#include <GL/glut.h>
to
#include <GLUT/glut.h>
After making this change you are ready to build from the command
  line:
gcc -framework GLUT -framework OpenGL -framework Cocoa
  robot.c -o robot
Note the use of the -framework option to make use
  of OS X's packaged libraries.  The Cocoa framework provides the OS
  services required by GLUT, such as interfacing with the window
  manager (Aqua).
I will post a sample makefile here which can be used to compile your files under OS X or Linux as necessary without modification; as soon as my Sutherland account is activated.

void angleUpdate( int delay )
{
    float twopi = 2 * M_PI;
    myTime = ( myTime > twopi ) ? 0 : myTime + .03;
    myAngle = sinf( twopi * myTime );
    glutTimerFunc( delay, angleUpdate, delay );
    glutPostRedisplay();
}
int main( int argc,
          char * argv[] )
{
    glutInit( &argc, argv );
    // choose a visual and create a window
    glutInitDisplayString(  "stencil>=2 rgb~8 double depth>=16 samples" );
//    glutInitDisplayMode( GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH );
    glutInitWindowSize( 450, 300 );
    glutCreateWindow( "GLUT Configuration Example" );
    // initalize our opengl (context is now valid)
    prepareOpenGL();
    // register callback functions
    int delay = 50;
    glutTimerFunc( delay, angleUpdate, delay );
    glutDisplayFunc( draw );
    glutMainLoop();
}
//codefragmentend,app

void altinit()
{
//codefragmentbegin,stringinit
    glutInitDisplayString(  "stencil>=2 rgb~8 double depth>=16 samples" );
//codefragmentend,stringinit

　　　　Build commands:


　　


g++ -framework GLUT -framework OpenGL  main.cpp -o test　　
　　Run:
　　./test

　　　　



　　　　




　　　　


　　　　Notice:

　　(1) Framework 类型提供的lib和其他.a & .dylib的库文件不同；



　　(2) 编译时使用 -framework GLUT的编译选项。
