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.

?Source code:

#include?<iostream>

#include?<math.h>

void?prepareOpenGL()
{
????myAngle?=?0;
????myTime?=?0;
}

void?draw()
{
????glClearColor(?0,?.5,?.8,?1?);
????glClear(?GL_COLOR_BUFFER_BIT?|?GL_DEPTH_BUFFER_BIT?);

????glMatrixMode(?GL_MODELVIEW?);
????glLoadIdentity();

????//?choose?a?visual?and?create?a?window

//????glutInitDisplayMode(?GLUT_RGB?|?GLUT_DOUBLE?|?GLUT_DEPTH?);
????glutInitWindowSize(?450,?300?);
????glutCreateWindow(?"GLUT?Configuration?Example"?);

????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 類型提供的lib和其他.a & .dylib的庫文件不同；

(2) 編譯時使用 -framework GLUT的編譯選項。
