编译并运行:gcc-lglut-olightlight.c./light至此第一个Linux下的OpenGL程序便诞生了.Enjoyit！

linux下opengl编程在linux下opengl编程,首先需要安装glut包.1安装glut(1)下载地址:fidelio.cacs.louisiana.edu/resources/linux/glut.zip

(2)将glut.zip解压:unzipglut.zip解压后,里面有一个rpm安装包,一个测试文件,一个glut.h,一个makefile,这几个文件都非常重要.(3)安装:pm-iglut-3.7-8.i386.rpm(note:Ifyoualreadyhavealaterglut,userpm-i--forceglut-3.7-8.i386.rpm)(4)把"glut.h"移到"/usr/include/GL":mvglut.h/usr/include/GL(5)cd/usr/lib(6)cplibglut.so.3.7libglut.so(7)回到glut.zip的目录,运行make,然后./cube会看到测试图形

#include<,GL/glut.h>,voiddisplay(void){/*clearallpixels*/glClear(GL_COLOR_BUFFER_BIT),/*drawwhitepolygon(rectangle)withcornersat*(0.25,0.25,0.0)and(0.75,0.75,0.0)*/glBegin(GL_POLYGON),glColor3f(0.0,1.0,1.0),glVertex3f(0.25,0.25,0.0),glColor3f(0.0,0.0,1.0),glVertex3f(0.75,0.25,0.0),glColor3f(1.0,0.0,0.0),glVertex3f(0.75,0.75,0.0),glColor3f(0.0,1.0,0.0),glVertex3f(0.25,0.75,0.0),glEnd(),/*don'twait！*startprocessingbufferedOpenGLroutines*/glFlush(),}voidinit(void){/*selectclearingcolor*/glClearColor(0.5,0.5,0.0,0.0),/*initializeviewingvalues*/glMatrixMode(GL_PROJECTION),glLoadIdentity(),glOrtho(0.0,1.0,0.0,1.0,-1.0,1.0),}/**Declareinitialwindowsize,position,anddisplaymode*(singlebufferandRGBA).Openwindowwith"hello"*initstitlebar.Callinitializationroutines.*Registercallbackfunctiontodisplaygraphics.*Entermainloopandprocessevents.*/intmain(intargc,char**argv){glutInit(&,argc,argv),glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB),glutInitWindowSize(250,250),glutInitWindowPosition(100,100),glutCreateWindow("hello"),init(),glutDisplayFunc(display),glutMainLoop(),return0,/*ANSICrequiresmaintoreturnint.*/}//////////gcc-lglutgl.c-otest先装个freeglut或者mesa.以freeglut举例,装好后会在/usr/include/GL中出现glut.h,在/usr/lib下出现libglut.so,如果没有就自己拷一下.

linux下编写OpenGL程序的一些准备工作需要用到的软件包有两个,glut和tmake,分别可以从以下两个网址下载:opengl./resources/libraries/glut/glut-3.7.tar.gzftp://ftp.trolltech./freebies/tmake/tmake-1.8.tar.gz

下载后的文件假设都放在/usr/src中

首先是安装glut库,以下是从linux.找到的编译glut库的手册.
