ubuntu下搭建openGL环境

时间:2022-08-10 14:43:29

1.      建立基本编译环境

sudo apt-get install build-essential

2.      安装OpenGL Library

sudo apt-get install libgl1-mesa-dev

 3.      安装OpenGL Utilities

sudo apt-get install libglu1-mesa-dev

4.      安装OpenGL Utility ToolKit

sudo apt-get install freeglut3-dev

对于不用IDE的学习者,这些就足够了,在编译时链接相应的库就行。如,对于一个文件simple.c,代码如下

/*
* GLUT Shapes Demo
*
* This program is test harness for the sphere, cone
* and torus shapes in GLUT.
*
* Spinning wireframe and smooth shaded shapes are
* displayed until the ESC or q key is pressed. The
* number of geometry stacks and slices can be adjusted
* using the + and - keys.

编译命令:gcc simple.c -o simple -lGL -lGLU -lglut

然后运行编译后的程序./simple,结果如下:

若采用Code::Blocks,需要添加链接库

打开Setting->Complier...->Linker Settings

ubuntu下搭建openGL环境

将libGL.so,libGLU.so,libglut.so添加进去,建立工程需要建立console应用程序,否则找不到相应的库。
