大家好，我在ubuntu下安装OpenGL提示下面错误：
sudo apt-get install mesa-common-dev
Reading package lists... Done

看提示好像是依赖libx-11，但是去apt-get install libx11-dev又会出现类似错误，刚开始xuexi，不太明白，多谢大神指教

我看到的东西，开放图形库（英语：Open Graphics Library，缩写为OpenGL）是个定义了一个跨编程语言、跨平台的应用程序接口（API）的规范，它用于生成二维、三维图像。这个接口由近三百五十个不同的函数调用组成，用来从简单的图形比特绘制复杂的三维景象。而另一种程序接口系统是仅用于Microsoft Windows上的Direct3D。OpenGL常用于CAD、虚拟实境、科学可视化程序和电子游戏开发。
很复杂我不懂！

恩，是一个开放三维图形库，在Linux下有个叫mesa的库实现的，不过还是谢谢您

安装aptitude也会出现依赖错误，不知道这一类如何解决，请大神帮忙看看哦
