当我做

$ gcc cube.c -lglut -lGL -lGLU -lSDL 
/usr/bin/ld: cannot find -lSDL
collect2: error: ld returned 1 exit status

当我做

$ sudo apt-get install libsdl*

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libsdformat-dev : Depends: libboost-regex-dev but it is not going to be installed

似乎 libsdl 安装不成功。在搜索 libsdl 时，有两个版本 libsdl1 和 libsdl2。我正在考虑寻找其他安装它们的方法。有人对安装有什么建议吗？

@steeldriver：我做了你的建议，输出如下：

$ sudo apt-get update && sudo apt-get upgrade

根据道格的建议解决

Open up Software & Updates > Updates tab & make sure that 
the first 2 are enabled. (- trusty-security, trusty-updates). 
If one or the other wasn't enabled then do so, 
after that reload sources & proceed.

感谢您的解决方案，道格！感谢所有参与这个问题的人，尤其是 steeldriver 和 AB！
