似乎libsdl安装没有成功。 在搜索libsdl时，有两个版本libsdl1和libsdl2。 我正在考虑找到一些其他方法来安装它们。 有人对安装有任何建议吗？
@steeldriver：我做了你的建议，输出结果如下：

AB根据您的要求。 这是评论中的命令输出。

由道格的建议解决
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.
谢谢你的解决方案，道格！ 感谢所有参与此问题的人特别是钢铁驱动器和AB！
打开“软件和更新”>“更新”选项卡，确保启用前2个。 （ – 可信赖安全，可信赖更新）。 如果未启用其中一个，则在重新加载源并继续之后执行此操作。
如果两者都在那里尝试切换主页上的服务器>从下载：使用主服务器。 然后重新加载资源并查看。
您需要libsdl1.2-dev（1.2.15-8ubuntu1.1）才能使用它应该是，于04/14发布 – http://packages.ubuntu.com/trusty-updates/libsdl1.2-dev
尝试像gcc cube.c $(pkg-config --libs glut gl glu sdl) 。 虽然不完全确定这些包名。
