没有规则将目标设为/usr/lib/libX11.so

如何解决没有规则将目标设为/usr/lib/libX11.so

|| 我正在使用SFML库编写一个程序，该程序需要libX11。我最近刚从较旧的版本升级到ubuntu 11.04，从那时起，我一直无法编译程序。我收到以下错误：

make[3]: *** No rule to make target `/usr/lib/libX11.so\',needed by `lib/libsfml-window.so.2.0.0\'.  Stop.

我想也许是当我升级Ubuntu时出于某种原因而卸载了该软件包，但是根据Synaptic的说法，我有libX11-dev（我只是假设这是我应该寻找的，但是我可能错误）。 编辑： 运行

apt-get install libx11-dev

给出以下输出：

sudo apt-get install libx11-dev
Reading package lists... Done

libx11-dev is already the newest version.
  g++-4.4 libstdc++6-4.4-dev
Use \'apt-get autoremove\' to remove them.
0 upgraded,0 newly installed,0 to remove and 32 not upgraded.

并使用--reinstall标志运行可以得到以下效果：

解决方法

        事实证明，我所需要的只是简单的4英镑。我仍不清楚更新之间发生了什么，但是当我从头开始重建项目时，所有内容都能编译并正常工作。
