没有规则可以创建目标 /usr/lib/libX11.so

Question

我正在使用 SFML 库编写一个程序，它需要 libX11。我最近刚刚从旧版本升级到 ubuntu 11.04，从那以后我就无法编译我的程序。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.

我想也许当我升级 Ubuntu 时，该软件包由于某种原因被卸载，但根据 Synaptic，我有 libX11-dev （我只是假设这就是我应该寻找的，但我可能是错的）。

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.

并使用 --reinstall 标志运行给出以下输出：

事实证明，对所有内容进行简单的 make clean 就足够了。我仍然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，一切都会编译并正常工作。
