链接libavcodec和libavformat：未定义的引用
我正在尝试编译我正在使用ffmpeg库的项目。 该项目用C语言编写。头文件适当地包含在源代码中。 特别是，它似乎使用libavcodec和libavformat ，并且这些库在Makefile中与LDFLAGS正确链接。 以下是使用的标志：
-lavcodec -lavformat -lswscale -lavutil
现在，因为Ubuntu附带的打包库太过时了，我下载了ffmpeg的最新源代码，编译并安装它。 我删除了通过包管理器安装的所有打包库。 现在，尽管添加了上面的标志，我得到了很多未定义的引用，我似乎无法解决它。 以下是关于未定义引用的输出：

任何人都可以解释这里出了什么问题，以及我如何解决这个问题？
你错过了一些图书馆。
