我尝试过构建 2.4 的所有版本，当“链接 CXX 可执行文件../../bin/opencv_test_core”时，它们都失败：

我的 CMakeLists.txt 文件是默认文件，但我将其更改为使用 TBB、禁用了文档并打开了详细模式。
执行 ldd /usr/local/lib/libavcodec.so.54 我得到：

任何人都知道可能是什么原因造成的，或者我可以采取什么措施来解决它？我已经为此工作了很长一段时间并且不知所措。任何帮助将非常感激。
我遇到了类似的问题，但如果您升级了 ffmpeg 的一个或多个依赖项，那么这是 ffmpeg 的问题。 FFmpeg 需要重新编译或更新其所有依赖项
