被/usr/local/lib搜索的共享库？我有这个错误:

[Leo@chessman ~]$ whereis ffmpeg
ffmpeg: /usr/local/bin/ffmpeg
[Leo@chessman ~]$ ffmpeg
ffmpeg: error while loading shared libraries: libavcore.so.0: cannot open shared object file: No such file or directory

这个页面 - http://labs.qt.nokia.com/2011/10/28/rpath-and-runpath/ - 说明了ld.so中的库搜索顺序:

Unless loading object has RUNPATH:
    RPATH of the loading object,
        then the RPATH of its loader (unless it has a RUNPATH), ...,
        until the end of the chain, which is either the executable
        or an object loaded by dlopen
    Unless executable has RUNPATH:
        RPATH of the executable
LD_LIBRARY_PATH
RUNPATH of the loading object
ld.so.cache
default dirs

然后建议:

当您发送二进制文件时,要么使用RPATH而不是RUNPATH,要么确保在运行之前设置LD_LIBRARY_PATH.

因此,使用RPATHwith RUNPATH是不好的,因为RUNPATH取消了类似的RPATH间接动态加载不能按预期工作？但为什么然后RPATH被弃用RUNPATH呢？

有人可以解释一下情况吗？
