问题描述
是否 / usr / local / lib 搜索共享库？我有这个错误：
Is /usr/local/lib searched for shared libraries ? I have this error:
[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 [Leo@chessman ~]$ ls /usr/local/lib/libav* /usr/local/lib/libavcodec.a /usr/local/lib/libavfilter.a /usr/local/lib/libavcodec.so /usr/local/lib/libavfilter.so /usr/local/lib/libavcodec.so.52 /usr/local/lib/libavfilter.so.1 /usr/local/lib/libavcodec.so.52.108.0 /usr/local/lib/libavfilter.so.1.74.0 /usr/local/lib/libavcore.a /usr/local/lib/libavformat.a /usr/local/lib/libavcore.so /usr/local/lib/libavformat.so /usr/local/lib/libavcore.so.0 /usr/local/lib/libavformat.so.52 /usr/local/lib/libavcore.so.0.16.1 /usr/local/lib/libavformat.so.52.94.0 /usr/local/lib/libavdevice.a /usr/local/lib/libavutil.a /usr/local/lib/libavdevice.so /usr/local/lib/libavutil.so /usr/local/lib/libavdevice.so.52 /usr/local/lib/libavutil.so.50 /usr/local/lib/libavdevice.so.52.2.3 /usr/local/lib/libavutil.so.50.36.0 [Leo@chessman ~]$
推荐答案
确保您的 LD_LIBRARY_PATH 设置为包括您要搜索的所有目录，然后再次测试。
Make sure your LD_LIBRARY_PATH is set up to include all directories you want to search and then test it again.
您可以通过以下方式快速测试：
You can test this quickly with:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib ffmpeg
which will set it only for that invocation.
或者，您可以编辑 /etc/ld.so.conf 其中包含搜索的默认目录。某些Linux发行版可能不包含该文件中的 / usr / local / lib 。
Alternatively, you can edit /etc/ld.so.conf which contains the default directories searched. Some Linux distributions may not include /usr/local/lib in that file.
请注意，您可能还需要通过运行$ $来更新缓存 /etc/ld.so.cache c $ c> ldconfig （作为root用户，或使用 sudo ）。
Note that you may also need to update the cache /etc/ld.so.cache by running ldconfig (as root, or with sudo).
