• GLIBCXX_3.4.14 not found

• 增加查找动态库的路径

Keep the previous path, don't overwrite it:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/

You can add it to your ~/.bashrc:

echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/your/custom/path/' >> ~/.bashrc

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"$PWD"

Alternatively you can execute program with specified library dir:

/lib/ld-linux.so.2 --library-path PATH EXECUTABLE

https://stackoverflow.com/questions/13428910/how-to-set-the-environmental-variable-ld-library-path-in-linux

• ldd列出程序依赖的动态库

Example:

$ ldd /bin/ls

readelf -d /bin/ls | grep 'NEEDED'
