LIBRARY_PATH是编译时候用的,LD_LIBRARY_PATH是程序运行是使用的

LD_LIBRARY_PATH与LIBRARY_PATH的区别

看起来很像，但是完全是两码事。

LIBRARY_PATH is used by gcc before compilation to search for directories containing libraries that need to be linked to your program.

LIBRARY_PATH是编译时候用的

LD_LIBRARY_PATH is used by your program to search for directories containing the libraries after it has been successfully compiled and linked.

LD_LIBRARY_PATH是程序运行是使用的
