arm-linux-ldd 怎么生成啊？

arm-linux-ldd 怎么生成或者下载啊？

在arm的linux平台下， 程序运行时，提示：error while loading shared libraries: cannot open shared object file: cannot load shared object file: No such file or directory。  

据说arm-linux-ldd能查出是缺少什么运行时的库。。？

Before you porting arm-ldd to arm system , i was confused how you port your application to arm , you can't know what library was needed?
