Mac OS X系统上类似 ldd 的工具

ldd是用来查看一个可执行文件中包括对哪些共享库的调用，但是在MAC OX X下似乎没有ldd，取而代之的是另一个叫otool的命令，使用该命令的-L命令可以实现ldd的功能。

ldd on Mac OS X

"ldd" in various flavors of Unix is used to check which dynamic libraries are used by the executable. There is no "ldd" command in Mac OS X (Convenient, huh?). Instead, Apple provides something that is talled "otool", which has many different options. One of them is "-L", which displays the linked libraries:

sparrow (13:18)$ otool -L h3dpost.x 

h3dpost.x:
