Mac OS X: What is the best way to estimate code size and static data in a program?

I want to get an estimate of how much code and static data is used by my C ++ program?

Is there a way to find out by looking at executable or object files? Or something I can do at runtime?

Will otool help?

  • "size" is a traditional tool and works in all unix styles.
  • "otool" has a slightly finer grain control and has many options.

.

$ size python
__TEXT  __DATA  __OBJC  others  dec     hex
860160  159744  0       2453504 3473408 350000
