how do you build DTrace on Mac OS X?

I'm trying to build the dtrace target in the Xcode project using the advice here:

http://osx86.b开发者_如何学Coeaja.info/2009/10/building-xnu-kernel-on-snow-leopard/

But I get: libproc.m:24:49: error: CoreSymbolication/CoreSymbolication.h: No such file or directory

I realize CoreSymbolication is a private framework, but Apple must make this header available somewhere in order for me to build dtrace, right? Can someone point me to the necessary files to build dtrace?

As you probably figured out, Apple only has to release parts of the kernel which are taken from other open-source projects, and that doesn't include the userland libraries that they build on top of the kernel. CoreSymbolication/CoreSymbolication.h sounds a lot like a userspace header for Obj-C though, so you can probably build the kernel DTrace utilities without it. (Although I could very well be wrong.)

I would guess it's being used for symbol identification in the userland dtrace(1m) command. If only there was a tool that could help us figure this out... :-D

# dtrace -n 'pid$target:CoreSymbolication::entry {}' -c 'dtrace -ln syscall::write:entry'

It looks like the library is in use by the dtrace command, anyway.
