Hi Mariano,

It's probably a versioning problem as I am on 10.6.3 (like [1]).

I'll send you in a private mail the generated VM sources so you can try to compile yourself if you like.

Cheers, Adrian

Now there's also a DTrace provider for the Squeak VM:

DTrace is a powerful, kernel-based dynamic tracing framework. With the new provider one can analyze the execution of Pharo/Squeak applications.

My post is an introduction that should get you quickly started. I've attached a pre-compiled VM for OS X.

Hope you like it :)

Hi John,

DTrace on my unix VM thinks it does not know ioShowDisplayOnWindow (I guess because I use X11 display). With a Mac VM I it works. To trace ioShowDisplayOnWindow you don't need a dedicated probe (and hence no specialized VM). The DTrace "pid" provider allows you to trace any function entry (and return):

pid$target::ioShowDisplayOnWindow:entry { printf("%s'%s\n", probemod, probefunc); }

Cheers, Adrian

Ah, nice, yes very nice.

One interesting one to have a probe for would be ioShowDisplayOnWindow so one can understand how much screen drawing goes on.
