- how to generate the interpreter sources using ConfigurationOfCogVM
- build the VM
- run and debug it with gdb and XCode

Re: [ANN] PharoCasts with Experts: Debug the Cog VM with Mariano Martinez Peck

Hi guys. I think there is a mistake..."expert"??? No....I am FAR from being an expert. I am just a newbie like you but that I try to share the minimum I learn.
BTW, the video has a couple of mistakes I did that I want to share just in case:

1) I downloaded git in an ugly directory (inside the build of another git repository) and then I don't know why there was an error and I couldn't download git sources again. So, I needed to stay with the ugly and confusing directory.

2) When I debugged with XCode you could see there were a lot of '??' in the debugger. This was wrong and it was because of a compiler flag in the Mac builds. This was fixed a couple of days ago, what we were still using an old version

3) when we put a flag in the method lookup for the #dnu it didn't work because (I think) of the black magic that happens when executing things from the workspace. If I would have evaluated the same code but from a method, it should have worked

BTW, How can I have such an ugly voice? heheh

Cheers

Mariano

You are not alone. Most people usually don't like how they sound.
But you are not TV narrator/reporter to care about that. :)

You did a great job Mariano & Laurent. Thanks!
