[Pyobjc-dev] PyObjC code injection on Leopard

[Luc H. <lu...@ho...>]

Greetings,

Is code injection still supposed to work on Leopard ? I can't get any  
of the samples to work. I have especially tried InjectInterpreter and  
no matter what I do, nothing seems to happen. No error message, no  
interpreter window popping up in the target process, nothing.

The injecting process will, at the least, need to be in a particular  
group/user (that I can't remember right now).   Try injecting as root  
and see if it works (as root can do all).

Trying to inject as root causes a segfault, so at least something is  
happening... :)
