[self-interest] Re: Self-Stamtisch? + Self on Mac

[David Ungar]

Vince,

Thanks for your support.
I am making minimal changes and it is working.
But even minimal has meant redoing a bunch of graphics calls.
Also, Self wants to catch exceptions so if there is a bug in the VM, 
you get a chance to save a snapshot.
And, when using the SIC (not a factor on the Mac), it uses illegal 
instructions and address traps.
The problem is that the old call (something like 
InstallExceptionHandler) is not supported in Carbon.
Instead, you have to use MPSetExceptionHandler.
But that will not work on the main thread (I don't know why), only on 
subsidiary threads.
Which is fine under OS X, but under 9, you cannot make toolbox calls 
from subsidiary threads.
I tried just using that one pre-carbon routine for the 9 version, but 
then I got this
"Cannot launch application, could not find library: <<CarbonLib>>" message.
Anyone out there know about this stuff?

For now, it is just running without catching exceptions.

- Dave
