I have a PPC application that was previously built with CW 5 that I
imported into CW 9. After much effort and some help from this group,
it now builds under CW 9 (albeit with some warnings that probably need
attention)

The problem I'm having is when I run, the app fails during startup
with the following error dialog:

The application "(null)" could not be launched because of a shared
library error:
":<build target name><build target name><InterfaceLib> <>"

I tried changing project settings by removing InterfaceLib from the
Libraries-CFM file group and adding it to the Libraries-PPC group.
This resulted in the same runtime error but for a different library,
so I repeated the steps for that library. After several iterations
for different libraries I wound up back at the first error with
InterfaceLib again.

Any suggestions on how to resolve this would be appreciated.
Greg

InterfaceLib-based apps will only run on MacOS 9 - is that where you're
testing this? If not, then you've got to switch over to CarbonLib, and
that's beyond the scope of a quick reply. :-)

Thanks for your response :)

I was running it in the CW9 debugger on OS X. Since it is a PPC app I
guess I can't expect anything to work that way (sorry, seems silly to
have tried it now..) When I run it under OS 9 I get a fatal error on
startup stating "The application has unexpectedly quit because an
error of type 12 occurred."

It's not a Carbon app and doesn't need to be, I only need it to run
under OS 9 natively, but I have to build it using CW 9 on OS X.
Sounds like what I *should* be doing is taking my OS 9 debug build and
running under the debugger on OS 9. Should this work? Running an OS 9
app built using CW 9 under the CW 5 debugger?

I haven't debugged an InterfaceLib-based app in a long time, and
definitely not with CodeWarrior 9. However, that sounds like what you
should be doing. As I understand it, there's some special build of the
IDE that allows you to debug CodeWarrior 9 apps on OS 9, tucked away in
one of the Extras folders or CDs? Maybe Ron will chime in here with more
info.

Do you have Macsbug installed? If not, and you call Debugger() or
DebugStr() you'll get err 12 IIRC.

With CW 8 at least, you must run the IDE in Classic (or OS 9) to debug
Classic apps.

I doubt it.
