Hi folks,
As part of a cross-platform effort, I need to incorporate some rather large
C++ libraries into Metacard. The first thing I need to produce is an XCMD for
Macintosh. I've written many in the past in C, but never in C++. What I have
found is that every time I try to throw an exception, POOF! Metacard quickly
disappears. No "unexpected error" message, no system crash, it just quits
abrubtly.
This holds true for an XCMD that looks like this:
void main(XCmdPtr paramPtr) {
try {
throw(1);
} catch(long l) {
}
}
I found the following notes in my Codewarrior help, which seem related, but I
can't see how they come into effect:
If exceptions are enabled, you can throw exceptions across any code that's
compiled by the CodeWarrior C/C++ compiler. You cannot throw exceptions
across the following:
� Mac OS Toolbox function calls
� Libraries compiled with exception support turned off
� Libraries compiled with versions of the CodeWarrior C/C++ compiler
earlier than CodeWarrior 8
� Libraries compiled with CodeWarrior Pascal or other _compilers
If you throw an exception across one of these, the code calls _terminate()
and exits.
I am using CW5, and have compiled with only the following libraries:
InterfaceLib
MSL C.PPC.Lib
MSL RuntimePPC.Lib
Does anyone have an idea what I'm doing wrong? I can't seem to get to the
bottom of this one.
Thanks,
