That is clearly a bug in the "Check Project" code. It'd be great
if you could file a bug report.
Now there is another Error:
Parameters are not compatible with this function:
return callGL(gl_ctx, windowptr)
What is the definition of "windowptr"?
I don't know. Someone else wrote this code for me. I am trying to
contact the person.
Since I don't understand this code I am hoping some experts will
give me some guidance.
The most frustrating thing is that everything worked perfectly in
RB 5.5

"windowptr" looks like an error in the original code... I didn't
write it, but whoever did probably abandoned or otherwise forgot
to update the Classic target so the error wasn't caught until you
changed the target constants and tried to compile it on Mac OS X.
That bit of code was never meant to run on Mac OS X, and if it
does, it _will_ crash
I just got this reply from the guy who wrote the code. He in turn
got help from many other sources:
Not sure where it is defined. I read where Joe said in OS X that
Self.MacWindowPtr is getting the right port, vs the different one
used in OS 9. (where just a GetPort would work)
And that they were defined as same?
Perhaps this thread might be of aid. I really don't understand what
they would have changed in the newer version of RB that would break
something like this?

A snip is below.
Did they issue a compatibility/changes list? (might help to know if
that is the case)
The language ref for WindowPtr just says "When passing a window to
a declare, use a WindowPtr, not a Window object."
WindowPtr is a datatype for declarations. You pass a Window object
in a WindowPtr parameter. It grabs the Window.Handle -- the
MacWindowPtr property is deprecated -- and passes that to the
external function. It's really a convenience datatype; you could
declare such parameters as Integer and pass Window.Handle instead.
