Re: About to give up on Lua....!

[Ando Sonenblick <ando@...>]

Chris,

Nice to know there are some other Mac + Lua people out there!

Of course, true to form: as soon as you get super frustrated at post an
"About to give up on Lua!" message, you clear your head and are able to dig
deeper and discover the problem:

All the c std routintes (fopen, fputs, etc) were not defined since I really
never use those routines...

So once I realized that much, it was just a matter of rooting through and
replacing/removing those calls (or the entire routine they are in).  At this
point "dofile" isn't important to our product, etc...

What gets my goat is that although the computer may be over 50 years old and
has come a vastly long way, error reporting still SUCKS!  OK, so the code is
calling fputs which isn't defined: so you report that GetToolTrapAddress
isn't defined!?!?!

Argh....

Anyway, I'm a much happier camper now that I can move forward.

Thanks for your help,
Ando
