RE: [cdt-dev] Possible to use the qtc-debugging-helper (Either DSF/CDI)
|
Maybe I'm misunderstanding the main issue, probably because I'm mostly Mac-ignorant. Michael's comment was
"I forgot to mention that I am on "that troublesome platform, OS X", where the only GDB that seems to work is the one from Apple which is like version 6.3 or something like that so using the Python Pretty Printers will not work for this particular platform."
I took this to mean you can't use GDB 7.0 (DSF or CDI) on Mac.
+1 on your call for end-user feedback.
Thanks,
Warren
