Hello BB NDK devs,

Anyone know what the state of watchpoint support is?

HW Watchpoints don't seem to work.

SW Watchpoints seem to work once but stall the application thereafter.

Thanks!

I can confirm they work from Qt creator. I have not tried any hardware break or watch points but in general I have had no issues setting soft break and watch points on my playbook for debugging...

Of course I had to configure, build and deploy the Qt libs in debug mode for this to work though

Cheers,

Jon

I'm also using QT Creator, and i dont have QT libraries compiled in debug mode. But i also can debug my apps, of course, i cant debug into QT libs, but i really dont need that.

"i cant debug into QT libs, but i really dont need that. "

I hope you didn't just jinx yourself!

No i did not. I mean i cant go inside source of them (Qt libraries), but can debug my program.

Hi,

Can you show me the steps you perform to toggle a watchpoint?

Hi Martin,

I am enabling the watchpoint from the gdb console in QNX momentics:

set can-use-hw-watchpoints 0   <-- disable hardware watchpoints

watch expression

Also attempted using the UI to do the watch operation. Same results.

Thanks,

Stephane

Hmm this is odd - As far as I know the UI mechanisms in place are functional - I would recomment logging an Issue for this here:
