GDB "non-stop mode" in Qt Creator

toralf

Is there any way I can use gdb's "non-stop mode" - see https://sourceware.org/gdb/onlinedocs/gdb/Non_002dStop-Mode.html - when debugging in Qt Creator?

I tried adding

set non-stop on

to Additional Startup Commands in Options->Debugger->GDB, but after this, debug sessions seemed to get completely stuck; execution wasn't interrupted at break-points, and the Stop Debugger button was unable to stop the gdb process. The following was displayed in the status view

NOTE: INFERIOR STILL RUNNING IN STATE InferiorRunOk.
>100^error,msg="Target is executing."
dCOOKIE FOR TOKEN 100 ALREADY EATEN (InferiorRunOk). TWO RESPONSES FOR ONE COMMAND?
sExecutable failed: Target is executing.

I'm using Qt Creator 3.2.2.

By try and error, I found out that you should switch to the right "Thread" in the threads drop-down list to be able to use gdb properly.
What I did was to enter the command "set non-stop on" in "Additional Startup Commands" of the debugger configuration and catch the right thread.

That being said I am no expert on this matter, as matter of fact I got to know this "non-stop mode" for five minutes. So don't blame me if it does not respond for you. (for me it did with Qt Creator 3.6.0 and gdb 7.9)
