Linux debugging has failed error

[s002wjh]

using Qtcreator 5.7 on Centos 6.8 with freshly installed GDB 7.11/python 2.7.12, when running .pro (generate from qt5.5) I get "debugging has failed" message when try to run in debug mode but fine when just running. any idea?

is there anyway to check under Qtcreator which GDB/python is using? I have multiple version of GDB/python installed

Hi,
Where do you find that message - Issues, Debugger console, General messages?
There's only one python helper as far as I know, but the debuggers you can check in Tools > Options > Build & Run in the Debuggers tab.

I found it under application output console, there aren't any additional message in other console.
its
debugging starts
debugging failed
debugging finished.

anyway to know which GDB/python QT is using in the QT in the QT build&run/debugger it detect 2 GDB, one is the older version and one is new. is it possible QT is using the old one or maybe the new GDB didn't compile with newer python?

Just check if the debugger that's selected in the Kit exists - check if the path to the executable is valid and you can call it from the command line.
