<solved> For Qt creator, gdb is not triggering

[ajaijames]

Hi Qt developer fellows.

I am a Qt newbie, and struggling to get the debugger setup working for a creator project. I have a Qt creator project done in Windows mingw environment. The problem is that I am unable to debug it using the IDE.
I have python 2.7 and 3.4 installed in my stem with environment variables set as
PYTHONHOME=C:\Python27
PYTHONPATH C:\Python27\Lib

The build is working fine, but the debug status solid bar is turning red, and I can see a fail message in the Application output status window

Debugging starts
Debugging has failed
Debugging has finished

The error message from the log says that
ImportError: No module named itertools
UNEXPECTED GDB STDERR:

The debugger log captured from Windows ->Views ->DebuggerLog is as below
Any help is appreciated

Thanks in advance,
James

Your Python installation seems to be broken (either as-is, or by your explicit use of PYTHONPATH and PYTHONHOME environment variables - neither should be needed)

"itertools" is not a Python module Qt Creator actively uses. It seems to be pulled in in your setup by GDB itself.

Thank you very much andrep, for the kind help. You proved right. I deleted the environment variables, uninstalled python installations and qt installation. The I reinstalled qt environment. Now I am able to trigger gdb.

Thanks a lot again
