Unable to select GDB in Qt Creator on Windows

Question

I chose GDB instead of CDB as a debugger in Qt Creator on Windows:

But when I start debugging the program, it fails with this error:

  Unable to create a debugger engine of the type "No engine" 

It works if I select CDB from Combo. Why am I getting this error and how to fix it? I assume I have GDB if it is included in the combo box, right?

Edit: I see where there might be a problem, but still don't know how to fix it:

[Open the above image in a new tab to see full resolution.] It says “Not Recognized” for GDB.

Edit 2: I just remembered that I was using the MSVC compiler, and the Qt libraries were compiled for MSVC:

Perhaps the reason? Although GDB should be able to debug any executable file, not just the files generated by gcc, so I'm not sure if this is relevant.

Answer 1

You cannot use GDB with compiled MSVC code. You seem to be mixing two.

CDB comes with Visual C ++. GDB comes with MinGW (-w64).
