Can't select GDB in Qt Creator on Windows

Question

I've selected GDB instead of CDB as the debugger in Qt Creator on Windows:

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

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

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

Edit: I see where the problem might lie, but still no idea how do I fix it:

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

Edit 2: I just remembered that I'm using the MSVC compiler, and the Qt libs are compiled for MSVC:

Maybe that's the reason? Although GDB should be able to debug any executable, not just ones generated by gcc, so I'm not sure if it's relevant.

Answer 1

You can't use GDB with MSVC-compiled code. It seems you're mixing the two.

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