How do you debug using 'Code::Blocks 20.03' (the "mingw" version)? - debugging

Question

I have built a Console Application using Code::Blocks 20.03, which was installed using codeblocks-20.03mingw-setup.exe. The defaults for the installation directory(see Note01) and the installation type (Full), were used.
I tried to Debug by using the Debug menu, clicking Start/Continue, and debugging failed.
I guess the important information from the log of what happened is
Starting the debuggee failed: No executable specified, use `target exec'
The full output from trying to debug is given below.
My question is, how do you debug using Code::Blocks 20.03 (the "mingw" version)?
Full Output from trying to run a debugging session follows.

===============================
In building my project I used the defaults from the Select Compiler dialog box.
Note01:
It looks as if you should (date 11th April 2021) always use the default directory, to install. I installed a version of Code::Blocks in C:\Program Files\CodeBlocksSmall when I went to uninstall it, the uninstaller would only accept C:\Program Files\CodeBlocks as the directory to uninstall from. I deleted the CodeBlocksSmall directory manually. I noticed this behaviour when I installed using codeblocks-20.03-setup.exe.

=======================
It looks as if a prior installation of MinGW was inadvertently being used by the attempted debugging session(this is no longer possible). See the involvement of the file
C:\MinGW\bin\gdb.exe, in the line
Starting debugger: C:\MinGW\bin\gdb.exe -nx -fullname -quiet -args
Now when I try to run a debugging session, failure occurs differently (see just after the next four lines).
It looks to me as if I need to at least to change the behaviour indicated by
Starting debugger: C:\MinGW\bin\gdb.exe -nx -fullname -quiet -args
to behaviour produced by
Starting debugger: C:\Program Files\CodeBlocks\MinGW\bin\gdb.exe -nx -fullname -quiet -args

There, the error message is like the one shown just above, and see also below
Starting debugger: C:\MinGW\bin\gdb.exe -nx -fullname -quiet -args C:/Codeblocks20.03/ConsoleApp/program01INcForAnswer/bin/Debug/program01INcForAnswer.exe failed
Note that, in both cases, Code::Blocks is trying to invoke a debugger from the directory C:\MinGW\bin

Answer 1

To get debugging working, the type of fix described here wil be required if you install the MinGW version of Code::Blocks 20.03 on Windows, using codeblocks-20.03mingw-setup.exe ( the 8th April 2021 version, with the default installation accepted ).
What I did to get it to work was the following.
From the Settings menu I clicked on Debugger.., then on the left of the screen selected Default, a debugger type. This showed me Executable paths which was set to
C:\MinGW\bin\gdb.exe
I changed this to
C:\Program Files\Codeblocks\MinGW\bin\gdb.exe
I was then able to use the debugger.
