@JKSH Hover your mouse cursor over the red symbol (!). What does the tooltip say?
It says "Could not determine debugger type".

[jsulm]

@dahu74fr Can you post the screenshot of what is shown if you select the debugger? I mean in the lower part of the window.

[dahu74fr]

@hskoglund I don't think so because i work under Windows 10 64 Bits.

[hskoglund]

Ok. Another guess: do you have any antivirus installed (I mean apart from the normal Windows 10 one)?

Edit: also. can you check the version of that gdb? If you open a CMD window and type:

C:\Programmation\qt\tools\mingw810_64\bin\gdb.exe

(and type quit to quit the debugger)

My antivirus is the windows 10.
Nothing. As you can see :

[jsulm]

@dahu74fr So, it does not work even from command line.
I suggest to reinstall MinGW, most probably gdb is corrupted.

[dahu74fr]

@jsulm GDB.exe is the one include in the installation package of Qt.
If i have to reinstall it, where can i find it ?
Best regards.

Use the maintenance tool to uninstall and then install again MinGW.

[dahu74fr]

@jsulm It have been already done with no success.
I also tried to uninstall and reinstall Qt with no success.
I also tried to install the 32 bits version with the same problem.

To get more info, try downloading DebugView https://docs.microsoft.com/en-us/sysinternals/downloads/debugview
Start it , open a CMD window and then try the same gdb.exe command as above

[dahu74fr]

@hskoglund OK. I downloaded it. I launch it. But where i open a CMD window ?

[hskoglund]

Hi start DebugView and let it run by itself. Then open a CMD window the same way you did before, and try to start gdb.exe again.

[dahu74fr]

@hskoglund OK. But nothing. Isn't it for 32 bits debugview ?

[hskoglund]

Hmm you're running as an Administrator, try logout and login as a normal user.

[dahu74fr]

@hskoglund I launched CMD as Administrator.
Now i launched it as User.
I am the only User on my computeur with Administrator rights.
I must launch Debugview as Administrator.
If not i have an error.
Now, it's the same result :

[hskoglund]

Ok, also check that the compiler works, in the same CMD window, type:

C:\Programmation\qt\tools\mingw810_64\bin\g++ -v

Edit: I forgot to ask, what error did you get when you tried to run DebugView as a User, not as an Administrator?

[dahu74fr]

@hskoglund Yes. It works.
For information, i downloaded Mingw 8.10 64 bits. I install it and compare the two directories. The one in Qt and the one i installed. Every thing is the same.

An other step i tried : i have CodeBlocks installed on my computer. I try to launch the gdb32.exe in the directory of codeblocks and it works. (Third screenshot).

Error launching DebugView :

[hskoglund]

I see, it might be the MinGW versions in CodeBlocks and Qt are fighting each other.
So try launch another CMD window, this time click on the start button and type mingw then select this CMD:

Note that it's called 7.3.9 but that's a typo, when you click on it it should show:

In this CMD window type

gdb

@hskoglund Here is what i have :

and the result :
