QtCreator's Debugger not working with CLI apps

[Pete Carter]

I created a simple C++ CLI app (Non-Qt Project > Plain C++ Application) in QtCreator.

main.cpp

#include <iostream>

int main()
{
    std::cout << "Hello, world!\n\n";
    return 0;
}

hello_world.pro

TEMPLATE = app
CONFIG += console c++17
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += \
        main.cpp

Now when running this app, the output is as expected:

That "qtc-process_stub" error is mentioned here and i think it has nothing to do with this topic.

Notice that i am using the external terminal, the app is running in the external terminal. Everything works fine.

---

Now when i try debugging the app, no output is shown in the terminal from the debugger:

Terminal window:

IDE's window:

Even when i try setting breakpoints, the debugger is showing no output ?!

The debuggers are configured correctly in the settings, both GDB and LLDB.

It's also worth mentioning that the debugger works fine in Qt projects.

@Pete-Carter Would you mind opening a bugreport on bugreports.qt.io and describe your build environment a little more? What compilers, debugger, qt version, Qt Creator version etc.

Thanks!

I believe Qt Creator reroutes the output when debugging. Doesn't seem to make much sense when running a CLI application. At least on Windows there needs to be special treatment for GUI applications because they don't have a console output by default.

The output might show in the Global Debugger Log (menu View -> Views -> Global Debugger Log). However, it will be intermingled with a lot of other things. (I am not sure if it is the Global Debugger Log view or another view. But there is a special view somewhere.)

Issue fixed in QtCreator 11.0.3

Downloaded it from here: https://download.qt.io/snapshots/qtcreator/11.0/11.0.3/43/
