I get the same issue with system or pip pyqt. If I press Ctrl+C, the application exits. If I import platform.machine() and press ctrl+c, the application shows a stack trace where it's waiting for uname to exit.

System Details

Kubuntu 18.04, Qt-Inspector master 0e538d327746bec6e44bb23237543b25ed8ed36f . Qt 5.9.5

I ran make -j4, is that an issue?

Thank-you for including the logs in the bug report. The stacktrace shows that the crash is happening in code related to the Qt Resource System (qrc) which runs early on startup and is unrelated to Qt Inspector. It is possible that Qt Inspector is changing the environment in a way that indirectly leads to this.

What I would suggest doing at this point is creating a minimal "Hello World" Qt application, maybe one that just creates a blank widget and shows it, and see if you can launch Qt Inspector against that. This will tell us if Qt Inspector is not working at all or if there is something in the more complex environment of eg. Konsole or Okular which causes a problem.

If I press Ctrl+C, the application exits. If I import platform.machine() and press ctrl+c, the application shows a stack trace where it's waiting for uname to exit.

What is the stack trace in that case?

I probably can't reply soon, I rebooted to Windows for the first time in months maybe, so I can't test it now.

Hi same behavior on LXDE under ubuntu Ubuntu 16.04.6 LTS Just created empty qt widget app and when tried to attach qtinspector to it it says - Local socket state changed QLocalSocket::ConnectingState Local socket reported error QLocalSocket::ServerNotFoundError Local socket state changed QLocalSocket::UnconnectedState Failed to connect to local socket server in target process 4294 Failed to inject helper library into process Failed to send top-level widget request fetch to child process

please tell me if i need to provide other information thanks!

Did you build the application for Qt 4 or Qt 5? What version of Qt are you using in your test app?

please let me know what else needed thanks

robertknight commented 5 years ago

Did you set the USE_QT5 build option when building Qt Inspector? If not, please try that (see https://github.com/robertknight/Qt-Inspector/issues/19#issuecomment-487158737) and let me know if that works.

deweloprela commented 5 years ago

i'm sorry to bother you with this but how to properly set cmake -DUSE_QT5 ? as when doing this way i get

Parse error in command line argument: -DUSE_QT5 Should be: VAR:type=value CMake Error: No cmake script provided. CMake Error: Problem processing arguments. Aborting.

this cmake -D USE_QT5 . Parse error in command line argument: -D Should be: VAR:type=value CMake Error: No cmake script provided. CMake Error: Problem processing arguments. Aborting.

finally with this cmake -D=USE_QT5 . i actually got executable which name is - USE_QT5qtinspector but it still use qt4 as one line from cmake output says - `This warning is for project developers. Use -Wno-dev to suppress it.

I think the syntax is cmake -DUSE_QT5=ON, but my memory may be fuzzy.

deweloprela commented 5 years ago

ok cmake with -DUSE_QT5=ON actually produced executable but trying to connect still return:

Using cmake version 3.13.2 with flag -DUSE_QT5=1 works just fine on my PyQt5 app. gdb.log.gz

I have the same problem in Ubuntu 20.04 (QT5) and troubleshooting, it seems that in the library lib/libQtInspector.so the function qtInspectorInit() is not called, so the socket is not created by InspectorServer() and in my case the code is hanging at

    QString socketPath = InspectorServer::socketName(*pid);
    while (!QFile::exists(socketPath))
    {
#ifdef Q_OS_UNIX
        usleep(100 * 1000);
#endif
    }

(PreloadInjector.cpp). In particular analyzing a little more I found that QMetaObject::invokeMethod(this, "runInitFunc", Qt::QueuedConnection) is exeuted but StartupHelper::runInitFunct() is not.
