QCoreApplication console application does not output with Valgrind

[Guerrian]

I have a QCoreApplication console application which works fine if I run it normally, but when I run it with "Analyze -> Valgrind Memory Analyzer", there is no output after "hi":

Runner::Runner(QCoreApplication *parent)
{
    app = parent;
}

void Runner::run()
{
    cout << "hi" << endl;
    QCommandLineParser parser;
    parser.setApplicationDescription("Description...");
    parser.addHelpOption();
    cout << "does not output here" << endl;
    app->quit();
}

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);
    Runner *runner = new Runner(&app);
    QTimer::singleShot(0, runner, SLOT(run()));
    return app.exec();
}

@Guerrian QCommandLineParser should be place in main()!

int main(int argc, char *argv[])
{
    QCoreApplication app(argc, argv);

    QCommandLineParser parser;
    parser.setApplicationDescription("Description...");
    parser.addHelpOption();

    parser.process(app);

    Runner *runner = new Runner(&app);
    QTimer::singleShot(0, runner, SLOT(run()));
    return app.exec();
}

@KroMignon Still doesn't work with Valgrind... no output.

Both testcases work fine for me on the command line, with or without valgrind.

@Christian-Ehrlicher I tried running on the command line and I got the message:

error while loading shared libraries: libMyLib.so.0: cannot open shared object file: No such file or directory

So then I created a bash script just called "myscript":

#!bin/bash
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/daniel/Documents/MYLIB/lib
export LD_LIBRARY_PATH
exec "./MyApp"

And made it executable:

chmod +x myscript

But when I run it says:

bash: ./myscript: bin/bash: bad interpreter: No such file or directory

[Christian Ehrlicher]

I'm pretty sure you don't have bin/bash in your current work dir...

[Guerrian]

@Christian-Ehrlicher I forgot the slash, it should be:

#!/bin/bash

@Guerrian said in QCoreApplication console application does not output with Valgrind:

I forgot the slash

correct :)
