QBENCHMARK resulting in undefined reference problems

[Momergil]

Hello!

I'm trying to build a benchmark application for some tests with Qt. I was going to use QElapsedTimer when I found this article (http://qt-project.org/doc/qt-4.8/qte...tutorial5.html) telling about the usage of QBENCHMARK macro for doing such a work. I tried to implement it in my code after including QtTest (using Qt 4.8) and Qt Creator returned me lots of undefined reference errors.

//in .cpp
#include <QtTest/QtTest>
 
using namespace QTest;
 
//...
 
void MainWindow::on_startQBenchmark_clicked()
{
    QBENCHMARK {
        int aaa = 0;
    }
}

//in .cpp
#include <QtTest/QtTest>

using namespace QTest;

//...

void MainWindow::on_startQBenchmark_clicked()
{
    QBENCHMARK {
        int aaa = 0;
    }
}

I can't understand why is that happening

Thanks,

Edit: I noticed now that the compiler errors appears even if I don't call QBENCHMARK.

Have you added

QT += testlib

QT += testlib

To copy to clipboard, switch view to plain text mode 

to your .pro file?

Cheers,

QT += testlib

That did the trick


Thanks,

Edit: or not... only half of it :T Now it compiles fine, but I receive a segmentation fault (pointing to the macro) each time I try to run it, even using the exact same code of the page linked above. =/
