So, when you run it in a debugger, where in your code does it show the error is occurring?

[Eastborn]

i tried doing qDebug() << "startup" at the start of the main.cpp but it wasnt shown in the console when i debug it it just quits when i start it up.

[koahnig]

Is your main.cpp compiled without error/warning as you have posted above?

[Eastborn]

yes it is compile error-free and not even warnings, i did have one when i wanted to implement skype but that was because fopen() was unsafe, but i dont have this code in anymore and it is completely error/warning free

[koahnig]

Well, in starting your thread you have posted:
[quote author="Eastborn" date="1329839165"]
main.cpp
@#include <QtGui/QApplication>
#include "mainwebwindow.h"
#include "qskclasses.h"

MainWebWindow* mainForm = 0;
QSKSignalDispatcher* dispatcher = 0;

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

mainForm        = new MainWebWindow();
dispatcher      = new QSKSignalDispatcher(mainForm);
dispatcher->ConnectToUI();

mainForm->show();

#ifdef WIN32
    QString runtimePath = "..//..//..//Skypekit//bin//windows-x86-skypekit.exe";
#endif

#ifdef __APPLE__
    QString runtimePath = "..//..//..//Skypekit//bin//windows-x86-skypekit.exe";
#endif

#ifdef __linux__
    QString runtimePath = "..//..//..//Skypekit//bin//windows-x86-skypekit.exe";
#endif

QProcess runtime;
if (!runtime.startDetached(runtimePath))
{
    qDebug() <<"ERROR: Unable to execute " + runtimePath;
}
else
{
    return a.exec(&#41;;
}

}

Not all return pathes are providing a return value. So, I would expect at least a warning, when it is not an error.

So, the information posted may be inconsistent.
From your post I understand that you are not even been able to see the output. You may want to check also that your main is the main you are thinking it is.

Anyhow, I would suggest to eliminate functionality by commenting out. You have to vary until you find the source of problem.

i got it fixed, it were dlls that were missing in the debug folder...

sorry to bother anyone here
and thanks for your support

[koahnig]

You are welcome

All people go through such experiences. ;-)

you have to put the necessary third party library dll files beside your exe file.
