This makes no sense...

So I have this code...

Code:

---

#include <QtGui/QApplication>
#include "mainlogin.h"
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    mainlogin w;
    w.show();
    return app.exec();
}

---

I get the compiler error:

Code:

---

main.cpp:10: error: expected '}' at end of input

---

So this code works...

Code:

---

#include <QtGui/QApplication>
#include "mainlogin.h"
 
int main(int argc, char **argv)
{
    QApplication app(argc, argv);
    mainlogin w;
    w.show();
    return app.exec();
}}

---

Then I get this error:

Code:

---

moc_mainlogin.cpp:68: error: expected '}' at end of input

---

After I fix that, I get

Code:

---

c:\ndk_buildrepos\qt-desktop\src\winmain\qtmain_win.cpp:131: error: undefined reference to `qMain(int, char**)'

---

Is anyone else having this problem?

Isn't it quite obvious, that you have something wrong in included file?

Code:

---

#include "mainlogin.h"

---

Look for missing ";" or "}"

probably a missing ";" at the end of the class definition.

Checked the header... Do you guys see anything off?

    Q_OBJECT
public:

        setAttribute(Qt::WA_DeleteOnClose); // make sure memory is cleaned up
 
        // Temporary
        QVBoxLayout *layout = new QVBoxLayout;
        layout->addWidget( new QLabel("Label 1", this) );
        layout->addWidget( new QLabel("Label 2", this) );
        setLayout(layout);
    }
};
 
#endif // MAINWIN_H

I see your using QT_END_NAMESPACE without a QT_BEGIN_NAMESPACE, so if the former resolves to null, then you'll be missing a '}' in that file.

Nevermind. It was just a bug, reinstalled Qt and rewrote most of the code. Everything is working on my side. Now its just all of the 300 errors of the Qt headers. Well, I do one error..

Quote:

---

mainlogin.cpp:3: error: definition of implicitly-declared 'mainlogin::mainlogin(const mainlogin&)'

---

But I'm sure I know the fix for that. And I just cleared all of the Qt Errors. Rouge macros was to blame.

Ehm, what bug? The only bugs I can see are in your code... E.g. mainlogin.h line 10 misses a } for closing the namespace.

I see that now... The odd thing is that Qt Actually generated most of the code... So that's worrying.. Anyways, I fixed it. And now for my debugging problem...

What do you guys think? Fail on my part or fail on the compilers fault?

Qt generates correct code. It's only when you try to "improve" that mistakes start to occur. Especially the code that has this nice warning about not modifying a file because it is autogenerated.

No really........... I'm not trying to improve that code, I just get Qt to generate some of the code, then I do the rest. I never touch anything else.

You still modified a file which is auto generated and not meant to be modified. I very much doubt UIC would have autogenerated the "login" method. It doesn't even belong in this class.

So you probably accidentally altered the file in such a way which caused the errors.

In C++ you usually "improve" code by subclassing.

Nevermind... Just wondering about my debugging problem. I never hit this problem before.
