Please Help me How to install QT on VC++ 2008

So, it's not a include Qt headers error, this means VC recognize your Qt installation. I suspect something wrong in your code. Can you post the code ?

@
#ifndef QT_H
#define QT_H

#include <QtGui/QMainWindow>
#include "ui_qt.h"

class Qt : public QMainWindow
{
Q_OBJECT

public:
Qt(QWidget *parent = 0, Qt::WFlags flags = 0);
~Qt();

private:
Ui::QtClass ui;
};

#endif // QT_H
@

@#include "qt.h"

Qt::Qt(QWidget *parent, Qt::WFlags flags)
: QMainWindow(parent, flags)
{
ui.setupUi(this);
}

Qt::~Qt()
{

}
@

@#include "qt.h"
#include <QtGui/QApplication>

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Qt w;
w.show();
return a.exec();
}

First, please be more patiently. We all do the support here in our spare time and as volunteers. If your topic has that much answers, someone will surely come back with an answer.

As others already have mentioned, do not name your class Qt! This will conflict with the Qt namespace in the Qt libs itself. Additionally, it's good practice to not prefix your own classes with Q or Qt, as this is informally reserved for Qt's own classes.

sorry :( my IDE is visual stduio 2008 pro sp1. can i compile with this ?
i try to set Environment variable and download "qt-everywhere-opensource-src-4.7.4" then configure and run nmake but return error code 02

goetz

Yes, this works.
You can use the prebuilt binaries for VS2008 - there's no need to build them yourself.

[quote author="cincirin" date="1323286429"]Try to rename your files. From what I see you have Qt.cpp and Qt.h in your project. And don't use only Qt in your namespaces or class definitions or other defined type.[/quote]

You have made these changes ? If yes, you still have errors ? If yes, please post new code with the changes.
