Qt / Qt Creator - 程序意外完成。 <程序路径>坠毁 [英] Qt/Qt Creator - The program has unexpectedly finished. <program's path> crashed

问题描述

我对C ++和Qt 5.2.1有些新。我实际上学习如何使用Qt。为了做到尽可能简单，我使用的是Qt Creator 3.0.1。

I'm somewhat new to C++ and to Qt 5.2.1. I'm actually learning how to use Qt. To do it as easy as possible, I'm using Qt Creator 3.0.1.

我在main.cpp文件中写了一小段代码项目：

I've written this little piece of code in the main.cpp file of my project :

#include <QApplication>
#include <QPushButton>

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

    QPushButton bouton("Hello !");
    bouton.show();

    return app.exec();

}

并且.pro文件p>

And the .pro file (by default) :

SOURCES += \
    main.cpp

我试图让它运行，然后我得到了问题QApplication：没有这样的文件或目录。

I tried to make it run, then I got the issue "QApplication : no such file or directory".

然后，我在.pro文件（完整文件）中添加了QT + = widgets：

Then, I added "QT += widgets" to the .pro file (full file) :

SOURCES += \
    main.cpp
QT += widgets

现在我得到： p>

And now I get :

Starting <path to .exe>... 
The program has unexpectedly finished.
<path to .exe> crashed

请告诉我如何使它工作。
感谢您的阅读和帮助。

Please, tell me how to make it work. Thanks for reading and for your help.

推荐答案

我已经看过网络，寻求如何安装Qt5。没有足够的教程，它是非常令人费解的，使其在Windows上正常工作。

I've look all over the web, seeking how to install Qt5. There's not enough tutorials on it and it's very puzzling to make it work properly on Windows.

我终于安装了Qt4，这是更稳定，更容易使其工作。

I have finally installed Qt4, which is more stable and easier to make it work.
