vs2005+QT4商业版编译问题 [复制链接]

我是一个新手，在用vs2005+QT4商业版第一次编程时碰到一下问题：
程序：
#include <Qt/qapplication.h>
#include <QtGui/QLabel.h>
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QLabel *label = new QLabel("Hello Qt!");
    label->show();
    return app.exec();
}
环境变量设置为：include:C:\Qt2005\4.4.3\include
                               lib:C:\Qt2005\4.4.3\lib

错误如下，怎么解决？

估计是没有经过pro直接用vs写个main函数就编。。就算这样也应该在工程属性设置一下要链接的库啊。。。

我实在vs里面建立了一个空白工程啊，然后直接建立一个.cpp文件。

请高手讲解具体操作过程！在线等待

怎么没有人回复呢

已经解决

請問可以敘述一下是如何解決的嗎?
我現在的狀況和你完全相同...

呵呵，是因为没有moc，信号和插槽机制，必须定义Q_OBJECT宏，标准c++没有对Qt的元对象系统所需要的动态元信息提供支持，qt提供了moc工具解决这个问题。
建议大家把解决的问题的方法分享一下。
GENERATE MOC FILES FOR HEADERS USING QT EVENTS (Q_OBJECT):
Perform this step for all header files that inherit from a QT class - i.e. any class with Q_OBJECT.  The following example uses a ficticious header file called MyHeaderFile.h You must fully qualify where the header file is or the moc utility will not find it.

In the Solution Explorer, right Click on MyHeaderFile.h and select Properties -> Custom Build Step -> General  
Set Command Line to $(QTDIR)\bin\moc MyHeaderFile.h -o tmp\moc\moc_MyHeaderFile.cpp
Set Description to Moc'ing MyHeaderFile.h ...
Set Outputs to tmp\moc\moc_MyHeaderFile.cpp
Set Additional Dependences $(QTDIR)\bin\moc.exe;
Replace MyHeaderFile with the actual name of the header file to be Moc'd.

7) ADD THE MOC FILES TO YOUR PROJECT:
First, build your project by selecting Build -> Build Solution or (F7) to generate moc files (you'll get a bunch of linking errors - don't worry).

From the Solution Explorer, right click on the  Project_Name and select Add -> New Folder
Name the new folder "Generated Moc Files" (or whatever you want).

Again, from the Solution Explorer right click on the "Generated Moc Files" folder and select Add -> Add Existing Item

Lastly, locate the moc file from the directory specified in step 6 (i.e. tmp\moc\moc_MyHeaderFile.cpp) to add it to your project.

That's it, you should be up and running.  Good Luck.
