mingw32-make[1]: Leaving directory `C:/Qt/4.4.0/hello'
mingw32-make: *** [release] Error 2

这到底是什么错误呢，望高手指点！谢谢！

先通过 qt command prompt 进入cmd
执行
qmake -project
再执行
qmake
最后执行
mingw32-make
即可生产程序。

楼上正确，也可以用nmake编译，但是首先要用qmake预处理

看不懂。。。学习还不到家。。。诶。。。

[gemfield]

目录下只有*.cpp是不能用make的，make命令要是要Makefile文件的，而makefile文件的产生又需要*.pro文件。
所以一般是qmake -project产生.pro;
qmake *.pro产生makefile;

你这是建的QT工程吗？
感觉好像是VC的工程

我是在C:\Qt\4.4.0目录下面建立一个hello文件夹，里面新建了一个hello.cpp执行文件，执行make命令是，产生了这些错误，

#include <QApplication>
 #include <QLabel>
 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);
     QLabel *label = new QLabel("Hello Qt!");
     label->show();
     return app.exec();
 }
