qt4编译已通过
然而，编写的简单程序链接的时候却出了很多错误
好像library,directories都没有错啊
程序如下
#include
#include
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QLabel *label = new QLabel("Hello Qt!");
label->show();
return app.exec();
}
错误如下：

应该是要链接的库没有加上的原因吧。

已加上
呵呵
确实忘记了
但是只要添加了q_object那个宏又不行了

把你的源代码和工程文件内容都帖出来吧

谢谢版主关心
搞定了
哈哈
把 nmake生成的 moc_*.cpp
加入工程中就可以在vc2005中 编译调试了
