1) Obviously, how do I fix my error, and

很明显，我该如何改正我的错误。

2a) I suspect that I need to install a Qt library/package or something or other but I just can't seem to figure out what I need to do. How do I determine what it is that I am actually missing, and

我怀疑我需要安装一个Qt库/包或者其他的东西，但是我似乎不知道我需要做什么。我如何确定我实际上错过了什么?

我可以在哪里安装?(如何最好地使用apt文件，定位，或者其他什么?)

I'm using ubuntu 12.04, 64bit and g++4.6.3

我使用的是ubuntu 12.04, 64位和g++4.6.3。

vertstatsForm.h:12:14: fatal error: Qt: No such file or directory

I looked inside vertstatsForm.h:12:14 and the 12 line is #include < Qt >

我看了看vertstatsForm内部。h:12:14和12行是#include < Qt >。

#ifndef VERTSTATSFORM_H
#define VERTSTATSFORM_H

#include <Qt>  <-----line 12
#include <qvariant.h>
#include <qdialog.h>
#include <Qt3Support/Q3GridLayout>
#include <QLabel>
