求助！hello QT

按照QT程序开发完全手册写了个hello的程序，结果出这么一个错误，请高人指点一二：
编译器的输出信息如下

一样的问题，运行qpe，也说没找到

重复定义了！
看我的博客 http://blog.csdn.net/sunhy1021/archive/2009/12/08/4965305.aspx
里面有写

编辑hello.pro文件，修改为：

TEMPLATE                 =app

CONFIG                    =qtopia warn_on release        （把qt改为qtopia，这样就可以调用qtopia的库）

HEADERS                  =hello.h

SOURCES                  =hello.cpp \

                                    main.cpp

INTERFACES             =                        

一定要将“INTERFACES  = hello.ui”修改为“INTERFACES  =   ”否则会出现错误：报错，重定义。

1、在我们手册里面讲了Makefile的修改的，你应该没有注意到这个问题；
2、qpe不能运行，如果qpe没有编译成功，需要重新编译qtopia，然后在设置环境变量后执行qpe，如果qpe已经编译成功了，在设置环境变量后执行qpe。

如何看qpe是否编译成功了？
