TQ2440 x86下的QT编译-----first

平台：TQ2440

X86   QT

按照pdf进行编译，有错误，主要是如下的错误：

解决：原来错误在于Makefile，里面重复编译了同样的文件：

         如：moc_first.o: moc_first.cpp \

                                                 first.h

         竟然编译了两次，重复写了两次。

 

[root@iFico hello]#progen -o first.pro（获取*.pro文件）

然后编辑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。

下面是结果啊：
