入门讨论帖--编译qt文件出的错误，大家一起看看。

  用qt designer  生成了  .ui文件
然后运用.ui文件，# uic -o *.h *.ui  
                                # uic -o *.cpp -impl *.h *.ui  
生成了. cpp  和  .h文件
编辑了mian.cpp  然后用友善hello里面的./build  编译

这个是整个包

提示下列错误

对了还有一个  .pro文件是我把hello  里的文件考过来然后把 对应的文件修改得到的

g++  -o /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/image/opt/Qtopia/bin/first .obj/release-shared/first.o .obj/release-shared/main.o .obj/release-shared/first.o .obj/release-shared/moc_first.o .obj/release-shared/moc_first.o   -lqtopia2 -lqtopia -lqpe -L/opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/lib -L/opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qt2/lib -lqte

从编译的输出看，最后链接时first.o和moc_first.o都链接了两遍，当然会出现重复的symbol定义。

恩
我查看的生成的Makefile，的确是有重复的项目，我把重复的变异选项给删除掉后，编译仍旧有错。正在分析原因。
顺便问下  有同志按照这个帖子的两种方法 测试成功的么？
            帖子如下：http://www.aiothome.net/read.php?tid-2998.html

这个是我可以编译成功的例子，不知对你有用不！

谢谢您的例子，您是按照上面那个帖子做的么？
  

我看过TQ的，做成功过，包括ARM-qtopia的，用上面链接的方法也可以

我看了
调用ui库和不用ui库是两种方法。
我用tq的方法也实现了，谢谢你的例子。
但是那篇帖子的第一种方法我还是没有做成功。
准备在看看具体文件分析下原因。

我在Fedora 9中同样碰到了你这样的问题··没有测试成功 ··不知道如何解决啊··

建议你看下http://www.aiothome.net/read.php?tid-4399.html  这个帖子
然后好好的看你的cpp  h  pro  文件
问题就在这个4个文件里面了
我的那个问题在main。cpp文件里面
我是把两种方法和在一起使用，结果显而易见会有缺少文件的情况。
希望有什么问题大家再交流。
