LD_LIBRARY_PATH 设置正确了吗？
#2 [bluesge 04-09 22:04]
export LD_LIBRARY_PATH=$QTDIR/lib:$QPEDIR/lib
对吗?
谢谢了!

我猜测的 你的pro里面有了
INTERFACES = hello.ui
但是你的
HEADERS 里面又有了 hello.h
或者你的
SOURCES 里面有了 hello.cpp
因为hello.ui生成的文件就是hello.h和 hello.cpp 你又把它放到HEADERS 和 SOURCES里面 就导致了多重定义了
其实 INTERFACES = hello.ui里面就包含了对生成的hello.h和 hello.cpp 处理了 就不要往HEADERS 和 SOURCES加hello.ui生成的东西了,也不要另外创建hello.h和 hello.cpp这样的文件,因为会被生成的覆盖了.......
