我
安装的是 qt-win-opensource-4.3.4-mingw.exe（安装在c:\qt\4.3.4）
和
devcpp-4.9.9.2_setup.exe（安装在f:\dev-cpp）
在系统变量中加了
PATH:
F:\Dev-Cpp\bin;C:\Qt\4.3.4\bin;
QTDIR:
C:\Qt\4.3.4
QMAKESPEC:
win32-g++
在dev-c++里的工具——》编译选项中
增加了（默认的都保留了）
A、设置inlcude头文件c:\qt\4.2.2\include
B、设置lib库文件c:\qt\4.2.2\lib
在"工程"－"工程属性"里设置：
C、设置连接器库文件，将c:\qt\4.2.2\lib加入其中。
可是按
http://www.qtcn.org/bbs/simple/index.php?t7708.html这个后面说的测试不能通过
错如 如下：
编译器: Default compiler

执行结束
请教各位是为什么！？？
