为什么Qte2.2 编译的时候显示缺少头文件

为什么Qte2.2 编译的时候显示缺少头文件，make 天嵌给的first。显示为：
arm-linux-g++ -c -pipe -DQWS -fno-exceptions -fno-rtti -Wall -W -O2 -DNO_DEBUG -I/usr/lib/qt-3.1/include -I/include -o main.o main.cpp
main.cpp:3:35: error: qtopia/qpeapplication.h: No such file or directory
In file included from /usr/lib/qt-3.1/include/qvariant.h:42,
                 from first.h:12,
                 from main.cpp:1:
/usr/lib/qt-3.1/include/qstring.h: In member function 'ushort& QChar::unicode()':

main.cpp: At global scope:

有没有运行设置环境变量的脚本，在QT的安装目录中
