标题:我使用的是mini2440学习板，如何将qt4的范例spreadsheet移植上去？

内容:
买了mini2440学习板，按照用户手册学习了附录1“嵌入式图形系统Qtopia-2.2.0 快速移植”
也成功能在mini2440上添加hello world应用程序并运行！！
最近也买了本C++ GUI QT4学习，第三章有个spreadsheet范例程式，理解完后想像hello world那样添加到mini2440系统上，发现不是那么简单：
论坛看了没有找到相关的方法，可能自己笨找不到，哎~~
就想先在x86上编译，也编译不了：
# make

那位大侠能帮忙解释下啊！！谢谢了

我直接新建一个目录chap03存放spreadsheet程序
使用的liunx系统为Fedora9
x86和arm交叉编译器应该都可以，因为hello word可以编译成功！
