环境：fedora 9
最新版本的qtopia 2.2.0
编译安装正常，也可以正常运行了。

不过编译hello，之后要运行Hello，提示说找不到命令。

把生成的hello文件放到qtopia/bin文件夹里，再运行run-hello

我确认过了，qtopia/bin文件夹里面也是有hello可执行文件。还是不能运行。
[root@localhost bin]# cd /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/bin
[root@localhost bin]# ls hello
hello
[root@localhost bin]# cd ../../..
[root@localhost x86-qtopia]# cd hello
[root@localhost hello]# ls
build  hello_base.ui  hello.desktop  hello.pro  Makefile
hello  hello.cpp      hello.h        main.cpp   run-hello     //这里的hello就是从那个地方复制过来的。
[root@localhost hello]# ./run-hello
Using display 0
./run-hello: line 17: hello: command not found
[root@localhost hello]#

不知道是什么原因？？？？？

试一下把run-hello里面的hello -qws 改为/opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/bin/hello -qws

设成绝对路就找到了。

谢谢你的帮助~~~

谢谢楼上的兄弟

   我也是同样的问题,按四楼的办法改成绝对路就可以, 还没弄明的为什么, 要多修行想想了

我也遇到相同问题，谢谢大家的解答。

难道非要我装FC9.0
