请教各位x86的qt4.5有什么用啊

我按照仿照教程arm版的步骤，设置了qtcreator的在x86下面的qmake路径，
怎么编译出来的程序在Fedaro 10下运行不了呢
root@EmbedSky helloworld]# ./helloworld

No Qt for Embedded Linux server appears to be running.
If you want to run this program as a server,
add the "-qws" command-line option.
各位给出指导
谢谢了

光盘中的Qt4.5只能编绎出嵌入式的QT，如果想开发x86下的Qt需要下载qt-x11*.tar.bz2重新编绎
