在sus11上离线安装5.6版本Qt（论坛上下载），安装完成后，双击creator 没反应，shell下运行 ./qtcreator 出现如下提示：
This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb.
Reinstalling the application may fix this problem.
已放弃
在gcc-64/plugins/platforms文件夹下能找到libqxcb.so。ldd libqxcb.so只有libEGL.so.1=>not found
这个库文件要从哪里弄啊？
PS：安装情况，这样安装是否有问题？linux-uuhua:/opt # chmod a+x qt-opensource-linux-x64-5.6.0.run
linux-uuhua:/opt # ./qt-opensource-linux-x64-5.6.0.run
