zeboard交叉编译Qt5.6.0，程序运行无法加载linuxfb

[scgaluo]

使用zeboard官方的交叉编译工具，编译Qt5.6.0，程序无法运行，出错信息如下：

This application failed to start because it could not find or load the Qt platform plugin "linuxfb"
in "/usr/local/Trolltech/Qt-5.6.0-Xilinx/plugins".

Available platform plugins are: linuxfb (from /usr/local/Trolltech/Qt-5.6.0-Xilinx/plugins), minimal (from /usr/local/Trolltech/Qt-5.6.0-Xilinx/plugins), offscreen (from /usr/local/Trolltech/Qt-5.6.0-Xilinx/plugins), linuxfb, minimal, offscreen.

Reinstalling the application may fix this problem.

我指定的环境如下：

#!/bin/sh

echo "Starting qt_env.sh"

mkdir -p /usr/local/
mount /mnt/qt_lib.img /usr/local/

export TSLIB_FBDEVICE=/dev/fb0 
export TSLIB_CONFFILE=/usr/local/tslib/etc/ts.conf 
export TSLIB_CONSOLEDEVICE=none 
export TSLIB_CALIBFILE=/usr/local/tslib/etc/pointercal 
export TSLIB_PLUGINDIR=/usr/local/tslib/lib/ts 
export PATH=/usr/local/tslib/bin:$PATH 

export LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-5.6.0-Xilinx/lib/:$LD_LIBRARY_PATH
export QT_QPA_FONTDIR=/usr/local/Trolltech/Qt-5.6.0-Xilinx/lib/fonts
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0
export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/local/Trolltech/Qt-5.6.0-Xilinx/plugins/
export QT_QPA_GENERIC_PLUGINS=evdevmouse:/dev/event0
#if [-c /dev/input/event0];then
#    export QWS_MOUSE_PROTO="Tslib:/dev/input/event0 MouseMan:/dev/input/mouse1"
#fi

cd /mnt
./demo &

编译Qt过程如下：

#!/bin/sh

楼主，什么原因呀？

[qq_33673304]

你好，我想问一下您是怎么解决无法加载linuxfb 这个插件这个问题的，今天我也遇到了，要哭了

[m0_37236304]

执行程序的时候指定一下平台 ./<app-name> -platform linuxfb

[huihui343842420]

请问一下具体解决方法。
