简介
嵌入式Linux中运行qt程序提示下面的错误:
This application failed to start because it could not find or load the Qt platform plugin “linuxfb”
in “/usr/plugins/”.
原因是程序找不多linuxfb这个插件,配置下插件的查找路径就可以了。
解决办法
export QTDIR=/usr
export QT_QPA_FONTDIR=$QTDIR/lib/fonts
export QT_QPA_PLATFORM_PLUGIN_PATH=$QTDIR/plugins/
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export QT_QPA_PLATFORM=linuxfb:fb=/dev/fb0:size=800x600:mmSize=800x600:offset=0x0:tty=/dev/tty1
QT_QPA_PLATFORM_PLUGIN_PATH设置为Qt plugins的真实路径。
