用的英码科技的sbc3730开发板，内核、文件系统，都是英码科技提供的，文件系统中/opt/gfxsdkdemos/ogles2，/opt/gfxsdkdemos/ogles下面的例程均可以运行。
qt-embedded-linux-opensource-src-4.5.3 + Graphics_SDK_4_03_00_02，配置，编译，安装生成带opengles2的qt，安装后复制到开发板文件系统下，把QT目录/plugins/gfxdrivers文件夹复制到开发板根目录/usr/lib下
开发板执行：export LD_LIBRARY_PATH=QT目录/lib
运行QT目录/examples/opengl/hellogl_es2/hellogl_es2
./hellogl_es2 –qws –display powervr
报错：
powervr : driver not found
Aborted
/etc/powervr.ini文件内容
[default]
WindowSystem=libpvrPVR2D_FRONTWSEGL.so
#WindowSystem=libpvrPVR2D_FLIPWSEGL.so
#WindowSystem=libpvrQWSWSEGL.so
如果注释第一行，用第三行的libpvrQWSWSEGL.so，还是报同样错误。
请问这是怎么回事？是文件系统共中powervr驱动没装好，还是我的qt没编译好呢？
附：如果用strace -f -o hellogl_es2.log ./hellogl_es2 –qws –display powervr来执行
