IMX6DL 运行qt程序提示This plugin does not support createPlatformOpenGLContext! Aborted

针对i.MX6的板子，系统运行正常。原系统使用qt4.8.5（不含opengl），因qt应用层软件功能需求需要opengl，因此自己交叉编译了qt5.4.1的源码并将其配置到imx6板子上，在运行测试程序时出现如下错误信息：

# ./TestAnimation -platform linuxfb

在qt官方给出的一篇文章中发现（http://doc.qt.io/qt-5/embedded-linux.html）：

Building Qt for a given device requires a toolchain and a sysroot. Additionally, some devices require vendor-specific adaptation code for EGL and OpenGL ES 2.0 support. This is not relevant for non-accelerated platforms, for example the ones using the LinuxFB plugin, which is meant for software-based rendering only.

因此我采用platform eglfs，qt5.4.1源码交叉编译配置方法如下：

vim $source_path/qtbase/mkspecs/linux-arm-gnueabi-g++/qmake.conf

#
# qmake configuration for building with arm-linux-gnueabi-g++

qt5.4.1源码congiure配置如下：

在运行测试程序时出现如下错误信息：

libEGL warning: DRI2: xcb_connect failed

请教下是否在配置qt5.4.1源码时未配置正确？希望各位能提供下qt5编译的方法，谢谢！

你好：

我参考你给的链接按照其中的方法配置后，执行我的测试程序，出现如下输出信息。我发现使用上面的qt配置只有运行使用linuxfb qt程序才可以成功运行，但是使用到opengl、qml时就失败了。

Could not open display
Aborted

root@freescale /$ ./TestAnimation -platform eglfs
Could not open display

还望你能进一步讲解下，十分感谢！
