用opengl实现图形加速计算，出现了上述的错误，能否给出解决方法？

    另外我们主要想在offscreen的无显示平台下运行带有OpenGL组件的程序比如cube、2dpainting等等，但是出现下面的问题：

    root@TK-AQ-REC-XJT-AM5718:/usr/share/examples/opengl/cube# ./cube -platform offscreen
QOpenGLWidget is not supported on this platform.
This plugin does not support createPlatformOpenGLContext!
This plugin does not support createPlatformOpenGLContext!
QOpenGLWidget: Failed to create context
This plugin does not support createPlatformOpenGLContext!
QOpenGLWidget: Failed to create context

    是否可以让offscreen平台支持OpenGL的组件？怎样做？谢谢！

    您好

    您使用的是哪个SDK版本？

    使用的是ti-processor-sdk-linux-am57xx-evm-08_02_01_00这个版本的SDK

    您好

    您可以更新到最新的9.03 SDK吗？8.2版本的GPU驱动程序已经过时，有许多错误可以通过更新到最新的SDK版本来避免。

    现在不能更新SDK，还是要在8.2版本的基础上解决，我们现在不用（eglfs）方式了，想先用（./cube -platform offscreen）这个方式执行程序，有什么办法可以解决一下的这个问题？

    您好

    您是否能够通过运行systemctl stop weston来解决此错误，如本文所述？

    您对SDK文件系统进行了任何更改吗？您是否使用默认的SDK 8.02 KM和UM二进制文件？
