Hi,everybody

   I install Aviage HMI Suite 2.0 and Composition Manager [Patch ID 1347] on Qnx6.4.0, and write a openkode application.
 

   But, the function of kdCreateWindow can't work and the error message is "kdCreateWindow not support". 
   1.The init of EGL is ok
   2.My Display Card is : Intel G33,  and I select the dirver i830.

  For this thing , I install the QnxDsp6.4.1 and Aviage HMI Suite 2.0 and failued too.

  What can I do for it?

Thanks every much.

Re: failed to kdCreateWindow

kdCreateWindow raises the KD_ENOSYS error if the display argument does not correspond to a composited window system 
display connection, and the KD_ENOMEM error if it failed to allocate a KDWindow * for the new window.

eglGetDisplay(EGL_DEFAULT_DISPLAY) will try to establish a composition manager display connection, and will fallback to 
the null-windowing system connection with io-winmgr is not running.

I suspect you are getting this error because io-winmgr is not running.
