Hi there!  
  
  
  
I downloaded full SDK 3.1 for arm / linux but there are no hard float libs for armv7 in /opt/Imagination/PowerVR/GraphicsSDK3/SDK\_3.1/Builds  
  
  
  
Found only some libs in /opt/Imagination/PowerVR/GraphicsSDK3/PVRTrace/Recorder/Linux\_armv7hf but they linked with libPVRTrace.so

Hi,  
  
  
  
For our 3.1 SDK, we only added hf support for our utilities. Our 3.2 SDK will have hf support for all of our Examples.  
  
  
  
You can easily work around this . Instead of linking to libraries in SDK\_3.1/Builds/, you can link directly against your target’s hf graphics libraries.  
  
  
  
Regards,  
  
Joe

My target is Odroid XU and it doesn’t have yet official GL libs for linux. Just thought maybe raw GL without X11 may work using vendor libs. Thanks.

Hi,  
  
  
  
Apologies. I misunderstood your original question. Our SDK does not contain graphics drivers. You must contact the platform provider for graphics driver support.
