ovr_CreateTextureSwapChainGL() failed
So every tine I attempt to create the swap chains, I got the error code ovrError_InvalidParameter == -1005 with the following message returned by ovr_GetLastErrorInfo():
BindFlags not supported for OpenGL applications.
I am using Oculus DK2 with the SDK 1.20 and latest NVidia drivers. This issue started many months ago, probably since 1.12 or so.
The code is a direct copy-paste from the OculusRoomTiny (GL) sample, or from the Texture Swap Chain Initialization documentation:
The initialization sequence is following (I am skipping error checks for clarity):
So according to the error message, SDK thinks that I am assigned something to desc.BindFlags, while I am not. I tried to directly assign ovrTextureBind_None value to it (which is just zero), but still no success. I traced all variable values in debugger, they are the same as is the OculusRoomTiny (GL) sample. The only difference in my code that I can see is that I am using GLEW library to handle OpenGL extensions, while sample uses OVR::GLE. It initializes it immediately after wglMakeCurrent():
Can this be the cause? But I don't want to switch to Oculus' extensions library. My project is not Oculus-exclusive, it supports Vive and non-VR modes as well. If it is a bug inside libovr, I request Oculus team to fix it!
