Test case errors while running Example VxTest suite

[srini1981git]

Hi, We downloaded the latest available openVx sample code (openvx_sample_1.2.tar.bz2), built the sample libraries and ran the generated unit test executable as listed in the README file (..\openvx_sample_1.2\openvx_sample\README) . Note that our environment is Linux. On running the executable, the log is as follows :

                Note in the above failures list (all 16 of them) that the error status is always -12 (i.e VX_ERROR_INVALID_REFERENCE) . Can someone please throw some light on what could be leading to this error for the 16 example blocks? Your help is much appreciated.

Thanks, Srinivas

@srini1981git, there appears to be an issue in vxUnloadKernels. Can you try commenting out lines 135 and 136 in vx_reference.c:

          if (ownRemoveReference(ref->context, ref) == vx_false_e)
            {
             // status = VX_ERROR_INVALID_REFERENCE;
             // return status;
            }
