Error: Can't create a renderer

I used the examples of VisionWorks in the official system comes with its own tutorials. cd /usr/share/visionworks/sources
Then I installed the required environment: sudo ./ -/
cd -/VisionWorks-1.6-Samples
Then complie.
And when I run as follows:sudo ./nvx_demo_feature_tracker_nvxcu
I meet a error:
j@j-desktop:/user/VisionWorks-1.6-Samples/bin/aarch64/linux/release$ ./nvx_demo_stereo_matching
VisionWorks library info:
VisionWorks version : 1.6.0
OpenVX Standard version : 1.1.0
