OpenCV Error: Gpu API call (invalid device symbol) in buildPointList_gpu
Hi guys, I followed the instructions from here:
http://elinux.org/Jetson/Installing_O...
With the exception that I built OpenCV v3.1 and also opencv_contrib.
I could run the cpp samples - edges.cpp without any problem.
However, when I run gpu sample, I am encountering this error:
<-----COMMAND HERE -->
ubuntu@tegra-ubuntu:~/opencv3/opencv/samples/gpu$ ./houghlines ../data/pic1.png
<-----OUTPUT HERE -->
CPU Time : 7.13239 ms
CPU Found : 12
OpenCV Error: Gpu API call (invalid device symbol) in buildPointList_gpu, file /home/ubuntu/opencv3/opencv/modules/cudaimgproc/src/cuda/build_point_list.cu, line 116 terminate called after throwing an instance of 'cv::Exception' what(): /home/ubuntu/opencv3/opencv/modules/cudaimgproc/src/cuda/build_point_list.cu:116: error: (-217) invalid device symbol in function buildPointList_gpu
Aborted
<------ END OUTPUT ------>
I have checked that my CUDA in nvidia TX1 is actually working by running NVIDIA Cuda 7.0 samples.
