when i compile the code, i got this error, it seems like trying to get a Runtime library which i cannot find in directory, i added set(CUDA\_USE\_STATIC\_CUDA\_RUNTIME OFF) in the CmakeLists.txt but it’s not working. How do i include this opencv\_dep\_cudart in cmakelists? ---

Maybe some dependent lib wasn’t installed.

The actual problem is that ld is asking for “-lopencv\_dep\_cudart” There is no library named “opencv\_dep\_cudart.” There may be a pkg-config or cmake token named opencv\_dep\_cudart, which is supposed to resolve to the appropriate .so file, but that’s not happening here. The bug is not in the paths or search paths for libcudart.so; the bug is in the cmake build system support files for cuda, or perhaps with how your CMakeFile.txt is set up (but I’ve seen correct CMakeFiles break like this.) A short-term hack that fixes this for me is the following patch: ```auto --- /tmp/unpatched 2017-07-27 05:35:44.164961655 +0000 +++ /usr/share/OpenCV/OpenCVConfig.cmake 2017-07-27 05:34:06.129390969 +0000 @@ -281,6 +281,11 @@ set_target_properties("opencv_dep_${_tmp}" PROPERTIES IMPORTED_LOCATION "${l}") endif() endforeach() + + # HACK jwatte 2017-07-26 trying to find the dynamic library + add_library("opencv_dep_cudart" UNKNOWN IMPORTED) + set_target_properties("opencv_dep_cudart" PROPERTIES IMPORTED_LOCATION /usr/local/cuda-8.0/targets/aarch64-linux/lib/libcudart.so) + endif() # ============================================================== ``` ---

You have to add “set(CUDA\_USE\_STATIC\_CUDA\_RUNTIME OFF)” in CMakeLists.txt, or code in shell as this ： cmake -DCUDA\_USE\_STATIC\_CUDA\_RUNTIME=OFF ---

For Openvx tutorial after setting the syntax in CMAke file, I got no error except, video cannot open. Since it has an output video which it is not able to open. What could be the reason behind this ? ---

Aastha, I specifically want to use Openvx in jetson so i started learning it from Openvx\_tutorial but when it didnt run, i started working on Opencv. but my preference is Openvx, also i would like to have some good material related to openvx to learn it if you know. that would be greatfor me. ---

Hi, We have lots of samples to demonstrate OpenVX. (We call this VisionWorks API, specifying for Nvidia implementation) Please install VisionWorks with JetPack directly. Samples are located at /usr/share/visionworks/sources. Most samples contain video decoder, for example, demos/feature\_tracker. > **[Vision Programming Interface (VPI)](https://developer.nvidia.com/embedded/vpi)** > > Helps developers to solve challenges when working with Jetson embedded devices. ---

Hi, Please share OpenVX sample and error message for us debugging. One possible reason is not correctly linking to VisionWorks libraries.
