after having gone through the Visionworks samples, I am a little stuck trying to understand how linking against the Visionworks library works. I am working on a Jetson TX1 with Visionworks installed. I was able to successfully build all the Visionworks samples.
Now I am looking for a way to include the nvxio library in my standalone code, however, I am unsure what I have to set up in my CMakeLists.txt file. I would imagine, I have to first find_package the library and then include it in the include_directories and lastly link against it with link_directories.
Are there any examples for doing this available? The Makefiles are overly complicated and I am not sure I fully understand what they are doing and how everything needs to be set up for this to work. Do I need to copy the nvxio folder into my CMakeSourceDirectory?
kayccc,
I’ve installed JetPack 2.3 to my Desktop & TK1 board.
My TK1 setup:

But visionworks library is compiled against cuda-8.0:
I can see the JetPack 2.3 contains different visionworks versions for armhf and amd64 targets. Is it possible to include the same VisionWorks versions for armhf & amd64 in the JetPack distro?
Well, could you please rebuild libvisionworks-1.5 against cuda-6-5 for amd64 and armhf for TK1 please.
Would be nice to have it in the next JetPack release.
Thanks!
We do not offer the 64-bit user space and runtime libraries for TK1, and the JetPack also only run on 32-bit Ubuntu 14.04.
You may need to manage to use a virtual machine with ubuntu 14.04 instead of real host.
