Hi,
I have been trying to implement JCuda on a NVIDIA RTX A6000 with CUDA 11.6. I was able to download the CUDA driver and toolkit library as well as install the JAR files for JCuda.
When trying to run JCudaRuntimeTest.java in the tutorial for JCuda (http://www.jcuda.org/tutorial), I was running into the following error:
Exception in thread “main” java.lang.UnsatisfiedLinkError: Error while loading native library “JCudaDriver-11.6.1-linux-x86_64”
Operating system name: Linux
Architecture : amd64
Architecture bit size: 64
—(start of nested stack traces)—
Stack trace from the attempt to load the library as a file:

I am a little confused about where to find and build these .so files for CUDA version 11.6. Any idea on how I can build these files? Thank you!
