add cuda build for librealsense2 #1032
Conversation
|
CUDA is only available for linux-arm64, linux-ppc64le, linux-x86_64, and windows-x86_64, but it won't work with linux-arm64 and linux-ppc64le because we would need first to get the cross-compiler working on GitHub Actions, so please adjust the workflows/librealsense2.yml and platform/gpu/pom.xml files with only linux-x86_64 and windows-x86_64, for now anyway. Thanks! |

I modified to add CUDA option for only linux-x86_64 and windows-x86_64. BTW, CUDA option is originally for ARM platform because librealsense2 supports only SSE and CUDA backend, NEON is not implemented. |
|
If you would like to figure how to get the cross-compiler working for ARM, please do!
|
|
Actually I don't understand GitHub Actions at all, but I'll try to learn. |
|
No need to learn GitHub Actions. We first need to get it working, somewhere, anywhere, it doesn't matter, for now. We'll worry about GitHub Actions later.
|
|
I did build success on pure arm platform with CUDA, but I'm not sure whether we can build CUDA with cross compiling. |
|
Maybe, I don't think that it works well though. Please try to make it work either way.

I found CUDA is not supported by ARM except for Jetson. So I removed ARM build from GitHub Actions workflow, but cuda build option is left so that we can get linux-arm64-gpu.jar if we build with physical arm platform such as Jetson. |
|
CUDA does support ARM since 11.0: |
|
In any case, please fix the workflow and let's see if there are any build errors. Thanks! |
Add cuda build option
BUILD_WITH_CUDAfor librealsense2.We can get benefits of cuda for some processes such as alignment.
