Short Description of the issue

https://github.com/interTwin-eu/interlink-docker-plugin/blob/main/README.md?plain=1#L88

After setting CGO_ENABLED to 0 I am getting the following error

CGO_ENABLED=0 GOOS=linux go build -o bin/docker-sd cmd/main.go

Steps to reproduce

Clone this repo and run CGO_ENABLED=0 GOOS=linux go build -o bin/docker-sd cmd/main.go.

@Bianco95 I think cgo is needed cause of nvidia library, is it really possible to build it this way? or this is true only for the non-GPU branch?

[Bianco95]

Yes @dciangot , it is true only for the non-GPU branch. Thanks @waveywaves for highlighting this misunderstanding. In fact, before executing that command to compile the plugin without using the GPU, it is necessary to switch to the branch
2-light-version-no-gpu.
