Not compiling on Linux

[bynelus]

Let me kick off by saying what a great framework Neo4j-swift is to work with. I got it working quite fast and didn't have issues at all. While I'm now ready to push code to production, I get errors during building of my docker image. I think it has something to do with Bolt, but can't find the origin. Maybe good to mention that I use it with Vapor 4. 🙆

Do you have an idea where it fails?

Build commando (on m1 chip):
docker buildx build . --platform linux/amd64 -t {source}:{tag} --push

Hi Niels, Thanks for the kind words. I haven’t built using Docker, but that sounds like a use case that absolutely should go into the test pipeline, so let’s get started on that. :-) Could you provide me with a minimal little project, no real hostname/username/password, to get more or less where you are? A little GitHub repo that I could check out and run your docker command would be really nice :-) Cheers Niklas

Sounds awesome man! I would really love to get this working. ✨

Here is a clean vapor project. I created a plain vapor application and added the Neo4j swift driver in the Package.json file. Then I run the following docker command: docker buildx build . --platform linux/amd64 or if you're not a silicon chip: docker buildx build .

Maybe good to mention that I use the dev/5.2.1 branch from the Neo4j-Swift package, since it has the latest developments with NIO.

I've tested it with the package: it fails building. When I leave the package out it does build succesfully.

Hope this helps! Thanks a lot for already for looking at it 🙌

I think I found the problem. It seems to be with the dev/5.2.1 branch. For the new Certificate Validators there is no Linux implementation yet nor is there for the NIOTSConnectionBootstrap. Is there a way you could help me setting this up?
