Cross Compiling suggestion

[daoudeddy]

The issue:

I've been working on a project of mine for Home Assistant when I encountered a problem with cross compiling ZeroNS caused by openssl not found for cpu architecture other than the host

The fix:

Maybe this is my first time building a rust project, the way I fixed it is by adding to the dependencies

openssl = { version = "0.10.38", features = ["vendored"] } build successed and tested on Ubuntu amd64 for Alpine amd64

Is it something you can implement it in this project?

Hmm. Not sure how well this'll work with the different packages, but I'm willing to try it out!

[daoudeddy]

Okay thank you

[erikh]

I think you misunderstood me. Let's try it, see how it works. I'll report back here once I have. Let's leave this open until I do.

Please note this didn't work as well as I'd hoped: #177 resolves some issues with this. You'll need to use this method to install zeronsd on your hosts. Hope it helps!

[daoudeddy]

Thats a great news, I'll test it in my project and report back, thank you again.

Edit: Working perfectly, thank you

Cross compile re-broke after version 0.5 with the same error as before the fix you implemented while running

cargo build --features vendored-openssl

With the following error:
