I didn't do a universal build yet, I can test that next, but arm compile support of the Python library is now in with #462

hi @jesterKing we would like to use the library with a raspberry pi model 4 b. Is there some known way to compile it to arm64?
Thank you in advance!

[jesterKing]

@mit200 I have to break out my rpi4 and fiddle around a bit, but in the meantime have a look at mcneel/opennurbs#13 and make the changes locally.

@jesterKing thanks for the input! Sadly, I don't have the environment since I'm using it for a .NET project. Tried some stuff out but wasn't really able to get it going (I'm getting a cmake compile error on my windows system since arm is configured). Is there any way you could provide a prerelease with compiling it for ARM? Happy to test it out :)

[jesterKing]

I don't know how to cross-compile this on Windows for rpi4. My rpi4 hardware is currently still somewhere in boxes, it'll be some time before I get to it.

You could try finding ways to emulate an arm64 system so that you could install the raspberry os and compile via that.

@jesterKing sounds good thanks! In the meantime we'll try it on our rpi4 or maybe emulate an arm64 with docker and provide feedback.

With the 8.0.0 release we've added universal binaries for macOS .net builds. At this time there are no arm64 linux runners available on GitHub. I'll create a new issue for this.
