ARM architecture support

[OkenKhuman]

I was trying to build the the image for RPi4b but unfortunately end up with error.

Please add build instruction/ images for ARM/v6

Hi @OkenKhuman - thanks for opening this issue. Mind providing a bit more information such as OS/Docker version/the errors you are seeing?

[OkenKhuman]

I'm very sorry for this late reply

The problem was on line no. 15/16

@juniorxsound I'm also trying to work with this image in the new macbook with M1 chip, and it's not possible. Here is the problem:

Thanks for the info @agusmdev, hoping to try to find an M1 MB I can replicate this on - are you using Docker Apple Silicon Tech Preview?

Yes! exactly. I've tested several other things and docker itself seems to be working correctly, but I couldn't make blender work

[juniorxsound]

Hi @agusmdev wanted to circle back on this and ask - we just published new images for Blender 2.93 would you be able to test these new images?

[agusmdev]

Thank you @juniorxsound for coming back, I tried to run with the new image but I wasn't able to do it, this is the error

[juniorxsound]

Thanks @agusmdev. I am still trying to get a machine I can replicate this on - will keep you posted on progress.

I am trying to build Blender 2.93 on Nvidia Jetson Nano, it's simply failed when missing SSE2. It's not an easy task for porting blender to ARM for myself. And waiting is an option for me. Finally, @juniorxsound excellent work for this repo.

Updates: But we can use Blender 2.82 on Ubuntu 20.04, just apt install -y blender

Hello! First of all, thank you for such a fantastic project! I have the same problem. MBP M1 2020. any updates on this? I tried running 3.3.1-cpu-ubuntu18.04

Thank you @juniorxsound for coming back, I tried to run with the new image but I wasn't able to do it, this is the error
