Support additional architectures

[jonmmease]

Right now we are building Kaleido on 64-bit MacOS, Linux, and Windows. Folks may eventually be interested in builds for other architectures.

In addition to those above, it looks like Chromium also supports 32-bit Windows and Linux, and 32-bit ARM.

If you're interested in helping out with adding support for an additional architecture, please chime in here!

Hi. Today I tried to install kaleido on my Raspberry Pi running Ubuntu and found this issue after not succeeding.
The out put of

import platform
print(platform.machine())
print(platform.architecture())
print(platform.platform())

is

aarch64
('64bit', 'ELF')
Linux-5.4.0-1015-raspi-aarch64-with-glibc2.29

TBH I don't have a clue of architectures, hardware etc, but if there is anything I can do, I'll be happy to help bring kaleido to raspi :)

Hi @Bibo-Joshi, thanks for reaching out and providing that info! I'm not very familiar with arm architecture flavors, but it looks like chromium does support build targets for arm and arm64: https://www.chromium.org/chromium-os/how-tos-and-troubleshooting/chromiumos-board-porting-guide.

And pip packages support armv7l and aarch64 platform tags: https://packaging.python.org/specifications/platform-
compatibility-tags/

Based on the result of platform.machine, it looks like you would need the arm64 chromium build and the manylinux2014-aarch64 platform tag.

It looks like a pretty simple change in the CI configuration to build for arm, but I don't have anything set up to test on. If you're interested in trying out a test build, I think I could at least try building one on CI at some point over the next week or so.

Thanks for the quick reply!

Yes, absolutely :)

Update: As of 0.0.3.post1, win-32 and linux-arm64 builds are available in addition to win-64, linux-64, and macos-64.

Some other architectures that could potentially be supported in the future:

• win-arm64: https://chromium.googlesource.com/chromium/src/+/master/docs/windows_build_instructions.md
• linux-arm (32-bit I think): https://chromium.googlesource.com/chromium/src.git/+/master/docs/linux/chromium_arm.md

Closing in favor of dedicated issues for each architecture
