Building Chromium and using Reclient on ARM linux

[Yoav Weiss (@Shopify)]

Hey folks!

I'm trying to optimize my Chromium workflow and would love some advice.

Currently I'm building Chromium on a cloud amd64 Linux VM, and using reclient.

That works.. fine, but at the same time I'm unhappy with the machine's local I/O performance, it's an expense to continuously justify and I don't have that env when I'm offline.

So I thought I can try to improve on that by installing a Linux VM locally, on my M1 MBP.

As it turns out, running amd64 Linux on M1 (in emulation mode) is extremely slow. So I'd like to try and build Chromium on ARM Linux, while using Reclient.

But when I tried that, I ran into issues where `gclient runhooks` didn't pull in the right `gn` binary, and it was unclear if reclient even supports that configuration.

Can y'all confirm if this is at all possible? Anyone else that has tried a similar setup?

Cheers :)

I think you will run into a lot of missing things right now.

https://source.chromium.org/chromium/chromium/src/+/main:DEPS?q=f:%5Edeps%20rust

Take a look at all the `linux-amd64` in this file, and note how there's no `linux-arm64` equivalent for most if not all of them. Compare that to `mac-amd64` and `mac-arm64`.

Agreed. I wouldn't consider Linux ARM a supported platform. There's no gn binary. I'm not sure what all else is missing, but I'm sure there are other things.
