Can icecc still be used to accelerate Chromium builds?

[AlphaHans]

I'm trying to use icecc to accelerate Chromium builds. Many online tutorials are quite old. I've successfully set up an icecc server node, but I keep getting errors when building Chromium. Can someone provide the latest instructions?

prepare:
icecc --build-native

I'm having trouble finding a device that's disabled on my monitor. What could be causing this?

I don't use icecc + ccache though recently, icecc for building Chromium still worked with https://chromium-review.googlesource.com/c/chromium/src/+/7106328. https://chromium-review.googlesource.com/c/chromium/src/+/7090171 broke the icecc build in Chromium recently.
