I was wondering the same thing myself :-) This recipe lists "armv7a" in
COMPATIBLE_MACHINE but the (32-bit version of) raspberrypi3, for
example, is armv7ve. Therefore I get:

	ERROR: Nothing PROVIDES 'chromium'
	chromium was skipped: incompatible with machine raspberrypi3 (not in COMPATIBLE_MACHINE)

Okay, good to know.

Can you provide a list of "MACHINE = ..." that were used?

Maybe you're referring to "gn"? If so, it's not a show-stopper. The source
tarballs for chromium now include working sources for gn that can be built
prior to the configure step.

gn is a "makefile generator" much like the autotools. It's not the build
system itself. However, instead of generating makefiles for make (as the
autotools does), gn generates ninja files for ninja (which is the build
system, and remains unchanged from earlier versions of chromium).

The problem I was having was in trying to force the build system to use the
toolchain I wanted it to use. The Igalia people solved this problem by
tricking the build system to think it was building for CrOS, and then
redefining the toolchain for CrOS to use the toolchain generated by OE. This
worked for x86_64 (minnowboard) but would fail for the raspberrypi3 with
"illegal instruction". So somewhere in the build, the specified toolchain was
being ignored and the host's toolchain was being used instead.

I'd be happy to work on trying to integrate Raphael's excellent work into
meta-browser. However, it depends on nodejs, and nodejs is currently failing
to build (Martin's "State of Bitbake World" just exploded in the last
iteration). I'm looking into that now, somewhat. node hasn't been happy since
the switch to gcc7.

There are (now) a number of distros that make a distribution for the
raspberrypi, many of which include chromium. It would be great if it were
easy/possible to find the scripts/steps/setup they're using for comparative
reasons:
	- raspbian
	- suse
	- fedora
	- arch
	- (others?)
