NetBSD now complains:

as does freebsd and openbsd. Can we get the theme added to the VM
configs for those ?

What is used for the BSD configs? If it's tests/vm, I don't see readthedoc
being installed there, and vm-build-* should work (at least some work for
me, freebsd fails with ssh issue here)

It's tests/vm.  The build doesn't fail, but the printing of the WARNING
is caught by my wrapper scripts (which grep for various warning/error
words to catch issues which don't trigger complete build failures).
Adding the theme to the configs would mean that we can continue to
test docs builds on those platforms.

Didn't you install readthedoc manually there? I don't see those warnings.

No, I don't install anything manually on the BSD VM setups -- I just
use the tests/vm makefile magic to run a build-and-test.

I've figured out what was going on here, and it was my mistake;
I didn't look at the logs closely enough. When my scripts run
'make vm-build-netbsd' or whatever, this can trigger a configure
run in the host, which is what is producing these warnings.
The host makefile then goes on to launch the BSD VM and the
inner configure run inside the VM is fine (as you note it doesn't
have sphinx installed, so no docs are built.)

I should be able to deal with this by installing the rtd theme on
the host. I'll retry merging the pullreq.

On try 2 I find that some of my machines warn:

Program qemu-keymap found: NO
Program sphinx-build found: YES
../../docs/meson.build:30: WARNING: /usr/bin/sphinx-build:
Theme error:
unsupported theme option 'style_nav_header_background' given

Program python3 found: YES (/usr/bin/python3)
Program diff found: YES

It looks like this is because it's trying to use an option
that's only present in newer versions of the theme. (Ubuntu
bionic has version 0.2.4 of the rtd theme.)

Is it possible to either avoid or conditionalize the use of
this config setting?

thanks

However, we agreed before to not have support fallbacks for missing deps.
Perhaps we should require rtd >= 0.4.3 instead?

This fails:

That would prevent the docs from building on too many platforms,
I think. 0.4.3 was only released upstream in Feb 2019.
