Ways to test Weston during development (Re: Full-motion zero-copy screen capture in Weston)

[Hoosier, Matt]

Would Meson’s dependency wrapping capabilities be a viable solution here? I think that most of Weston’s dependencies that have aggressive version requirements are themselves also Meson projects.

The Weston CI configuration builds a bunch of its dependencies (Mesa, libdrm, libwayland …) manually. I wonder why Meson wrapping was not used for this?

Thanks, everybody.

After some trial and error, I find that if I install seatd in the host and the seatd dev package in the Toolbox container and I then symlink the host seatd socket into /tmp on the container, Weston seems to start up okay on my physical KMS connectors:

user at host:~$ toolbox enter
…

user at toolbox:~$ sudo ln -s /run/host/run/seatd.socket /run/
user at toolbox:~$ weston --backend=drm

Yes, doing it in containers is a little bit tricky since it's not

exactly the design case. Honestly, on my Silverblue systems, I just

install a bunch of relevant dependencies into the system image with

rpm-ostree, and have a pile of self-built dependencies in a local

prefix.



This might give you some insight however:

It probably needs some minor changes in Weston but does at least seem doable ...
