[Build] Missing header (gstgldisplay_egl_device.h)

[markusbkk]

Attempting to build (yarn build:native) the compositor-proxy fails with the following trace:

I hooked into vcpkg and it didn't find any missing packages, so this must be some sort of version mismatch?

Yes indeed, ubuntu 20.04 uses gstreamer 1.16 while the required header is in gstreamer 1.18. I'll see if I can make the version requirement more strict.

Thanks! That helped.

For anybody else running into this issue, they can update GStreamer through a PPA.

sudo add-apt-repository ppa:miurahr/gst
sudo apt update
sudo apt-get install gstreamer1.0-tools gstreamer1.0-alsa gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav

Still running into issues launching the proxy and module at the same time (somehow, one of the two will connect to the wrong port), but that's probably just my own device being wonky RN. Nothing a reboot can't resolve.

PS: The documentation says to copy app-endpoint-encoding.node. Shouldn't it be proxy-encoding-addon.node?

Good catch. That was renamed not so long ago and the documentation was not updated it seems. I'll fix that.

I've written up a short "tl;dr" set of commands starting from a vanilla WSL Ubuntu 22.04 install. This works for me but I've might missed some steps while setting everything up. Let me know if anything is not working for you.

Tested using: node v18 ubuntu 22.04

Open a new terminal for running the compositor-proxy:

• sudo apt install \ cmake \ build-essential \ ninja-build \ pkg-config \ libffi-dev \ libudev-dev \ libgbm-dev \ libdrm-dev \ libegl-dev \ libwayland-dev \ libglib2.0-dev \ libgstreamer1.0-dev \ libgstreamer-plugins-base1.0-dev \ libgraphene-1.0-dev \ gstreamer1.0-plugins-base \ gstreamer1.0-plugins-good \ gstreamer1.0-plugins-ugly \ gstreamer1.0-gl \ xwayland
• yarn install
• yarn generate
• yarn build:native
• cp dist/encoding/proxy-encoding-addon.node src/encoding/proxy-encoding-addon.node
• export XAUTHORITY=.Xauthority
• touch "$HOME/$XAUTHORITY"
• xauth add "${HOST}":1 . "$(xxd -l 16 -p /dev/urandom)"
• export XDG_RUNTIME_DIR=/tmp/xdg
• yarn demo

Open a new terminal for running the compositor-module:

• yarn install
• sudo apt install openjdk-11-jre-headless
• yarn generate
• yarn demo

Open a new terminal for running the program:

• sudo apt install gtk-4-examples
• export XDG_RUNTIME_DIR=/tmp/xdg
• (optional, only required if running X11 program) export DISPLAY=:1
• gtk4-demo

Open a browser and go to localhost:8080 and click the button below that connects to localhost:8081

Thanks! Works as advertised now. Strangely, XWayland allows HandleResize events in situations in which they shouldn't and just fail silently on other X Servers.

Yeah the current X Window Manager implemented in Greenfield is not entirely EWMH/ICCCM compliant and is basically a typescript port of Weston's X Window Manager. There are definitely improvements to be made.

Microsoft's own Weston port exhibits the same behavior so I assumed this would be deeper down the stack.
