Include EGL

[TheDrawingCoder-Gamer]

Includes EGL as a dependency. Wayland needs this dependency to use LayerGLSkija.

[TheDrawingCoder-Gamer]

converting to draft bc this is going to be more complex than anticipated

[tonsky]

Ok let me know when it’s ready to merge

[TheDrawingCoder-Gamer]

Ready to merge - much less complex than anticipated.

[tonsky]

Please take a look https://github.com/HumbleUI/Skija/actions/runs/7145633086/job/19461717870

[TheDrawingCoder-Gamer]

Bumping version, works on my machine. Maybe lack of dependencies?

[tonsky]

Yeah, which ones?

[TheDrawingCoder-Gamer]

Unsure, maybe EGL version is outdated? My local version is 1.1.0 (with an archlinux package version of 1.7.0 for libglvnd). If it were missing though, it shouldn't be able to build.

[TheDrawingCoder-Gamer]

It looks like others have to pull in libEGL: https://github.com/BlGene/egl_check/blob/master/.github/workflows/c-cpp.yml

(which makes sense - you already have to install mesa for normal gl)

[tonsky]

What’s the name of the dependency? To add here https://github.com/HumbleUI/Skija/blob/856859e51be59ba52dc498744e7efaf3d1b94567/.github/workflows/build.yml#L50-L53

libegl1-mesa libegl1-mesa-dev I think.

[tonsky]

Still doesn’t work

[dzaima]

dpkg-query -S /usr/lib/x86_64-linux-gnu/libEGL.so gives libegl-dev for me, so that maybe? Unsure though, weird that it compiles but then fails to run.

[tonsky]

still no, same error

[TheDrawingCoder-Gamer]

It's possible EGL is like GLX, although I had thought that it was more compatible. You may have to pull in stuff.

Maybe mesa-utils-extra?

this is why I don't like CI : (

[tonsky]

this is why I don't like CI

Why? Because you have to spell out every dependency? What other way is there? Building it on your own computer?

[TheDrawingCoder-Gamer]

it's a lot of trial and error for something that takes 30 minutes to run

[tonsky]

I think you should be able to enable github actions in your fork and play with the dependency name there. The environment should be the same, sans secrets (these are only needed for publishing, so shouldn’t be a problem)

[TheDrawingCoder-Gamer]

https://github.com/TheDrawingCoder-Gamer/Skija/actions/runs/7213144238/job/19652346199#step:4:108 it seems that it isn't linked in at build time?

pacman -Qo /usr/lib/libEGL.so returns libglvnd - but I download libglvnd-dev : /. is it possible that it never actually looks in /usr/lib? https://packages.ubuntu.com/focal/amd64/libegl-dev/filelist this is the file list of libegl-dev.... /usr/lib/x86_64-linux-gnu/libEGL.so.... this doesn't really make sense tho. No idea why it's pointing into /lib and not /usr/lib.

[TheDrawingCoder-Gamer]

ld can still find libEGL, so it's defo installed. No idea why it's missing a link. Notably, I also have libEGL_mesa installed but this isn't required in any way. This SHOULD be working but for some reason it just... isn't? Again this is why I don't like CI, trial and error where each trial takes 5 minutes, instead of the 1 minute for local builds.

[TheDrawingCoder-Gamer]

ldconfig says that yes, EGL is installed?

    libEGL_mesa.so.0 (libc6,x86-64) => /lib/x86_64-linux-gnu/libEGL_mesa.so.0
    libEGL.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libEGL.so.1
    libEGL.so (libc6,x86-64) => /lib/x86_64-linux-gnu/libEGL.so

[TheDrawingCoder-Gamer]

It also finds EGL while linking, but it finds it in /usr/lib/x86_64-linux-gnu/libEGL.so

No idea why ldd says it isn't linked. It SHOULD be linking.

also, I can't actually build locally without including <cstdint>. No idea what is different, I'm trying to install gcc-9 rn to try to use the correct gcc version.

[TheDrawingCoder-Gamer]

!!! You have to link it in earlier.

Look at changes to the FindSkia cmake file and CMakeLists file.

Works for me : )

[tonsky]

Ok I published 0.116.2, let me know if it works for you and if it does, please close this PR

[TheDrawingCoder-Gamer]

Yep, works locally. Closing.
