Compiling Tauri on Ubuntu 20.04

[d4rckh]

I need to compile my game which is an tauri app for release on Steam. Linux games on steam run in a runtime based on debian 11. When I run my app right now I get these errors:

app: /usr/lib/pressure-vessel/overrides/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by app)
app: /usr/lib/pressure-vessel/overrides/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by app)
app: /usr/lib/pressure-vessel/overrides/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by app)
app: /usr/lib/pressure-vessel/overrides/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by app)

the glibc version used on debian 11 and in the steam runtime (3.0) is 2.31. I need to be able to compile against this version.

I set a Ubuntu 20.04 VM but on compiling I have a lot of missing dependencies and libraries:

I was able to compile glib and compile it on my system against glibc 2.31 but there are other dependencies required.

Also I noticed I dont have libwebkit2gtk-4.1-dev available on ubuntu 20.04

Out of curiosity, do you have to use the steam linux runtime? Never really looked at anything linux in steam, only windows.

Assuming you have and/or want to use that runtime, you'll either have to stick with tauri v1 until they offer a newer debian version or until we have an alternative to webkitgtk in place, or compile webkitgtk yourself. probably doesn't help that much but still, here's how you'd build 4.0 in flatpak https://github.com/flathub/in.cinny.Cinny/blob/master/in.cinny.Cinny.yml maybe you can use some of it as the base (official webkitgtk docs are probably better)

[d4rckh]

Do I not need to build 4.1 to use the older glibc?

And yes, I do need to use the runtime, even the steam client uses the runtime, it's so they make sure all games run in a predictable environment

I tried compiling an empty tauri project w/ react on Ubuntu 20.04 but I get the same gdk error

[FabianLars]

ubuntu 20.04 is the same as debian 11 in that context as it doesn't have webkitgtk 4.1 either - kinda relevant discussion #9662 (title is the other way around but discussion covers both)

[d4rckh]

I was able to run and compile after installing the packages, I was getting only one error inside the steam runtime:

tauri-app: symbol lookup error: /home/handrei/.local/share/Steam/steamapps/common/Mathbits/squashfs-root/usr/lib/libpangoft2-1.0.so.0: undefined symbol: hb_ot_metrics_get_position

I fixed by copying the /usr/lib/x86_64-linux-gnu/libharfbuzz.so.0 from my host inside the AppImage. How can I automate this?
