Add org.freedesktop.Sdk.Extension

[teohhanhui]

This should make Sdk extensions available.

What's broken that this tries to fix?

But I've been unsuccessful in getting this to work thus far... 😞

This causes the installed org.freedesktop.Sdk.Extension.* runtimes to be mounted under /app/lib/sdk. I guess that'd have to do? It doesn't seem like it can be /usr/lib/sdk since /usr is only reserved for runtimes, according to flatpak docs.

[nanonyme]

Did you try adding it to add-extensions?

[nanonyme]

Not that it necessarily works. It might have runtime deps not in Platform.

[teohhanhui]

Did you try adding it to add-extensions?

Yeah, that's the first thing I did. It's unnecessary, since inherit-extensions does the same thing without duplicating the config here.

Not that it necessarily works. It might have runtime deps not in Platform.

export PATH="$PATH:/app/lib/sdk/dotnet5/lib"

works for me. (dotnet binary is in lib lol)

[gasinvein]

If this has to be manually added to PATH anyway, why not just run Steam via flatpak run --runtime=org.freedesktop.Sdk com.valvesoftware.Steam and have the SDK extension mounted at the usual place?

That's of course the very first thing I've tried. It does not work at all.

It breaks Steam because for some reason the i386 compat runtime doesn't work properly with that.

[gasinvein]

Do you have org.freedesktop.Sdk.Compat.i386//21.08 installed and up to date?

[teohhanhui]

Do you have org.freedesktop.Sdk.Compat.i386//21.08 installed and up to date?

Yes, Running without the --runtime flag works.

I think this is because the add-extensions calls actually add extension points to the app's runtime (overlay filesystem?). So changing the runtime means those extension points are not there, i.e. they're not in org.freedesktop.Sdk runtime.

[gasinvein]

Running with --runtime=org.freedesktop.Sdk does work here. Can you please show what flatpaks you have installed (e.g. flatpak list --columns=ref)?

I think this is because the add-extensions calls actually add extension points to the app's runtime

No, add-extensions always adds app extension regardless of what runtime is in use.

So you actually don't have org.freedesktop.Sdk.Compat.i386//21.08 installed. Try installing it and running Steam with --runtime=org.freedesktop.Sdk after that.

[teohhanhui]

Uhh... Sorry, I've misread your comment. I thought it was the usual org.freedesktop.Platform.Compat.i386//21.08

[teohhanhui]

Thanks. That works. Now if only there's flatpak override --runtime 😞

[teohhanhui]

What do you think about switching the runtime to org.freedesktop.Sdk? I'd imagine that using mods is a fairly typical use case. This would make it so much easier.

The user would then just have to set the game's launch options to e.g.:

PATH="$PATH:/usr/lib/sdk/dotnet5/bin" %command%

Or we could also support FLATPAK_ENABLE_SDK_EXT like many flatpak'ed IDEs do:

https://github.com/flathub/ide-flatpak-wrapper/blob/919677ff0a9bc7f49eda6163ead97171df360c42/vscode.sh#L48

[gasinvein]

Now if only there's flatpak override --runtime

You can override the flatpak .desktop file by copying it to ~/.local/share/applications/ and editing the Exec= line.

Yeah, I know, but it's tedious. Haha... Every time that desktop file changes, I'd have to keep an eye on it.
