Why are extensions from the add-extensions: section not automatically downloaded via the flatpak-builder --user --repo=local --force-clean --install-deps-from=flathub command?

Here’s a piece of my manifesto

sdk: org.gnome.Sdk
runtime: org.gnome.Platform
runtime-version: "45"
command: portproton
separate-locales: false

sdk-extensions:
   - org.gnome.Sdk.Compat.i386
   - org.freedesktop.Sdk.Extension.toolchain-i386

finish-args:
  - --share=ipc
  - --socket=x11
  - --socket=wayland
  - --device=all
  - --share=network
  - --allow=multiarch
  # For Wine crash handling
  - --allow=devel

When I run flatpak-builder it does not install org.gnome.Platform.Compat.i386, org.freedesktop.Platform.GL32.default, org.freedesktop.Platform.ffmpeg-full and org.freedesktop.Platform.ffmpeg_full.i386 what could be the reason for this behavior ?

Those are runtime extension points, not anything required for build. I’d expect the autodownload extensions would be installed when you actually install the app.

3

I solved this error by just pre-installing the right stuff, but now I get this error on startup

bwrap: Can’t mkdir /app/lib/ffmpeg: Read-only file system

4

Create that folder on build?

I looked at how it’s done in wine and heroic and it didn’t have those folders, but I’ll try to create them, thanks for the tip, I’ll post if it works out

Thank you for help its worked
