1. Building Flatpak apps without flatpak-builder Bartłomiej Piotrowski PackagingCon 2021
2. What is Flatpak?
3. app-id: org.flatpak.Hello runtime: org.freedesktop.Platform runtime-version: '21.08' sdk: org.freedesktop.Sdk command: hello modules: - name: hello buildsystem: autotools sources: - type: archive url: https://ftp.gnu.org/gnu/hello/hello-2.10.tar.gz sha256: 31e066137(..)
4. CI is hard (and gotta go fast)
5. Let’s build a somewhat portable binary!
7. $ cat builddir/metadata [Application] name=org.flatpak.ncdu runtime=org.freedesktop.Platform/x86_64/21.08 sdk=org.freedesktop.Sdk/x86_64/21.08 command=ncdu
8. $ tree builddir builddir ├── export ├── files │ ├── bin │ │ └── ncdu │ ├── lib │ │ ├── libncurses.so.5 │ │ └── libtinfo.so.5 │ └── share │ ├── locale -> /app/share/runtime/locale │ └── runtime │ └── locale │ └── en │ └── batman
9. $ tree builddir builddir ├── export ├── files │ ├── bin │ │ └── ncdu │ ├── lib │ │ ├── libncurses.so.5 │ │ └── libtinfo.so.5 │ └── share │ ├── locale -> /app/share/runtime/locale │ └── runtime │ └── locale │ └── en │ └── batman
10. $ tree builddir builddir ├── export ├── files │ ├── bin │ │ └── ncdu │ ├── lib │ │ ├── libncurses.so.5 │ │ └── libtinfo.so.5 │ └── share │ ├── locale -> /app/share/runtime/locale │ └── runtime │ └── locale │ └── en │ └── batman
11. $ cat << EOF > metadata [Extension org.flatpak.ncdu.Locale] directory=share/runtime/locale autodelete=true locale-subset=true EOF
12. $ cat builddir/metadata.locale [Runtime] name=org.flatpak.ncdu.Locale [ExtensionOf] ref=app/org.flatpak.ncdu/x86_64/master
13. $ flatpak build-finish \ --filesystem=home \ builddir $ cat builddir/metadata (...) [Context] filesystems=home;
14. $ flatpak build-export \ --exclude='/share/runtime/locale/*/*' \ repo build master $ flatpak build-export \ --metadata=metadata.locale \ --files=files/share/runtime/locale \ repo build master
15. $ flatpak build-export \ --exclude='/share/runtime/locale/*/*' \ repo build master $ flatpak build-export \ --metadata=metadata.locale \ --files=files/share/runtime/locale \ repo build master
16. $ flatpak build-export \ --exclude='/share/runtime/locale/*/*' \ repo build master $ flatpak build-export \ --metadata=metadata.locale \ --files=files/share/runtime/locale \ repo build master
