Testing the Flatpak package

[Alexander Wilms]

Hi,

Mike and I have been working on a Flatpak build recipe: 
https://savannah.gnu.org/patch/?9440

If you want to try it and already have flatpak installed, you'll need to 
follow these steps:

Manually download 
https://drive.google.com/file/d/0B1SoIjRsaQikZXB1bGxBcGxhTzQ (sha256: 
bfd38cdf358b5f2d975505af784a225d2c9f171fb2a844b09e969a9c53de0f84)
flatpak remote-add kderuntime --from 
http://distribute.kde.org/kderuntime.flatpakrepo
flatpak install kderuntime org.kde.Platform 5.9
flatpak install --bundle Octave.flatpak
flatpak run org.octave.Octave (or start it via the usual application 
launcher)

If you want to build it yourself:

flatpak remote-add kderuntime --from 
http://distribute.kde.org/kderuntime.flatpakrepo
flatpak install kderuntime org.kde.Sdk 5.9
flatpak install kderuntime org.kde.Platform 5.9
git clone http://github.com/Alexander-Wilms/flathub
cd flathub
git checkout org.octave.Octave
flatpak-builder --ccache --force-clean --repo=octave-repo octave-build 
org.octave.Octave.json (This creates a local repository)
flatpak remote-add --no-gpg-verify octave-repo octave-repo
flatpak install octave-repo org.octave.Octave
flatpak run org.octave.Octave

I've tested it a bit and haven't found any issues so far. The only thing 
missing right now should be OpenJDK. If you encounter any problems, 
please post them to the linked thread.

Cheers,

Alex
