[Solved] flatpak and TCL
GNUser:
Every now and then there is an interesting application that I would like to try which is available for linux only as source code or flatpak. I don't have a specific application in mind at the moment but it happens often enough.
Would a flatpak extension add value to TCL x86_64? I'm not sure--maybe it is philosophically incompatible with TCL principles (too complex, with too many hooks into dbus +/- gnome-things)?
I'd be interested in knowing what the TCL developers and other users think about this. I don't want to put in the work of creating a flatpak.tcz (or requesting it if my efforts lead to a dead end) if it's not a good fit for our favorite OS.
GNUser:
It seems a TCL extension and a flatpak are antithetical in every possible way. I think I've answered my own question. Sorry for the noise.
hiro:
i for one would like your answer to be more concrete. is it just the dbus things? or what exactly? i have never looked deeply what dependencies there are for flatpak.

Hi hiro. I'm not sure but I will investigate and will get back to you.
GNUser:
Hi hiro. It seems flatpak is heavily dependent on dbus but not on systemd or other "gnome things".
I almost have it working in TCL with a binary-only extension (built from borrowed binaries and libraries from Devuan), but I don't know enough about dbus to get it quite right:
--- Code: ---$ tce-load -i flatpak
$ sudo /usr/local/etc/init.d/dbus start
starting dbus daemon...
$ flatpak remote-add flathub https://flathub.org/repo/flathub.flatpakrepo
Note that the directories
'/var/lib/flatpak/exports/share'
'/home/bruno/.local/share/flatpak/exports/share'
are not in the search path set by the XDG_DATA_DIRS environment variable, so applications installed by Flatpak may not appear on your desktop until the session is restarted.

--- End code ---
It seems flatpak-system-helper is important, so let's try to run it:
--- Code: ---$ sudo /usr/libexec/flatpak-system-helper
(/usr/libexec/flatpak-system-helper:11896): GLib-GIO-WARNING **: 08:36:06.570: Unexpected reply 2 when releasing name org.freedesktop.Flatpak.SystemHelper
--- End code ---
If someone knowledgeable about dbus can give me a hand, I would be happy to proceed--the goal being to submit a binary-only flatpak extension for the x86_64 repo. Otherwise, dbus and flatpak-system-helper have stopped me dead in my tracks.
