Public bug reported:
There is no separate bug tracker for XMir so I figured that it belongs under
Mir.
I installed my own Gtk native Linux arm app (a game) on my ubuntu phone and I
was happily using it with the following launcher
(~/.local/share/applications/lazsnake.desktop):
[Desktop Entry]
Name=lazSnake
Comment=Simple snake game written in Lazarus by Kris Jacewicz
X-Ubuntu-Touch=true
X-Ubuntu-XMir-Enable=true
Exec=/home/phablet/.local/xmir/lazSnake/lazsnake
Icon=/home/phablet/.local/xmir/lazSnake/lazsnake.png
Path=/home/phablet/.local/xmir/lazSnake
Terminal=false
Type=Application
Obviously the app folder is under ~/.local/xmir/lazSnake
Just today I updated the Ubuntu Touch on my Meizu MX4 phone.
Before update the build description was: Ubuntu 15.04-armhf (20160913-020303)
After update: Ubuntu 15.04-armhf (20161201-020304)
The very same game no longer works. Clicking on its icon in the Apps scope
starts it but it immediately closes.
Whatever is the reason, I was already in the past updating my OS couple of
times and always was able to use the app without any problems at all. Now,
after updating, I can no longer do this. Whatever the reason is, apparently the
new Ubuntu image broke some backward compatibility.
Also, I chose libertine as package only because otherwise I would not be able
to even post this, but my problem is totally unrealted to Libertine.
Some error messages I was seeing are:
