Hi Ning, Thanks again. "weston-ivi" is already installed (but there is no icon) and uninstalling it removes the homescreen and other packages. I re-installed a new image and tried to run applications without installing the "ico-uxf-homescreen".
After I install my "hello world" application (from SSH as root, using "rpm
-i"), I can execute it (directly by typing "awhello" in the wayland
terminal, as "app"). The application shows up (great!). When I try to do
the same with "launch_app", I get the usual "launch failed". You said
something about a database for launch_app. How can I get my application in
there ?
By the way, what is the password for "app" ?
Thank you and best regards,
Olivier

RE: How to launch a native app ?
Hi Olivier,
Looks like you are working on ICO homescreen where there is no icon for
weston-terminal.
Though you modified dialer’s desktop file, the database was not updated.
That’s why you still see dialer.
If you want to use weston-terminal, you can try “zypper install weston-ivi”
which will bring up weston desktop with terminal icon on the top left.
Thanks,
Ning

Hi Ning,
Thank you. "launch_app org.tizen.dialer" works (both as "root" and as
"app"). However, it returns "... successfully launched" when run as root
and "... launch failed" when run as "app". But in both cases, the dialer
appears on the screen. I cannot start any other application (especially not
my "hello world" or the terminal).
To get the terminal, I tried to modify the "Exec=/usr/bin/dialer" into
"Exec=/usr/bin/weston-terminal" in org.tizen.dialer.desktop. But even that
doesn't work : clicking on the dialer icon or executing launch_app both
start the dialer instead of the terminal. I also tried from SSH (as "root"
and "app") and from the console behind Ctrl-Alt-F2.
Thank you,
Olivier

RE: How to launch a native app ?
Hi Oliver,
You can run “launch_app org.tizen.dialer” via ssh. You need first set
password for user “app”, then login ssh as user “app”.
Thanks,
Ning

Hi Geoffroy and Kevron,
Thanks a lot for your help (and for your patience). Yes, I was trying to
run it as root, and another mistake was to try to run from an SSH terminal.
I will try to run it as "app".
But here comes the most stupid question of all : how can I start the
terminal ???
Best regards,
Olivier

Hi Olivier,

I mentionned that you should not be root for this but there may be other
things that cause this issue. I'm thinking specifically that if the
SMACK label is not correct then this could be a problem. A quick test
for this would be to add 'security=none' to your kernel command-line and
try again. Note that you really *don't* want to keep running with
security turned off and so we'd need to look at the exact problem for
your app.

We have some info about logging on Tizen IVI on this page:
https://wiki.tizen.org/wiki/IVI/Enable_Logging I don't know if this will
yield to any result for your app but please do let me know
(specifically, I'm not familiar as to whether you'd need to do anything
in your app to get additional info).

We have the wiki page above regarding getting logs, any suggestion for
enhancing it is more than welcome. We don't have a wiki page for writing
a native app and we typically point people at the 'lemolo' app as a
starting point (which is exactly what you did). Another good source of
information is the presentation that Dominig Ar Foll presented at FOSDEM
this year entitled: 'A multi-user App Framework' (there is a link to it
here: https://wiki.tizen.org/wiki/IVI#FOSDEM.2714)
