[maemo-developers] printing logs (printf) when application starts from menu

Sounds like this would be a useful feature for the hildon-launcher to  
support. I would like to see hildon-launcher reporting errors to some  
central server (a la M$ Windows error reporter) and any stdout/stderr  
output would would be a useful thing to have. This reporting tool does  
actually exist within Nokia for internal testing, but would probably  
also be useful for the outside world, obviously with tweaks to where  
the debugging information is sent.

I remember on Opie (running on the Zaurus) there was a central log  
screen which showed the output of all of the Opie applications. I  
wonder if this would be an option, or perhaps just automatically  
piping the output from individual applications a pid-specifc temporary  
log file under /var (which could then be sent off with an error report  
should one occur, or would otherwise be deleted when the app closes).

Hildon launcher is here:  
https://stage.maemo.org/svn/maemo/projects/haf/trunk/maemo-launcher/launcher/

Have a look and see what patches you think might do the job.

Cheers,


Simon
