Creating your first Genode application - Build succesful, butexecution fails

[w_schmidt at ...181...]

Hello Helmuth,

Sorry,
I have not seen you're answers (some automatism seems  to consider every 
thing from genode mail list as spam).

Because I had some strange graphic problems with Ubuntu 12.04 on the 
physical computer+-, I also tried a reinstall with another distribution 
(Mint). With Mint at least  run/demo works.

But the self created hello doesn't.

I have found only an empty /tmp/genode-1000 directory (therefore the grep 
command you provided shows nothing).

The demo which is provided in genode nor works after update (git pull) of 
genode, but notif i try to run it with the nova kernel (the lower part of my 
last mail, it still says "no route to service "IO_PORT")

Best regards,
Wolfgang
