[Paparazzi-devel] A question about the new and adaptive navigation files

[Chris]

Yes it is me again sorry for asking again but i had some free time.
When i try to compile my plane using the new or adaptive navigation 
systems by using
<subsystem name="navigation"    type="new" />,
 i get:

BUILD CESSNA, TARGET sim
make[1]: Entering directory `/home/hendrix/paparazzi'
/home/hendrix/paparazzi/var/CESSNA/Makefile.ac:124: 
/home/hendrix/paparazzi/conf/autopilot/subsystems/shared/navigation_new.makefile: 
No such file or directory
make[1]: *** No rule to make target 
`/home/hendrix/paparazzi/conf/autopilot/subsystems/shared/navigation_new.makefile'.  
Stop.
make[1]: Leaving directory `/home/hendrix/paparazzi'
What am i doing wrong and secondly has anyone tried those navigation 
systems?
Are they better from the standard ones?
