Several Warnings and Error while starting asterisks

Hello community,
I have just installed Asterisk on Debian for frist development purposes. I cerated the sample configuration too (make sample).

When I start asterisk with asterisc -c , I see a couple of warnings and errors. I was not able to fix these errors yet. Maybe you could help me.
