Welcome to LQ.

Generic errors from an unknown file.tcl :
The errors you show in post #1 could be caused by a lot of faulty examples.tcl
There may be a solution if you attach "scen30.tcl" as : scen30.tcl.txt .
Attachments : That's the paper clip tool in the 'Advanced Editor'.

# 3 : The OLSR simulation file "scen30.tcl" : OK here.

The errors in post #1 : You are probable using a wrong executable 'ns'.

The 'ns' that you have built / will build with OLSR must be copied to e.g. ns-olsr.
And : $ sudo cp ns-olsr /usr/local/bin/
... Then all OLSR simulations will run OK with : $ ns-olsr <olsr-example>.tcl

OLSR info http://www.linuxquestions.org/questions/tags/olsr/

P.S. : Where did you get the file.tcl ? A link, please.
