have downloaded ex-linkage.cc and ex-linkage.tcl codes from the link
http://nile.wpi.edu/NS/linkage.html

i followed the steps involved as follows:

add the object file in makefile then
#make
#ns ex-linkage.tcl

these steps i followed but got the error message


[root@it-sdl019 ns-2.34]# ns ex-linkage.tcl

thanks in advance friend

really thanks for replying

In your script, you need to give the full path of MyAgent0tcl.

Otherwise, if you are running it from the same directory containing Agent then give "./" before the command name, namely

./Agent/MyAgent0tcl

other probable solution would be to check and fix the PATH environment variable before executing the script to include the Agent's path.

did u manage to solve the problem? i cant

you should run the command
#make install

after you run command #make in the ns2-*** dir.

And then you will run the script correctly.
