Re: Problem with Ns on Linux Red Hat 6.0

Luca,

Try this. Set your LD_LIBRARY_PATH to include the directory containing 
libotcl.so before running ns. ( e.g. wich csh. setenv LD_LIBRARY_PATH 
/usr/local/lib, assuming your libotcl.so is in /usr/local/lib ). Or simply 
invoke ns in the directory containing libotcl.so.

If it works, you can relink your ns-2 with the following change in your 
Makefile:
	find the LIB = ... entry in your make file, and add 
		-R/usr/local/lib
	to it. 

Then you don't have to set your LD_LIBRARY_PATH again. 

Try it out and see what happens.
