["JUAN.RAFAEL" <JUAN.RAFAEL@terra.es>]

hi.
My name is Rafael, my problem is the following:     
When trying to compile the otcl-1.0a7 in Windows 98 with the M.Visual 
C++ 5.0 this  gave the following error:

This problem believes that he was solved commenting the it lines of the 
makefile.vc for the otcl:   
 all: $(OTCLLIB) OTCLSH.EXE OWISH.EXE  
  
But when executing the file again I obtain a new error:

In the list of problems the one that I have appears me, and I eat 
answer to the problem they indicate that:  

  -You might want to download the prebuilt windows binary of ns.  
   http://www.isi.edu/nsnam/dist/binary /   

 I discharge the file ns-2.1b8a.exe, and what I want to know is like I 
can use this file to solve my problem, because I don't have the 
smallest idea.
In case that indicated previously is not the solution, indicate me some 
other form of solving it
