Re: [ns] TCl class problem

["Leonardo Mattos" <leonardo_mattos@hotmail.com>]

Debo,

I am attaching below two of the C++ files (marker.cc and marker.h) that I 
want to add. Just to mention again, the respective object (marker.o) was 
created when I did a ./configure followed by a "make".
But some how when I tried to test it, using a basic command
[lsmattos@pcmt5 ns-2.1b6]$ ns
% Marker
invalid command name "Marker"

I must say that I have no problems at all with the files (codes) that were 
provided by ns-allione-2.1b6. Let's say, I do the same thing to test tbf.cc 
, provided by ns itself. I got a message that makes sense, recognizing that 
the class TBF exists.

% TBF
wrong # args: should be {TBF message ?args...?}

I am quite desperate to find out my problem. I must also say that I looked 
for similar problems in the mailing list but did not find anything.
Any help will be really appreciated.
Leo
