title: Integration of ns-2.35 and EvalVid 2.7
body: <p>I use ubuntu 14.04 and i am trying to integrate evalvid 2.7 and ns2.35. I added necessary files like: myevalvid.cc, myudp.cc, myudp.h, myevalvid_sink.cc, myevalvid_sink.h . And inside the Makefile.in i have put myevalvid/myudp.o, myevalvid/myevalvid_sink.o and myevalvid/myevalvid.o in the OBJ_CC list.</p>
  
  <p>But the problem is, when i enter the <code>./configure</code> command, i get this error from the console referring to the tcl program:</p>

  configure: error: Installation of tcl seems incomplete or can't be found automatically.
  Please correct the problem by telling configure where tcl is
  using the argument --with-tcl=/path/to/package
  (perhaps after installing it),
  or the package is not required, disable it with --with-tcl=no.
