TCL installation error

In case, if ns2 have to be recompiled based on a new addition of protocol or agent, there should be an entry to the Makefile.in. After the changes are made, the following things need to be done to compile the agents. $] ./configure  $] make  but ./configure may throw an error as shown below like "Configure: Error: Installation of Tcl Seems to be incomplete or not found" TCL Error To correct this problem, please try the following $] ./configure --with-tcl-ver=8.5  The above works only after the successful installation of ns2. If you are installing ns2 for the first time refer this blog post http://www.nsnam.com/2014/11/ns2-installation-in-ubuntu-1404.html T S Pradeep Kumar
