In a new folder in /home/your folder/ :

$ tar xvfz ns-allinone-2.34.tar.gz

$ cd ns-allinone-2.34/


$ patch -p0 < otcl_ns234_gcc-4.4.patch


$ export CC=gcc-4.4 CXX=g++-4.4 && ./install

$ cd ns-2.34

$./validate

Welcome to LQ.
No executable 'ns' in ns-allinone-2.34/ns-2.34/ :
That's a failed build.
? Which "Linux OS" are you using ?
* Please specify your OS
http://www.linuxquestions.org/linux/...Ask_a_Question
I.e. a) The output from the command $ uname -m
b) OS name and version.


`tar xvf' will do, unless your 'tar' command
is older than the year 2004 version.
