I'm trying to install NS2 on Ubuntu 14.04. I followed the steps that are recommended and in this answer. But I'm still facing lots of errors.

Tcl is not part of the ns project. Please see
to see if they have a fix for your platform.
I tried a lot but I can't fix this Permission denied error. Or is there another problem?

Ubuntu 14.04 : libc6, libc6-dev was "updated", and can no longer be used to build old ns2. Ubuntu 12.04.5 can be used for the most versions. But not for certain patches / changes containing old code.
The usually recommended OS for ns2 is CentOS 6.8 - i386 ... except for the ~4 patches requiring a 64bits OS.
ns-allinone-2.28, Ubuntu 12.04.5, CentOS , etc. :
tar xvf ns-allinone-2.28.tar.gz
cd ns-allinone-2.28/
patch -p0 < ns228-gcc41-64_2016-1.patch
export CC=gcc34 CXX=g++34
./install
cd ns-2.28/
sudo make install
cp ns ns228-orig (This is your backup of the original 'ns')
sudo cp ns228-orig /usr/local/bin/
And do not add any *PATH to .bashrc . Not required.
