Questions[ns2](ubuntu)

Could anybody please help me. Why showing this error while I am trying to run the command for sample mptcp?

The file is available here https://github.com/wangzhizhou/Network-Simulator-Installation-Guideline-For-Ubuntu/blob/master/README.md

I am trying to install a network simulator onto Ubuntu on my virtual machine(VMWare). It requires me to move the file downloaded into the opt folder in order for me to run other commands for installation. Tried this: sudo cp -r /home/denisayebare/Downloads/ns-allinone-2.35.tar.gz/opt/

And brought back this:

cp: missing destination file operand after '/home/denisayebare/Downloads/ns-allinone-2.35.tar.gz/opt/

I am new to NS2. In any tcl file where flooding is done, MESSAGE_PORT is always set to 42. What is the reason behind this?

So i tried installing gcc 4.8 on Ubuntu 19.4 but i keep getting errors. I figured it must be happening because Ubuntu 19.4 does not support gcc 4.8. The error says that the package might be obsolete. What do i do? Please help!
