This doesn't help answer your question directly, but any particular reason why you're trying to install NS2?and also on Ubuntu 18.x?

@James Baldwin, welcome to LQ.

ns2 can be compiled with a "no PIE" g++ version 4.4 .. 5.4 , no later.

Solution for Ubuntu 18.04 : $ sudo apt install g++-4.8

ns-2.35 :

Code:

tar xvf ns-allinone-2.35_gcc5.tar.gz     // 2014 .. 2017 update
https://drive.google.com/file/d/0B7S...ew?usp=sharing
cd ns-allinone-2.35/
export CC=gcc-4.8 CXX=g++-4.8 && ./install

(TCL) Configuring routing protocol...
invalid command name "Agent/rtProto/OSPF"
while executing
