ns2.34 setup on Ubuntu Lucid Lynx 10.04

Setting up ns2 on Ubuntu (Lucid Lynx 10.04),

$ sudo apt-get update
$ sudo apt-get install build-essential autoconf automake libxmu-dev libxt-dev libxt6 libsm-dev libsm6 libice-dev libice6 vim

Download ns-allinone.2.34.tar.gz – http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.34/

$ tar -xvzf ns-allinone.2.34.tar.gz
$ cd ns-allinone.2.34/
$ ./install

You might hit the error
otcl-1.13 make failed! Exiting

Solution
in otcl-1.13/configure file -
replace

Linux*)
SHLIB_CFLAGS="-fpic"
SHLIB_LD="ld -shared"
SHLIB_SUFFIX=".so"
DL_LIBS="-ldl"
SHLD_FLAGS=""
;;

with

Linux*)
SHLIB_CFLAGS="-fpic"
SHLIB_LD="gcc -shared"
SHLIB_SUFFIX=".so"
DL_LIBS="-ldl"
SHLD_FLAGS=""
;;

This should work now.
Note for this to work the CC value in Makefile.in inside otcl folder should be @CC@. It did not work when I changed it to gcc 4.3
Hope this helps
