在ubuntu上安装ns2，首先需要安装：
#sudo apt-get remove gcc
# sudo apt-get install
build-essential
# sudo apt-get install tcl8.4 tcl8.4-dev tk8.4 tk8.4-dev
# sudo apt-get install libxmu-dev libxmu-headers
接着到ns2的SourceForge去下载软件包，目前的最新版是2.35。
把解压缩后的文件夹，搬到想安装的位置去。例如：
# tar xvfz
ns-allinone-2.35.tar.gz
cd /home/administrator/ns-allinone-2.35
sudo
./install
安装完成后 提示
IMPORTANT NOTICES:
(1) You MUST put /home/administrator/ns-allinone-2.35/otcl-1.14,
/home/administrator/ns-allinone-2.35/lib,
into your
LD_LIBRARY_PATH environment variable.
If it
complains about X libraries, add path to your X libraries
into
LD_LIBRARY_PATH.
If you are
using csh, you can set it like:
setenv
LD_LIBRARY_PATH
If you are
using sh, you can set it like:
export
LD_LIBRARY_PATH=
(2) You MUST put
/home/administrator/ns-allinone-2.35/tcl8.5.10/library into your
TCL_LIBRARY environmental
variable.
Otherwise ns/nam will complain during startup.
After these steps, you can now run the ns validation suite
with
cd ns-2.35;
./validate
修改环境变量
export
PATH="$PATH:/home/administrator/ns-allinone-2.35/bin:/home/administrator/ns-allinone-2.35/tcl8.5.10/unix:/home/administrator/ns-allinone-2.35/tk8.5.10/unix"
export
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/administrator/ns-allinone-2.35/otcl-1.14,
/home/administrator/ns-allinone-2.35/lib"
export
TCL_LIBRARY="$TCL_LIBRARY:home/administrator/ns-allinone-2.35/tcl8.5.10/library
"
完成后在新终端窗口 输入ns
出现% 则安装成功
