参考书推荐：《NS与网络模拟》 - 徐雷鸣等

1. NS2下载

   官网提供最新版本的下载： http://www.isi.edu/nsnam/ns/ ， 我下载的版本是NS2.34， 下载的文件为ns-allinone-2.34.tar.gz 。

   下载完后将它解压缩到主文件夹下（我的是 /home/yanna）：

   tar xvfz ns-allinone-2.34.tar.gz

2. 需要用到的软件包

   build-essential

   tcl8.4 tcl8.4-dev tk8.4 tk8.4-dev

   libxmu-dev

3. 安装

   cd /home/yanna/ns-allinone-2.34

   sudo ./install

4. 出错处理

ld -shared -o libotcl.so otcl.o
otcl.o: In function `OTclDispatch':
/home/yanna/ns-allinone-2.34/otcl-1.13/otcl.c:495: undefined reference to `__stack_chk_fail_local'
otcl.o: In function `Otcl_Init':
/home/yanna/ns-allinone-2.34/otcl-1.13/otcl.c:2284: undefined reference to `__stack_chk_fail_local'
ld: libotcl.so: hidden symbol `__stack_chk_fail_local' isn't defined

See http://www.isi.edu/nsnam/ns/ns-problems.html for problems

   在官网上有解决方案，应该是个BUG，会在以后版本中解决：

For Ubuntu 9.10 (karmic), you may encounter this error in the linking of otcl:

otcl.o: In function `OTclDispatch':
/home/ns/ns-allinone-2.34/otcl/otcl.c:495: undefined reference to `__stack_chk_fail_local'
otcl.o: In function `Otcl_Init':
/home/ns/ns-allinone-2.34/otcl/otcl.c:2284: undefined reference to `__stack_chk_fail_local'
ld: libotcl.so: hidden symbol `__stack_chk_fail_local' isn't defined
ld: final link failed: Nonrepresentable section on output
make: *** [libotcl.so] Error 1

This error is because the linker being used is "ld -shared" instead of "gcc -shared". If you edit one line in otcl-1.13/configure, and rerun install, it should work:

--- configure.orig 2009-11-02 12:14:52.556167945 -0800
+++ configure 2009-11-02 12:17:28.966706099 -0800

This will be fixed in future revisions of ns-2. 

   改完后重新安装。

5. 配置环境变量

   安装完成后会看到修改环境变量的提示：

Please put/home/yanna/ns-allinone-2.34/bin:/home/yanna/ns-allinone-2.34/tcl8.4.18/unix:/home/yanna/ns-allinone-2.34/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.

IMPORTANT NOTICES:

(1) You MUST put /home/yanna/ns-allinone-2.34/otcl-1.13, /home/yanna/ns-allinone-2.34/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 <paths>
    If you are using sh, you can set it like:
        export LD_LIBRARY_PATH=<paths>

(2) You MUST put /home/yanna/ns-allinone-2.34/tcl8.4.18/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-2.34; ./validate

For trouble shooting, please first read ns problems page
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive
for related posts.

   回到主文件夹，修改bash配置文件.bashrc：

   sudo gedit .bashrc

   在文件最后加上：

PATH="$PATH:/home/yanna/ns-allinone-2.34/bin:/home/yanna/ns-allinone-2.34/tcl8.4.18/unix:/home/yanna/ns-allinone-2.34/tk8.4.18/unix"

LD_LIBRARY_PATH="/home/yanna/ns-allinone-2.34/otcl-1.13:/home/yanna/ns-allinone-2.34/lib"

TCL_LIBRARY="$TCL_LIBRARY:/home/yanna/ns-allinone-2.34/tcl8.4.18/library"

6. 安装验证

   安装结束后的提示中也告诉我们如何验证是否正确安装：

   cd ns-2.34

   ./validate

   另外，也可以打开一个新终端进行试运行：

   输入ns，如果显示一个%则说明已正确安装。如果提示“command not found”则重新启动试试。
