NS2.33安装

转自:http://blog.163.com/zhuandi_h/blog/static/18027028820125742050658/

系统：win7,winXp

cygwin安装教程：

1.下载NS2.33

http://sourceforge.net/projects/nsnam/files/allinone/

或http://download.youkuaiyun.com/download/morre/1114655

2.解压

将ns-allinone-2.33.tar.gz拷贝至cygwin下home目录下的个人用户中，如我的cygwin/home/lenovo

启动cygwin,输入以下命令，实现解压

tar zxvf ns-allinone-2.33.tar.gz

3.修改源代码

  源码中存在一些错误，需要进行修改在编译

 在C:\cygwin\home\lenovo\ns-allinone-2.33\tcl8.4.18\unix中增加如下定义，添加如下：

#include "tclInt.h"

#include "tclPort.h" #include <locale.h> #define TM_YEAR_BASE 1900 #define IsLeapYear(x) ((x % 4 == 0) && (x % 100 != 0 || x % 400 == 0))

/* * TclpGetDate is coded to return a pointer to a 'struct tm'. For * thread safety, this structure must be in thread-specific data. * The 'tmKey' variable is the key to this buffer. */

static Tcl_ThreadDataKey tmKey; typedef struct ThreadSpecificData { struct tm gmtime_buf; struct tm localtime_buf; } ThreadSpecificData;

/*

*增加如下定义

*/

struct timezone{ int tz_minuteswest; int tz_dsttime; };

/* * If we fall back on the thread-unsafe versions of gmtime and localtime, * use this mutex to try to protect them. */

如不进行修改，则可能会出现以下错误：

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c: In function `TclpGetClicks':

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c:100: error: storage size of 'tz' isn't known

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c:100: warning: unused variable `tz'

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c: In function `Tcl_GetTime':

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c:253: error: storage size of 'tz' isn't known

/home/lenovo/ns-allinone-2.33/tcl8.4.18/unix/tclUnixTime.c:253: warning: unused variable `tz'

Makefile:1089: recipe for target `tclUnixTime.o' failed

make: *** [tclUnixTime.o] Error 1

4.打补丁

  http://bugs.gentoo.org/show_bug.cgi?id=225999下载补丁tk-8.4.18-tkBind.patch（右键单击tk-8.4.18-tkbind.patch 然后保存在allinone-2.33目录下）

进入allinone-2.33目录打上补丁，输入以下命令打补丁：

cd /home/lenovo/allinone-2.33

patch -p0 < tk-8.4.18-tkBind.patch

5.安装

进入allinone-2.33目录，进行安装

./install

编译较漫长。

成功后出现以下界面

6.配置环境变量

  打开cygwin\home\lenovo\.bashrc文件，在文件末尾加入这些信息： 

export NS_HOME=/home/lenovo/ns-allinone-2.33 export PATH=$NS_HOME/nam-1.13:$NS_HOME/tcl8.4.18/unix:$NS_HOME/tk8.4.18/unix:$NS_HOME/bin:$PATH export LD_LIBRARY_PATH=$NS_HOME/tcl8.4.18/unix:$NS_HOME/tk8.4.18/unix:$NS_HOME/otcl-1.13:$NS_HOME/lib:$LD_LIBRARY_PATH export TCL_LIBRARY=$NS_HOME/tcl8.4.18/library

注：.bashrc文件可以用记事本打开，不过最好用UE，因为它是unix格式的文本

7.测试NS2

关闭cygwin，打开Xwin Server,输入以下命令：

$ /home/lenovo/ns-allinone-2.33/ns-2.33/tcl/ex

$ ns simple.tcl

则会出现以下模拟图，点击运行按钮，可观看网络流量的流动：

至此，NS2.31安装成功。
