Ubuntu下安装ns步骤

ns版本为：ns-allinone-2.33.tar.gz

1，从官网上下载ns-allinone-2.33.tar.gz版本http://sourceforge.net/projects/nsnam/files/allinone/ns-allinone-2.33/ns-allinone-2.33.tar.gz/download?use_mirror=nchc

2，在home文件夹下建立ns2文件夹

3，将下载的打包文件，拷贝到/home/ns2文件夹下，并且解压该文件

4，进入ns-allinone-2.33文件夹，执行./install，若有错误：

4.1 进入otcl-1.13目录，找到configure.in, 将77行，SHLIB_LD="ld -shared" 改为SHLIB_LD="gcc -shared".同时修改configure 第5518行SHLIB_LD="ld -shared"改为SHLIB_LD="gcc –shared"

否则./install时会出现如下提示：

ld: libotcl.so: hidden symbol `__stack_chk_fail_local' isn't defined

ld: final link failed: Nonrepresentable section on output

make: *** [libotcl.so] 错误 1

otcl-1.13 make failed! Exiting ...

4.2 执行./install时若遇到如下错误：

遇到的错误

(1) 错误一：安装NS2.33过程中出现如下的错误：

tools/ranvar.cc: In member function ‘virtual double GammaRandomVariable::value()’:

tools/ranvar.cc:219:70: error: cannot call constructor ‘GammaRandomVariable::GammaRandomVariable’ directly

tools/ranvar.cc:219:70: error: for a function-style cast, remove the redundant ‘::GammaRandomVariable’

make: *** [tools/ranvar.o]错误1

Ns make failed!

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

在ns-allinone-2.33/ ns-2.33/tools文件夹下，找到报错提示中的ranvar.cc文件，打开找到对应的219行删除::GaammaRandomVariable，保存，即：将219行的return GammaRandomVariable::GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);改为：return GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);

(2) 错误二：重新在ns目录下键入$ ./install安装，再次出现同类问题时，如：

mobile/nakagami.cc: In member function ‘virtual double Nakagami::Pr(PacketStamp*, PacketStamp*, WirelessPhy*)’:mobile/nakagami.cc:183:73: error: cannot call constructor ‘ErlangRandomVariable::ErlangRandomVariable’ directly

mobile/nakagami.cc:183:73: error: for a function-style cast, remove the redundant ‘::ErlangRandomVariable’

mobile/nakagami.cc:185:67: error: cannot call constructor ‘GammaRandomVariable::GammaRandomVariable’ directly

mobile/nakagami.cc:185:67: error: for a function-style cast, remove the redundant ‘::GammaRandomVariable’

make: *** [mobile/nakagami.o]错误1

Ns make failed!

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

解决方法：

在ns-allinone-2.33/ ns-2.33/ mobile文件夹下，找到报错提示中的nakagami.cc文件，打开找到对应的183行删除::ErlangRandomVariable，保存，即：将183行的resultPower = ErlangRandomVariable::ErlangRandomVariable(Pr/m, int_m).value();

改为：resultPower = ErlangRandomVariable(Pr/m, int_m).value();

在ns-allinone-2.33/ ns-2.33/ mobile文件夹下，找到报错提示中的nakagami.cc文件，打开找到对应的185行删除::GammaRandomVariable，保存，即：将185行的

resultPower = GammaRandomVariable::GammaRandomVariable(m, Pr/m).value();

改为：resultPower = GammaRandomVariable(m, Pr/m).value();

重新在ns目录下键入$ ./install安装，再次出现同类问题时，仿照此次解决方法，找到对应的文件和行数，修改即可。直到安装成功。

更新环境变量：（注意红色的为我安装的目录）export PATH=$PATH:/home/ns2/ns-allinone-2.33/bin:/home/ns2/ns-allinone-2.33/tcl8.4.18/unix:/home/ns2/ns-allinone-2.33/tk8.4.18/unix

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ns2/ns-allinone-2.33/otcl-1.13:/home/ns2/ns-allinone-2.33/lib

export TCL_LIBRARY=$TCL_LIBRARY:/home/ns2/ns-allinone-2.33/tcl8.4.18/library

然后执行source /etc/bash.bashrc

5.安装成功后会出现以下信息：

IMPORTANT NOTICES:

(1) You MUST put /home/ruan/ns-allinone-2.33/otcl-1.13, /home/ruan/ns-allinone-2.33/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/ruan/ns-allinone-2.33/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-2.33; ./validate
