Error with ns2 Installations – NS2 Revisited !

While installing ns2, sometimes we get errors some of them are mentioned below (as keywords used to search). Apart from these errors there are many other types of errors also which occurs.

tcl8.4.18 make failed! exiting…

tk8.4.18 make failed!

make: *** [tk3d.o] error 1 tk8.4.18 make

tk8.4.18 make fail

Here are some steprs and precautions to install ns2 in one shot.

1. Always install your linux distro with full programming support, this will help you to install ns2 more easily, here programming support means support for perl, tcl, gcc etc.

    

2. Do not forget to install make , on fedora type this in terminal

   yum install make*.*

3. Also install this packages

   yum install autoconf

   yum install automake

   yum install gcc-c++

   yum install libX11-devel

   yum install xorg-x11-proto-devel

   yum install libXt-devel

   yum install libXmu-devel

Now try installing ns2, hope it should get install properly

Error:  conversion from ‘const char*’ to ‘char*’

Suggested Solutions :
resolve my problem by casting const char* to char* using the code:
char* p= const_cast (strchr(localName, ‘(‘));
maybe this can help somebody having the same error

Credit goes to “rana”

Finally I overcame this problem. It needs to bechar* p= const_cast (strchr(localName, ‘(‘));
and not just
char* p= const_cast (strchr(localName, ‘(‘));
to work. Thanks or the tip!
ol, it takes the text as html and removes it.Anyway it isconst_cast”” (without the “”)

Errors:

————————————————–
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] Error 1
Ns make failed!

Solution:

1. open the file ranvar.cc and go to line number 219

2. replace:

return GammaRandomVariable::GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);

with:

return GammaRandomVariable(1.0 + alpha_, beta_).value() * pow (u, 1.0 / alpha_);

Reason:

In new version of compiler, there is a slight change in the way of handling constructors. Make the necessary changes like above for approximately four errors that we get during installation of ns2.

If you will get error like this:

mac/mac-802_11Ext.h: In member function ‘u_int32_t PHY_MIBExt::getHdrLen11()’:
mac/mac-802_11Ext.h:176:19: error: expected primary-expression before ‘struct’
mac/mac-802_11Ext.h:176:41: error: ‘dh_body’ was not declared in this scope
mac/mac-802_11Ext.h:176:51: error: ‘offsetof’ was not declared in this scope

Then open the file mac-802_11Ext.h and add this line in the begining of the file (highlighted as red)

#define ns_mac_80211Ext_h
#include <cstddef>
#include "marshall.h"
#include "timer-handler.h"

Cheers !
