Due to my project work i need to modify the ns-bgp modules...after modifying the cc file..i used the following command to recompile it..
$make clean
$make
it gives me the following error.

You will of course have to install the compilers (g++-*).
I.e. you cannot use a command that isn't present on your OS.

Besides that : Don't use g++ . Please use `g++-4.4´.

Ns2 prerequisites : $ sudo apt-get install \
g++ g++-4.4 automake make patch libtool libxmu-dev xgraph

@knudfl
I reconfigure my ns using:
reconfigure ns-2.34/ :
$ export CC=gcc-4.4 CXX=g++-4.4 && ./configure
$ make clean && make

It shows me the following error.

← ref. #3 .

Which Ubuntu 12.04 are you using ? i686 or x86_64 ?
This command will show : $ uname -m

Ns2 is for a 32bits OS (i686).
However the most protocols will also work with 64bits.

i686


I m using BGP protocol

In post #1 you are saying :
I guess you can watch your coding errors in post #3 :

I can remove the coding error, but what is this error.

Im trying to patch up bgp on ns2.34 for my project work, i get the same error message. Kindly help if u got any solution please...

Please follow the text in post #2. Cannot fail.

If you have read all posts in the thread,
you will know that your OS must be specified, if you want answers.

Sorry sir, i am new to NS & Unix environment

My OS: Ubuntu 12.04 LTS
OS type: 32bit

I have gone through text of 2#, i need some step wise procedure please. I presume these steps, pl correct me..
a) Install Ns2 prerequisites
b) Install Ns2.34 (Procedure that i followed from http://ns2-ubuntu.blogspot.in/2013_03_01_archive.html)
c) Unzip nsBGP downloaded from http://www2.ensc.sfu.ca/~ljilja/cnl/...-2.34-BGP.html
d) Download the patches given in postings #2
e) Apply them and proceed as directed.

In other posting #28 (from http://www.linuxquestions.org/questi...984/page2.html), you were elaborating about bgp-ns-2.34-ubuntu1004_i386.deb; is this one step process for the above?

Pl bear with me if i am wrong.. Thanks in advance..

← ref. #10.

? Any particular reason for using the old (and wrong) texts from
http://ns2-ubuntu.blogspot.in/2013_03_01_archive.html
The otcl-1.13/configure edit´s don't work with Ubuntu 12.04 - 32 any more.
Hence the patch otcl_ns234_gcc-4.4.patch : Made up for a reason.

Please use the 2015 updated, and easier / simpler steps from post #2 :

And : $ cd ns-2.34/

$ sudo cp ns234-bgp /usr/local/bin/
... Then all simulation can be done with $ ns234-bgp file.tcl

And .... you can delete any entries made to .bashrc.
The old ~1999 text is meant for a "University Computer" only.
I.e. when you had no write or install permissions to /usr/.

Don't believe everything on the Internet.
Most ns2 "tutorials" are written by young students,
who are using ns2 and a Linux OS for the first time.
And texts are usually copied from texts written by other students.

reference post #11

Sir,
I am ok with the step Ns2 prerequisites.

Have some doubts regarding Building ns-allinone-2.34/ + BGP :

Is my steps correct? Pl correct me if i am wrong..

1) Unzip ns-allinone-2.34.tar.gz (Downloaded from sourceforge.net)
2) Copy downloaded patches (ref#2) otcl_ns234_gcc-4.4.patch and bgp_ns234.patch into ns-allinone-2.34 folder
3) $ patch p0 < otcl_ns234_gcc-4.4.patch
4) $ patch p0 < bgp_ns234.patch
5) $ export CC=gcc-4.4 CXX=g++-4.4 && ./install
6) $ cd ns-2.34/
$ sudo make install
$ cp ns ns234-bgp
$ sudo cp ns234-bgp /usr/local/bin/
Then all simulation can be done with $ ns234-bgp file.tcl

Sir my objective is to implement ns-2.34-BGP-rfd_mrai and study..

For implementing ns-2.34-BGP-rfd_mrai, whether i need to complete the above steps and proceed with the procedure given in http://www2.ensc.sfu.ca/~ljilja/cnl/...-rfd_mrai.html (ref#25 on http://www.linuxquestions.org/questi...984/page2.html)

OR (ref#28 on http://www.linuxquestions.org/questi...984/page2.html) by downloading the package bgp-ns-2.34-ubuntu1004_i386.deb?

Thank you..

← ref. #12.

Please "read" the patch, bgp_ns234.patch :
$ grep -n Makefile.in bgp_ns234.patch
... to know that MRAI is present :
12229 ..... bgp/Timing/mraitimer.o bgp/Timing/mraiperpeertimer.o \

And : $ grep -n mrai bgp_ns234.patch

So I think that I included rfd_mrai.
You have : ns-2.34/bgp/{files.cc, .h, Comm/*, Path/*, Timing/*, Util/*}.

The older? "patch package", ns-2.34-bgp-rfd-mrai.tar.gz is with fewer files:
ns-2.34/bgp/{files.cc, .h, Timing/* }.

Suggest : Setup another ns-allinone-2.34/ to check differences.
You can have as many ns-allinone-2.34/ as you want, installed at the same time.
But do not add any *PATH text to .bashrc ( Never required.)


The (6.6 MB) package bgp-ns-2.34-ubuntu1004_i386.deb :
Provides /usr/local/bin/{ ns-bgp, ns-bgp-rfd }.
And is just an easy way for running the simulations,
.. without having to build ns-allinone-2.34 + [bgp, rfd_mrai].

ref#13

Dear Sir,

1) I extracted the ns-allinone-2.34.tar.gz file
2) Copied otcl_ns234_gcc-4.4.patch file into ns-allinone-2.34 folder
3) Executed patch p0 < otcl_ns234_gcc-4.4.patch command, it shows the following error

← ref. #14.

Ubuntu will often fail with patches.
But luckily it's just about one word in the patch `otcl_ns234_gcc-4.4.patch´.

And you can edit "otcl-1.13/Makefile" line 16, from
SHLIB_LD= @SHLIB_LD@
to :
SHLIB_LD= gcc -shared

... If not already done :
Sometimes "patch" replies with FAILED, when everything has been done OK.
