@Nithesh dupaguntla :

Hi.

May be you are using the wrong compiler ?
Fedora : gcc / g++ version 3.4.6
Ubuntu : gcc / g++ version 4.1.2
... Please advise OS specifications : a ) The reply from the command $ uname -m
b) The OS name and version.

@Umair Chaudhry ,  Hi.

Ubuntu 14.04 - 64bits and ns-allinone-2.31 :  Please use gcc34, g++34 → →

cd ns-allinone-2.31/
export CC=gcc34 CXX=g++34 && ./install

If configuring in ns-2.31/ :  export CC=gcc34 CXX=g++34 && ./configure

Getting the compilers gcc34 and g++34 :
compat-gcc34  https://drive.google.com/file/d/0B7S255p3kFXNRTkzQnRSNXZ6UVU/view?usp=sharing
compat-gcc-34-c++  https://drive.google.com/file/d/0B7S255p3kFXNV3J3bnVoWGNWdG8/view?usp=sharing

Download the two package, and

cd Downloads/
sudo gdebi compat-gcc34-3.4.6-ubuntu1204-1_amd64.deb compat-gcc-34-c++_3.4.6-20_amd64.deb

@knudfl , Hello and thank you for your reply.

So I followed your instructions and here is what I encountered.
1- I downloaded and installed compat-gcc34 and compat-gcc-34-c++ using gdebi.
2- Doing export CC=gcc34 CXX=g++34 && ./install in ns-allinone folder gave the following error at the end

make: g++34: Command not found
make: *** [embedded-tcl.o] Error 127
tclcl-1.19 make failed! Exiting ...
See http://www.isi.edu/nsnam/ns/ns-problems.html for problems

3- I jumped to the ns2.31 folder which in my case is ns-2.31dtsncc and ran export CC=gcc34 CXX=g++34 && ./configure. It appeared to run correctly but when I tried the make command later it gave the following error

make: g++34: Command not found
make: *** [utils_ns.o] Error 127

4- Make depend gave the followig error

/bin/sh: 1: Syntax error: Bad fd number
make: *** [depend] Error 2

5- More details of the error are available at https://www.dropbox.com/s/3fu9sz6em5dgkfs/compiler%20error?dl=0
6- I have been trying this for so long but have been failing. What I'm actually trying to do is add a folder to my ns2.31 which was given to me by my senior. The folder is available at https://www.dropbox.com/s/gmmp0dj6pxgapeb/ns-2.31dtsncc.tar.gz?dl=0

Please let me know if you can help. I will greatly appreciate it. Thank you.

@Umair Chaudhry, Hi.

»» g++34: Command not found «« : Usually means you did not install the packages.

Please do all the check commands to decide if gcc34, g++34 are present :
$ which gcc34
$ which g++34
$ ls /usr/bin/gcc*
$ ls /usr/bin/g++*
$ dpkg -L compat-gcc-34-c++

* I already have your  "ns-2.31dtsncc.tar.gz" ... from our correspondence here
 http://askubuntu.com/questions/797789/ns-2-31-make-fail-while-adding-a-transport-layer-protocol
... and by the way, I have made a reduced backup, ns231dtsncc-2.tar.gz, 9.2MB
https://drive.google.com/file/d/0B7S255p3kFXNMVhVYXlXTnI4eXM/view?usp=sharing
... with the simulation scripts and the surplus applications omitted.

The "ns-2.31 + dtsncc etc." compiles OK here, until the ndtsn.cc errors appear :

ndtsn/ndtsn.cc: In constructor `NDtsnAgent::NDtsnAgent()':
ndtsn/ndtsn.cc:48: error: `wnd_' was not declared in this scope
ndtsn/ndtsn.cc: In member function `char* NDtsnAgent::get_bitmap_string(int*)':
.
ndtsn/ndtsn.cc: In member function `virtual int NDtsnAgent::window()':
ndtsn/ndtsn.cc:573: error: `wnd_' was not declared in this scope
ndtsn/ndtsn.cc: In member function `virtual double NDtsnAgent::windowd()':
ndtsn/ndtsn.cc:578: error: `wnd_' was not declared in this scope

@knudfl so here is what I did.

1- after the steps I mentioned in my previous reply, I explained the problems that I was encountering. So I took help from one of your previous replies on  http://askubuntu.com/questions/797789/ns-2-31-make-fail-while-adding-a-transport-layer-protocol and used

export CXX=g++-4.4 && ./configure

followed by a make in the ns2.31dtsncc folder. This time it showed no error. However, I only exported the g++4.4 and not the gcc compiler. 

2- so now,, I have something as below

umair@umair-VirtualBox:~$ which gcc34

/usr/bin/gcc34

root@umair-VirtualBox:/home/umair# which g++-4.4

/usr/bin/g++-4.4

3- also, I dont see gcc34 from the following command

root@umair-VirtualBox:/home/umair# dpkg --list | grep compiler

ii  g++                                                   4:4.8.2-1ubuntu6                                    amd64        GNU C++ compiler

4- Finally, the folder that I just made (the one that you also have 'ns2.31dtsncc') has the GPSR protocol included in it I believe. But running one of the tcl scripts(attached) gives me the following error. 

root@umair-VirtualBox:/home/umair/ns-allinone-2.31/ns-2.31dtsncc/dtsncc-scripts# ns dtsncc.tcl invalid command name "Agent/GPSR"

    while executing

"Agent/GPSR set planar_type_  1   "

    (file "dtsncc.tcl" line 233)

Does this mean that the gpsr protocol was not compiled correctly? How can I replace it in the tcl script by some other similar protocol that can allow the execution of the script to see if the make of the whole folder was successful?

[knudfl]

@Umair Chaudhry.

»» ns dtsncc.tcl invalid command name "Agent/GPSR" «« :
? Are you sure you are using the right 'ns' ?

1) gpsr is present in the Makefile.in (and Makefile)
156:    gpsr/gpsr_neighbor.o \
157:    gpsr/gpsr_sinklist.o \
158:    gpsr/gpsr.o \

2) tcl/lib/ :
lib/ns-lib.tcl:618:         gpsr {
lib/ns-lib.tcl:619:                    set ragent [$self create-gpsr-routing-agent $node]
lib/ns-mobilenode.tcl:217:      set gpsronly [string first "GPSR" [$agent info class]]
lib/ns-mobilenode.tcl:218:      if {$gpsronly != -1 } {
lib/ns-packet.tcl:184:  GPSR

3 : How to use the right executable 'ns' :
cd ns-2.31/
cp ns ns-dtncc   (if more than one version of "ns with dtsncc", add version : ns-dtncc-2)
sudo cp ns-dtncc /usr/local/bin/
... And do all simulations like :  ns-dtncc dtncc.tcl

I.e. you can only have one file by name 'ns'.
May be you by mistake added some *PATH text to .bashrc ?  Which is never required.
Just keep all ns-<name> in /usr/local/bin/ ...
... ( I usually have 200 times  ns-<name> in /usr/local/bin/ :
... I.e. i.e. we have about 200 extra ns2 protocols to maintain.)

@knudfl

1- copied 'ns' in folder 'ns2.31' to 'ns-org' and 'ns' in folder 'ns2.31dtsncc' to 'ns-dtsn' and placed a copy of 'ns-org' and 'ns-dtsn' into /usr/local/bin/

2- attached is a copy of my .bashrc .

3- running 'ns-dtsn simple.tcl' shows the nam window and everything along with the output shown in the attached file but running 'ns-dtsn dtsn-twoflows.tcl' and 'ns-dtsn cwnd.tcl' give the errors attached. Since you already have the folder, the location of the tcl files are also shown along with the errors so you may check them out.

Thank you
