hii there
I am new with the NS2 simulator and I have install Ubuntu 12.04 on vmwear and NS2.33

ali@ubuntu:~$ which ns
/usr/local/bin/ns


in order to implement the gpsr protocol and I have this error:

ali@ubuntu:~/ns-allinone-2.33/hls-utils$ ns-hls hls.tcl
invalid command name "Agent/GPSR"
while executing
"Agent/GPSR set bdesync_ 0.5 "
(file "hls.tcl" line 6)
and I am follow these steps that posts
#23
http://www.linuxquestions.org/questi...526/page2.html

and when I apply this comment
&& export CC=gcc-4.1 CXX=g++-4.1 && ./install

I get this error

Tcl is not part of the ns project. Please see www.Scriptics.com
to see if they have a fix for your platform.

please if you can help and provide me the sequence of steps that I should follow to implement the protocol.

Welcome to LQ.

#23 http://www.linuxquestions.org/questi...526/page2.html #23
... says Ubuntu 10.04 : There is no gcc-4.1/g++-4.1 in Ubuntu 12.04 .

For 32bits (i686) Ubuntu 12.04 please use gcc41 / g++41, #18 here :
http://www.linuxquestions.org/questi...022/page2.html
$ sudo dpkg -i gcc41-compat-4.1.2.ubu1204_i386.deb g++41-compat-4.1.2_i386.deb
.. Then reboot, and the new compiler can be used :

$ cd ns-allinone-2.33/ && export CC=gcc41 CXX=g++41 && ./install

thanks Mr.knudfl for the quick response

actually I am new with NS2 and ubuntu and now I am interesting in this topic specially with ad hoc network and related protocols
so please if you can help me and show to me the best way to learn about this topic and how I can implement these protocols by using the NS2 and ubuntu

by the way sir if it is possible tell me the web site that i can use to download : ubuntu 12.04 32bits (i686)
and I plan to
install
1: ubuntu 12.04 32bits (i686)
2: install NS2.33 allinone
3: implement gpsr-hls protocol

this environment it is ok for this protocol

thanks and regards

# 3 .
1) I thought you already had Ubuntu 12.04 ? Anyway, here it is ...
http://www.ubuntu.com/download/deskt...32&release=lts
>>> http://mirror.easyspeedy.com/ubuntu-...sktop-i386.iso
>> ubuntu-12.04.4-desktop-i386.iso


2 + 3) When you have installed the compilers, see post #2, it is :
Build ns-allinone-2.33 with GPSR-hls :
$ cd ns-allinone-2.33/ns-2.33/ && patch -p1 < ns-2.33-hls.patch
$ tar xvf hls-files-ns233.tar.gz && cd ../
$ export CC=gcc41 CXX=g++41 && ./install
**** EDIT : See post #5.

Install the executable 'ns(-hls)' :
$ cd ns-2.33/
$ sudo make install
... And to be sure that the 'ns' isn't confused with other "ns" please do :
$ cp ns ns-hls
$ sudo cp ns-hls /usr/local/bin/
... Important : All gpsr-hls simulations can be run with $ ns-hls file.tcl
That's it. Don't do anything more. (Like adding something to .bashrc ).

P.S. : There is actually a later set of "hls-files" for increased simplicity ,
gpsr-hls-ns233-patching.tar.bz2 , with everything included :
* https://drive.google.com/file/d/0B7S...it?usp=sharing

... Then the complete build is :

$ cd ns-allinone-2.33/
$ tar xvf gpsr-hls-ns233-patching.tar.bz2
$ export CC=gcc41 CXX=g++41 && ./install

Hii Mr.knudfl

I already did all the steps your mention the the posts # 2 and #5 and every thing completed
also I am already download the gpsr-hls-examples-0113.tar.gz and extract it inside ns-allinone-2.33

and also I got this error when I tried to execute the run.tcl file

I hope you can help me to solve this problem

# 6 .
Read post #4 :
Make a copy of the 'ns -gpsr' to a new name : $ cp ns ns-hls
And : $ sudo cp ns-hls /usr/local/bin/
... I.e. the simulation must be run with $ ns-hls ssoumayaa-0.tcl


# 7 .
That's a typical error when the wrong 'ns' is used.
Use "ns-hls" or "ns-gpsr-hls" or whatever name you like.

("invalid command name "Agent/" can also be a failed build.)

Please read http://www.linuxquestions.org/questions/tags/gpsr/
