could anyone pls help me out how to get rid out of this error. (I download MIT/uAMPS leach file)

# 527

$ cd ns-2.34/tcl/ex/ && ns wireless.tcl
mandatory arguments : [-x MAXX] [-y MAXY]

I.e. you will have to run that file from the /ex/ folder.
And use the right options.
Example : $ ns wireless.tcl -x 300 -y 300

hi

I am using ubuntu 13.04 (64 bit, lower versions are not compatible)
I have installed ns-2.35 and ns-234-leach and changed all the addresses in leach-setup.sh, which worked without errors.
when I had run wireless.tcl after making changes in x,y,number of nodes etc it gave me some results when PROTOCOL = DSDV, but when I changed it to LEACH, it gave me the same error as post #1. I have gone through the procedure that followed... I installed GCC-4.3/g++-4.3 manually, but to no use.
when I "make" it, it gave me an error: and also after making changes in Makefile and Makefile.in as CC=gcc-4.3 and CPP=g++-4.3, when I ./configure, it changes back to CC=gcc and CPP=g++

when i m putting make command i got the error like
make: g++-4.3:Command not found
make: ***[tools/random.o] Error 127

what is this error

#529, #530 .

'gcc-4.3' used to work some years ago. ( Old Ubuntu's ).
Updates changed that.
Please use gcc / g++ version 4.1.2 or 3.4.6 .

#529, Ubuntu 13.04 - 64 :
No gcc-4.1 / g++-4.1, use gcc/g++ version 3.4.6 .
Or better : Install a 32bits OS : ! ns2 is for a 32bits OS !
A 64bits OS will cause reduced functionality /
Inferior validate result.
** gcc34 / g++34, 64bits → post #11 here :
http://www.linuxquestions.org/questi...4175453599/#11

#530 : # yum install compat-gcc-34-c++
#529, #530 : Building ns2 : (not ns-2.35)
$ export CC=gcc34 CXX=g++34 && ./install

hey knudfl, thanx for replying.

I follwed the instructions given in the link provided by you, but there were two issues:
I could not find a line with "./configure --build" in the "install file, which I could edit, (though I have ns2.35 installed already)...
then after installing both the gcc ang g++ given in the links provided in the post, i did
which ended in the error, which i have already specified above

# 532 .

The "May Tamer leach" files that you are using are for ns-2.34 .
May not work in ns-2.35 .

Ubuntu 13.04 , ns-2.35 : Please use gcc-4.4 / g++-4.4 :
$ sudo apt-get install g++-4.4

Building ns-allinone-2.35 :
$ export CC=gcc-4.4 CXX=g++-4.4 && ./install

that I have already tried, I had gcc4.4 and g++4.4, though tried again.
gave the same error

# 534.

No leach patch or leach+pegasis patch seem to work in ns-2.35 :
Use ns-2.34 ! The good news :
You can have as many versions of ns-allinone-2.xx as you want,
installed at the same time.
But ! Do not add any path text to .bashrc !

Latest and most versatile is the leach+pegasis patching :
Starts in this thread, post #289.
All "Pegasis" http://www.linuxquestions.org/questions/tags/pegasis/

Leach-pegasis, latest = exidus-pegasis-leach-ns234-patch.2.tar.gz

thanks knudfl...
I'll try that and would let you know about the same... and one more thing...do I need to uninstall ns-2.35, if not then while giving ns command how would i know which ns version am i working on? and does it work properly on ubuntu 13.04 as I cannot come down to a 32 bit ubuntu, as my dual boot windows machine do not recognize it tried the installation with ubuntu 12.04 but failed.

# 536 .
No. But you can rename / save the executable 'ns' as e.g. 'ns235'.
The idea of having multiple ns2 installs is that you have :
/usr/local/{ ns ns235 ns-<name1> ns-<name2> ns-<name3> } etc.
.. And better delete what you added to .bashrc.

LEACH is an exception : Requires an executable by name 'ns'.
( Unless you edit the test scripts to ns-<new-name> ).


No problem compiling "leach-pegasis" in Ubuntu 13.04 - 64.
I tested that a couple of days ago :
exidus-pegasis-leach-ns234-patch.2.tar.gz
The gcc34 / g++34, 64bits was used. See #531.

Dear Friend,
I Know this could be silly question for all of you but i am little bit confuse between both them.
I want to know that LEACH Routing Protocol is only use over sensor network or mobile adhoc network or we can use leach for both.

thanks kundfl,
now it seems to be working after following all the above mentioned instructions and after making changes in the paths and variables... but when I run the wireless.tcl it gives me following error, copying everything:
it was opt(max_dist) before I changed it to $max_dist and gave a value as but when I do that it gives me an errorI looked for the error and followed http://mailman.isi.edu/pipermail/ns-...ay/068103.html
but it also gave me the same error...

eureka eureka eureka !!!!!

hey,

got the last issue solved, the problem was $max_dist was local vaiable and was needed to be chages at 3 places (I did it only once)
got a beautiful line below saying " simulation complete"

thank you for your timely help (specially knudfl) ...
(might need more help in a short while...)
