Post #15, @ammal : Welcome to LQ.

Otcl and Tclcl : You will have to pretend you are compiling with an i686 OS:
Patch the file 'install' : ns226-install-64.patch .
... But if your OS is a contemporary Ubuntu version, the otcl build may fail:
»» undefined reference to symbol 'dlclose@@GLIBC_2.2.5' ««.
I.e. the latest libc6 versions no longer includes the old objects.

If you have an older Ubuntu version (Or any oldish OS) :
cd ns-allinone-2.26/
patch -p0 < ns226-install-64.patch
https://drive.google.com/file/d/0B7S...ew?usp=sharing
export CC=gcc34 CXX=g++34 && ./install
Not 'export CC=gcc34 CXX=g++34/ && ./install'

Please specify your Ubuntu version, if further issues.
And please tell why you want ns-2.26 .
( Many of the old additional protocols have been ported to a later ns2 version.)

Thank you for the help!

I followed the steps you suggested, but the build was, again, not successful. The error this time changed to:

I am using the ubuntu version 16.04(LTS) and, I guess, that might be the cause of failure? as you mentioned about the contemporary version.

why ns-2.26?
Actually, I am working on my academic project in which I need to create a wireless network scenario which uses ZigBee routing protocol (tree). I was looking for suggestions over the internet and found this page which says that it is supported by ns-2.26 and 2.27. So, I wanted to try it out on ns 2.26.

As per my understanding, Newer ns2 versions provide mac layer IEEE802.15.4 (wpan) implementation but not the (ZBR/ZTR) routing protocol.
Please correct me if I am wrong and kindly suggest what can be done here.

Thanks,

Assume Ubuntu 16.04 - amd64.

? Which {gcc34, g++34} packages did you install ?


About wpan :
WPAN was introduced in ns-2.28:
All ns-2.28 ..ns-2.36 have wpan as default 802.15.4 protocol =~Zigbee.

Re #17.
? May be you didn't install the ns2 prerequisites ?

sudo apt install g++ autoconf libtool libxmu-dev

The g++ install also installs the packages required for all other gcc / g++ versions.

Thanks kundfl!

Yes, your assumption is correct. I have got "Ubuntu 16.04 - amd64" installed on my system.

Which gcc packages I installed?
Earlier I installed the packages you have provided in reply#12, but when it did not work, then I installed latest versions thinking that the installation may got corrupted or something....

resulted into this :

About the ns2 prerequisites, Actually, I already have ns 2.35 working well and I could not find any instructions specific to 2.26, so I assumed that I got it covered... bad assumption?

For Wpan, I think I should now invest my time in newer version of ns2 to accomplish my work but I just wanted to run that ZBR implementation which is now missing in newer ns2 versions but they say is possible in ns2.(26&27). I have the installation files of wpan for ns2.26&27.

Please let me know if there are any suggestions for me on this.

Thanks! again.

Re #20.

Compilers listed in #11 (not #12) are i386 = 32bits.

You have a 64bits OS. Requires 64bits compilers :
compat-gcc34-3.4.6-ubuntu1204-1_amd64.deb compat-gcc-34-c++_3.4.6-20_amd64.deb
... Please uninstall the i386 gcc34/g++34 packages.

gcc34 https://drive.google.com/file/d/0B7S...ew?usp=sharing

g++34 https://drive.google.com/file/d/0B7S...ew?usp=sharing


Please explain why you want to use ns-2.26 for WPAN.

Hi knudfl,

Followed these steps:

1. Uninstalled gcc-34 and g++-34 32 bit versions
2. Installed the gcc 64-bit version using the files you shared.
3. Executed the command
which generated following output(error):
about which you mentioned in reply#16.

------------------------------------------
Why do I want to use 2.26 for w-pan?
My work is related to ZigBee Tree routing(ZTR) protocol. I first want to understand and simulate a network with ZTR as routing protocol in hierarchical Tree topology and then make some modifications/additions to the ZTR and compare the results about some network parameters.

Now, as we know that w-pan is a term generally used for combined phy+mac+nwk+app layer specification for IEEE802.15.* standard.
So, when I looked into w-pan folder in ns-2.35, I could only find files which by name seems to implement mac layer functionalities, but, there is no folder named as ZigBee or ZTR. So, I assumed that ns provides mac and (of-course) phy layer implementation but not the ZigBee routing protocol(nwk layer) implementation. With this assumption, I started to search the internet for ZTR's implementation related suggestions and work in ns2. Subsequently, I found this github page and the installation package of w-pan for ns2.26&27 and this page also mentions about the ZigBee routing protocol (not available in latest versions of ns). That is why I want to install ns2.26, and then install w-pan package in it, and then see how the w-pan of ns2.26, which also seems to include ZigBee routing protocol, is different from other newer versions such as ns2.35.

Though, I am a beginner with ns and my understanding here can be wrong, but I thought that the best way will be to try it myself. But, got caught up in ns2.26 installation. I hope that all this explanation here makes some sense. Your suggestions and comments please.

Thank you!

Re #22.

The text README says : Platforms supported ns2 version: 2.26 and 2.27 . EDIT see #24

So of course you will have to use a version from the current century. EDIT, see #24
'ns-allinone-2.26' is mostly 1999 code ... or earlier.

From version ns-allinone-2.27 you can use the {tcl tk otcl tclcl} from ns-allinone-2.34.
If the older versions are causing any trouble.
( {tcl tk otcl tclcl} change was done with ns-allinone-{2.27, 2.28} for some projects.)

Re #22.

The git site https://github.com/jridgewell/ns2 is ns-2.35.
See the file ns2/VERSION.
The file ns2/wpan/README is a leftover file from before wpan was included in ns2.
Is even in ns-2.36rc1/. Never edited.

Seems some TCP code was added : CTCP → jridgewell-NCTCP → jridgewell-NCTCP_ns235.patch
.. The patch shows the difference from a stock ns-2.35/ to jridgewell/ns2/
