Thank you for the suggestion.

I tested the "test4wcett.tcl" on the ubuntu10.10 yesterday,and it went smoothly.
The strange thing is that the "make clean && make depend && make" process and "$ns test4wcett.tcl" went fine with gcc4.4 g++4.4.I had thought it would abort without "export CC=gcc41 CXX=g++41".How could that be?

# 16 .
1) That's because you kept the Makefile. Which probably says :
Line 36 : CC = gcc41
Line 37 : CPP = g++41

2) 'make depend' is not required when ./install has been run.

3) And finally : No reason at all to do "make clean && make".
** Please read post #6. The procedure is:
a) cd ns-allinone-2.31/
b) tar xvf crcn-ns2.31.tar.gz
c) export CC=gcc41 CXX=g++41 && ./install

Hi sir

What about Ubuntu12.04 64bit? is that compatible with ns2.31 and crcn.
I have to use NS2 to simulate crcn, but there are always some problems when I was using ns2.
Please help me.

Thanks a lot

Post # 18, @Shuyu : Welcome to LQ.

Ubuntu recommends the 32bits version : For everything.
All ns2 is for a 32bits OS.
Some versions of ns-allione-2.xx, and some patches can be used on a 64bits OS.
But : The result is always a poor validation ('make test') result !

For all { ns -2.26 .. 2.33 (2.34) }, the 64bits gcc34 / g++34 can be used :
$ sudo dpkg -i compat-gcc34-3.4.6-ubuntu1204-1_amd64.deb compat-gcc-34-c++_3.4.6-20_amd64.deb
gcc34 https://docs.google.com/file/d/0B7S2...it?usp=sharing
g++34 https://docs.google.com/file/d/0B7S2...it?usp=sharing

a) cd ns-allinone-2.31/
b) tar xvf crcn-ns2.31.tar.gz
c) export CC=gcc34 CXX=g++34 && ./install

Thanks sir

If the some tests failed, Did it mean that I cannot use NS2?

Thanks

# 20 .

Some tests will often fail, also with a 32bits OS.


So it's do and try : There is a good chance that everything will work.

Thanks.

BTW, if I don't use crcn, can I simulate cognitive radio by adding new protocol in ns2?

Shuyu

# 22 .

Which new protocol ?

I will use ns2 to simulate cognitive radio ad hoc networks to consider new routing protocols designed by myself. may be based on AODV protocol.

# 22, # 24 .

Why not use a later ns2 version for your projects ?
( ns-2.34 or ns-2.35 ).
I.e. ns-2.30, 2.31, 2.32 are not amongst the best versions, AFAIK.

Anyway, good luck with your new protocols.

P.S. : There are some hits with Google .. ns2 "cognitive radio ad hoc network" ..

The main problem is the CRCN patch can't be used on ns2.35. I consider that using ns2.31 with CRCN may be easier.

Thanks

can you give a new patch ,the old link is overdue.

thank you very much

* CentOS 6 can hopefully still be used for CRCN. (Updates may spoil the CRCN usability?)
* No new Ubuntu OS can be used !
