# 15 .

The right compiler for Ubuntu 12.04 - i686 is now :
gcc41-compat-4.1.2.ubu1204_i386.deb →
https://docs.google.com/open?id=0B7S...lNURldUenRyb3c

Removing the "1210" gcc41 : $ sudo dpkg -r gcc41-compat
Install "1204" : $ sudo dpkg -i gcc41-compat-4.1.2.ubu1204_i386.deb

No reboot required. The PATH script /etc/profile.d/gcc41.sh is the same.

I have removed the old package and installed the new one.
But I am getting the same error when I try "export CC=gcc41 CXX=g++41 && ./install"
Below is the complete trace when I execute

# export CC=gcc41 CXX=g++41 && ./install

# 17 .
OK, that's kind of an error. You should do ns2 builds in /home/name/<folder>/,
.. and no "root" commands ! ( Except for # make install ).
*** `root´ is for administrative tasks only.

If you insist in using `root´, you will need gcc41/g++41 in root's PATH :
$ cd /usr/bin/
# ln -s ../gcc41/bin/gcc41
# ln -s ../gcc41/bin/g++41

Thanks for the reply. I have istalled gcc41 and g++41 as a non-root user.
After this I installed ns-2.29 as you have mentioned from the scratch.
But when I run "ns-nist-pmipv6 pmip.tcl" I am getting the same segmentation error.

num_nodes is set 6

My system is 64 bit and I have installed 32 bit ubuntu 12.04. Is there any connection with 64 bit machine or with ubuntu 12.04?
or else pls let me know the OS in which you have executed "pmip.tcl" code.

# 19 .

Most computers are 64bits. Since 2004 - 2005.
No problem at using a 32bits OS with a 64bits processor.
But : ns-2.29 + ns-2.29-nist-mob-022707 + pmip6-for-ns-2.29-nist.patch
.. don't seem to work with Ubuntu 12.04 : Cannot compile with g++41 .
( Because the nistmob + pmip files are far older than ns-2.29.3 ).
And cannot link if using the older compiler g++34 (gcc version 3.4.6).

( Actually 64bits did once work with the above : CentOS 5.x )
The reliable choice is usually the 32bits CentOS 6.5 .

Please read the threads. May also work with a later 32bits Ubuntu.

Thank you so much for your timely help.
I will do with cent OS. If something goes wrong I will trouble you again.. hope you dont mind

Hello.. I am back

Would you pls guide me in installing gcc41 & g++41 in CentOS 6.4?

Thanks

# 22 .

A similar compiler is already available :
# yum install compat-gcc-34-c++

Then the build command will be :
$ export CC=gcc34 CXX=g++34 && ./install

(It's Ubuntu only, that has the "g++34 issues" with `ns-2.29-nist-mob´, I think.)

-

I have installed gcc34 as root
then I have executed #export CC=gcc34 CXX=g++34 && ./install

It is throwing lots of errors. Please find the attachment of the errors.
I think its problem with gcc. Could you please help?

# 24 .
It better be : # yum install compat-gcc-34-c++

Start from scratch in a new folder in /home/<name>/.
And no root commands ! (Except 'make install'.)
See the above posts : `$´ is the user prompt. `#´ is root.

Use the right ns-2.29 = 'ns-allinone-2.29.3.tar.gz'
http://sourceforge.net/projects/nsna...allinone-2.29/

$ tar xvf ns-allinone-2.29.3.tar.gz
$ cd ns-allinone-2.29/
$ tar xvf ns-2.29-nist-mob-022707.tgz
$ patch -p0 < pmip6-for-ns-2.29-nist.patch
$ export CC=gcc34 CXX=g++34 && ./install
$ cd ns-2.29/
# make install

-

Just did every thing from scratch as you have mentioned but ending up at the same point.. getting lots of errors while it is installing tk8.4.11.

please let me know how to solve this.

# 26.

The ns-2.29.3 { tcl8.4.11/, tk8.4.11/, otcl-1.11/ }
.. will build equally OK with either gcc-3.4.6 or gcc-4.4.x .
.. So your `tk8.4.11´ issues are not compiler related.

May be you forgot to install all the required prerequisites ?
# yum install \
gcc-c++ compat-gcc-34-c++ autoconf automake libtool libXmu-devel

Can also be a corrupt ns-allinone-2.29.3.tar.gz ?
Delete the one you downloaded, and get a new one ..

Finally I have installed ns and executed pmip.tcl
Got the trace output..! Problem was with prerequisites..
You are doing a great job of guiding newbies like me..
Thanks a lot

I really want to learn linux concepts in depth..
would you please give me some suggestions, links to Internet resources etc.

Best way of learning : Use a Linux OS.
Reading about it is OK, but things are memorized much easier,
when they are used in a real situation.

RUTE is often suggested to be good to start with :

Hello,
I installed ns2.29 on ubuntu 13.10 32 bits and i added the patch successfully to ns2.29.
url:https://sites.google.com/site/pmip6n...ns-2/downloads
when trying to execute pmip.tcl i got the problem with the tracing in the line:
(void)Tcl_Write(channel_, wrk_, n + 1); (basetrace.cc)
size is the size of the wrk_ variable that i am printing.
the problem is:
