Welcome to LQ.

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

If you have done the patching correctly :
$ cd ns-allinone-2.31/ && tar xvf crcn-ns2.31.tar.gz
https://drive.google.com/file/d/0B7S...it?usp=sharing
... I guess you are using the wrong compiler.
ns-allinone-2.31 requires gcc/g++ version 4.1.2 .
Or version 3.4.6 if it's a Fedora OS.

Please specify your OS :
1) uname -m <Enter>
2) cat /etc/*release* <Enter>

Thanks for your reply.I am using fedora 17 for ns2.31 and CRCN patch.

As you said.I tried doing and i get :

[lab@localhost ~]$ uname -m
i686
[lab@localhost ~]$ cat/etc/*release*
bash: cat/etc/*release*: No such file or directory
[lab@localhost ~]$

but the question is: i am using CRCN.jar for CRCN GUI .Can both crcn-ns2.31.tar.gz and CRCN.jar be used for CRCN GUI??? am i doing wrong??

if i say yum install gcc-c++ then it shows the following:


Trying other mirror.
http://mirrors.hustunique.com/rpmfus...ta/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirrors.hustunique.com; Unknown error"
Trying other mirror.

Package gcc-c++-4.7.2-2.fc17.i686 already installed and latest version
Nothing to do

Post #5 . Please read post #3 : ".. version 3.4.6 if it's a Fedora OS."

I.e. # yum install compat-gcc-34-c++

The install commands are then ..
1) $ cd ns-allinone-2.31/ && tar xvf crcn-ns2.31.tar.gz
2) $ export CC=gcc34 CXX=g++34 && ./install
.... which you would know if you did what's suggested in #3 :
! ! ! read http://www.linuxquestions.org/questions/tags/crcn/



Post #4 : `CRCN.jar' is a GUI application.
"crcn-ns2.31.tar.gz" is simply the CRCN patch repacked for an easier install.

when i do as above and ./install i get the following:


* Build Tk8.4.14
============================================================
./install: line 447: ./configure: Permission denied
tk8.3.2 configuration failed! Exiting ...
Tk is not part of the ns project. Please see www.Scriptics.com
to see if they have a fix for your platform.
[lab@localhost ns-allinone-2.31]$


I had tk8.4.14 installed previously.what should i do??

# 7 .
Quote:
./install: line 447: ./configure: Permission denied
"Permission denied" means that you probably corrupted ns-allinone-2**
at unpack. Did you do tar xvf ns-allinone-2.31.tar.gz as root ?

Solution : Delete ns-allinone-2.31/ and start from scratch in
/home/leki/(<folder>) , and don't use "su" for any command.
`root' permissions are to be used only for 'make install'.

hi..I started from beginning as you said.
My ns and nam seems to work fine but i got following error:


validate overall report: some tests failed:
./test-all-newreno ./test-all-tcpOptions ./test-all-tcpVariants ./test-all-aimd ./test-all-frto ./test-all-quickstart ./test-all-diffusion3 ./test-all-smac ./test-all-smac-multihop ./test-all-manual-routing ./test-all-session ./test-all-links ./test-all-wireless-shadowing ./test-all-wireless-lan-aodv ./test-all-wireless-tdma ./test-all-wireless-gridkeeper ./test-all-wireless-diffusion ./test-all-wireless-lan-newnode ./test-all-satellite ./test-all-WLtutorial ./test-all-tagged-trace ./test-all-wpan ./test-all-energy
to re-run a specific test, cd tcl/test; ./test-all-TEST-NAME
Notice that some tests in webcache will fail on freebsd when -O is turned on.
This is due to some event reordering, which will disappear when -g is turned on.


what should i do??will it lead to any serious problems if i dont correct it???

# 11 .

* `i586' only means that the package was compiled to work also with i586.

* i386, i486, i586, i686 packages all work equally OK with i686.
