Segmentation Fault with GPSR-HLS (hls.tcl)
 
I patched NS 2.33 for GPSR using http://www.cn.uni-duesseldorf.de/alu.../hls-ns2-patch When I run hls.tcl in hls/utils/

it gives me
Sorting lists done ...
Segmentation Fault (core dumped)

When I run the nam file it runs only for 1 second whereas I set the time to 200 secs.

Any help is highly appreciated.

Welcome to LQ.

Segmentation Fault : Looks like a failed build of ns-2.33 / GPSR-hls ?
Which OS are you using ? 1) $ cat /etc/*release* ; 2) uname -m

Or may be you edited the file 'hls.tcl' ?
There is no "out.nam" from the original 'hls.tcl'.

#3 : GPSR-hls can be built on Ubuntu 12.10 .

a) cd ns-allinone-2.33/ns-2.33/
b) patch -p1 < ns-2.33-hls.patch
c) tar xvf hls-files-ns233.tar.gz
d) cd ../
e) export CC=gcc41 CXX=g++41 && ./install

f) cd ns-2.33/ ; ./ns : OK.
sudo cp ns /usr/local/bin/
cd hls-utils/ ; ns hls.tcl : OK.
ns ssoumayaa.tcl : OK.
bash run_small.bat : OK.

I have made the patch and it worked fine without any errors.
I also install greedy routing protocol
http://www.cse.ohio-state.edu/~sakai...s2_greedy.html

but scripts for this protocol give the same error as well.

I guess there might be some problem with my ns-2.33 installation. I had one more ns-2.33 installation in other directory that got corrupt. No sure what is causing the problem. I will test with AODV, DSDV and let you know.

# 5 .

You will have to be very careful when you add more than one patch/extra protocol.
Some patches will make conflicting changes to the files.

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

but got the following error

Fixed #7

export CC=/usr/bin/gcc-4.7 CXX=g++-4.7

I don't know how but after the last step

Quote:
export CC=/usr/bin/gcc-4.7 CXX=g++-4.7
I did ./install

and now everthing works fine. No segmentation fault.
Thanks Knudfl for your support. I appreciate that.
