I have been using ns2 and nam for a long time on my ubuntu. Now I have to apply a patch (OSPF) to it. I have been searching for how to apply a patch in linux (as I'm kind of new in it) and all I got was:
1) $ tar xvf ns-allinone-2.35.tar.gz
2) $ cd ns-allinone-2.35/
3) $ ln -s ns-2.35/ ns-2.34
... Then the patch will work, except for one line. (commom/packet.h).
4) $ patch -p0 < 10-ospf4ns2.34-base.patch
http://sourceforge.net/projects/ospf4ns/
5) Replace commom/packet.h with the attached "packet.h" : Edited by hand.
6) export CC=gcc44 CXX=g++44 && ./install
I untared the tar file, copied the .patch file in the ns-allinone-2.35 folder called 10-ospf4ns2.34-base.patch, gone to the directory in a terminal, used ln -s ns-2.35/ ns-2.34 and then patched using line 4. After that I have these messages:
The next patch would create the file ns-2.34/classifier/classifier-mtopology.cc,
which already exists! Assume -R? [n] y
patching file ns-2.34/classifier/classifier-mtopology.cc
The next patch would create the file ns-2.34/classifier/classifier-mtopology.h,
which already exists! Assume -R? [n] y
patching file ns-2.34/classifier/classifier-mtopology.h
can't find file to patch at input line 92
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|--- ns-2.34.old/common/agent.cc 2009-06-14 18:35:45.000000000 +0100
|+++ ns-2.34/common/agent.cc 2010-02-26 23:34:33.161063590 +0000
--------------------------
File to patch:
After this I don't know what to do. What file should I patch? There is no classifier-mtopology.h in ns-2.34.
And after that, which packet.h should I replace with the specified new packet.h? Because there are several common folders. Any help would be much appreciated cause I'm a novice in linux.
