1 Direction of building NS2 platform using Cygwin under Windows OS Huang Xuguang Introduction This document aims to give the direction of building NS2 using Cygwin under windows os. The procedures and common errors are listed in this document. The software and source codes we need are: 2. Steps Cygwin: Downloaded from NS2 source code: Downloaded from version: ns-allinone-2.27.tar.gz Patch of NS2: Downloaded from Patch of tk: Downloaded from version: tk tkbind.patch LEACH source code: Downloaded 1> Install Cygwin It is easy to install Cygwin under windows os. a. First, get the software from b. Launch setup.

2 c. Here you must install these packages because NS2 needs them: XFree86-base, XFree86-bin, XFree86-prog, XFree86-lib, XFree86-etc, make, patch, perl, gcc, gcc-g++, gawk, gnuplot, tar and gzip d. After finishing the setup, you can start Cygwin and the screen should be like this:

3 Then checking the root of Cygwin, making sure there are one folder named home and there are three hidden files in home/{username} which are.bashrc,.bashrc_profile and.inputrc. no home folder and no three hidden files Check the Environment Variable of your computer; delete the entry which named HOME 2> Install NS2 a. Unzip the source code of NS2 and it includes these files: tar xvfz ns-allinone-2.27.tar.gz TCL release (required component) TK release (required component) Otcl release 1.8 (required component) TclCL release 1.15 (required component) Ns release 2.27 (required component) Nam release 1.10 (optional component) Xgraph version 12.1 (optional component) CWeb (optional component) SGB (optional component, builds sgblib for all UNIX type platforms) Gt-itm (optional component) Zlib version (optional, but required when Nam is used) b. Install patch. Before we excuse the compilation process, we d better to install patch of NS2 to avoid mistakes. Download the patch named ns227-gcc34.patch and put it in the same dir with ns-allinone Install it. patch -p0 <ns227-gcc34.patch c. Enter the dir of ns2 and install it. cd ns-allinone-2.27./install

4 d. Finish compiling. Generally, the compilation process will cost about 4 hours (depended on your computer). If you finish this step successfully, you will see this: During this step, you would meet many problems. I list the common errors I met and give the salvations. Tcl is not part of the ns project Modify the following files, find the words.relid'` and use.relid` instead. ns-allinone-2.28\tcl8.4.5\unix\configure ns-allinone-2.28\tcl8.4.5\unix\tcl.m4 ns-allinone-2.28\tk8.4.5\unix\configure ns-allinone-2.28\tk8.4.5\unix\tcl.m4 ns-allinone-2.28\otcl-1.8\configure e. Setting environment variables. Edit the file.bashrc which is a hidden file in your home/{username} folder and insert these sentences: export NS_HOME=`pwd`/ns-allinone-2.27 export PATH=$NS_HOME/tcl8.4.5/unix:$NS_HOME/tk8.4.5/unix:$NS_HOME/bin:$PATH export LD_LIBRARY_PATH=$NS_HOME/tcl8.4.5/unix:$NS_HOME/tk8.4.5/unix:$NS_HOME/otcl-1.8:$N S_HOME/lib:$LD_LIBRARY_PATH export TCL_LIBRARY=$NS_HOME/tcl8.4.5/library f. Test NS2. Now, you have finished installing NS2. You can use an example to test NS2. Start xwindow startxwin.bat

5 Launch the example cd ns-allinone-2.27/ns-2.27/ns-tutorial/examples ns example2.tcl nam: no such file or directory There are two methods: 1. Check the folder ns-allinone-2.28/nam-1.11, copy nam.exe to ns-allinone-2.28/bin if it exists. 2. Recompile the nam if there is no nam.exe in this catalog ns-allinone-2.28/nam Edit the file agent.h under nam-1.11/agent.h Change NULL to 0 in line 73. Run./configure; make Executing the example and you would see:

6 Congratulations if you can see these two windows! You have installed NS2 sucessfully. 3> Loading LEACH a. Dowload LEACH source code and put it under ns-allinone-2.27/ns Unzip the package. gunzip mit.tar.gz tar -xvf mit.tar b. Modify makefile file. Find the paragraph beginning with DEFINE, add -DMIT_uAMPS in its end. Find the paragraph beginning with INCLUDES, add one line -I./mit/rca I./mit/uAMPS in its end. Find the line gaf/gaf.o \, add these before it. mit/rca/energy.o mit/rca/rcagent.o \ mit/rca/rca-ll.o mit/rca/resource.o \ mac/mac-sensor-timers.o mac/mac-sensor.o mit/uamps/bsagent.o \ The file should be like this: c. Set environment variable Edit the file.bashrc which is under the catalog home/{username}. Add export RCA_LIBRARY={$NS_HOME}/ns-allinone-2.27/ns-2.27/mit/rca export uamps_library={$ns_home}/ns-allinone-2.27/ns-2.27/mit/uamps Edit wireless-phy.cc which is under ns-allinone-2.27/ns-2.27/mac, add the definition #define min(a,b) (((a)>(b))?(b):(a)) behind the sentence #define max(a,b) (((a)<(b))?(b):(a)) d. Compile the LEACH make clean make To compile the LEACH would cost about 10 to 30 minutes (depend on your computer). After this step, you can run an example to test LEACH../test

7 LEACH is successfully installed if you see this: line3: ns:command not found 1. Modify./test file, put the line./leach_test under the line cd../../. It looks like this: sleep 2 cd../.././leach_test 2. Modify./leach_test file, add RCA_LIBRARY=mit/rca export RCA_LIBRARY uamps_library=mit/uamps export uamps_library before the line ns tcl/ex/wireless.tcl \ e. Check the leach.err file under ns-allinone-2.27\ns-2.27\mit\leach_sims, the content would be this if LEACH works well.
