Configuring and working with NetTopo Simulator in Eclipse Kepler

Prerequisites:

The system should have either Java 6.0 or higher (i.e., both the JDK and JRE need to be installed), and the JAVA_HOME path should be set in the System variables.  

Configuration Procedure

Step 1:  Download and extract the Eclipse Kepler for JAVA by clicking here.

Step 2: Download Java3D and install in the Java installation directory by clicking here

Step 3:  Extract the Eclipse to C: Drive and run the Eclipse IDE.

Step 4:  Create CVS Project

               4.1 File -> New -> Project -> Project from CVS

               4.2  Set Host -> nettopo.cvs.sourceforge.net

                             Repository Path -> /cvsroot/nettopo/

                             User -> anonymous 

                             Password -> No password required (empty)

                             Connection type -> pserver

                             Port -> Use default port

                             click Next

              

                            

                   4.3  Project name -> NetTopo

 Step 5: Setting up Ant build and run

               

               5.1  In Window menu, select Preferences -> Ant -> Runtime

                   5.2  Select Ant Home Entries and Click on Add External Jar Files

                    

                   select

                  C:\Program Files\Java\jdk1.6.0\lib\tools.jar

                  C:\Program Files\Java\Java3D\1.5.2\lib\ext\j3dutils.jar

                  C:\Program Files\Java\Java3D\1.5.2\lib\ext\j3dcore.jar

                  C:\Program Files\Java\Java3D\1.5.2\lib\ext\vecmath.jar

                 and save the Entries.

Building and Running the NetTopo Project

Step 6:  In Run menu select Run Configurations 

               Project: NetTopo

               Main class: org.deri.nettopo.app.NetTopoApp

Step 7: In (X) argument tab enter the following under VM arguments

                -Djava.library.path=bin

Step 8: In the Package Explorer select NetTopo project and right click

              Run As -> Java Application -> NetTopo Application

Handling Segmentation Fault (Core Dumped) in ns-2

Programming c++ in ns-2 is a nightmare for beginners. It requires systematic planning and programming. Though the programming is systematically planned, even experienced programmers frequently encounter  bugs called "Segmentation fault (Core Dumped)" and Floating point exception (Core Dumped).  Generally, Floating point exception can be dealt with positive value in the denominator of an expression. This post explains how to debug these problem in ns2. The following procedure has been tested with ns-2.35.

Prerequisite: Your system should installed with gdb (GNU debugger).

Step 1: goto ns-allinone-2.35/ns-2.35, and edit the Makefile.in file

replace from

CCOPT    = @V_CCOPT@ 

to

CCOPT    = @V_CCOPT@ -g

Next, replace the following from

DEFINE    = -DTCP_DELAY_BIND_ALL -DNO_TK @V_DEFINE@ @V_DEFINES@ @DEFS@ -DNS_DIFFUSION -DSMAC_NO_SYNC -DCPP_NAMESPACE=@CPP_NAMESPACE@ -DUSE_SINGLE_ADDRESS_SPACE -Drng_test

to

DEFINE    = -DTCP_DELAY_BIND_ALL -DNO_TK @V_DEFINE@ @V_DEFINES@ @DEFS@ -DNS_DIFFUSION -DSMAC_NO_SYNC -DCPP_NAMESPACE=@CPP_NAMESPACE@ -DUSE_SINGLE_ADDRESS_SPACE -Drng_test -DNDEBUG -DDEBUG 

Step 2: Save the file and do the following

$ ./configure

$ make clean

$ make distclean

$ ./configure

$ make

$ sudo make install

Now debugging to your ns-2 is ready. If you have encountered the Segmentation fault bug while running any tcl file, then do the following

Step 3: goto the tcl folder and do the following

$ gdb ns

(gdb) run your_tcl_filename.tcl

TCL file runs with the above command and it stops at bug point showing the statement where the bug has present.
