Compile Repeatation

After doing any changes in .cc file;

From terminal:

go to:->       cd ns-allinone2.35/ns-2.35

run:->         make clean

                   ./configure

                   make

                   sudo make install

How to re-compile NS2:

http://nshubforum.com/post/how-to-recompile-ns2

 NS2 need to be recompiled in two cases.

1. When modifying the existing algorithm

By using same header and source files

2. When adding new files/Protocols

 By adding new header and source files

 Modifying the Existing Algorithm:

Step 1: Change the existing algorithm.

Step 2: execute the following command

make clean

make depend

make

Compilation will be success if there are no errors in the modified code and NS will be created.

Step 3: Run TCL script for the modified algorithm.

Adding New Protocol:

Step 1: Create new header and source files for new proposed algorithm.  

Step 2: Put these files inside respective folder /home/user/ns-allinone-2.--/ns-2.--/

Step 3: Need to place that information in Makefile.in (in ns-allinone-2.--/ns-2.--/). Open Makefile.in using any editor (usually vi or gedit) and add the folder information to the OBJ_CC variable)

Step 5: Put new proposed algorithm information anywhere inside the OBJ_CC variable

For example:  "propalgo/propalgo.o  \"

Step 6: After editing the file entry, follow these steps:

1.                   Go to /home/user/ns-allinone-2.--/ns-2.--/

2.                   ./configure   // replace Makefile  with modified one.)

3.                    make clean //(*optional) use this, If you want to recompile the whole ns2.

4.                    make  //this will make all object files which are missing

 Compilation will be success if there are no errors in the modified code and NS will be created.

Step 7: Run TCL script for the new protocol.

=================================================

$ sudo apt-get update

$ sudo apt-get upgrade

$ sudo apt-get install

=================================================

$  cd ns-allinone-2.35/

$ ./install

$ cd ns-2.35

$ ./configure                     (replace Makefile  with modified one.)  or next line

$ sudo make install

if any problem, then

$ make clean                    (*optional -  use this, If you want to recompile the whole ns2.)

$ make                            (this will make all object files which are missing)

$ sudo make install
