[SOLVED] Add new protocol in ns

s.arzandeh · 07-08-2013, 08:05 AM

dear all,
i add new protocol (named Buddy) to ns. i create a folder named Buddy and put 3 files (Buddy.cpp, Buddy.h and Buddy_packet.h) in it.
after i run make command error below appers:
Buddy.h: packet.h no such file or directory
Buddy.h: ip.h no such file or direstory

the compiler cannot detect the header file used in Buddy.h, although all header files are existed.

can anybody help me?

You have not resolve the locations of packet.h and ip.h. Find out if you have those files on your system, and where they are located. You then can edit your Makefile to add references to the directories where those files are located.

Somewhere in your Makefile should be the call to gcc, something like:

Code:

gcc -Wall $(LIB) $(INC) -c Buddy.cpp

Earlier in the file may be something defining your include paths, like:

Code:

LIB=-L/usr/lib/
INC=-I/usr/include/

Fix those lines in your Makefile to match what your environment or system requires and this should resolve these problems.

Another option is to forgo make and call gcc from the command line. You still will have to find the directories where your include files are located, but the call will look something like this:

Code:

gcc -o Buddy -I<directory> Buddy.cpp

I only add Buddy/Buddy.o \ in line 336

Makefile.txt : Add to line 76 : -I./Buddy

Then you can run $ make
.. and Buddy.o will be compiled into the executable 'ns'.

thanx

I suggest you grab a log of your make attempt and attach that to a reply so that the specific errors you're encountering can be viewed.

thanks dear,
i'm new to linux, if u mean i'm supposed to attach the output of my make command, below is the attachment:
thanks

The first things to resolve are to get the locations of packet.h, ip.h, timer-handler.h, agent.h, config.h, and scheduler.h known in your system. Find the directories where those files are located and add those to the include path in your Makefile. Add those paths to the section in your Makefile titled INCLUDES.

s.arzandeh · 07-09-2013, 10:23 AM

thanks dear,
i check the location of ip.h or packet.h for instance and both of them locate in /usr/src/ns-allinone-2.35/ns-2.35/common and the common folder already exists in makefile (-I./common)
so why still i have problem?

rtmistler · 07-09-2013, 10:30 AM

Below is the INCLUDE definitions from the Makefile you sent before, the path you mention is not in this Makefile. ./common is not the same as /usr/src/ns-allinone-2.35/ns-2.35/common.

Code:

INCLUDES = \
	-I.  \
	-I. \
	-I/usr/src/ns-allinone-2.35/tclcl-1.20 -I/usr/src/ns-allinone-2.35/otcl-1.14 -I/usr/src/ns-allinone-2.35/include -I/usr/src/ns-allinone-2.35/include -I/usr/src/ns-allinone-2.35/include -I/usr/include/pcap \
	-I./tcp -I./sctp -I./common -I./link -I./queue \
	-I./adc -I./apps -I./mac -I./mobile -I./trace \
	-I./routing -I./tools -I./classifier -I./mcast \
	-I./diffusion3/lib/main -I./diffusion3/lib \
	-I./diffusion3/lib/nr -I./diffusion3/ns \
	-I./diffusion3/filter_core -I./asim/ -I./qs \
	-I./diffserv -I./satellite \
	-I./wpan \
	-I./Buddy

# 5 .

Makefile(.txt) : Looks OK. Can't say what's wrong.

May be your "Buddy" code : Should be like ..

#include "packet.h"

I.e. not this : #include <packet.h>

knudfl · 07-09-2013, 12:33 PM

# 5 .

Suggest : Run the command $ make depend
.. before $ make

( You can read in line 598-599, your Makefile, what 'make depend' does.)

@rtmistler: i add the path of packet.h for instance into Makefile but still have same errors

@knudfl: after change <packet.h> to "packet.h" nothing changed

also i run make depend and error below happend:
make: *** No rule to make target `Buddy/Buddy.cc', needed by `depend'. Stop.

Dears please help me. i need to complie my code.

In one of every 1,000 builds of ns2 with a new protocol,
a similar <header not found> error can happen.

I never found out the real reason, but used a `workaround trick` :
Simply copy the "missing" headers to the Buddy/ folder from common/, etc. etc.

All the headers you will miss, are usually found inside ns-2.35/ .
Headers are easy to spot with the find command. $ find . -name <header>
