About error of making animation of broadcastMAC_example

[Abir Hossain]

Dear
i would like to make an animation of the file broadcastMAC_example under the directory /src/aqua-sim-ng/examples/broadcastMAC_example but it shows error.

as
 
../scratch/broadcast_MAC.cc:179:77: error: invalid conversion from ‘int’ to ‘ns3::Node*’ [-fpermissive]
     anim.SetConstantPosition (nodes, devices.Get(0)->GetIfIndex(), 1.0 , 2.0);
                                                                             ^
/ns3/ptr.h:721:1: error:   initializing argument 1 of ‘ns3::Ptr<T>::Ptr(T*) [with T = ns3::Node]’ [-fpermissive]
 Ptr<T>::Ptr (T *ptr)

please help.

Dear Abir,

I do not know which ns-3 release you are using, but in the latest, the SetConstantPosition is defined as follows:

https://www.nsnam.org/docs/doxygen/classns3_1_1_animation_interface.html#adc75e56ec42c4b86b90b34f04cf52ee1

void ns3::AnimationInterface::SetConstantPosition	(	Ptr< Node >	n,
		double	x,
		double	y,
		double	z = 0
	)

This means that you need to pass the smart pointer for the node, and then its coordinates. 

Your call is not like this at all

anim.SetConstantPosition (nodes, devices.Get(0)->GetIfIndex(), 1.0 , 2.0);

However, I would recommend to use the native ns-3 mobility models to assign the position of the nodes instead of using the AnimationInterface to set it. 
From your code, I see that you already have tried to do this, and I do not understand why you need to use the SetConstantPosition.

Regards,

K.

Dear
My updated files creating nodes successfully. it creates a simulation error as

-----------Initializing simulation-----------

i could not recognize the problem. please help.

Abir,

we have said it hundreds of times, we can not provide support for models not in the main ns-3 codebase or out-dated releases.

The output from the compiler gives you the guidelines on how to go forward "Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>")."

Apart from the usual places to read (tutorial, manual, wiki) where there is information on how to debug your code, I would recommend also this year's training session on debugging.
