error with a new example, undefined reference

[mikacros]

Hi,
I've created a module for simulate a simplified satellite link and I
want to create an example.
In this example, I just want to see if a ping message exchange
works .
However, I got a error that I really don't understand in that case.

error :

device-example.cc.1.o -> build/src/satellite-device/examples/satellite-

From your code, it looks like your example depends on these modules:

core-module
network-module
applications-module
satellite-device
internet-module

Make sure that your module's example's wscript file:

src/satellite-device/examples/wscript

specifies that your example depends on the above modules by doing
something like this:

obj = bld.create_ns3_program('satellite-device-example', ['core',
'network', 'applications', 'satellite-device', 'internet'])
])
obj.source = 'satellite-device-example.cc'

thanks a lot

Hi 

I am new to NS-3 and had looked at the possibility of using NS-3 to model a satellite link. Is your module available in the repository?
