[ndnSIM] Making a simple (?) custom example

[Muhammad Hosain Abdollahi Sabet]

Hi John,

It's good to have you here again!

​If you have configured ns-3 with *./waf configure --enable-examples* and
compiled it(I suppose you have), then you can run examples like you did (*--run
<name-of-the-example>*). Regardless of enabling examples in the first
step(./waf configure), you can always run your simulation scenario by
putting the file(here *ndn-tree-cs2-tracers.cc*) in */scratch*​ folder and
run it like normal (--run ndn-tree-cs2-tracers). And if you want to have
header/source files for some custom applications or something like that in
your simulation, you can have your custom folder in /examples(if you have
done --enable-examples) e.g.:
/examples/JB-custom-folder
and place the files into it, then #include them in you scenario file which
should be placed in /examples folder. Likewise you can do the same with
/scratch folder. I mean, you can have your custom directory
/scratch/JB-custom-folder
and put you custom files in it, then #include them in the scenario file.
Also you can use scenario-template:
https://github.com/named-data-ndnSIM/scenario-template
Just follow the instruction mentioned in the page.

No. Compiler is right :) SetContentStore is not a member of StackHelper.
You can check here:

​As you probably know, ndnSIM uses a different(older) version of NFD. NFD's
latest version is 0.5, while ndnSIM 2.1 is using 0.3.4 and ndnSIM 2.2 is
going to use 0.4. Of course you can try compiling NFD's latest version with
ndnSIM, ​but you will get many errors.

I hope my answer is not that complicated as it seems.

Thanks,
Sabet
