Using iperf from ns-3 source code instead of DCE source code

[Kun Win]

Good Morning,

I am trying to use iperf from within NS-3 source code (example: from "scratch" folder). I have been going though lot of suggestion here in the group such as

https://groups.google.com/g/ns-3-users/c/PjxNPO4SOwI

https://stackoverflow.com/questions/52918310/how-to-include-header-only-directory-to-run-ns-3

I still not be able to use "iperf" executable from within ''scratch' folder.

I would be really grateful, if someone could point be to the right direction. Or is it even possible?

sincerely,

Win

See the post I just sent a few seconds ago to another thread. If you
want to use iperf, you should put your program in DCE, not ns-3/scratch.

If you want to use a different version of iperf than the one that bake
provides, then you will want to edit the bakeconf.xml to build your
different iperf source code so that the binary is found in bake's
'build/bin_dce/' directory.

Hi Tom,

Thank you for answering my question. I already read your answer in another thread. That really help because I was trying to do the exact same thing, by using iperf from ns-3 source code and not from dce source code. If it is possible, would you mind explaining a bit more, why we can't just add a path to bake/build to wscript while compiling ns3 source code (so that it could see dce-module.h and *.so)? From what I observed, the DCE uses modules from NS3 to compile, but if those paths was added when compiling NS3, the program in scratch folder should be able to see the dce code? (I already tried that and get an error, for instance: [undefined reference to `ns3::DceManagerHelper::DceManagerHelper()'])

I am quite new to this simulation and already manage to make iperf3 works with DCE. I am trying this out so that it would be easier for other to just use NS3 and iperf without having to worry about which source code folder the custom program is located.

Sincerely,

Win
