linking problem

Hi, @saburhb @debashish216
Thanks for your detailed instructions, now I am facing the same issue as others, there might be some issues in "uav-net-sim" file which I could not run some examples. I tried to comment out the "#include <syslog.h>" in the czmq_prelude.h file but the issue still remain.
I am looking forward to your suggestions.
Much appreciate!

Can you try running "./waf configure" first in ns-3.27/ folder and then execute ./waf --run command.

Hi @saburhb,
I tried this method however the problem still remain. I also tried to reinstall the ns3 but the problem still unsolved

Hi, @saburhb
Thanks for your suggestions. For now, I can run some examples using ns3 only and the FlyNetSim_direct_no_ns3.py works fine. However the FlyNetSim.py still not work. I checked your recent suggestions and there are some questions about your recent comments:

At the first step, you said try to run ns3 alone, I considered run "uav-net-sim.cc" under the ns3 folder,

Is this image shows the ns-3 has been run successfully?

At the second step, you said to redirect the output of FlyNetSim.py file to the log file. To be honest, I am not sure what is the output of this FlyNetSim.py file.
I am looking for your further suggestions!
Much appreciate!!!

As you confirmed your ns3 works independently and also FlyNetSim_direct_no_ns3.py also works independently but FlyNetSim.py which combines the two of them does not work, the only problem seems to be the path. If you open your FlyNetSim.py file, find the line with "waf --run" command. You can replace any relative path where the waf is running, with absolute path of your "ns-3.27" folder. Once, you do that both Ardupilot component and ns-3 component should run together from the FlyNetSim.py script.
Regarding log file, check the REDME again for --help. The help shows -v option for different level of verbosity to include different information in the log file.

Hi @saburhb
thanks for your last suggestions, I tried to replace my absolute path however the problem still unsolved. here is the absolute path I have changed,

In addition, when I ran the FlyNetSim_direct_no_ns3.py everything works except the "disconnect" button. is it a common issue or not?

I am looking for further suggestions!
Much Appreciated

I have the exact same error. Been trying to fix zmq_sendmsg and found myself with this one too after installing other versions of czmq and zmq
