@calfino
I have not seen this happening before. I can suggest you to try few things:

1. Remove the folder 'uav-net-sim' from "ns-3.27/build/scratch" folder
2. Move the folder 'uav-net-sim' from "ns-3.27/scratch" folder to your $HOME folder
3. Try running a sample code from "ns-3.27" directory , e.g.,
   ./waf --run scratch-simulator
   This should work fine without error
4. Then move back the 'uav-net-sim' folder to "ns-3.27/scratch" directory
5. Try running a uav-net-sim code from "ns-3.27" directory
   ./waf --run uav-net-sim

If you get the same error, you may need to try something else in the wscript file.

@saburhb I have tried with star.cc before, it stays the same. Now I try with scratch-simulator and it stays the same. I had this problem with 3 machines already 2 with ubuntu 16.04 and 1 using Linux mint 19.3

I have experimented the same problem and I have probed multiple solutions but without any result... it seems like the waf is not able to find the library in which the 'zmq_sendmsg' is, but I think that the paths are corrects. One week ago I have deployed the FlyNetSim in ubuntu 18.04 LTS and the part of NS-3 ran correctly, but now that I am deploying the project in ubuntu 16.04 LTS.

If anyone can show the version of the zmq packets or he/she knows about other solutions It will be helpful.

I also met same issue. my OS is ubuntu 22.04.
and I try to recompile https://github.com/zeromq/libzmq and
https://github.com/zeromq/czmq

It does not make sense.

I also try five steps mentioned by saburhb above, but it also does not make sence.

I think i have solved this issue.

I utilize zmq by this version libzmq-4.2.3.zip.

and i can run ./waf --run="uav-net-sim" in my ubuntu 22.04.
