2. add execute right chmod +x /data/local/tmp/iperf3
3. execute with /data/local/tmp/iperf3 -s

results:

This is strange. In my device (different architecture) iperf3.19.1 starts ok. Also, I didn't make any change to the build environment, so I am not sure what can cause such problem. Few questions that may help the problem evaluation:

1. Did you try loading 3.18 again and it work ok?
2. What is the Android version you are using?
3. Can you think on anyway to get more information about the problem?
