How to get debug symbols for libiperf?

[dnb02]

I am trying to profile iperf3 data transmission using perf and analyzing using hotspot.
libiperf turns up with 92/97 debug symbols missing.

I have tried installing iperf3 debug symbols package.

➜  ~ sudo apt install libiperf0-dbgsym libiperf0 libiperf-dev

Edit: What if iperf3 is built from source? How do we get debug symbols for those?
