C compilation problems with iperf3 - c++

Question

I am trying to compile the source code for iperf3 on an AIX machine and ran into some compilation problem and thought that you might save me!
So, when i run the configure script I get this output

And then the compiling fails, I have never seen this kind of compilation error and the configure.log doesn't say anything relevant
EDIT:
in the config.log file this is found
configure:16270: $? = 0

Configuration does not finish it jobs, because some libraries are not found. Install all required libs!
– LPs
The configure script insists on having floor(). Without this you cannot start compilation. … For your case the configure.log shows library libm not found.
