When I try to make the program I am getting an error with the gettimeofday function even though in ./configure it claims that it found the function.

any ideas on what to do to fix these errors?

Notice:
checking sys/time.h usability... yes
checking sys/time.h presence... yes
checking for sys/time.h... yes
Then if it says:
error: 'gettimeofday' was not declared in this scope
then obviously something is wrong in the headers of the library itself, i.e. sys/time.h is simply not included properly. Going to <iperf-dir>/include/headers.h and skimming through it quickly reveals that sys/time.h is not included when we are on Windows, i.e. in the #ifdef WIN32 block, while for Unix block (in #else) it is indeed included. As a result, all you have to do is to add:
#include <sys/time.h>
to <iperf-dir>/include/headers.h for example on line #91.
Although this will solve your current problem, you will later hit some uncompilable code (i.e. written with mistakes) during compilation and still fail. Furthermore, frankly speaking, the library is terribly designed in terms of Windows portability. The code looks quite ancient and ugly, so it's no surprise that it does not compile. You might have more luck with iperf 3 as they might have improved the quality of the library and its portability issues.
