Using atan2 on the cRIO

If I use std::atan2 or atan2f, or even just try atan, the same error occurs. I've also tried using <math.h> instead of <cmath>. All compile, but none are defined. Does the cRIO not have trig functions in its c++ library, or am I doing something wrong?

I think the problem is not the header you are including, but the library that is not loaded. It is possible that the function is not compiled in, but that would surprise me a bit. Perhaps there is a separate library that needs to be loaded.
