Hi,
according to https://en.wikipedia.org/wiki/Error_function, the erf()
function is part of the C++11 standard. It's already implemented in
math.h and accessible after
#include <math.h>
but for some reason, erf() and erfc() are not contained in cmath. Is this a bug?

I assumed if you're trying to use C++11 functions you'd be using -std=c++11
