Programming :: C++ - Initializing Static Member Array?

The code below defines an array of structures in a class. I would like this to be a Static array and then initialize the array in a initialization method. I understand that initialization lists are the way to go but due to the size and complexity of the array I plan on using (the example below is a simple snippet that illustrates the problem) I would like to use the initialization method. However, I cant even get this thing to compile. The error says the reference to the ArrayOfStructs in the initialization routine is undefined.

P.S. This is the error message

undefined reference to `ClassWithStaticArray::ArrayOfStruts'

class ClassWithStaticArray {
public:
struct IntegerStruct
{
