Initializing a static const member array of a class type

[Steven T. Hatton]

Is there a way to initialize an member array of user defined objects that is
declared static const?

For example:

const vec3f I(1,0,0);
const vec3f j(0,1,0);

class corner_functor
{
public:
corner_functor( );

~corner_functor ();
static const Vec3f dir[5] = {-I, J, I, -J, -I};//This doesn't work
private:
int index;

};
I also tried some variations of this:

const SbVec3f* corner_functor: :dir =
{
-I, J, I, -J, -I
};

Only const int, long, short, char, bool, and integral constants in general
can be initialized in the class. Try,

class corner_functor
{
...
static const Vec3f dir[5];
};
const Vec3f corner_functor: :dir[5] = {-I, J, I, -J, -I};

The above line should occur in the cpp file. You can also define I and J in
the same cpp file.
Note that the following is undefined in ANSI C++

// header.h
extern const Vec3f I;
extern const Vec3f J;

// functor.h
defines class corner_functor;

// functor.cpp
#include "header.h"
const Vec3f corner_functor: :dir[5] = {-I, J, I, -J, -I};
