Error C2676 binary '<<': 'std::ostream' does not define this operator or a conversion to...

I don't understand the compilation error C2676
for the below code
#ifndef __VEC_3D_H__
#define __VEC_3D_H__
#include <vector>
#include <cmath>
namespace Internal
{
/** very simple 3D vector/ point */
class Vec3D
{
public:
float mX;
float mY;
float mZ;
/// null constructor
Vec3D(void) {}
/// construct from data
Vec3D(float x, float y, float z) : mX(x), mY(y), mZ(z) {}
inline friend std::ostream& operator<< (std::ostream& os, const Vec3D& v)
{
os << "(" << v.mX << ", " << v.mY << ", " << v.mZ << ")";
return os;
}
};
}
#endif
I have put a functionally identical code in another class and it compiles and runs fine. What is wrong here?
EDIT1: corrected BOBVec3d to Vec3D, was a typo
EDIT2: removed using namespace Internal;, it is indeed point-defeating to have it in a header file

On a tangential note, all identifiers that conrain two underscores in a row, and all identifiers that start with an underscore and a capital letter, are reserved. Defining such identifiers in your own code is UB.

I apologize. I actually use Resharper myself, but many people prefer to use VAX (for performance reasons on large projects, although I have had no issues), so thought I'd mention it as well. I checked your code with Resharper and it did seem to pick it up. Here's a picture.
