 c2064 problem-- namespace issue??
Hello all,
Basic question. I have a vector/matrix class I'm building, and I seem
to be getting errors such as this:
..\otherFileUsingVectorMatrixClass.cpp(182) : error C2064: term does
not evaluate to a function
the specs are such:
vec3f.h:
Vec3f
{
...
public:
...
// calculate dot product
friend float dot( const Vec3f&, const Vec3f& );
};
-------------
vec3f.cpp:
float dot( const Vec3f &a, const Vec3f &b )
{ return a[0]*b[0] + ...; }
-------------
vecMatClass.h
#include "vec2f.h"
#include "vec3f.h"
#include "vec4f.h"
#include "mat3f.h"
#include "mat4f.h"
-------------
someOtherFileUsingVectorMatrixClass.cpp:
#include "vecMatClass.h"
void Class::foo()
{
Vec3f a( 2,3,4 ), b( 5,3,2 );
const float dotP = dot( a, b );
}
Am I missing something? I'm using MSVC++ 6 and its compiler. I tried
to look up namespaces and such, and saw really old posts saying the
compiler had trouble recognizing functions in namespaces, or something
along those lines.
For a large program, is it ok to "pollute" the global namespace with
such functions as dot() (and there are 3 versions of it, for Vec2f,
Vec3f, and Vec4f)?
Thank you,
Jon
