Okay, so this is really werid. I've never encountered anything like this.
Part of my program (Fails to compile) contains three namespaces as following:
// namespaceA.h
namespace A {
enum Kind { jimmy, david };
}
// end of namespaceA.h
// namespaceB.h
#include "namespaceA.h"
namespace B {
class Tree {
public:
Tree *prev;
Tree *next;
Tree *down;
A::Kind kind;
Tree();
~Tree();
};
}
// end of namespaceB.h
// Implementation details of the class are placed in namespaceB.cc
// Constructor / Desctructor defined in the namespaceB.cc file!
// Something like this,
#include "namespaceB.h"
namespace B {
inline Tree::Tree() { ... }
inline Tree::~Tree() { ... }
}
// namespaceC.cc
#include "namespace.B"
namespace C {
void run() {
B::Tree *tree; // FINE
B::Tree tree; // Fail to compile!?
}
}
// end of namespaceC.cc
Now, g++ went along just fine but the linker ld complains:
"namespaceC.cc: undefined reference to `B::Tree::Tree()'
"namespaceC.cc: undefined reference to `B::Tree::~Tree()'
I have never ever encountered anything like this before... This just seems really weird, I don't even know any words/terms to describe this problem.
I would much appreciate any help.
Thanks,
