C++ error LNK2019 can not run code

Question

Dear developers c++, I the next problem: trying to compile my project i'm getting the "error LNK2019: unresolved external symbol" even though all of the declared methods in headers are defined in the .cpp

I attach my code together with the post. Thank you for any assistance!

p.s. the code is presented as VS2005 solution

the errors i get is next:

1>Wm5Vector3.obj : error LNK2019: unresolved external symbol "public: double const & __thiscall Wm5::Tuple::operatorconst " (??ATuple@Wm5@@QBEABNH@Z) referenced in function "public: __thiscall Wm5::Vector3::Vector3(class Wm5::Tuple const &)" (??0Vector3@Wm5@@QAE@ABVTuple@1@@Z)

Answer 1

To resolve the problems of the Wm5::Tuple::operator[] the solution is to put the functions in the header file. The linker does not like inline functions in a CPP.

And to resolve the problem of the Vector3 operator* (double scalar, const Vector3& vec); remove the inline from the header file and put the definition like:

inline Vector3 Wm5::operator* (double scalar, const Vector3& vec)

in the CPP file, since you also need to specify the namespace.
