Compiler errors mean the compiler could not translate the source code you provided into object code. It usually means you have a syntactic or semantic error in your own program that you have to resolve before your program exhibits the behavior you're intending it to have.
Linker errors mean the linker could not build an executable program from the object code you provided. It usually means your program does not properly interface with its own dependencies or with the outside world (e.g. External libraries).

Function in main should be like :
void (Bix::*ptr)()= &Bix::Myfunction;
void (Bix::*ptr)()= &Bix::Myfunction;

The linker error comes because the class is only declared and the definition is not there for the static member function. If we give a definition for member function then the linker error will be resolved by adding the following code.
void Bix::MyFunction()
{
std::cout << "I am a static function of Class Bix"
}
void Bix::MyFunction()
{
std::cout << "I am a static function of Class Bix"
}

Can anybody explains clearly why it reports linking error?

Linker error is coming because we have redefine static function outside the class.
void Bix::Myfunction(); // Will solve linker problem.
void Bix::Myfunction(); // Will solve linker problem.

What is linker error ? because on being compiled this program shows no error and no output.
