Issue with Constrcutors with templates

Given below are is my cpp code.i have written both declaration and defunition in same cpp file because there are templates in this code and i got some errors when i had two seperate files for header and code.so i had to write everything in same file.Still, i have errors with constructor declaration and definition. Why is this throwing the below error, is there something which am missing.

template<class T>
class Linklist
{
public:
Linklist();
Linklist(Linklist<T> & a);
~Linklist();
}     
template<class T>
Linklist<T>::Linklist()
{
}
template<class T>
Linklist::Linklist(Linklist<T> & a) 
{
} 

Error C2244: 'Linklist::{ctor}' : unable to match function definition to an existing declaration definition 'Linklist::Linklist(Linklist &)' existing declarations 'Linklist::Linklist(Linklist &)' 'Linklist::Linklist(void)'
