C++ Templates+friends+operator overloading

Trying to overload << operator in templated class...this describes what happens and the solution along with explanation:
http://www.parashift.com/c++-faq-lite/templates.html#faq-35.16

Now what I don't understand is this :

"When you call the operator+ or operator<< functions, this assumption causes the compiler to generate a call to the non-template functions, but the linker will give you an "undefined external" error because you never actually defined those non-template functions."

Isn't this true for other functions as well? Like member functions? Why don't they generate a linker error?

The C++ Faq isn't the best place to search for answers. Try to consult your C++ Book, or the C++ FQA instead.

I have c++ primer and it does not answer the question.

no idea why it does it but you just have to do another template decleration right above the function using a different letter from what you used for your class

weird yes but sepples

bullshit

template<class T>
class fuck{

template<class P>
friend fuck(I forget if this needs one (>.<) KAWAIII!!!! ) operator +(fuck<P>)

<n00p> Zhivago: Because the stakeholders come up with requests and requirements. The stakeholder's requests are used to determine features
<Zhivago> n00p: Who were these stakeholders when they were inventing C?
<n00p> Zhivago: I don't actually know the answer to that question. Programmers for Unix?
<Zhivago> n00p: At some point some guy sat down and snorted a whole bunch of cocaine and came up with C's type syntax.
<Zhivago> n00p: What stakeholder issue drove that?

This except substitute ``C++templates'' for ``C type syntax''.

n00p is an annoying little turd who wishes he knew his lips from Zhivago's asshole

Zhivago is the most informative person ever. There is nothing Zhivago cannot explain.
