[Dev-C++] Undefined reference (maybe offtopic)

[<jto...@ut...>]

Hi,

I have a class template (let's say List <class T>) and other class which
inherits from first one(let's say company :public List <character *>. =
Just
to try I made a project with the first class and all went well (no =
memory
losses, no computer hanging, well, you know).=20
But when I made the project with the two classes , beginning the =
company.h
with #include "List.h" I have a lot of undefined link error. If I change =
the
include into #include "List.cpp" everything goes all right.

What may be wrong with my .h file?

Thanks in advance,
