Linker errors with templates

[Generic Usenet Account]

I am "plugging in" a class type into an STL map definition and I am
getting linker errors unless all my class definitions are defined in
the header file, as opposed to a separate source file. This is
happening on the following C++ compiler:
gcc version 3.3.1

My question is whether this is standard behavior, or just a quirk of
the compiler that I am using.

Thanks

This issue is covered in Marshall Cline's C++ FAQ. See the topics
"[34.12] Why can't I separate the definition of my templates class
from it's declaration and put it inside a .cpp file?" and
"[34.13] How can I avoid linker errors with my template functions?".
It is always good to check the FAQ before posting. You can get the
