"export" is not supported by most existing compilers, g++
included. All your template code must be visible on the instantiation
point. This is achieved by either

1. Putting all template code on header files and #include them on the
   .cpp file where you want to use that templates.

2. Putting all template definitions (the sort of thing you have on
   your .cpp file) on a file and #include that file at the end of the
   header that declares the templates.

On some contexts, you can explicitly instantiate the templates you
need, but this is not a good thing on the general case.
