Inheriting from templated classes

ekaj · 2000-06-26T11:26:31

Hi, I''m having some trouble with my templated base class. I can compile the code, but when I try to link, i get unresolved externals for every member function in the base class. I have the member functions defined outside of the class declaration, but when I define the functions inside the class, there''s no linking errors. I''m using VC++ 6.0. Even when I double click on the member function in the class view, I get an error saying it can''t find the definitions either. I''ve made sure the .cpp file is part of the project as well. I''m really stuck as i don''t want to define the functions in the class, as they''re kinda large. Any help would be appreciated. Thanks. ekaj

I know extern is a supported keyword, I don''t think it has any relevance to the template implementation issue above, however. (Except the Microsoft specific option to suppress instantiation of individual functions, but that wasn''t the issue, was it?)

Lord Pi: Oops, I was confused with export. Apologies!

''export'' is a fairly new C++ keyword that isn''t supported by many compilers, because they don''t support the separation compilation model for templates. That''s what I wanted to say
