    DLL and GCC

    I think this is a basic question...
    Could anyone tell me please, how to import DLLs using GCC?

    I'm using Dev C++...

    This one keep failing...

    Code:
    #define IMPORT __declspec (dllimport)
    
    template<typename T>class IMPORT TestClass {
    public:
      T add(T a, T b);
    };
    
    int main() {
      TestClass<int> test;
      test.add(10, 20);
    };
    Code:
      [Linker error] undefined reference to `TestClass<int>::add(int, int)'
    Thanks in advance.
    Just GET it OFF out my mind!!

    I don't know if I've quite got a hold of what you're asking, but if your DLL has a definition of a template function in it, that's not going to do you any good, since a template definition doesn't compile into anything and g++ doesn't support export yet.
