Question

How do i make a makefile for 2 template classes in c++ ?

for example i have

template <class T>
class item

{

     private:

         T value

     // other code

};

and

template <class T>

class drive

{

       private:

              item<T>* node;

        //more code

};

            

Answer 1

You should not compile the template files. Template definitions are commonly placed in header files. Therefore, you can save these two template into two separate header files files, named item.h and drive.h.

Include these header files in the main.cpp.

Then write a Makefile:

main.o: main.cpp item.h drive.h
g++ -c -o main.o main.cpp

N.B:  The header files do not require any special extension conveying that they contain templates, although you could give them one, such as .t, if you prefer. The preprocessor will include any file specified in a #include regardless of its name.
