Subject: [Dev-C++] classes help


Does anyone know how to link an implementation file (ie: Myclass.C) with a
client code (ie: usingClasses.C) so they can use my own Myclass.h header
file?
This is weird, I tried doing it in a G++ compiler on a solaris unix terminal
at school and it worked. However, the same exact code didn't work in
Dev-cpp. I know there are other options like console application or empty
project and I don't know how to use those.
Please let me know the correct way to link an implementation and a client
code so they can use my own defined class.

Thank you very much.

Greets, Santiago.

This is the general layout I use:

Interface file, only declarations: class.h
Implementation file, only definitions: class.cpp
Client file(s) that use the class: test.cpp

<class.h>

// Prevent re-entry
#ifndef __CLASS_H
#define __CLASS_H

#include <what_foo_needs.h>

class foo
{
    public:
        foo();
        foo(int);
        foo(int, int);
        ~foo();

    protected:
        int    apples;
        int    oranges;
};

#endif // __CLASS_H

</class.h>

Note that the interface file has *no* implmentation whatsoever. It's
allegedly a good practise to keep them separate.

class.cpp will have the definitions, including the constructors and
destructors. It will include class.h.

The client files will #include class.h, and are then finally linked with
class.cpp (by adding class.cpp to the project/makefile/command-line.

You say that the code worked on Solaris, was it on GCC? If so, it should
work here also. Maybe the problem is syntactic (mismatched braces, missing
semicolon, etc.).

PS: Note that this is what I do. If you have any better ideas, let us know.
