[aspectc-user] slices in separate header files

[Panu Bloigu]

Hello.

The ac++ 1.0pre3 change log says that slices can be implemented in 
separate header files. What does that mean exactly and what's the 
correct syntax for defining a class slice outside of an aspect header?

I have tried compiling the following files in Eclipse with the latest 
AspectC++ plugin.

=======================================================
// File: Slice.h

#ifndef SLICE_H_
#define SLICE_H_

class Slice
{
public:
        Slice();
        virtual ~Slice();
        void method(){}

        //class Inner{};
};

#endif /*SLICE_H_*/
=======================================================

=======================================================
// File: TargetClass.h

#ifndef TARGETCLASS_H_
#define TARGETCLASS_H_
class TargetClass{};
#endif /*TARGETCLASS_H_*/
=======================================================

=======================================================
// File: AnAspect.ah

#ifndef ANASPECT_AH_
#define ANASPECT_AH_
#include "Slice.h"
aspect AnAspect
{
        advice "TargetClass" : slice class Slice;
};
#endif /*ANASPECT_AH_*/
=======================================================

=======================================================
// File: main.cpp

#include "TargetClass.h"
int main()
{
        TargetClass tg;
        return 0;
}
=======================================================


Now the complier produces the following output at the maximum verbosity 
level:

As you can see there are no error messages printed, only this: "[main.o] 
error 1". Could someone please shed some light on this? How do go about 
defining slices in separate header files?


Thanks,
