Summary: Forward referencing problem

Initial Comment:
Here some simple .cxx and .h files are given.

base.cxx
-------
#include <stdio.h>
#include "base.h"

mybase :: mybase()
{
}

mybase :: ~mybase()
{
}


base.h
------
#ifndef _H_BASE
#define _H_BASE

class mybase
{
    public:
        mybase();
        virtual ~mybase();
};

#endif



derived.cxx
---------
#include <stdio.h>
#include "derived.h"

myderived :: myderived() : mybase()
{
    printf("Hello\n");
}



derived.h
--------
#ifndef _H_DERIVED
#define _H_DERIVED

#include <stdio.h>
#include "base.h"

class myderived : public mybase
{
    public:
        myderived();
        virtual ~myderived() { ; }
};

#endif




Makefile:
-------
CC = d\:/Mingw/bin/gcc.exe
LD = d\:/Mingw/bin/ld.exe
INCLUDE = -I.
LIB = mylib.a
OBJ = base.o derived.o
CFLAGS = -g

$(LIB) : $(OBJ)
    $(LD) -r -o $(LIB) $(OBJ)

%.o : %.cxx
    $(CC) $(CFLAGS) -o $@ -c $<

clean :
    \rm -rf *.o $(LIB) $(BIN)




While building mylib.a, mingw-ld reports an error:
derived.cxx:7: reloc refers to symbol
`text$__tf6mybase' which is not being output

But if we write in Makefile
OBJ = derived.o base.o, 
ld doesn't report any error.

The problem of reloc arises due to the option -g.

Is there any way to get rid of this problem?
