Dear all,
I have next files: F1.h F1.c F2.h F2.c LinkDef.h
-----------------------------------------
// F1.h
#ifndef F1__include
#define F1__include
#include "TObject.h"
class F1 : public TObject
{
public:
F1(void) {}
ClassDef(F1,1)
};
#endif // F1__include
------------------------------------------
// F1.c
#include "F1.h"
ClassImp(F1)
------------------------------------------
// F2.h
#ifndef F2__include
#define F2__include
#include "TObject.h"
class F2 : public TObject
{
public:
UInt_t a;
F2(void) {}
ClassDef(F2,1)
};
#endif // F2__include
------------------------------------------
// F2.c
#include "F2.h"
ClassImp(F2)
------------------------------------------
// LinkDef.h
#ifdef __CINT__
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ class F1;
#pragma link C++ class F2;
#endif
-----------------------------------------
Very simple files.
Then i do:
=======================================================
rootcint -f F1_Cint.cxx -c F1.h LinkDef.h
rootcint -f F2_Cint.cxx -c F2.h LinkDef.h
g++ -O -fPIC -I /usr/local/root/include -c F1.c -o F1.o
g++ -O -fPIC -I /usr/local/root/include -c F2.c -o F2.o
g++ -O -fPIC -I /usr/local/root/include -c F1_Cint.cxx -o F1_Cint.o
g++ -O -fPIC -I /usr/local/root/include -c F2_Cint.cxx -o F2_Cint.o
g++ -O -shared F1.o F1_Cint.o -o ./F1.so
g++ -O -shared F2.o F2_Cint.o -o ./F2.so

Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] .L F1.so
root [1] printf("%d\n",sizeof(F1));
12
root [2] .L F2.so
root [3] printf("%d\n",sizeof(F2));
16
root [4] printf("%d\n",sizeof(F1));
0
=======================================================
Why after loading F2.so sizeof(F1)==0 ?
OS: Linux 2.1.76 and 2.0.32

Thanks in advance,
