Hello Jose,

Somehow this is the reason (I don't know yet exactly the details, but the
problem is in the includes ("#include 'hbvmpub.h'") on the final C code
obtained from the prg).
So, for the moment, please use a separate C file to contain the HB_FUNC():
/---------------- start C code --------------------/
#include "hbvmopt.h"
#include "hbstack.h"
HB_FUNC( __GETMESSAGE2 )
{
hb_retc(hb_stackItem(hb_stackBaseItem()->item.asSymbol.stackstate->lBaseItem
)->item.asSymbol.value->szName);
}
/---------------- end C code --------------------/
this will compile fine .

Check the C program obtained from the compiled prg code and check what does
the include files in it to see the problem.
