Trying to compile testoutlook.prg in the \fwh\samples\outlook folder using xBuilder/xHarbour and getting unresolved externals on the following files:

xLINK: error: Unresolved external symbol '_HB_FUN_HB_DEFAULT referenced from (outlookmail.obj)'.
xLINK: error: Unresolved external symbol '_HB_FUN_HB_VFEXISTS referenced from (testoutlook.obj)'.
xLINK: error: Unresolved external symbol '_HB_FUN_HB_VFERASE referenced from (testoutlook.obj)'.
xLINK: error: Unresolved external symbol '_HB_FUN_HB_MEMOREAD referenced from (testoutlook.obj)'.

What library do I need to link in order to resolve this?

Thanks,
Randal

xhb.lib

I tried using xhb.lib from the 3/2025 version of xHarbour. Is there a later version of this lib I should be using?

Thanks,
Randal

Good afternoon, if I remember correctly, these commands are from HARBOUR, look for the equivalents in XHARBOUR.

Buenas tardes, si no recuerdo mal estos comandos son de HARBOUR, buscad los equivalentes en XHARBOUR.

Or show what you intend to do.

O muestra lo que pretendes hacer.

Gracias, tks.

Regards, saludos.

Example:

Code: Select all | Expand

// hb_default.prg

FUNCTION hb_Default( xVar, xValue )

  IF ValType( xVar ) == NIL
  
       xVar := xValue
     
  ENDIF
  
RETURN xVar

Or,

Code: Select all | Expand

FUNCTION hb_Default( xVar, xValue )
 	 
   IF ValType( xVar ) != ValType( xValue )
      xVar := xValue
   ENDIF
   
RETURN NIL

Regards, saludos.
