I'm the author of the UDUNITS packge and I've never built it on a
Windows system.
The file "udunits.inc.in" is not meant to be included by Fortran code.
The file is meant to be processed by the "configure" script to create
the file "udunits.inc", which IS meant to be included by Fortran code.
You will have to manually transform "udunits.inc.in" into "udunits.inc"
by replacing the string "@UD_POINTER@" with the Fortran type that is
appropriate for storing a pointer to a structure (e.g., "integer").
As for your unresolved symbol problem, do you know what Compaq Visual
Fortran is closest to in terms of its calling-conventions?
Silicon Graphics f77
IBM AIX FORTRAN
VAX VMS FORTRAN 5.4
Alpha VMS DEC FORTRAN
Alpha OSF DEC Fortran for OSF/1 AXP
Apollo f77
CRAY Fortran
NEC SX-4 Fortran
CONVEX Fortran
Sun Fortran
PowerStation Fortran
HP-UX Fortran
LynxOS f2c
VAXUltrix f77
UNIX f2c
NAG f90
Absoft UNIX F77
Absoft Pro Fortran
Portland Group Fortran
It is necessary to know this in order to tell the C compiler what
calling-conventions to following when compiling the C code that is the
Fortran interface to the UDUNITS library.
