R help - Jun 2000 - Building DLL file from fortran

Hi!
I made a DLL from fortran source code using MAKE command
(I am working with R 1.0.0 under windows 98). But when I tried
to call the wrapper function from inside R, it gave me the
following error message:
could anybody advise me?

RGUI caused an invalid page fault in
module RAINFALL.DLL at 015f:0619110e.

  Without more details (compiler and source used to build RAINFALL.DLL)
  it is difficult to give help.
  Some things to check:
  1) has the dll built using the C method to pass arguments on the stack?
  2) does your entrypoint in the dll agree with your wrapper on the
     type of the arguments passed (e.g., I almost always forget to
     coerce to integer the integer arguments).
  3) do the routines in RAINFALL.DLL work? The error is inside
     RAINFALL.DLL and until the .C or .Fortran call return R has
     no control on it (maybe in the future we will wrap this calls
     inside an exception handler so that and error in a packages
     dll will not result in the death of the entire process).
