[R] R package with Fortran module on Windows? undefined reference to `__stack_chk_fail'

[Ignacio Martinez]

Hi,

I created a R library that uses a Fortran module. Everything works like a
charm on linux.

Now I'm trying to make it work on Windows. I cloned my git repository
<https://github.com/ignacio82/MyPi> on a windows computer, and when I press
the build and reload button on Rstudio I get these errors:

==> Rcmd.exe INSTALL --no-multiarch --with-keep.source MyPi

This is  the Fortran code:


Module Fortranpi
IMPLICIT NONE
contains
subroutine dboard(darts, dartsscore)
  integer, intent(in)                    :: darts
  double precision, intent(out)          :: dartsscore
  double precision                       :: x_coord, y_coord
  integer                                :: score, n

score = 0
do n = 1, darts
  call random_number(x_coord)
  call random_number(y_coord)

  if ((x_coord**2 + y_coord**2) <= 1.0d0) then
  score = score + 1
  end if
end do

dartsscore = 4.0d0*score/darts

end subroutine dboard

subroutine pi(avepi, DARTS, ROUNDS) bind(C, name="pi_")
  use, intrinsic                         :: iso_c_binding, only :
c_double, c_int
  real(c_double), intent(out)            ::  avepi
  integer(c_int), intent(in)             ::  DARTS, ROUNDS
  integer                                ::  MASTER, rank, i, n
  integer, allocatable                   ::  seed(:)
  double precision                       ::  pi_est, homepi, pirecv, pisum
! we set it to zero in the sequential run
rank = 0! initialize the random number generator! we make sure the
seed is different for each task
call random_seed()
call random_seed(size = n)
allocate(seed(n))
seed = 12 + rank*11
call random_seed(put=seed(1:n))
deallocate(seed)

avepi = 0
do i = 0, ROUNDS-1
  call dboard(darts, pi_est)
  ! calculate the average value of pi over all iterations
  avepi = ((avepi*i) + pi_est)/(i + 1)
end do
end subroutine pi

end module Fortranpi


I tried adding <http://i.stack.imgur.com/lC82X.png> -fno-stack-protector
-lssp but it did not help.

I also tried doing this "by hand" <http://i.stack.imgur.com/WY4VD.png> and
I get these errors:


> system("R CMD SHLIB -fno-stack-protector -lssp ./src/Fpi.f90")

Thanks for the help!
