Try R CMD SHLIB test.f If SHLIB know it has to deal with Fortran code, it adds the appropriate libraries.

I have the following Fortran code
subroutine sub(path)
character*100 path
open(10,file=path)
end
saved as test.f
which I compile with
g77 -c test.f
then I make the shared libary in R (Version 1.9.0) with
system("R CMD SHLIB test.o")
so far, everything OK.
But
dyn.load("test.so")
returns the following error message:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library "test.so":
test.so: undefined symbol: f_open
I get similar error messages with r/w Fortran instructions like
write(*,*) , read(*,*)
I used to use such programs on my computer under mandrake linux 10.
The problem reported occurs on a new server operating under
another linux distrib (debian).
Thanks in advance for any help,
Gilles

It works with R CMD SHLIB test.f Thanks.
