[Rd] Re: [R] Fortran 95 in R ?

[Prof Brian Ripley]

First you need a functional F95 compiler.  I believe `g95' is obselete, 
replaced by gfortran.  For how to use that, please do read the R-admin 
manual in R 2.1.0 -- it can be done if you use a bug-fixed version of 
gfortran (post gcc-4.0.0) or a workaround.  Reliable F95 compilers such as 
those on Solaris have been usable with R for several years.

Please do remember to mention your platform and which compilers you used: 
see the posting guide.  Preferably also use the list it suggests (moved 
there).

Is it possible to run Fortran 95 code from R? I don't think so, but
hopefully someone can prove me wrong.
Here is the test I tried:
A little fortran 95 subroutine:
subroutine allloc()
real, dimension(:, :), allocatable :: a
integer :: n
n = 10
allocate(a(n,n+1))
end
I then compiled:
g95 -c allloc.f
R CMD SHLIB allloc.o
Here is what happens when I try to dyn.load it in R 2.1.0
dyn.load("allloc.so")
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library '/home/jbremson/dev/f_code/allloc.so':
/home/jbremson/dev/f_code/allloc.so: undefined symbol: _g95_filename
Is there any way to deal with this?
Is it somehow possible to reach the fortran 95 through C and avoid this
whole problem?
