Hi
I've built a dll using Fortran code and can call it by either R or
Fortran. Calling by the former gives me the wrong answer and the later
gives the correct answer. From what I've read, it looks like I should use
the subroutines DBLEPR, INTPR and REALPR to get values to show up in R
which I hope will allow me to find the error. I've downloaded the
R-2.12.0.tar.gz but have been unable to find these subroutines or any
examples of how to get Fortran to recognize them. Obviously when I try to
compile I get undefined reference to 'dblepr_'. So I was wondering if
there is some way I can specify in the makefile or possibly by building
the dll using R CMD SHLIB where to find these subroutines or where else
this information might need to be. I noticed in Venables book that the
functionality of these subroutines can be compiler dependent but there is
no specification of which compilers might work. I'm using gfortran could
this be an issue?
Thanks,
