Thank you for the help.
yes. Though, as Brian mentions below it's strange that you
can't compile the package (how?) with the file present.
I'd guess that this would mean you cannot (easily) install any
CRAN packages that use C++ ?
I think this will preclude you from using very fine R extensions!
My g++ compiler can't handle the -lgfortran switch, while gcc can. I
think it is the fault of my Linux distribution (http://nixos.org), but
it was an easier solution to use gcc instead of g++ than fixing g++.
This probably means that I can't compile any R packages using C++ and
fortran at the same time. I will investigate further in this error.
Yes, there is no guarantee that you can mix any two languages except C
and Fortran.
But this is not the way a Linux system is usually set up, and you may
be able to resolve it by including the path to libgfortran in
LD_LIBRARY_PATH, or editing FLIBS in R_HOME/etc/Makeconf to be
something like
"-L /path/to/gfortran -rpath=/path/to/gfortran -lgfortran"
This was the error:
