Dear R Developers,
For package seriation I use Fortran code. I recently got a request to add
#if defined(__ICC) || defined(__INTEL_COMPILER)
USE IFPORT
#endif
to the code since the Intel Fortran compiler otherwise has problems with
rand(). However, to enable the FPP preprocessor I have to either add a
compiler flag (-cpp for gFortran) which is possibly not portable or
change the extension to .F, .fpp, .FPP (and a few others) which
automatically invokes the preprocessor (hopefully on all platforms). I
tried .fpp and added the following to Makevars:
OBJECTS=arsa.o bburcg.o bbwrcg.o bea.o criterion.o dist.o fprintf.o
greedy.o optimal.o stress.o
%.o: %.fpp
$(F77) $(ALL_FFLAGS) -c $< -o $@
It seems to work (I tried Linux and Windows) but R CMD check gives me:
* checking if this is a source package ... WARNING
Subdirectory ‘src’ contains:
arsa.fpp bburcg.fpp
Is there a different preferred method to do this? Is it possible to add
support for Fortran with the fpp preprocessor (.fpp files) to the R
package building process?
Thanks,
Michael
