[R] first steps to build a FORTRAN DLL used by R
Hi, I am a fortran developper, freelance, hired by a huge company to transform R calculations to FORTRAN. I am discovering R. Few years ago someone built FORTRAN dll using Lahey Fortran (perhaps only to test his programs) and gfortran. I found two .bat files, one for Lahey : ECHO compilation fortran LAHEY regression\regr.f lf95 -dll -ml msvc regr.f >regr.txt type regr.txt and one for gfortran : ECHO creation DLL FORTRAN par R regression\regr.f C:\utilitaires\R\R-3.1.0\bin\i386\rcmd SHLIB regr.f >creationdllr.txt TYPE creationdllr.txt Creationdllr.txt being : gfortran -m32 -O3 -mtune=core2 -c regr.f -o regr.o gcc -m32 -shared -s -static-libgcc -o regr.dll tmp.def regr.o -Ld:/RCompile/CRANpkg/extralibs64/local/lib/i386 -Ld:/RCompile/CRANpkg/extralibs64/local/lib -lgfortran -LC:/utilitaires/R/R-3.1.0/bin/i386 -lR Nowadays, the company uses Intel's FORTRAN. I could build a dll with it but R doesn't want to load it ! parameters are : 'keep fortran 77 compatibility' and 'console mode'. What I would like to know are 'the first steps' or 'building FORTRAN dll's for beginners (dummy ?)' : 1) Can we use Intel's Fortran or must we use gfortran 2) If we must use gfortran is it given with R ? 3) If we can use Intel's Fortran, what are the parameters to use and has someone recommandations to give ?
