[R-pkg-devel] Fortran with OpenMP on MACOS
I'm, sorry but I don't understand your question. To my understanding, adding the mentioned MACROS should be enough to add the flag -fopenmp. Actually, when I build the package, gfortran already uses the flag -fopenmp: gfortran -fno-optimize-sibling-calls *-fopenmp* -fpic -g -O2 -fdebug-prefix-map=/build/r-base-8T8CYO/r-base-4.0.3=. -fstack-protector-strong -c get_threads.f90 -o get_threads.o Em ter., 13 de out. de 2020 ?s 12:41, Erin Hodgess <erinm.hodgess at gmail.com> escreveu:
I?m sure that you have done this, but did you set a compiler option of -fopenmp, please? Thanks On Tue, Oct 13, 2020 at 9:35 AM Sergio Ibarra-Espinosa < sergio.ibarra at usp.br> wrote:
Dear List, I have a package that was archived ( https://cran-archive.r-project.org/web/checks/2020/2020-10-07_check_results_vein.html ) because I could not solve an issue with OpenMP and Fortran on MACOS. I have seen that packages with C add precompilation conditions, for instance: https://github.com/tesujimath/R-OpenMPController/blob/86bd047e8bfdf3c87877336ff8e2d3b69327fe03/src/omp_set_num_threads_ptr.c#L12 #ifdef _OPENMP omp_set_num_threads(*np); #endif So, I tried adding those lines in #ifdef _OPENMP #endif in fortran, with the flag -cpp and the MACROS recommended by the R EXTS manual: USE_FC_TO_LINK = PKG_FFLAGS = $(SHLIB_OPENMP_FFLAGS) *-cpp* PKG_LIBS = $(SHLIB_OPENMP_FFLAGS) But with R CMD Check i got the message: Non-portable flags in variable 'PKG_FFLAGS': -cpp I would be very grateful if someone provides me some guidelines.
