Dear mac folks, I have started porting a large legacy toolset maintained in windows and heavily mpi laden so it can be used across platforms in R... so I am building a package out of it. On this note, I am noticing that almost all of the mpi dependent packages do not compile on the CRAN repositories.... with the basic issue that it appears it can not find mpi installed: configure: error:

Hi everybody, I'm trying to develop an R package with Fortran and OpenMP. I wrote a simple hello world but I'm not able to set the number of threads. I found this old email chain <http://r.789695.n4.nabble.com/Set-the-number-of-threads-using-openmp-with-C-td2284685.html> and I tried to set my compile instructions accordingly but i had no luck. *This is my makevars:*

I was able to make some progress by using this <https://github.com/bert9bert/ParallelForest/blob/master/src/Makevars> as a reference.

...or C++ compiler rather than the Fortran 9x compiler. This is consistent with fixed-form Fortran code and allows mixing of C++ and free-form Fortran on most platforms. Consequentially, a package which includes free-form Fortran 9x code which uses OpenMP should include SHLIB_OPENMP_CFLAGS (or the CXXFLAGS version if they also include C++ code) in PKG_LIBS rather than SHLIB_OPENMP_FCFLAGS - fortunately on almost all current platforms they are the same flag. * Macro PKG_FFLAGS will be used for the compilation of both fixed-form and free-form Fortran code...
