mpi.h errors on Mavericks packages

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: "Cannot find mpi.h header file"

I do not see any chatter about mpi issues in the lists since the
inception of mavericks.. and possibly this question should go to
Simon.. but in case I missed a discussion, or if anyone has any
suggestions on how to proceed, or what might be missing from the Rmpi,
npRmpi, etc. packages for compilation on Mavericks, it would be
greatly appreciated if you could let me know.. and maybe I can help
fix the other packages as well.

Thanks for any help or pointers to guide me!

Hi Dan -- not a mac folk, or particularly expert on the subject, but have you 
looked at section 1.2.1.1 of RShowDoc("R-exts")? The basic idea is

a) check for compiler support via a src/Makevars file that might be like

PKG_CFLAGS = $(SHLIB_OPENMP_CFLAGS)
PKG_LIBS = $(SHLIB_OPENMP_CFLAGS)

b) conditionally include mpi header files and execute mpi code with

#ifdef SUPPORT_OPENMP
#include <mpi.h>
#endif

and similarly for #pragma's and other mpi-isms littered through your code? 
Likely this gets quite tedious for projects making extensive use of openMP.

sorry for the noise! you're after mpi and not openMP. Arrgh Martin

Apple has removed MPI from recent OS X versions so it is not available there.

So currently, you have to install whatever MPI implementation you prefer from sources since neither the libraries nor the toolchain are available. What Apple used to ship was OpenMPI which still exists, but to my best knowledge there is no official, maintained binary for OS X so on Mavericks we have nothing to build CRAN binaries against, so you have to install everything from sources.

Cheers,
