[R-sig-hpc] Problems Installing Rmpi

[Hao Yu]

Can you change configure.ac with
###################################
AC_INIT(DESCRIPTION)

AC_PROG_CC

AC_ARG_WITH(mpi,
[   --with-mpi=/opt/lib32/usr/lib          Location of MPI library.],
[   if test "${withval}" != no; then
        MPI_ROOT=${withval}
        MPI_INCLUDE="-I${MPI_ROOT}/include"
        LDFLAGS="$LDFLAGS -L${withval}/lib"
        CFLAGS="$CFLAGS -I${withval}/include"
    fi  ]
)
MPITYPE="OPENMPI"
MPI_DEPS="-DMPI2"
AC_CHECK_LIB(util, openpty, [ MPI_LIBS="$MPI_LIBS -lutil" ])
AC_CHECK_LIB(pthread, main, [ MPI_LIBS="$MPI_LIBS -lpthread" ])

PKG_LIBS="${MPI_LIBS} -fPIC"
PKG_CPPFLAGS="${MPI_INCLUDE} ${MPI_DEPS} -D${MPITYPE} -fPIC"

AC_SUBST(PKG_LIBS)
AC_SUBST(PKG_CPPFLAGS)
AC_SUBST(DEFS)

AC_OUTPUT(src/Makevars)

Then, run "autoconf" to generate a new "configure" file. Use build to
build a new tgz file and install again.

If you look the original configure.ac, there is no place where mpi.h is
appended to ${MPI_INCLUDE}. I don't know why the OS does such a way.
