Subject: [OMPI users] Subject: Building openmpi-1.6.4 with 64-bit integers
From: H Hogreve (hogreve_at_[hidden])

 Dear mpi team / users:
 To get a mpi with 64-bit integers (linux system:
 ubuntu 12.04) I invoked the following
 configuration options:
 ./configure --prefix=/opt/openmpi CXX=icpc CC=icc F77=ifort FC=ifort
 The subsequent make/install scripts apparently
 went through smoothly, but when I check
 ompi_info -a | grep 'Fort integer size'
 the result reads:
 Fort integer size: 4
 What went awry?
 For all hints and suggestions many thanks in advance,
 Hans H.
