I am installing Open MPI on my Amazon EC2 server. After I installed the latest gcc-7.3 compiler, I tried to install openmpi-3.0.1 from their official website.

Here is the code that I've typed in: 

wget "https://www.open-mpi.org/software/ompi/v3.0/downloads/openmpi-3.0.1.tar.gz" 
tar -xvf openmpi-3.0.1.tar.gz
cd openmpi-3.0.1
./configure --prefix="/home/ubuntu/.openmpi"

following the instruction guide here http://lsi.ugr.es/jmantas/pdp/ayuda/datos/instalaciones/Install_OpenMPI_en.pdf

The result says C and C++ compiler not link compatible (see the picture) enter image description here

Problem revised. First, following @Gilles Gouaillardet's thought, if I type dpkg --list | grep compiler, it shows

Second, here is the config.log following @Zulan's suggestion 

 It was created by Open MPI configure 3.0.1, which was
 generated by GNU Autoconf 2.69.  Invocation command line was

If you want to use GNU 7 compilers, you first have to install g++-7, and then tell Open MPI to use them

./configure --prefix=/home/ubuntu/.openmpi CC=gcc-7 CXX=g++-7 FC=gfortran-7

  • Got you! Thanks – Woodpecker Wang Apr 26 '18 at 02:45
  • `./configure ... CC=gcc-7 CXX=g++-7 FC=gfortran-7` ?? If the latter, result is `configure: WARNING: you should use --build, --host, --target checking for perl... perl ============================================================================ == Configuring Open MPI ============================================================================ *** Startup tests checking build system type... Invalid configuration `...': machine `...' not recognized configure: error: /bin/bash config/config.sub ... failed` – Woodpecker Wang Apr 26 '18 at 03:00
  • did you replace `...` with your configure options ? – Gilles Gouaillardet Apr 26 '18 at 04:01
  • check my edited version. note it is not wise to install Open MPI in `$HOME/.openmpi` since this directory is used to store per user configuration. – Gilles Gouaillardet Apr 26 '18 at 06:14
