Unsuccessful OpenMPI configuration

[Jakub_S_1]

Dear Community,

Could you please help me out with the following issue:

1. I have installed Intel Package and source compilers (i.e. icc compiler) in my system:   /opt/intel/compilers_and_libraries_2017.4.196/linux/bin/intel64/icc

2. I try to run ./configure with flags:   $ ./configure --prefix=/usr/local CC=icc CXX=icpc F77=ifort FC=ifort

3. Finally the system says that there is no icc existed, but it is recognizable from which icc command.

Please tell me what I do wrong...

I paste small part of the output log from OpenMPI configuration and also send the whole file in the attachment.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by Open MPI configure 1.10.7, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ ./configure --prefix=/usr/local CC=icc CXX=icpc F77=ifort FC=ifort

Hi there,

Problem solved. I used sudo along with ./configure so the system tried to use default root compilers as they weren't configured the error appeared. Just get rid of sudo, and then OpenMPI installer will look for compilers configured in the user profile.

Apparently, you didn't source the compilervars.sh script in your Intel compiler installation under sudo so as to be able to run them as root.  As you figured out, it's normal to build openmpi as a plain user, then sudo install (never running the compilers as root).
