[petsc-users] multiple definition of `main' with intel compilers

[Alfredo Jaramillo]

hello Satish, no the tests seem to be ok altough some error related to mpd.

==============THE TESTS===================

Running check examples to verify correct installation
Using PETSC_DIR=/scratch/simulreserv/softwares/petsc-3.13.0 and
PETSC_ARCH=x64-O3-3.13-intel2016-64
Possible error running C/C++ src/snes/tutorials/ex19 with 1 MPI process
See http://www.mcs.anl.gov/petsc/documentation/faq.html
mpiexec_sdumont11: cannot connect to local mpd
(/tmp/mpd2.console_alfredo.jaramillo); possible causes:
  1. no mpd is running on this host
  2. an mpd is running but was started without a "console" (-n option)
Possible error running C/C++ src/snes/tutorials/ex19 with 2 MPI processes
See http://www.mcs.anl.gov/petsc/documentation/faq.html

Completed test examples

===============================

I entered in src/snes/tutorials/ and executed "make ex5f". The binary exf5
was created
