Alessandra,

your configure command line is

./configure CC=gcc CXX=gcpc F77=gfortran FC=gfortran --prefix=/usr/local


i guess gcpc is a typo and you meant g++ instead.

fwiw, the default prefix is /usr/local, so you do not really need '--prefix=/usr/local'


Cheers,


Gilles

Goodmorning,
I'm facing a problem during the installation of Open MPI.
The error appears on terminal at a certain point during the compilation and is the following:

*** C++ compiler and preprocessor
checking whether we are using the GNU C++ compiler... no
checking whether gcpc accepts -g... no
checking dependency style of gcpc... none
checking how to run the C++ preprocessor... /lib/cpp
configure: error: in `/Users/Alessandra/Desktop/openmpi-2.0.2':
configure: error: C++ preprocessor "/lib/cpp" fails sanity check

but GCC is installed on my MacBook. My OS is OS X El Capitan (10.11.6).

I hope you can help me, thank you for your time!
Best regards,
Alessandra Bonazzi
