- Subject: using openMPI on OS X 10.5
I am using gcc version 4.0.1 on a MacPro dual-core intel
machine running OS X 10.5.4.
I have OpenMPI v1.2.3 installed. When I compile, I get
the message:
% gcc -fopenmp -O3 -DUNIX xxx.c -c
cc1: error: unrecognized command line option "-fopenmp"
Any help appreciated.
John
