[OMPI users] Problem compiling openmpi-1.2.3 on Core 2 Duo with icc
Hi all, I noticed some problem in the compile of openmpi-1.2.3 on a Core 2 Duo processor using intel compilers (icc Version 10.0). I have attached the output of make. This problem does not exist in openmpi-1.2.2 which I have compiled and run successfully on the same machine with the same compiler. David.
