Hi,
I use Linux PC and it seems that ifort has been well installed on my PC.
I try to install openmpi-1.4.2  to my computer.
I use this command to configure: ./configure CC=icc CXX=icpc FC=ifort F77=ifort F90=ifort F95=ifort  --prefix=/opt/openmpi
When it executes, i receive the following message:
 
***************************************************************
*****************************************************************
*** C++ compiler and preprocessor
checking whether we are using the GNU C++ compiler... yes
checking whether icpc accepts -g... yes
checking dependency style of icpc... gcc3
checking how to run the C++ preprocessor... icpc -E
checking for the C++ compiler vendor... intel
checking if C++ compiler works... no
**********************************************************************
* It appears that your C++ compiler is unable to produce working
* executables.  A simple test application failed to properly
* execute.  Note that this is likely not a problem with Open MPI,
* but a problem with the local compiler installation.  More
* information (including exactly what command was given to the
* compiler and what error resulted when the command was executed) is
* available in the config.log file in this directory.
**********************************************************************
configure: error: Could not run a simple C++ program.  Aborting.
