I am having trouble configuring OpenMPI-1.6.4 with the Intel C/C++ composer (12.0.2). My OS is OSX 10.7.5.
I am not a computer whizz so I hope I can explain what I did properly: 1) In bash, I did source /opt/intel/bin/compilervars.sh intel64 and then echo PATH showed: /opt/intel/composerxe-2011.2.142/bin/intel64:/opt/intel/composerxe-2011.2.142/mpirt/bin/intel64:/opt/intel/composerxe-2011.2.142/bin:/Library/Frameworks/EPD64.framework/Versions/Current/bin:/Library/Frameworks/Python.framework/Versions/Current/bin:.:/Library/Frameworks/EPD64.framework/Versions/Current/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin 2) which icc and which icpc showed: /opt/intel/composerxe-2011.2.142/bin/intel64/icc and /opt/intel/composerxe-2011.2.142/bin/intel64/icpc So that all seems okay to me. Still when I do ./configure CC=icc CXX=icpc F77=ifort FC=ifort --prefix=/opt/openmpi-1.6.4 from the folder in which the extracted OpenMPI files sit, I get ============================================================================ == Configuring Open MPI ============================================================================ *** Startup tests checking build system type... x86_64-apple-darwin11.4.2 checking host system type... x86_64-apple-darwin11.4.2 checking target system type... x86_64-apple-darwin11.4.2 checking for gcc... icc checking whether the C compiler works... no configure: error: in `/Users/geraldinehochman-klarenberg/Projects/openmpi-1.6.4': configure: error: C compiler cannot create executables See `config.log' for more details I'd really appreciate any pointers on how to solve this, because I'm running out of ideas on how to solve this (and so seems Google). Thanks! Geraldine
