I always build MPICH from git by hand. MacPorts broke my toolchain such that I could not compile MPICH or MPI-free Fortran applications. I believe GCC and/or binutils stuff was improperly told to generate/work with 32bit objects. Replacing MacPorts with Homebrew solved my problems. I suppose I could have reinstalled MacPorts (since it worked fine for me for over a year before self-destructing) but an expert advised me to switch. Jeff Sent from my iPhone

He's building with icc/ifort, so it's not being done via MacPorts. I don't think he even needs MP or Homebrew installed to build MPICH, just Intel's tools (and Xcode).
Building with 'make V=1' (or configuring with --disable-silent-rules) will provide more insight into what is going on. If you do have MP or Homebrew installed, you can rule out most interaction by removing their locations (/opt/local/bin, or /usr/local/bin, respectively) from PATH.
Jeff, I'm sorry to year you were unhappy with the (MP) tools. FWIW, it's been reworked to have a standardized MPICH version (with GCC's Fortan and the system's default C compiler) that is installed for use by any (macports-built) package that needs it.
Thanks, - Eric

It sounds like a 32-bit, 64-bit incompatibility between some installed compilers/linker. Are you able to build with gcc?

Hi,
Just trying to build MPICH 3.1rc2 on a Mac. The build seems to work but fails while trying to compile the examples. This is using the intel compilers.
ifort,icc version 14.0.0.074
Here is the config line. ./configure CC=icc CXX=icpc F77=ifort FC=ifort --enable-fc
