There should already be a fix for this in the latest master branch in git. It will be included in rc3, but you can try building from git if you'd like. Ken On 01/13/2014 10:12 PM, Salmon, Rene wrote:

Thanks for the replies. Here is a bit more info. I tried this with both mpich 3.1rc2 and mpich 3.0.4

mpich 3.1rc2 ============ This seems to compile with out any error messages using gcc. ./configure CC=gcc CXX=g++ F77=gfortran FC=gfortran --prefix=/opt/ilocal/ --enable-fc make

mpich 3.1rc2 ========= This fails. I have the output of make V=1 at the end of this email. ./configure CC=icc CXX=icpc F77=ifort FC=ifort --prefix=/opt/ilocal/ --enable-fc make

mpich 3.0.4 =========== This seems to work with mpich 3.0.4. No error messages. ./configure CC=icc CXX=icpc F77=ifort FC=ifort --prefix=/opt/ilocal/ --enable-fc make

Here is the output to make V=1 for mpich 3.2rc2 using intel compilers. ================================

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

Might be the MacPorts garbage that bit me a while back too. If GCC fails, I suggest wiping MacPorts and installing Homebrew and the associated toolchain.
