Hello Dave, It was a silly mistake on my part. I had an old mpif90 in /usr/local/bin/. The most recent release of mpich puts mpif90 in another area. I did not realize. I have been using mpich for so long, I did not realize the change. Thanks for pointing me in the right direction. Thank you, Doug. On Feb 23, 2013, at 10:31 AM, Douglas Dommermuth wrote:

Hello Dave,

Did I correctly configure the build:

./configure --prefix=/Users/dougdommermuth/mpich2/mpich-install CC=/usr/bin/icc FC=/usr/bin/ifort | & tee c.txt

When I look at the commands that you just sent me, it seems to be pointing to an older version of Fortran, whereas my logical links are as follows:

[dgd]% ls -al /usr/bin/ifort lrwxr-xr-x 1 root wheel 19 Feb 23 08:21 /usr/bin/ifort -> /usr/bin/ifort-13.0 [dgd]% ls -al /usr/bin/ifort-13.0 lrwxr-xr-x 1 root wheel 42 Feb 23 08:21 /usr/bin/ifort-13.0 -> /usr/bin/ifort-13.0-base/bin/intel64/ifort

Thank you, Doug.

I have attached the files that you requested (files.tar.gz). I could not find this file: mpich-3.0.2/src/pm/hydra/tools/topo/hwloc/hwloc/config.log. The output for compling pi3f90.f90 is below:

mpif90 pi3f90.f90 ld: library not found for -lSystemStubs

Did you upgrade to 10.7 (Lion) without reinstalling the Intel Fortran compiler? Most of the google hits I'm getting about this indicate that it can happen when:

1) you have an ifort version <12.1; or

2) you installed ifort, then upgraded from 10.6 (or earlier) to 10.7 (or later).

Obviously, #1 does not appear to apply to you. So maybe #2 does?

We do have some logic to add "-lSystemStubs" to the link line in certain circumstances, but your config.log file is showing that we are not doing that in your case:

----8<---- pac_cv_prog_f77_and_c_stdio_libs=none […] pac_cv_prog_fc_and_c_stdio_libs=none ----8<----

Further debug might be accomplished by inspecting the output of these two commands:

----8<---- mpif90 -show pi3f90.f90 mpif90 -v pi3f90.f90 ----8<----

The first will show the ifort command that MPICH intends to execute. The second will show the commands that the ifort compiler driver executes as it attempts to compile your program. This should show us which part of the stack is incorrectly adding "-lSystemStubs" to your link line. My guess is that it's your ifort install, based on the other information that you have sent so far.

-Dave
