Ah, this is a simple problem. Don't override the CC/etc. for the
lamtests suite; it should default to mpicc and friends. If you
override the CC for the lamtests configure, it'll use those compilers
directly (not mpicc and friends).
Make sense?

I run "./configure CC=icc CXX=icpc FC=ifort F77=ifort" and "make all
install" to install open mpi. The config.log can be got in the
attched tarball. After these two command, mpic* commands seem to work.
[root@xblade08 wwh]# mpicc --showme
icc -I/usr/local/include -pthread -L/usr/local/lib -lmpi -lopen-rte -
lopen-pal -ldl -Wl,--export-dynamic -lnsl -lutil
[root@xblade08 wwh]# mpif77 --showme
ifort -I/usr/local/include -pthread -L/usr/local/lib -lmpi_f77 -lmpi
-lopen-rte -lopen-pal -ldl -Wl,--export-dynamic -lnsl -lutil
Then I used open mpi to compile lamtests 7.1.4, downloaded from http://www.lam-mpi.org/7.1/test-suite.php
. "./configure CC=icc CXX=icpc FC=ifort F77=ifort" failed with
following message:

Can you send all the information listed here:
http://www.open-mpi.org/community/help/
And also the output you're seeing when your application fails to
compile.
Thanks!
