OK. Thanks
After I run "./configure CC=icc CXX=icpc FC=ifort F77=ifort" and "make all
install", some libs are installed to /usr/local/lib. These libs can not be
found when compiling my program, how should I do?

No worries; errors are to be expected in the config.log file. There's
a bunch of tests in configure that are designed to fail on some
systems (and pass on others). If configure finishes successfully and
you're able to build OMPI ok, then you can safely ignore the errors in
config.log.
