For our Intel compiler testing, we set CXX to icpc. I am not sure what
effect using icc will have here. If you try icpc for CXX, does it build?
I am thinking that perhaps somewhere in configure, using icc as the C++
compiler might be causing some issue. I am not sure yet. Could you try
using icpc and see if the same error happens? The warning message should
not cause it to fail.
