You do need to examine config.log and show it to us if you don't
Attempting to use the older C compiler and libraries to link .o files
made by the newer Fortran is likely to fail.
If you wish to attempt this, assuming the Intel compilers are installed
in default directories, I would suggest you source the environment
setting for the older compiler, then the newer one, so that the newer
libraries will be found first and the older ones used only when they
aren't duplicated by the newer ones.
You also need the 64-bit g++ active.
