WRF V4.0.2 SCM compilation error

I am having trouble compiling WRF V4.0.2 for the SCM case (em_scm_xy). Compiling on V3.9.1.1 worked so I am wondering if this is a known issue for V4? Has anyone had experience compiling WRF SCM and can provide some insight?

I used option 13 (serial) for architecture and 1 for nesting. See attached configuration and compilation log file.

Thank you!

It seems that the log file is not a complete one.
Please type ./clean -a, then rebuild em_scm_xy and save the log file for me to take a look. Thanks.
It actually does look like your compile completed, but with errors. For any of the 2d or 1d idealized cases, you cannot compile with a nesting option. You must choose 0 (no nesting). So, first issue a 'clean -a', reconfigure with a serial/no-nesting option, and try to compile again. If it fails again, please attach your new configure.wrf and compile log.

At the beginning of configure.wrf, it shows

# configure.wrf
# Original configure options used:
# ./configure
# Compiler choice: 13
# Nesting option: 0

I believe the nesting option is correctly set to 0.

What confused me is that in the compile.log file, there is no error message to indicate anything wrong with the compiling of module_first_rk_step_part1.F. However, later it is complained that module_first_rk_step_part1.o doesn't exist.
A key point is module_first_rk_step_part1.F took almost 18 min to compile. This happens to me, too, with the Intel 17 compiler. My resolution was to edit configure.wrf and reduce the optimization level from -O3 to -O1
