Hi David,

Thank you very much for your helpful advice. After adding “-j 1” in compile code, my previous error were resolved. Now I can find wrf.exe, real.exe and tc.exe in /main/ folder, but there are still some errors compiling ndown.exe. It seems that /dyn\_em/solve\_em.f90 can’t get the module of twoway.

Here is my compile log file. Maybe there are some details I missed during compiling.
