WRF 4.1 Warnings and Errors with Intel compiler

Hi all.

I am trying to compile WRF 4.1 with the Intel compiler with version 18.0.5 20180823. The compilation finishes successfully, but when reviewing the output file I find several warnings and several errors.

The warnigs are repeated a lot of these two types:
gen_comms.c(1229): warning #303: explicit type is missing ("int" assumed)
REGISTRY WARNING: o3rad: o3rad_b is not a variable or number; ignoring it

And the errors go above all like this:
icc: error #10236: File not found:  'all'
icc: error #10236: File not found:  'big_endian'
make[2]: [bobrand.o] Error 1 (no tiene efecto)

For the compilation I used "Suggestions for timing improvements from Craig Mattocks" that in previous compilations worked very well.

I've done a couple of tests and I'm having some performance problem, I do not know if warnings and errors can influence or can be eliminated with a flag. Attachment "configure.wrf" and "compile.log".

Thank you.

Would you please compile WRF with just one processor (e.g., setenv J "-j 1" in csh)? In this case we will know when and where the first error popped up. Other errors may derive from the first error.
I have recompiled the model with a single processor. I attach the new file.

When I tailed your compile.log, here is what I see:

build started:   mié may  8 18:03:13 WEST 2019
build completed: mié may 8 18:54:44 WEST 2019

-rwxr-xr-x. 1 root root 59592944 may  8 18:53 main/wrf.exe


It looks like the build is successful.
Correct, the compilation ends correctly. But then my question is, to what can these errors be due? Do they influence the final behavior of WRF?
