Errors running REAL, but can't find in namelist

Hi,

I'm running WRFv4.4.1 Intel and dmpar.
Classic netcdf without compression and no pnetcdf.
WPS is v4.4

I have a fatal error while running REAL.

FATAL CALLED FROM FILE: <stdin> LINE: 2797

I'm assuming <stdin> here is coming from the WRF namelist.output?
If so, namelist.output is only 2023 lines in size.
Where else is REAL taking namelist input from?

There are also a few errors in the log that I've never seen before regarding RRTMG-K. I've compiled with as default flags as possible.
It's a short log so I'm adding here as text.

Hi,
The real.exe program reads the namelist.input file. Can you attach your namelist.input file, as well as the configure.wrf file from when you compiled the code? Thanks!
 
Hi @kwerner

Thanks for having a look. I should've attached these initially!
The namelist.input only has 176 lines though.

I've also attached the log of the compile.
Unfortunately stdout and stderr are separate in the log but could shed some light.

Thanks for sending those. So the error message in your real.exe output is
Code: 
--- ERROR: RRTMG-based KIAPS schemes must be built with a default compile-time flag
--- ERROR: Run ./clean -a, ./configure, ./compile scripts again
--- NOTE: RRTMG radiation is used, namelist value for o3input (ozone input) is used

Because you are using the RRTMG KIAPS radiation schemes, the code must be built with a specific compiler flag. If you take a look in the configure.wrf file, look for this line:
Code: 
 -DBUILD_RRTMK=0 \

You'll need to change that "0" to a "1."

I would recommend going back to the top WRF directory and issue a 'clean -a' and then reconfigure. Once you do that, open the configure.wrf file and set that 0 to a 1, then save the file and then recompile the code. After that, you should be able to use this radiation scheme.
 
Thanks.
Ok the last note threw me off. I thought it had something to do with the namelist.
I did try to run with just the normal RRTMG and it ran fine.
I've compiled now for RRTMK enabled and will see.

Is there some documentation on any other compile time features?
I've looked in the compile guide and user guide and see nothing.
I see in the resulting configure.wrf there's a flag for RRTMG Fast as well.
 
I glanced through the Users' Guide and did not see anything about this requirement, so I just modified chapter 5 of the Users' Guide to add in this information. Thanks for pointing out the fact that it seemed to be missing!
