CESM 2 submit error: Can't locate XML/LibXML.pm

[tylerh]

Hello,

I am trying to run CESM 2 with compost F2000climo and resolution f09_f09_mg17. I am able to create the case, complete the set up, and build the case. When I go to run the case, I get an error message saying "can't locate XML/LibXML.pm" (the error message is attached below). I've run a case with compost B1850 and resolution f19_g17 on CESM2 previously and did not receive this error message. Any help is much appreciated!

Have you tried recreating the F2000climo case. Since B1850 worked for you, it leads me to believe there could have been some kind of a filesystem issue.

Hey Chris,

I just tried to create another case with the same inputs. I now get the same error message at the build stage.

Hi Tyler,

Does the B1850 case still work for you?

Hey Chris,

Looks like that is not working for me either now. That compost worked fine for me prior to attempting to run the F200climo.

I wonder if your code or environment was somehow corrupted. Try doing a fresh login to the system, then download the model to a different
directory and try that.

Hey Chris,

I just tried this. I download the code again into a new directory (my_cesm_sandbox2). I also ran this code (./manage_externals/checkout_externals -S) to make sure everything downloaded properly and I didn't get any errors. I got the same message again during the build stage.

Hi Tyler,

I was able to build and run an F2000climo case using your sandbox. There's probably an issue with your user environment. Did you change anything, or log in differently since you had success with the B1850 case?

Hey Chris,

Not that I am aware of. I am new to using Cheyenne/CESM, so I may have unintentionally done something to my user environment. Is there a way for me to check this?

Thanks!

Also, what commands are you using to configure and build your cases?

 

[tylerh]

These are the steps I'm taking:

1) In the my_cesm_sandbox/cime/scripts directory:
./create_newcase --case ~/cases/(case name) --res (resolution) --compset (compost) --project (ProjectID)

2) In the cases directory that I just created:
./case.setup
qcmd -- ./case.build

Those commands should work just fine. Something in your environment must be tweaked. Have you been
running any python tools?
