Cannot open module file ‘urbanparamstype.mod’

[Yuan Sun]

Hi all,

When I run ./case.build, there is an error:

/home/yuansun/Desktop/ForCodeTest/my_cesm_sandbox/components/clm/src/main/controlMod.F90:37:6:

37 | use UrbanParamsType , only: UrbanReadNML
| 1
Fatal Error: Cannot open module file ‘urbanparamstype.mod’ for reading at (1): No such file or directory
compilation terminated.

However, I have checked ''UrbanParamsType.F90' module whose module name is consistent with 'UrbanParamsType'.

If someone know what is wrong? Thank you.

Best,
Yuan

Hi all, I have solved this.

For future reference, while this is fresh in your mind, please write a few lines explaining how you solved it, if you don't mind.

Sure.

I found that ’make’ drops ‘UrbanParamsType.F90’ because of a circular issue.

The lndlog had a sentence: ‘make: Circular controlMod.o <- urbanparamstype.mod dependency dropped.

Then I checked the ‘UrbanParamstype.F90’ and the module I wrote with the mistake of ‘use controlMod : NLFilename’. It caused the ‘cmake’ to automatically drop ‘UrbanParamstype.F90’ from compiling.

My solution is that: Instead of using 'NLFilename from ‘controlMod.F90’, I used ‘NLfilename_in' from ‘clm_varctl.F90’ to solve this circular issue.

By the way, this error rose because I am modifying the code and writing the new module by myself. This error will not occur when running the default CTSM code.
