A getenv issue in gen_domain.F90 of CLM5

[Zhengjy]

I'm referring to 1.6.3.5 of the CLM5.0 User's Guide, from the URL https://escomp.github.io/ctsm-docs/...rs_guide/running-single-points/running-single -point-configurations.html#example-creating-a-surface-dataset-for-a-single-point. After executing ./gen_domain -m $MAPFILE -o $OCNDOM -l $ATMDOM in gen_domain_files/, I reported an error:
(shr_sys_getenv) ERROR: no implementation of getenv for this architecture
(shr_sys_getenv) no implementation of getenv for this machine

The picture is my running flow process. I would be very grateful if you could help me point out the problem.

Not sure, but this post:

CAM5 stopped at initialization with shr_sys_getenv error

Hi, all, I was trying to use CESM1.2.2 to run a test with T31_g37 resolution (B1850cam5CN) since CESM2 is too computational expensive for paleosimulation. However, CAM5 stopped at initialization stage with following error: (shr_sys_getenv) ERROR: no implementation of getenv for this...

implies that:

"The OS isn't being recognized as one that supports getenv."

So maybe you need to consult with your system administrators.

Hi, it's been a long time since I solved this problem, but I can give you a suggestion, maybe you can rewrite the .F90 file in this step, and then modify the code that determines your host name so that it passes the judgment, which is about line 747 of the file.

"Thank you for the response，bro! I resolved it by recompiling in the src directory. Now, I would like to ask how to set up parallelism? My mpirun always runs on a single CPU, and it's frustrating!"
