CESM 1.2.1 new case create error

[Yuanhang]

Hello, everyone!

I am trying to port CESM1.2.1 to my personal computer:
<OS>LINUX</OS> (Ubuntu 20.04)
<COMPILERS>intel</COMPILERS>
However, when I created a new case, some errors occurred. I ran the following command:

yuanhang@yuanhang-Lenovo-Legion-Y7000:~/cesm1_2_1/scripts$ ./create_newcase -case test -res f19_g16 -compset X -mach userdefined

And here is the error:

/home/yuanhang/cesm1_2_1/scripts/ccsm_utils/Case.template/ConfigCase.pm has too many errors.
Compilation failed in require at ./create_newcase line 361.

I tried to change different machines and define my own machine but the error still occurs. How should I do?
Any suggestions are appreciated.

Best wishs,

Hello！
Maybe your purl version is too new.
You can try modifying the file "ConfigCase.pm" by changing line 448 from

foreach my $model qw(COMP_ATM COMP_LND COMP_ICE COMP_OCN COMP_GLC COMP_ROP COMP_WAV)

to

foreach my $model (qw(COMP_ATM COMP_LND COMP_ICE COMP_OCN COMP_GLC COMP_ROP COMP_WAV))

Just add a pair of parentheses.
