[Solved]Problem with compiling WRF_Chem V3.8.1

[Stella@88]

Hi everyone,

I am trying to compile WRF3.8.1 with WRF-Chem3.8.1, but I got some errors. I think I build my Libraries property and set the environment variables. Also, I can compile WRF-Chem v3.5, however, I cannot compile v3.8. Here is the error message.

module_ra_rrtmg_lwf.f90:8141:0:
use rrlw_ref_f, only : chi_mls
internal compiler error: in gfc_trans_use_stmts, at fortran/trans-decl.c:5111

Are there any suggestions or any solutions about that?
Thank you very much in advance

I have solved this issue. This is likely the same sort of problem as is mentioned here (3rd problem on the page): http://www2.mmm.ucar.edu/wrf/users/wrfv ... 9.1.1.html

The problem is that I am using a new GNU compiler (GCC 8.2.0) with an old WRF code. The fix is also similar. I attempted to correct the module_ra_rrtmg_lwf.F file for V3.8.1, and changed "use rrlw_ref_f, only : chi_mls" to "use rrlw_ref_f". Place the correct one in WRFV3/phys/ directory and then ./clean -a, reconfigure, and recompile.

I hope this information will be helpful.
