I’ve been trying to compile CCTM but keep getting different errors. I’ve solved a good amount of them, but I’m stuck again. First I’ll list off the software I’m using: I’m on Ubuntu (v22.04.3), using GCC compilers (v11.4.0). I installed NetCDF-C (v4.9.2) and NetCDF-Fortran (v4.6.1). I’m also using OpenMPI (v4.1.6) and I/O API (v3.2). First, I configure using `source config_cmaq.csh gcc 11.4.0`; the file looks like this: ```auto #!/bin/csh -f # ================= CMAQv5.4.X Configuration Script ================= # # Requirements: I/O API & netCDF libraries # # PGI, Intel, or Gnu Fortran compiler # # MPICH for multiprocessor computing # # Optional: Git for GitHub source code repository # # # # Note that this script was configured/tested on Red Hat Linux O/S # # # # To report problems or request help with this script/program: # # http://www.cmascenter.org/help-desk.cfm # # =================================================================== # #> Critical Folder Locations # CMAQ_HOME - this is where the config_cmaq.csh script is located.

I spent like 5 hours figuring out where everything was and I really made an effort to link everything correctly, but considering I’m new to linux and compiling stuff, there is a good chance I didn’t do it right. I’m not really sure how to ensure that the files I linked to are in fact the correct libraries/include files, since I didn’t even know what include files were up to like a week ago. Any pointers would be really greatly appreciated, and please consider that my knowledge about compiling is very limited. Thanks in advance! ---

You either need to fix this code to match what they want (probably not what you want to do yourself) or else you need to add `-std=legacy` to the Fortran compile-flags. ---

Thanks a lot for your reply! I added `-std=legacy` to `myFSTD`, `myDBG`, `myFFLAGS ` and `myFRFLAGS` in `config_cmaq.csh` (I added it to all just to be sure).

I also looked for errors regarding “flush3” but only found this post, so that seems like a dead end too. Maybe it would take less time in the end if I recompiled everything (NetCDF-C, NetCDF-FORTRAN, I/O API) from the beginning with a different compiler? GCC has been a little bit of a headache up until now. But maybe I’m so close that I might as well stick to it? Advice regarding this would also be appreciated. Thanks in advance! ---

These are different errors now (and at least one of them is an error which any good compiler should find): The `3600.0 * 10.0**-9` is really stupid and betrays a lack of competence on the part of the code’s author: this should have been `3600.0E-9` or `3.600E-6`. The code should not need the `FLUSH3` call, and if it did, it should have a declaration earlier in the code: > ``` > `LOGICAL, EXTERNAL :: FLUSH3` > > ``` By the way, this is not really a “_gcc_” model-build – it is a “_gfortran_” build; that is also a malapropism on the part of the _bldit_-system authors. – Carlie J.

Thank you for all your help Dr. Coats. I think I’m going to go ahead and restart compiling CMAQ, now with Intel compilers to see if I fare better. I appreciate the support!
