WRFv4.7.1 Compile error (possibly) at MYNN-EDMF reference

[smasters]

I am compiling the new WRF v 4.7.1. The compile is failing and I note fatal errors when it gets to the MYNN-EDMF submodule. It seems to be trying to use git, even though I downloaded the tar.gz file. The compile log is attached and the failure is around line 3105. The directory phys/MYNN-EDMF exists and has files and directories. I don't have git configured on this system using git for the compile is probably not a viable option. I didn't have this issue with my previous WRF compile (3.6.1), though it seems that the MYNN-EDMF directory is new.

The (possibly?) offending part of the compile is... (complete compile log attached).

Looking at the logfile, I think the actual error is arising from netCDF linking (first major compilation error):

diffwrf io_netcdf is being built now.

Though I'm not entirely sure what the exact issue is, and I can't find the equivalent set of symbols in my own installs of netCDF.

Solved...You were correct, the problem was with netCDF...Originally, I was pointing to an older build of netCDF. When I pointed to a version I built a few months ago, I got my WRF executables. Thanks for your help!

I still see the git errors in the compile log but, since the MYNN-EDMF files are already there from the tar.gz archive, the compilation completed successfully.
