[MITgcm-support] disabling NETcdf

[Neil Patel]

Thanks everyone for your help. I ended up using an ifort compiler, which seemed not to need the -D_d=D option so I left it out. However, once I ran mitgcm I got this error message:

exp2/build> ./mitgcmuv > output.txt
./mitgcmuv: error while loading shared libraries: libnetcdff.so.5: cannot open shared object file: No such file or directory

I don't where (or if) NETcdf libraries are installed, nor am I interested in using them. I didn't think my opt file had any lines for NETcdf, so I'm puzzled why it's accessing netcdf. To be sure, I added the -disable=mnc keyword to make sure. Here's my optfile:
