Unable to enable UDUNITS, not UDUNITS2 about nco HOT 8 OPEN

NCO needs to know the absolute path to the UDUnits database on the system. You are compiling with relative paths, so the build might complete correct, and then fail at run time when UDUnits is no longer present at .../udunits-2.2.28. Please read the section on UDUnits in the manual here. You might export the database location with something like

export UDUNITS2_XML_PATH="${HOME}/anaconda/share/udunits/udunits2.xml"

from nco.

Apologies that I omitted the info. But it's a full path and I've censored the folder names.

Nevertheless, try the suggestion.

If I may be more specific with my question:
Is the error on UDUNITS complaining about udunits or udunits2. I'm not sure if I need to build and install udunits(1) or am I compiling udunits2 incorrectly. Once we clear this up it'll be easier to troubleshoot.

Please try the suggestion. It's a 1-liner!

Yes Ive already tested, after export I get the same error at runtime. Which was why I'd like to try recompiling it with your suggestion to add the xml path as well. Can I confirm its udunits2 we need here?

from nco.

Yes, UDUnits2. NCO wants to enable UDUnits2. If it cannot find UDUnits2 then it might try to enable UDUnits1.

from nco.

I have rebuilt and arrived at the same error still
