CDO

Hello everyone,

I want to use CDO to convert .nc files to .grd file. I'm on Win 10, that's why I installed Cygwin, then switched to the folder the files are in with

cd  c:/mypathtofiles

and used the command I found on Stackexchange to hopefully convert it:

cdo -f nc import_binary in.nc out.grd

I also tried it the other way around (so grd to nc) but it gives me an error every time:

error while loading shared libraries: cyggomp-1.dll: cannot open shared object file: No such file or directory

• Double clicked on the exe and installed it in "C:\Program Files\cygwin64" - when a list of libraries (?) came up, I didn't pick anything because I didn't know what I'd need.
• I moved both the "cdo.exe" and the "cygeccodes.dll" file to a folder and added the path to it to Windows' PATH (environment variable).
• In Cygwin's console I switched to the folder with the "eccodes" file and unzipped it with "$ tar -xzf eccodes-2.9.0-Source.tar.gz"
• I created a new environment variable ("ECCODES_DEFINITION_PATH"), leading to the "definitions" folder within the just unzipped folder structure
• Afterwards I created the new bashrc file with "echo 'export ECCODES_DEFINITION_PATH=c:/mypath/eccodes-2.9.0-Source/definitions' >> .bashrc", which indeed created a ".bashrc" file in the "mypathtofiles" folder.
• I closed the console and opened a new one, then did what I wrote above.

What did I miss/why am I getting this error message?
