Unable to manipulate GRIB files with CDO
Added by U. Cordier almost 2 years ago
Hello,
I am trying to use CDO for an electronic project where I have to select certain types of data from a weather model (AROME HD).
I pretty much managed to install the CDO tool by following this YouTube video. https://www.youtube.com/watch?v=cuB00_xWk-0
I'm on Windows so it complicates things, so I use cygwin.
The install seems to have worked, as I can recognize the .nc files.
On the other hand, I have to manipulate grib files and there it doesn't work.
AzureAD+ordi2113604@PNL-R9131HLL /bin
$ cdo sinfov meteo.grib2
GRIB_API ERROR : Unable to find boot.def. Context path=/usr/local/share/grib_api/definitions
grib_context.c at line 216: assertion failure Assert(0)
Aborted (core dumped)
I took a random .nc file and it seems to work.

cdo sinfon: Processed 20 variables [0.06s 12MB]
Can you help me ?
Know that I have never used this kind of tools before and that I am not very comfortable with terminals, so please explain to me so that I understand well.

This is an old version, the current version is 2.0.5. Please install the current version.
RE: Unable to manipulate GRIB files with CDO - Added by U. Cordier almost 2 years ago
I deleted the cdo.exe file in the bin folder of cygwin. I added the latest version cdo.exe and cygeccodes.dll .
Then I install cdo by doing ldd ./cdo.exe , it seems to work, no error message.
Yet there is a problem, it does not respond to the instructions:
AzureAD+ordi2113604@PNL-R9131HLL /bin $ cdo -V AzureAD+ordi2113604@PNL-R9131HLL /bin $ cdo sinfon meteo.nc AzureAD+ordi2113604@PNL-R9131HLL /bin $
I don't know where the problem comes from.

Sorry, but here we need someone working with Windows 10 and cygwin to weigh in.
RE: Unable to manipulate GRIB files with CDO - Added by Estanislao Gavilan almost 2 years ago
Hi,
I have not been able to use remapcon in the windows version. Did you try to set a Linux virtual machine? cdo is more friendly in linux environment
Kind regards,
Estanislao

Thanks a lot !
Yes it works after installing an Ubuntu virtual machine.
It's still a pity that there is no functional version of CDO under Windows even though it is the most used OS.
