CDO

Hi Hongzhi,

have you installed cdo with netCDF? What does 'cdo -V' return?

Hi Karin,

I've installed cdo with netCDF while I installed cygwin64.

Here's the screenshot.

Please,

cdo -V

sorry, my mistake

Hm, you have installed an old version (1.9.8) of CDO. The current version is 2.0.6. I would recommend to install a newer version.

Hi Karin and Hongzhi,

I have experienced those problems in cygwin64. It seems that wsl 2 works better. Did you try to install it in that environment? It is simpler than cygwin. Assuming that you have windows 10 or newer, you can follow these steps
1) Go to your powershell (windows>search>powershell). Then open as administrator (right click and select open as administrator)
2) type "wsl --install"
3) wait wait wait. Insert your wsl user and pass. wait wait wwait
4) type "sudo apt-get update"
5) type "sudo apt-upgrade -y"
6) type "sudo apt-get cdo -y"

This method installs cdo 1.9.9 because the default wsl machine is ubuntu 20.04. Even though it is not an updated version, it should work better than cygwin. If you want the most updated version you need to install miniconda or wsl ubuntu 22.04. It is a bit more complicate. You can find in this post how to install minicond and cdo in wsl

PS: bear in mind that if you computer is located in china as mine, you will have some problems fetching cdo files. You will need a vpn connection to succefully finish the installation

Hi Karin and Estanislao,

Thanks for your advises and suggestions.

I tried to install cdo-2.0.6 tar.gz yesterday, but failed in "make & make install" step. When there is the cdo-2.0.6 cygwin64 win-10 version, maybe it will work better?

I will try other platforms, such as wsl2 or ubuntu.

Thanks again

Hi Estanislao,

Thanks for your advises. It's very helpful, and cdo is working in Ubuntu.

Thanks again.
