To test that we have all the dependencies needed to run CDO navigate to the 'bin' folder and run the command ' ldd cdo.exe'. 'cdo.exe' is extracted and placed in the 'bin' folder of Cygwin.Īdd the Cygwin 'bin' folder to the System Environment Variables path variable.Ĭygwin can be started from the shortcut or by navigating to the base folder of the installation ' C:\cygwin64\ and running the batch file ' Cygwin.bat'.ĭuring the installation of Cygwin a user folder will have been set up … in my case 'C:\cygwin64\home\Mike'. * The only version of cdo that would run on my machine was found as a posting on the cdo forum here. The default folder 'C:\cygwin64\' was used. * Once all the packages have been selected you can press 'Next'. Gcc-core, gcc-fortran, libssl-devel, openssl, curl, zlib, netcdf-devel, udunits, proj, hdf5, netcdf13, libproj13, fftw3īy selecting “Full” you can use the search function to pick out the packages.
