CDO

Hello,

I am having a hard time getting CDO to recognise grib files. I keep getting the following error:

cdo mergetime *.grb merged_test.grb
cdo mergetime: Open failed on >test_GFS_004.grb<
Unsupported file type

I reinstalled cdo ensuring that the grib-api was included, following the example here: https://gist.github.com/jeffbyrnes/e56d294c216fbd30fd2fd32e576db81c

My cdo version now reads as follows:
