Libnetcdf not defined

Hello everybody,
I get “libnetcdf not defined” when i try to open a ncfile, using NCDatasets & NetCDF. I use Debian Buster, 32 bit. Julia 1.5.3.
Have you any idea to solve it ?
I already did this
"
using Pkg
pkg"add Conda"
Conda.runconda(install -c anaconda libnetcdf)
"
But the error still exists.

This is what i do:
using NCDatasets
ds = Dataset("/home//michael/file.nc")

ERROR: UndefVarError: libnetcdf not defined

Thanks for your support!

32-bit Linux? Wow. I don’t think these packages support this platform

Indeed, 32-bit version are currently not build for NetCDF_jll for Linux.

Are you using a 32-bit OS because, because of some restrictions on your hardware? (I am asking because sometimes people install a 32-bit version of their OS without known that they could also run a 64-bit version).

This pc is too old and support only 32-bit. Nevertheless, thank you very much !!

I just checked the status about HDF5 (which is required for NetCDF). Unfortunately, it is not build for 32-bit linux either. So it is not so easy to bring support for 32-bit Linux back. But previous versions of NetCDF_jll did support this architecture (for julia 1.5).

Maybe it works if you install these (slightly) older versions by using:

]add NCDatasets@0.11.2
]add NetCDF_jll@4.7.4

Maintaining builds on less used CPU architectures is quite some work. More volunteers able to dedicate some time would certainly make a difference.

In any case a more helpful error message would be nice. I am wondering if you did not see any message before when the package manager installed NetCDF_jll .

The problem is in particular that we can’t cross-compile HDF5, so we have to rely on whatever is available in the latest builds of conda

Hello,
While i install NCDatasets.jl or NetCDF.jl, i don’t get any error.
I install the older versions as you mentioned:
]add NCDatasets@0.11.2
]add NetCDF_jll@4.7.4
but i when i try to open a file.nc , i get the same error too:

– i also installed add NCDatasets@0.11.1 , but the same error. -
