Re: [arch-general] netcdf problem after arch update

Thanks all for your suggestions. Since I had to run only a couple more simulations using gasflow, I downgraded netcdf. I will upgrade again to the latest model once the simulations complete to avoid dependency problems in the future. On 05/12/2016 03:06 AM, Fulcrum wrote:

I feel stupid for not googling it.. Thanks! It solved the issue.

Of course you can downgrade package if you want. https://wiki.archlinux.org/index.php/downgrading_packages

Thanks for the reply.

Is is possible to revert back to the previous version of netcdf? Since one of the tools (pyscan) is a portable script, I don't know how can I 'rebuild' it to work with the newer version of netcdf.

Also, I would prefer it very much to avoid rebuilding the other tool (gasflow) because it takes a long time, and various other difficulties (It has many other dependencies which may cause other problems). It was a headache to install it in the first place.

Hi all,

I have two tools that use libnetcdf.so.7. They were working fine earlier. I updated Arch using the 'pacman -Syy' and 'pacman -Su'. But after the update, both the tools are giving errors:

Tool1 (gasflow) error: /home/foxtrot/project/gasflow-3.0/bin/xgf2: error while loading shared libraries: libnetcdf.so.7: cannot open shared object file: No such file or directory

Toos2 (pyscan) error: ImportError: libnetcdf.so.7: cannot open shared object file: No such file or directory

For future reference:

[eschwartz@arch ~]$ pacman -Fsx 'libnetcdf\.so' extra/netcdf 4.4.1rc1-1 usr/lib/libnetcdf.so usr/lib/libnetcdf.so.12 usr/lib/libnetcdf.so.12.0.0

Rebuild your software against the latest version of netcdf. Since it wasn't installed from the Arch Linux repositories, it is your responsibility to update it and make sure it is properly rebuilt as packages get updated.
