This library is only needed if /etc/nsswitch.conf specifies 'mdns4' or 'mdns4_minimal' on the 'hosts' line. This is only known to be the case on Debian and Ubuntu systems.
When this library is needed, it is used to resolve host names; so its absence will break most network and Internet applications.
On CrossOver 17 and greater, the simplest solution to fix this issue is to run: /path/to/cxoffice/bin/cxfix missinglibnss_mdns missinglibnss_mdns.amd64
Or add --show-all to see how CrossOver would fix it on your platform and others.
Alternatively you may try one of the commands below.
The commands usually also apply to newer versions of the distributions above as well as derived distributions. So for instance a fix for Debian 7 may still be valid for the latest Debian Testing and is typically also applicable to Ubuntu, Linux Mint, Deepin and Pop! OS. Similarly a fix for Fedora likely also works on Red Hat Enterprise Linux, CentOS, etc.
(1) : The lib32-nss-mdns package is available from the standard multilib Manjaro repository. However Arch users will have to get it from an AUR repository.
(2) : Note that on Debian 7 and Ubuntu <= 14.04 attempting to use libnss-mdns:i386 will cause the package manager to try replacing the 64-bit libraries with the 32-bit ones, thus breaking 64-bit Linux applications.
Mageia 2 and 3 users running the 64-bit version will need to manually download the nss-mdns library and install it via the rpm:
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
