CrossOver Support - Community Forums

after i install crossover, i get this error: Missing libnss-mdns 32-bit library
I install: pacman -Syu nss-mdns

But error is even there. I found nothing in the internet. I think it could be the update from avahi, but i'm not sure and have no solution. Maybe someone can help out.

Also i can not log me in in the app, but here i can do? Don't understand why

I don't know Manjaro, but in Ubuntu you have to install the 32-bit versions of the libraries. I'm guessing in your case it would be something like "libnss-mdns:i386" maybe? Can you run cxdiag? On my system it is in /opt/cxoffice/bin/cxdiag and there is one for 64-bit bottle diagnostics as cxdiag64, but I think most bottles are 32-bit.

As an Arch user, I will tell you this:

1) You're probably running in 64bit, and you need 32bit libraries for Crossover, usually named lib32-somelibrary. If it doesn't start with "lib32", you installed a 64 bit library.

2) multilib: In /etc/pacman.conf, make sure to uncomment the multilib repo. It might be already done in Manjaro, I don't know.

3) Not sure about Manjaro's repos, but for Arch, lib32-nss-mdns is in the AUR, so to install that, you need to use yaourt (which I believe is the default in Manjaro):

yaourt -S lib32-nss-mdns

Not sure how much you need host name resolution via mDNS...

Thank you for your help, lib32-nss-mdns was missing.

Cool. There are a few Arch/Antergos/Manjaro users here, so there are people that can help when needed.

The mentioned lib is a 64-bit library. You can verify the existence with

pacman -Ql nss-mdns

There is a 32-bit library in AUR so you must use the installation methods available for AUR packages.

If you are on Manjaro pamac-manager is installed but needs AUR enabled from settings.
On Manjaro yaourt is installable from the official repo.

yaourt -S lib32-nss-mdns

I got the same error that '32bit libnss_mdns_so.2 library is missing'. Then I tried 'yaourt -S lib32-nss-mdns', got the following error:

It builds fine on Arch, so this is either specific to your install, or to Manjaro as a whole.

You might want to try updating your system first, and then try again. If it doesn't build, you should try the Manjaro forums.

I looks like you are missing the compiler which is a part of the base-devel package.

sudo pacman -Syu base-devel --needed

Then you should be able to build and install with

yaourt -S lib32-nss-mdns

I encountered the same issue with 64-bit Mageia 6.

The 32-bit library is named libnss-mdsn2 and is not installed by default.
The incantation to install it is # /usr/bin/urpmi libnss-mdsn2 .

I tried the suggested method, still got the same error

Finally, I was able to install lib32nss-mdns by downloading the deb from the link below and then install it using debtap and pacman -U. I can see the file libnss_mdns.so.2 under /usr/lib. However, when I tried to open Crossover, it still shows the error 'Missing 32bit libnss_mdns.so.2'. Any suggestion? Thanks.

I don't know why it won't build for you as the package compiles fine at my system

I suggest you uninstall it then download and install the package from this location.
The package is gpg signed with official Manjaro key.

Hi Frede,

Thank a lot for your help! The error is now gone after installing the package from the link you provided.

don't use yaourt (its dead), use yay as an alternative.

Or pamac

pamac -h

I had the same trouble with the libraries when installing into Manjaro.
I tried several solutions, but the only thing that worked was the easiest solution.

I installed WINE in Octopi and it installed all the missing libraries.
Crossover now works perfectly.
