Mageia forum

Hi,
I am using Mageia 64 bit, and using an application (crossoffice) and I get an error:
"Missing 32bit libnss_mdns.so.2 library: This library is needed for network and Internet access."

If I use urpmf to get the file, the urpmf tool seems to tell me that the 32 bit version is installed:

Code: Select all

[root@matrix ~]# urpmf --verbose libnss_mdns.so.2

But the 32 bit version of the file does not appear in the /lib directory

Code: Select all

[mike@matrix ~]$ ls -l /lib64/libnss_mdns.so.2
-rwxr-xr-x 1 root root 10400 Jan 15 07:49 /lib64/libnss_mdns.so.2*
[mike@matrix ~]$ ls -l /lib/libnss_mdns.so.2
ls: cannot access /lib/libnss_mdns.so.2: No such file or directory


Does anyone know if this file should be available in the repositories? I do have the 32 bit core release enabled.
Thanks

urpmf tells you what package a file is in. It does not tell you if that package is installed.

nss_mdns is in the 32 Bit Core Repository, but urpmi will not let you install it because there is a 64 bit package with the same name. It will not let you have both versions installed at the same time.
You could uninstall the 64 bit version and then install the 32 bit version with the command

Code: Select all

urpmi --wget ftp://distrib-coffee.ipsl.jussieu.fr/pub/linux/Mageia/distrib/1/i586/media/core/release/nss_mdns-0.10-9.mga1.i586.rpm

That is assuming you do not have anything installed which needs the 64 bit version.

There is a real need for the 32 bit library. Here is the answer from the Codeweavers support:

Code: Select all

Typically, winecore is going to try find the 32bit library by walking $ldpath ; if the distro uses '../lib64', you may see 'lib32' or just plain 'lib' directories, and these will be in /usr or /opt/ depending on distro...

..it's entirely sane & legitimate to have both the 32 & 64 bit versions of the same library installed ; they can have the same namespace so long as they are nested in their respective directories. You -should- be able to do this -> http://www.codeweavers.com/support/wiki/diag/missinglibnss_mdns

There should be a possibility to have the 32 bit version under a lib32 directory of a Mageia x86_64.
