CentOS 7, assorted issues

I'm trying to use CentOS 7 KDE as my primary OS, with the intention of building RPMs for missing packages and generally fixing issues myself. I'm a sysadmin for a number of CentOS 5 and 6 servers, so I figure it can't be that bad. I have encountered a number of issues with Crossover which I'd like to raise, especially since I recently renewed my support subscription:

1. nss-mdns.i686

This module is not available on the official or EPEL repositories. I have rebuilt the EPEL SRPM with:
   rpmbuild --rebuild --target i686 ./nss-mdns-0.10-12.el7.src.rpm

You may need to install various packages like gcc, make and glibc-devel.i686. I've hosted it in the hope someone will find it useful:

2. Skype

This just won't work. Crosstie or not. Every time I start the app, it crashes. I'm running it in a Fedora VM until Skype/CentOS fix the native client, or Crossover find a solution.


This just won't complete the initial "Updating" screen. Since this is officially supported, I would appreciate some assistance with this.

4. Running a .exe with the Dolphin context menu "Open with CrossOver (install)" fails

"KDEInit could not launch '/home/computerx/.cxoffice/desktopdata/cxoffice-0/cxassoc/Scripts/cxoffice-0:application_x-crossover-exe::install'"

I'm aware this isn't for official support, I thought I'd put it to the community first.

I noticed that it was released last week. We tested out RHEL 7 recently though we haven't yet completed a thorough round. When we do, we'd update this page:

Your information and feedback is very valuable. I'm concerned that won't work but I would attribute that to the absence of libnss-mdns. I believe we picked that up in the beta for the EPEL.

I'm also worried that launching applications is not working properly.

I haven't personally tried to use the Windows version of Skype in a long time... though now you've piqued my curiosity.

When you set this up, did you use CrossOver 13.1.3 or 13.2?

I did install the linked rpm and reinstalled crossover. Is there some way I can tell if this libnss-mdns isn't working correctly?

This is on 13.2.0.

I don't expect everything to work so soon after the distribution release (I had to modify the VirtualBox kernel module source to even get that running!) but it's nice to know you're investigating.

Sure. Turn on logging and search the log file for "failed to load". It should reveal the line that would speak to libnss-mdns not working properly.

At home where I was trialling CentOS 7, I eventually chickened out and ran back to openSUSE 13.1 with my tail between my legs.

I am now trialling it for work (where I persuaded them to buy a stack of crossover licences) so I'll be able to answer this one soon-ish.

Centos7 is roughly interchangable with fedora 19.

I got crossover working on my centos7 boxes just using the nss-mdns-0.10-12.fc19.i686.rpm.

With that build I've got everything working as promised.

A big thanks to Marc Gray for building and posting the nss-mdsn rpm!

by the way you can use for all rpm distros and skype natively works from there repository or you can download the rpm from skype. for most software i would recommend using the packman repository.

For those that still care, users of EL7 can use the nux-desktop repo to get the nss-mdns rpm.  Not sure how far back he has had this packaged up, but its there as of now.
