Missing or broken 32-bit libSM.so.6 library

As of version 19.0, CrossOver no longer uses this library. This article left in place for reference only.


Up to CrossOver 12 this library was needed in order for Windows applications to bring up a graphical user interface. But starting with CrossOver 13 it was only used for integrating Windows Netscape plugins with Linux browsers.


CrossOver no longer uses this library (and cxdiag won't check for it) as of 19.0.

On CrossOver 17 and greater, the simplest solution to fix this issue is to run:

/path/to/cxoffice/bin/cxfix missinglibsm

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.

  • For 32-bit Windows applications
    32-bit Arch Linux : pacman -Syu libsm
    64-bit Arch Linux : pacman -Syu lib32-libsm
    Debian : apt-get install libsm6:i386
    32-bit Fedora : yum install libSM
    64-bit Fedora : yum install libSM.i686 libSM.x86_64
    32-bit openSUSE >= 11.2 : zypper install xorg-x11-libSM
    64-bit openSUSE >= 11.2 : zypper install xorg-x11-libSM-32bit
    32-bit openSUSE >= 12.1 : zypper install libSM6
    64-bit openSUSE >= 12.1 : zypper install libSM6-32bit


  • cxfix --show-all may have more up-to-date fixes.
  • 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.
