Description

The X11 library is needed to display the graphical user interface of Windows applications. Without it no graphical Windows application can work.

Resolution

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

/path/to/cxoffice/bin/cxfix missinglibx11 missinglibx11.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.

• For 32-bit Windows applications
  • 32-bit Arch Linux : pacman -Syu libx11
  • 64-bit Arch Linux : pacman -Syu lib32-libx11
  • Debian : apt-get install libx11-6:i386
  • 32-bit Fedora : yum install libX11
  • 64-bit Fedora : yum install libX11.i686 libX11.x86_64
  • 32-bit openSUSE >= 11.2 : zypper install xorg-x11-libX11
  • 64-bit openSUSE >= 11.2 : zypper install xorg-x11-libX11-32bit
  • 32-bit openSUSE >= 12.1 : zypper install libX11-6
  • 64-bit openSUSE >= 12.1 : zypper install libX11-6-32bit

• For 64-bit Windows applications
  • Arch Linux : pacman -Syu libx11
  • Debian : apt-get install libx11-6:amd64
  • Fedora : yum install libX11.x86_64
  • openSUSE >= 11.2 : zypper install xorg-x11-libX11
  • openSUSE >= 12.1 : zypper install libX11-6

Notes:

• 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.
