As of version 16.0, CrossOver no longer uses this library. This article left in place for reference only.

Description

The OSMesa library is needed by some games and CAD-like applications to perform off-screen rendering.

Resolution

As of 16.0 CrossOver uses a newer version of this library. See the Missing libOSMesa.so.8 library page.
Current Linux distributions only provide newer versions of this library which cannot be used by older CrossOver versions.

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

/path/to/cxoffice/bin/cxfix missinglibosmesa

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
  Debian : apt-get install libosmesa6:i386
  32-bit Fedora : yum install mesa-libOSMesa
  64-bit Fedora : yum install mesa-libOSMesa.i686 mesa-libOSMesa.x86_64

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.
