Upgrade to Oneiric breaks VMWare Player

November 28, 2011

After upgrading the Ubuntu install on my laptop from Natty to Oneiric my VMWare Player failed to start. It gave a error about not being able to compile the wmmon module. The compile process reported errors like:

/tmp/vmware-root/modules/vmmon-only/linux/driver.c:783:59: error: ‘SPIN_LOCK_UNLOCKED’ undeclared here (not in a function)

The fix was to repeat the official installation instructions. No need to remove the old one first. This upped the major version number in the progress.
