Comment 1 for bug 671369

Thanks for taking the time to report this bug. In order to understand its cause, we would need to know:

Which version and source of vmmon you are trying to compile. It is possible, however that you might not have the kernel headers installed. In the terminal, please make sure you do by running:

sudo apt-get install linux-headers-generic

Does this solve the issue?

I am setting the status of this bug as incomplete. Feel free to reopen it once you have the requested information and you are still suffering from it.
