[SOLVED] Missing Directories?

Mark007 · 09-19-2012, 07:22 PM

Hi,

I tried to update to Virtual box 4.1, but it's all gone a bit pete tong.

So tried to roll back, to 4.0 and now we can't load a module.. to get the VMs started.

Code:

sudo /etc/init.d/vboxdrv setup
Stopping VirtualBox kernel modules                         [  OK  ]
Uninstalling old VirtualBox DKMS kernel modules            [  OK  ]
Trying to register the VirtualBox kernel modules using DKMSError! echo
Your kernel headers for kernel 2.6.18-308.8.2.el5 cannot be found at

and said log says

There's two broken symlinks... to !build

looking at where the symlink goes, we see.. no build directory..

btw, extra info.. Centos 5. loads of ram, disk and cpu resoruces free on a DELL box.

So the question is, how do we resolve this problem, that there's no "build" directory, surely I don't have to re-do the whole kernel ? or is dkms mucked up ?

I -think- I've found the problem, it's just how to go about fixing!

Cheers,

It appears that your headers are a different version from running kernel.

Mark007 · 09-20-2012, 02:13 AM

Thank you for that...

Bit more fiddling, and easiest way was to upgrade the kernel and libs, so that all relevant libs/headers/whatever where installed and sync'd properly..

VM machines now working..

Morel of story... too late at night/needed to step away !

Hi,
I am also encountering this problem, using CentOS 5.5 with a kernel 2.6.18-308.13.1.e15.
The /lib/modules/2.6.18-308.13.1.e15/build has a softlink to /usr/src/kernels/2.6.18-308.13.1.e15-x86_64 but however the folder doesn't exist.
Tried to do a update of kernel but there's nothing to update.
A little lost as to how to resolve this issue.

@dranix start a new thread so that you'll get the help you need, I'll be looking for it.
