I'm getting this error when running VirtualBox's installation script:

$ sudo ~/Downloads/

        include $(srctree)/arch/x86/Makefile_32.cpu
        # FIXME - should be integrated in Makefile.cpu (Makefile_32.cpu)

Before upgrading to 3.X I didn't have this problem, the script would install VB correctly. Any ideas on what might be causing this?

Thanks in advance!

The problem is that /usr/src/linux-headers-3.2.6/arch/x86/Makefile_32.cpu does not exist. Copy the header file from github to the proper directory and then try installing virtual box again.

You mean my kernel source is missing files? Weird, it was installed from the repository. Will try. – m0skit0 May 13 '12 at 16:50
