Hello everyone!

virtualbox modules fails with the following

Presumably there isn't a Makefile in /usr/src/Linux?

If you've done a "make clean" or something similar in the linux source
directory (or if you've never built a kernel), you'll have to
re-generate at least the files required to build modules. Try doing
"make modules_prepare" in your linux source directory.

The full story is in

/usr/src/linux/Documentation/kbuild/modules.txt sectio 2.

sorry, i was in a hurry, i really should have asked more specific
questions. yes, there is no makefile in the kernel sources and that
causes all make commands in the kernel source dir to fail (of course).

i have the sources for 3.0.6 installed and configured emerge to change
the symlinks on install of kernel sources.
but... does emerge delete the older makefiles? why would it?

i hope there is a reasonable explanation for the makefiles
disappearing, i really can't use a failing HD at the moment.

well, i built the kernel i am running, is there a different way? :P

No it doesn't, but the /usr/src/linux symlink no longer points to a
directory containing a makefile.

/usr/src/linux
make oldconfig

will fix it.
