ok, here's hoping this isn't another dumb question. i have a 64-bit
ubuntu 11.10 system, but i have a hand-rolled kernel (uname -r =
3.4.0-rc3) for reasons that have nothing to do with vbox -- just some
kernel work i'm doing.
given that this isn't the official 11.10 kernel, trying to install
the "official" ubuntu vbox packages fails since the modules can't be
built -- the kernel source is too new and there's at least one
incompatibility in a header file.
no problem, though, i'm not scared to build vbox from source so i
checked it out via "svn", did the configure, then tried to build:
$ kmk all
... snip ...

asm/unistd_64_x32.h: No such file or directory
compilation terminated.
... snip ...
i'm *guessing* this is because i chose to configure and build my new
kernel *outside* of the source tree using the "O=" make option, so
while my kernel source is in ~/k/git, the build itself is in
~/k/build, and it looks like the vbox build is looking only in the
source directory, or at the very least isn't checking the build
directory, since there is definitely a version of that allegedly
missing header file there:
build/arch/x86/include/generated/asm/unistd_64_x32.h
am i just missing the appropriate configure option to point at that
header file? the symlink under /lib/modules would certainly identify
where to find that header file:
$ ls -l /lib/modules/3.4.0-rc3/build
... /lib/modules/3.4.0-rc3/build -> /home/rpjday/k/build
what have i done wrong? thanks.
