To install kernel headers from your own kernel tree:
. first build them -
# assuming current working dir is the top of your kernel build
INSTALL_HDR_PATH=$PWD/usr make headers_install
should create a subdirectory path usr/include containing directories
such as linux video sound asm asm-generic and others
. then cd to /usr/include and, for each directory in
<kernel>/usr/include, first rename the one in /usr/include, then copy
(or symlink it if it will always be accessible) the one under the kernel
tree.

Thanks Allin! Very helpful, or at least, I'll let you know... ;)
One question, I have the 2.6.39.2 kernel tree that I'm building for my
little project. How do I point the udev build at the kernel headers in
that tree, e.g.:
/home/fwmiller/roadrunner/build/linux/include
where "linux" in this path is actually a sym link to a directory called
linux-2.6.29.2 in the same build/ directory?
Also, can I just do all the --disable-* options to configure? Is that
the base implementation?
Thanks,
FM

My next step is to get udev going. To that end, I've downloaded and
studied to some extent release 172. I'm using FC12 as my build machine
(e.g. gcc 4.4.2). This is what I think is supposed to happen, please
correct me if I'm wrong on any of this.
When I build udev, I do this:
configure --enable-static
This is to get the udev binaries to build without needing libraries.
Then:
make
I get this:
CC extras/input_id/input_id.o
extras/input_id/input_id.c: In function ‘test_key’:
extras/input_id/input_id.c:173: error: ‘BTN_TRIGGER_HAPPY’ undeclared
Your FC12 kernel headers are too old for building udev 172. I
believe you'll need at least 2.6.34.
Once I get the binaries built, I'll need to install them and the config
files in the proper places in my USB filesystem correct?
Naturally. Though you can reorganize the directory structure if you
wish via options to ./configure.
Thanks in advance for any assistance on this. I'd really like to keep
this as simple as possible. For example, its not clear to me what
"extras" are and how to turn them off if they are not needed.
./configure --disable-hwdb --disable-introspection \
--disable-keymap
(and so on). See ./configure --help and
