K5 Making a ctng Toolchain for the Kindle Touch via Buildroot

Hi.

I am endeavouring to make a nicely matching toolchain for the kindle touch using cross-tools ng.

http://crosstool-ng.org/#download_and_usage

This is because for some reason - I haven't got to the bottom of - the kernel headers don't "install" as I would expect on the prebuilt Toolchains (linux/eink.h missing for example after installation)

So. I fired up make ctng-menuconfig.

selected 32bit little endian Cortex A8

GCC 4.5.4
eglibc 2.12

all the settings outlined in http://www.mobileread.com/forums/sho...6&postcount=17

and pointed it to a custom folder for my kernel /usr/local/src/BUILD_KERNAL_5.1.2/gplrelease

(setup the other stuff to sensible defaults)

I also then saved out the .config file to
~/GIT/k5ctng/toolchain/toolchain-crosstool-ng folder as a custom -kindle named config file for future reference.

.config was from here
~/GIT/k5ctng/output/build/build-toolchain/.config

and then run a make.

all software is not enabled, nor is busybox etc...

which fails with:

the file is indeed not exported (pictured) to
~GIT/k5ctng/output/host/usr/arm-unknown-linux-gnueabi/sysroot/usr/include/linux

it (cdev.h) does exist in the kernel sources however.

so I guess my question is in order to fix such an error am I to use an #ifdef something ? :bookworm:

or have I foofed in the config? :book2: is it not being pulled because of some slight versioning issue. am digging around for clues but all help accepted.

further details available upon request. Thanks : )
