[Q] Build Kernel From Source

Been messing around with the Tiamat kernel to add a couple things, and now I need to build it, but I'm not exactly sure how.
Can someone point me to or explain how to do it exactly? I'm using a Wi-Fi Xoom so that's what I plan to build it for if that makes any difference.

Bump. Anyone?

I kinda answered this on the android kernel mailing list the other day as well.
https://groups.google.com/d/msg/android-kernel/U-Oo6WG8WFU/D9EmeFyn47sJ
To flash, download one of the kernel zip files I have released and update the modules and zImage in it.
It is important to note I use the prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- toolchain from AOSP to compile my kernels.

Sweet thanks. Going to try this out later today possibly.

It can't find your tool chain.

Well, I just attempted to build the current 3.0.23 kernel and when I do I get
Code:
kernel/bounds.c:1: warning: switch -mcpu=cortex-a0 conflicts with -march= switch
kernel/bounds.c:1: sorry, unimplemented: -mfloat-abi=hard and VFP
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2
this happens right after issuing the command of
Code:
ARCH=arm CROSS_COMPILE=../prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi- make
does anyone know how to fix this? Version 3.0.13 builds with no problems. Did something change? Should I be using a different toolchain now?

You will need to use this toolchain: git://git.teameos.org/eos/platform/prebuilts/gcc/linux-x86/arm/arm-linux-androideabi-4.6.git

I think you solved this, you should post a solution for future searchers

I would also like to know how you fixed this...

I don't remember fully but I believe it was a bad toolchain extension or download causing the problem

yeah, I'm definitely looking into building my own kernel for the note 2, so hope this could possibly help me. thanks again!
