[Question] Kernel Compilation for Modules

First post in the Dev section but this seemed to be the place to talk about kernel compilation and module development.
I have twice now, and am working on my third kernel compilation for the purposes of custom module building for the TF700 and the TF201.
The question I have has to do with the compilation process. Every time I have gone through this with the downloadable Asus Kernel zip I run in to several issues. Either missing references in code or portions that won't compile at all. Is this normal for kernel compilations? I would have thought that it would be fully compilable out of the box ( so to speak). Is it ASUS or just android/Linux in general that works out this way?
Is there a better way to do it? Should I use some generic source with the same version numbers? The current source is just not working at all. I am using an Ubuntu distro. Have the cross compile tools etc... but it just fails. I have already resolved two missing definition references and it just keeps on failing in new places
Hopefully this question doesn't offend developers. I have moved from WinPhone to here and want to better my understanding of how this should all work but need to start with some basics before I can make a meaningful contribution.
Thanks.
P.S... I looked and didn't find a "Compiling android kernels for dummies" book

"Dummies" doesn't write a book on kernel dev. Too wrapped up in telling people how to download iTunes.....
Use your "Google". And when you find it, Google XDA University.
There, you will find steps for setting a build environment and kernel and cross arm.
Understand, all kernels are different, but a good place to start. Plus, you learn how to use Google. An added bonus.
Oh... and... as an extra bonus, I will move this to Q & A, as this post has no development work attached. :silly:

My question wasn't HOW to cross compile. I have done it.
My question is WHY are there so many errors that need correcting when compiling the ASUS downloadable kernels and if this is typical of the source from any device or just ASUS?

I had to fix exactly one pair of quotes vs. angle brackets somewhere in the RIL - get the patch pack from my kernel and apply the ril include fix. Then it should compile. If not, you are doing something wrong.

Can you post any links or names of everything ill need to get started on cross compiling a kernel for my tf700t I download the source and get my config.gz and am running a ubuntu distribution but if you could post a link to a tutorial that has detailed instructions that will work for the infinity that would be greatly appreciated thankyou

Step 1: Get a suitable ARM toolchain. I can't help you here with Ubuntu because I'm using Gentoo and their crossdev tool (http://www.gentoo.org/proj/en/base/embedded/handbook/?part=1).
Step 2: Cross-compiling the kernel works just as for native kernels (make menuconfig, make), but you have to pass parameters to each make, e.g. make ARCH="arm" CROSS_COMPILE="arm-gentoo-linux-gnueabi-" (or whatever your toolchain is called)
Step 3: For the TF700-specific blob stuff I have written a detailed tutorial here: http://forum.xda-developers.com/showpost.php?p=36925180&postcount=4

How to create ROM for a particular device

Hello Everyone,
I am Ireen. Last few weeks I have been trying to build a custom ROM and I finally did it. But most important and confusing thing is how I flash this ROM to my device. I am not using popular device like HTC or Samsung I am using a Chinese tablet (MTK). So from this step what I have to do to flash this ROM to my device. On some tutorial they suggest to download kernel source code from HTC or Samsung website and add it to the ROM. If I manage kernel source code for this device then how I marge it with my ROM and prepare my ROM perfect for flashing into my device.?
I just need some guide lines. Any tutorial or thread link will help.
Thanks in advance.

How to port rom from HTC sensation?

I have an One s with S3 processer(villeC2).
Its specs are similar to sensation(with same cpu and screen resolution),but sensation has Android 7.1 ROM and one s only 4.4......
I would like to port a ROM for it from sensation.
Does anyone know how to do that?
Or if it is possible ?
(sorry for my bad english)
(my first post)

Some info !
Hi,
Actually I'm new in building roms and kernels, too. But i can share some info with you.
For starting this tutorial may be helpful: [Guide] Compile 4.2 & 4.3 & 4.4 Roms for villec2
As you can see, you will need "device", "vendor" and "kernel" source to build a rom.
Usually you can find source code of roms and kernels in xda threads and can start from those.
For example for Android 7.1 you can use RROS vendor and VilleC2 device and kernel sources. (Note: i don't know are these examples compatible or not?!)
And for kernel, maybe you has to upstream the kernel source to be compatible with new version of android that you want to build.
Good luck.
-----------------------------------
Edit:
After Compiling for myself, i figured out Vendor files for choosed rom (Lineage, RR, ..) will be included by their manifest files automatically. so for "Vendor" part in "local_manifest.xml" (or newer "local_manifests/roomservice.xml") we need to assign "proprietary_vendor" files related to our devices. "proprietary_vendor" files can be extracted manully if there isn't any online source.

[Kernel][6.0][for developers] M-Kernel by Metallice

Hi guys,
I want to present my port of M-Kernel, which was originally made by Metallice. This port has exactly the same functionality as the latest release from Metallice (a77), but was ported from Android 5.1 to Android 6.0.
Since this is a testing build only, it is currently provided as zImage only. You have to manually concatenate my kernel with the ramdisk of the ROM of your choice to be able to flash and use my kernel. For concatenating, you can use mkbootimg (click here), which is provided in my Github account.
You can get the source code and the kernel binary from Github (click here).
WARNING!!! This software is provided without any warranty. You use it at your own risk, although it is very unlikely for your device to get damaged due to my kernel.
I hope you enjoy my kernel! Feel free to ask questions about it, but please read the original M-Kernel thread before!
Best regards,
Oebbler

Thank you so much!
Something I didn't have the time or the skills to do!
I created an anykernel script for myself.

Hello,
If you are using Omnirom 6.0.1 by daniel_hk, you can flash the attached boot.img either with fastboot or with the TWRP image flasher. This boot.img contains my port of M-Kernel and the ramdisk files for Omnirom 6.0.1.
If you are not using Omnirom 6.0.1, you can try this image as well, but it may not work as expected. Please make sure you have a recent backup before modifying your device!
