Hi there!

I would like to get started with building kernels for my newly bought Huawei Honour U8860

My motivation comes from the desire to have this app running on my device, which apparently needs some kernel patches to be applied, since I'm missing the devicefiles called /dev/voc* --> http://code.google.com/p/rvoix/
The Kernel patches can be found here: http://code.google.com/p/rvoix/source/browse/#svn/branches/snapdragon/kernel

What I found on my own is this:
http://source.android.com/source/building-kernels.html

But I have no idea what kernel to start from, the list of devices they have over there
http://source.android.com/source/building-devices.html
have names like: "maguro, panda, wingray, crespo, passion, sapphire, dream" and I have no idea what they mean, except for those few names that are explained on the same page.

I am currently running a rooted Android 4.0.3 that I gained by following this guide:
http://forum.xda-developers.com/showpost.php?p=22688341&postcount=53

I would really apreciate any help anyone can give me! Thanks in advance

EDIT: okey!! I found a download from huawei here
http://www.huaweidevice.com/worldwide/technicaIndex.do?method=gotoProductSupport&productId=3834
Thats called: "open source-kernel-3.0.8-U8860-IcecreamSandwich"
http://www.huaweidevice.com/worldwi...=toDownloadFile&flay=software&softid=NDQwNDc=
So I will try to work with this and get it build and deployed on my device. Thats gonna be a lot of work, will report back when I finished or aborted my mission frustrated.

EDIT2:
Okey, this is really a hard thing if you don't know what you're doing, like me... I think I'm gonna give up, all these config options (i stopped reading after the first 50 and just hold down the enter key for agreeing to the default), and in the end some strange errors:
..._kernel/arch/arm/include/asm/irqflags.h:11:5: warning: "__LINUX_ARM_ARCH__" is not defined
error, forbidden warning: irqflags.h:11
make[1]: *** [arch/arm/kernel/asm-offsets.s] Fehler 1
make: *** [prepare0] Fehler 2

About my initial motivation for compiling myself a kernel:
There are a lot of call recording apps, though most only record from the microphone, and therefore only record a weak shadow of the other side of the conversation.

For the moment I stick with this one:
https://play.google.com/store/apps/details?id=androidlab.allcall

When I tested it with a few testcalls, it seemed to me that the other side is also recorded, even though it gave me an error that it can't record the other side. However, now after a few days real usage I'm not so sure if it truely records the other side, or if this is only this shadow that comes in through the mic. It is hardly understandable in the recordings most of the times now.

So this alternative app is at least an interim solution, but I still wan't to get myself a kernel compiled, and once done try to apply or adept the kernel patches from http://code.google.com/p/rvoix/ to this kernel

Okey. So about building this kernel from huawei. From googling a bit I learned that this error
Code: 
...arch/arm/include/asm/irqflags.h:11:5: warning: "__LINUX_ARM_ARCH__" is not defined
error, forbidden warning: irqflags.h:11
make[1]: *** [arch/arm/kernel/asm-offsets.s] Fehler 1
make: *** [prepare0] Fehler 2
stems from problems with the toolchain used for building

But first let me document a bit how I got this far:

1.) download the kernel sources from:
http://www.huaweidevice.com/worldwide/technicaIndex.do?method=gotoProductSupport&productId=3834&tb=0

2.) get the kernel config from the device, by connecting it via usb, turning on the usb debugging on it and then using
Code: 
adb pull /proc/config.gz
to fetch it. unpack it and put it into the same directory as the extracted kernel, but by the name ".config"
--> learned this one from http://mjanja.co.ke/2011/06/compiling-custom-kernels-on-the-huawei-u8150/

3.) Download and extract an android NDK

4.) open a terminal and set up a few environment variables:
Code: 
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=/path_where_i_extracted/android-ndk-r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-

5.) simply call make. I also tried to run "make menuconfig" before running make, since a few sources stated it would be neccecary, but that didn't change the error I got.

This guy here states that 7b is not good and 5c is the way to go, but this error kept the same.
http://www.android-hilfe.de/root-ha...deos-x3/172743-kernel-selbst-kompilieren.html

So I looked into ubuntu and found that there is also an arm gcc toolchain, and got it by simply installing this package:
Code: 
sudo apt-get install gcc-arm-linux-gnueabi

and since the system puts its stuff all into the proper path so you can use it easily just call
Code: 
export CROSS_COMPILE=arm-linux-gnueabi-

and afterwards again "make" and I got a new and different output:
Code: 
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: »include/generated/mach-types.h« ist bereits aktualisiert.

But well. I also can't make a lot of meaning out of this... So still looking for help on how to get myself a kernel compiled

Okey, big progress! I found this string somewhere:
Linux version 3.0.8-perf ([email protected]) (gcc version 4.4.3 (GCC))
#1 PREEMPT Tue Mar 6 17:48:17 CST 2012

This told me, that this kernel can be built with gcc version 4.4

I looked into ubuntu, and found this version is also available in the repository. So I removed the standard version which is 4.6 and installed 4.4 --> now the kernel seems to build. I'm gonna leave the PC runnign over night and look in the morning at the results.

If someone wants to redo my steps:
the ubuntu package you need is "gcc-4.4-arm-linux-gnueabi"
be sure to remove all other arm gcc packages, and then set a link:
Code: 
ln /usr/bin/arm-linux-gnueabi-gcc-4.4 /usr/bin/arm-linux-gnueabi-gcc

EDIT: so the "make" command finished without any error messages. So next step is to find out how to pack the builded kernel into a boot.img to deploy it to the device.

Okey! So I finshed the whole process! I am now able to build and deploy the 3.0.8 kernel sources released by huawei!

I will document the steps for reproducability:

-) Install and link the arm gcc version 4.4
Code: 
sudo apt-get install gcc-4.4-arm-linux-gnueabi
sudo ln /usr/bin/arm-linux-gnueabi-gcc-4.4 /usr/bin/arm-linux-gnueabi-gcc

-) Download the Kernel sources from
http://www.huaweidevice.com/worldwide/technicaIndex.do?method=gotoProductSupport&productId=3834&tb=1

-) Unpack Kernel and cd into it.

-) Get the original Kernel config from your device like this:
Code: 
adb pull /proc/config.gz
then unpack it into the Kernel directory and rename it to ".config"

If you want, you can adjust it with any texteditor, or by calling "make menuconfig" but for this you should first export the variables below so that make knows you want to build for the arm platform, not for x86

-) finally build the Kernel like this:
Code: 
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-linux-gnueabi-
make

-) I found the easiest way to deploy the built kernel is the following:
install the package abootimg
Code: 
sudo apt-get install abootimg

and then make a copy of some preexisting boot.img (look at your device either with the pink screen mode or with certain custom ROMs that are not built as "production build" you can directly see the folder /.cust_backup/image

warning, this copy will be directly edited, so be sure to have another copy of the same image somewhere else.
Okey, now replace the path to your built kernel and the path to your boot.img and run:
Code: 
abootimg -u path/to/bootimg/boot.img -k /path/to/kernel/arch/arm/boot/zImage

thats it, this replaces the kernel from this boot.img with your newly built kernel and can be written to folder /.cust_backup/image (be sure to keep a backup of your previous boot.img) and then reboot your device - voilà!

EDIT: This deployment method does not include deployment of kernel modules, for that you need more complex deployment methods as for example described here:
http://forum.xda-developers.com/showthread.php?t=916198

For making a custom kernel just adjust the sources between download/unpacking and building :)

thanks for your effort mate.... good job!

a noob question, what is kernel for?? mind to explain for me??? I've flash to MIUI 4.03, rooted, overclocked, but except kernel. any difference?

Click to expand...
Click to collapse

Well.. its the inner core of a linux operating system, such as android. originally linux = the kernel, but since people are lazy whole distros are for simplification just called linux.

Hi kaefert,

I'd like to work on the U8860's kernel but I don't have the .config file.
Could you give me the config.gz file please ?

Thanks

I've managed to create a Kernel that works with B919 based ROMs, but the camera is non functional..
If anybody wanna try it, get it here: http://kaefert.is-a-geek.org/huawei_honor/boot_MIUI_Germany_2-7-13_rvoix.img

something that might come in handy for people wanting to do kernel developing on the huawei honor (I needed it right now and thought I'll document it here for others)

You probably know that the boot.img is to be placed in
/.cust_backup/ or spoken device wise /dev/block/mmcblk0p1

in some ROMs after the boot has completed this is mounted read only. In this case you can remount it in write mode like this:
Code: 
mount -o rw,remount /dev/block/mmcblk0p1 /.cust_backup/

In other cases its not mounted at all, then you can mount it directly as in readwrite mode like this:
Code: 
mount -w -t vfat /dev/block/mmcblk0p1 /.cust_backup/

I will not help / cooperate with forum terrorists that full-quote extremly long posts. This kind of behaviour distroys any readabilty of this forum thread
UPDATE: I will give you a more meaningful answer if you edit your post and only quote the part that you are talking about.

Okey.. well when I wrote up this guide, I used Ubuntu 11.04 = Natty Narwhal.

There is a site from ubuntu on http://packages.ubuntu.com/
And when you search this site for the package I mentioned, you will be lead to this page:
http://packages.ubuntu.com/natty/gcc-4.4-arm-linux-gnueabi
where you can see that this package is included in [natty] [oneiric] [precise] [quantal]

You mentioned you are using Ubuntu 10.04 LTS = Lucid Lynx --> Which is still supported by Ubuntu since its LTS.. But as you might have guessed: I am not Ubuntu staff ;) So just get a more recent Linux distribution. I would recommend Linux Mint 13 with Cinnamon desktop.

Hey kaefert,

I am actually learning and trying to build the kernel myself.
I've had success but however, the zImage output that results is actually larger than the one in the boot.img of my phone.

I can't use the abootimg to replace the kernel because of it.

Did you encountered this problem too? Any reasons why? :confused::confused:

yes the image can vary in size, but that shouldn't prevent abootimg from working..?

This is the error I get when I try to use abootimg:

Code:

    Okey! So I finshed the whole process! I am now able to build and deploy the 3.0.8 kernel sources released by huawei!

    I will document the steps for reproducability:

    -) Install and link the arm gcc version 4.4
    Code: 
    sudo apt-get install gcc-4.4-arm-linux-gnueabi
sudo ln /usr/bin/arm-linux-gnueabi-gcc-4.4 /usr/bin/arm-linux-gnueabi-gcc

    -) Download the Kernel sources from
    http://www.huaweidevice.com/worldwide/technicaIndex.do?method=gotoProductSupport&productId=3834&tb=1

    -) Unpack Kernel and cd into it.

    -) Get the original Kernel config from your device like this:
    Code: 
    adb pull /proc/config.gz
    then unpack it into the Kernel directory and rename it to ".config"

    If you want, you can adjust it with any texteditor, or by calling "make menuconfig" but for this you should first export the variables below so that make knows you want to build for the arm platform, not for x86

    -) finally build the Kernel like this:
    Code: 
    export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-linux-gnueabi-
make

    -) I found the easiest way to deploy the built kernel is the following:
    install the package abootimg
    Code: 
    sudo apt-get install abootimg

    and then make a copy of some preexisting boot.img (look at your device either with the pink screen mode or with certain custom ROMs that are not built as "production build" you can directly see the folder /.cust_backup/image

    warning, this copy will be directly edited, so be sure to have another copy of the same image somewhere else.
    Okey, now replace the path to your built kernel and the path to your boot.img and run:
    Code: 
    abootimg -u path/to/bootimg/boot.img -k /path/to/kernel/arch/arm/boot/zImage

    thats it, this replaces the kernel from this boot.img with your newly built kernel and can be written to folder /.cust_backup/image (be sure to keep a backup of your previous boot.img) and then reboot your device - voilà!

    EDIT: This deployment method does not include deployment of kernel modules, for that you need more complex deployment methods as for example described here:
    http://forum.xda-developers.com/showthread.php?t=916198

    For making a custom kernel just adjust the sources between download/unpacking and building :)

    EDIT: For the Guide scroll down to post number 4
    http://forum.xda-developers.com/showpost.php?p=23916656&postcount=4

    Hi there!

    I would like to get started with building kernels for my newly bought Huawei Honour U8860

    My motivation comes from the desire to have this app running on my device, which apparently needs some kernel patches to be applied, since I'm missing the devicefiles called /dev/voc* --> http://code.google.com/p/rvoix/
    The Kernel patches can be found here: http://code.google.com/p/rvoix/source/browse/#svn/branches/snapdragon/kernel

    What I found on my own is this:
    http://source.android.com/source/building-kernels.html

    But I have no idea what kernel to start from, the list of devices they have over there
    http://source.android.com/source/building-devices.html
    have names like: "maguro, panda, wingray, crespo, passion, sapphire, dream" and I have no idea what they mean, except for those few names that are explained on the same page.

    I am currently running a rooted Android 4.0.3 that I gained by following this guide:
    http://forum.xda-developers.com/showpost.php?p=22688341&postcount=53

    I would really apreciate any help anyone can give me! Thanks in advance

    EDIT: okey!! I found a download from huawei here
    http://www.huaweidevice.com/worldwide/technicaIndex.do?method=gotoProductSupport&productId=3834
    Thats called: "open source-kernel-3.0.8-U8860-IcecreamSandwich"
    http://www.huaweidevice.com/worldwi...=toDownloadFile&flay=software&softid=NDQwNDc=
    So I will try to work with this and get it build and deployed on my device. Thats gonna be a lot of work, will report back when I finished or aborted my mission frustrated.

    EDIT2:
    Okey, this is really a hard thing if you don't know what you're doing, like me... I think I'm gonna give up, all these config options (i stopped reading after the first 50 and just hold down the enter key for agreeing to the default), and in the end some strange errors:
    ..._kernel/arch/arm/include/asm/irqflags.h:11:5: warning: "__LINUX_ARM_ARCH__" is not defined
    error, forbidden warning: irqflags.h:11
    make[1]: *** [arch/arm/kernel/asm-offsets.s] Fehler 1
    make: *** [prepare0] Fehler 2

    About my initial motivation for compiling myself a kernel:
    There are a lot of call recording apps, though most only record from the microphone, and therefore only record a weak shadow of the other side of the conversation.

    For the moment I stick with this one:
    https://play.google.com/store/apps/details?id=androidlab.allcall

    When I tested it with a few testcalls, it seemed to me that the other side is also recorded, even though it gave me an error that it can't record the other side. However, now after a few days real usage I'm not so sure if it truely records the other side, or if this is only this shadow that comes in through the mic. It is hardly understandable in the recordings most of the times now.

    So this alternative app is at least an interim solution, but I still wan't to get myself a kernel compiled, and once done try to apply or adept the kernel patches from http://code.google.com/p/rvoix/ to this kernel

    Okey. So about building this kernel from huawei. From googling a bit I learned that this error
    Code: 
    ...arch/arm/include/asm/irqflags.h:11:5: warning: "__LINUX_ARM_ARCH__" is not defined
error, forbidden warning: irqflags.h:11
make[1]: *** [arch/arm/kernel/asm-offsets.s] Fehler 1
make: *** [prepare0] Fehler 2
    stems from problems with the toolchain used for building

    But first let me document a bit how I got this far:

    1.) download the kernel sources from:
    http://www.huaweidevice.com/worldwide/technicaIndex.do?method=gotoProductSupport&productId=3834&tb=0

    2.) get the kernel config from the device, by connecting it via usb, turning on the usb debugging on it and then using
    Code: 
    adb pull /proc/config.gz
    to fetch it. unpack it and put it into the same directory as the extracted kernel, but by the name ".config"
    --> learned this one from http://mjanja.co.ke/2011/06/compiling-custom-kernels-on-the-huawei-u8150/

    3.) Download and extract an android NDK

    4.) open a terminal and set up a few environment variables:
    Code: 
    export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=/path_where_i_extracted/android-ndk-r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-

    5.) simply call make. I also tried to run "make menuconfig" before running make, since a few sources stated it would be neccecary, but that didn't change the error I got.

    This guy here states that 7b is not good and 5c is the way to go, but this error kept the same.
    http://www.android-hilfe.de/root-ha...deos-x3/172743-kernel-selbst-kompilieren.html

    So I looked into ubuntu and found that there is also an arm gcc toolchain, and got it by simply installing this package:
    Code: 
    sudo apt-get install gcc-arm-linux-gnueabi

    and since the system puts its stuff all into the proper path so you can use it easily just call
    Code: 
    export CROSS_COMPILE=arm-linux-gnueabi-

    and afterwards again "make" and I got a new and different output:

    But well. I also can't make a lot of meaning out of this... So still looking for help on how to get myself a kernel compiled

    Okey, big progress! I found this string somewhere:
    Linux version 3.0.8-perf ([email protected]) (gcc version 4.4.3 (GCC))
    #1 PREEMPT Tue Mar 6 17:48:17 CST 2012

    This told me, that this kernel can be built with gcc version 4.4

    I looked into ubuntu, and found this version is also available in the repository. So I removed the standard version which is 4.6 and installed 4.4 --> now the kernel seems to build. I'm gonna leave the PC runnign over night and look in the morning at the results.

    If someone wants to redo my steps:
    the ubuntu package you need is "gcc-4.4-arm-linux-gnueabi"
    be sure to remove all other arm gcc packages, and then set a link:
    Code: 
    ln /usr/bin/arm-linux-gnueabi-gcc-4.4 /usr/bin/arm-linux-gnueabi-gcc

    EDIT: so the "make" command finished without any error messages. So next step is to find out how to pack the builded kernel into a boot.img to deploy it to the device.
