[Q] Compiling a simple kernel module for N1 - Nexus One Q&A, Help & Troubleshooting

[Q] Compiling a simple kernel module for N1 - Nexus One Q&A, Help & Troubleshooting

I followed the instructions listed here to compile the kernel from the source and was successful. Next, I saw some instructions here on how to compile our own loadable kernel modules:
Code:
First we must retrieve and copy the kernel config from our device.
$ cd /path/to/android-sdk/tools
$ ./adk pull /proc/config.gz
$ gunzip ./config.gz
$ cp config /path/to/kernel/.config
Next we have to prepare our kernel source for our module.
$ cd /path/to/kernel
$ make ARCH=arm CROSS_COMPILE=/path/to/android-ndk/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin/arm-eabi- modules_prepare
PREPARING YOUR MODULE FOR COMPILATION
We need to create a Makefile to cross-compile our kernel module. The contents of your Makefile should be similar to the following:
obj-m := modulename.o
KDIR := /path/to/kernel
PWD := $(shell pwd)
CCPATH := /path/to/android-ndk/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin
default:
$(MAKE) ARCH=arm CROSS_COMPILE=$(CCPATH)/arm-eabi- -C $(KDIR) M=$(PWD) modules
COMPILING AND INSTALLING YOUR MODULE
$ cd /path/to/module/src
$ make
$ cd /path/to/android-sdk/tools/
$ ./adb push /path/to/module/src/modulename.ko /sdcard/modulename.ko
RUNNING YOUR MODULE
$ cd /path/to/android-sdk/
$ ./adb shell
$ su
# insmod /sdcard/modulename.ko
When I try executing:
Code:
make ARCH=arm CROSS_COMPILE=/path/to/android-ndk/toolchains/arm-eabi-4.4.0/prebuilt/linux-x86/bin/arm-eabi- modules_prepare
I get an error:
Code:
make: *** No rule to make target `modules_prepare`. Stop.
Can someone please tell me if I am missing something here?

The topic is old but the reply may be useful for other people:
this is the tipical issue when is missing the .config file which is a defconfig to be taken from /kernelfolder/arch/arm/configs

[Q] How to make a ROM?

Hello everyone.
Now I know this question has been posted before but I didn't get enough help from that so...
Let me explain what I've done...
I appreciate all of the work that the Devs have done, however, I would
love to help them.
I decided to try and build my own ROM. Unfortunately, I'm getting stuck and
am not sure how to proceed.
That is why I am here. I was hoping the wise devs here on XDA could help me
along this path I'm taking.
Here's my goal.
Build a 2.1 rom from source. No modifications at first.
Run this on an Emulator to see how it runs.
Then run it on my phone.
Here are the steps I've taken:
- Installed Ubuntu
- Installed jdk1.5
#sudo gedit /etc/apt/sources.list
-Add these lines
deb http://archive.ubuntu.com/ubuntu/ jaunty multiverse
deb-src http://archive.ubuntu.com/ubuntu/ jaunty multiverse
deb http://archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
deb-src http://archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
-Save and exit
#sudo apt-get update
#sudo apt-get install sun-java5-jdk
#sudo update-java-alternatives -s java-1.5.0-sun
-Install the dev tools
# sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev valgrind
# cd ~
# mkdir bin
# curl xxxx://android.git.kernel.org/repo >~/bin/repo
# chmod a+x ~/bin/repo
-Get the android source
# cd ~
# mkdir mydroid
# cd mydroid
# repo init -u git://android.git.kernel.org/platform/manifest.git -b android-2.1_r2
# repo sync
-Download the samsung files from opensource.samsung.com
-Search for SGH-I897 and download the tar
# cd ~/Downloads
# mkdir samsung_files
# mv SGH-I897_OpenSource.tar.gz samsung_files/
# cd samsung_files
# tar xzvf SGH-I897_OpenSource.tar.gz
# tar xvf Platform.tar
-Merge the files together
# cd ~/Downloads/samsung_files/Captivate_eclair
# rsync -a --stats --progress dalvik/ ~/mydroid/dalvik/
# rsync -a --stats --progress external/ ~/mydroid/external/
# rsync -a --stats --progress prebuilt/ ~/mydroid/prebuilt/
# rsync -a --stats --progress vendor/ ~/mydroid/vendor/
-Modify the BoardConfig.mk
# sudo gedit ~/mydroid/build/target/board/generic/BoardConfig.mk
-Add these lines
BOARD_HAVE_BLUETOOTH := true
BT_USE_BTL_IF := true
BT_ALT_STACK := true
BRCM_BTL_INCLUDE_A2DP := true
BRCM_BT_USE_BTL_IF := true
-Compile the ROM
# cd ~/mydroid
# make update-api
# make
Now I browsed through the out directory after the Make was complete
and found some .img files:
ramdisk.img
system.img
userdata.img
userdata-qemu.img
I don't have anything for a Kernel and am confused as to how to
take these files and make a .zip that I can flash through CWM
Any direction from here would be greatly appreciated.
i.e.
How to make this run on an emulator.
How to turn this in to a .zip to flash through CWM
Also some tips on modifying the ROM would be nice

i always assumed it was some sort of magic or wizardry.....but all that **** you just said sounds pretty important, too.

[Guide] A beginners guide to building and modifying a nexus 4 kernel from source

A beginners guide to building and modifying a nexus 4 lollipop* kernel from source.
*currently 5.0.1Disclaimer
I am not a developer, nor am I an expert. All the information in here I have gleaned from other sources, credited where possible, so it may not be correct and almost certainly isn't the 'best' way to do things. But it works for me. I hope it works for you but there's no guarantee. Use at your own risk
Assumptions
You have access to a computer running Ubuntu - other distros will probably work but this is the one I'm using. You'll need a basic understanding of the Linux command line including, but not limited to, ls, cp, cd, mkdir, make, ~, sudo, nano and so on.
You'll need to know how to use adb & fastboot to copy stuff into and out of your Nexus 4
A basic undersanding of Git is REALLY helpful if you want to modify your kernel. You'll be able to get by using the comands listed but you really need to have a basic understanding of what Git does if you're going to proceed.
CONTENTS
Initialise your build environment
Downloading the sources
Toolchain
Building
Creating a boot.img
A bit more about Git
Modifying kernels (how I got DT2W working)
Making a flashable zip
Initialise your build envronment
The information for this stage came from: here
I installed Ubuntu 14.04.1 LTS from a scratch. I used VM ware on a Windows laptop but any Linux environment can probably be made to work. So, to start, do an update just to be sure, then install the packages you'll need.
Code:
# sudo apt-get update
# sudo apt-get install bison g++-multilib git gperf libxml2-utils
# sudo apt-get install libncurses5-dev:i386
# sudo apt-get install lib32ncurses5-dev
# sudo apt-get install build-essential kernel-package
Downloads
Most of the really helpful information I've used came from here
I've updated the information slightly and changed the device from Flo to Mako but Pete's page is well worth reading for more background information than I've included here.
To download the source into a 'kernel' folder
Code:
# mkdir ~/android
# cd ~/android/
# git clone https://android.googlesource.com/kernel/msm.git kernel
# cd kernel/
# git branch -a
will show you all the current branches of Mako kernels, choose the one you want and checkout that one.
Code:
# git checkout android-msm-mako-3.4-lollipop-release
Now you need to find out exactly which kernel to build. The 'official' method is here
but that involves a significant download for just a few bytes so I suggest you use the following trick. Go to the pre-built kernel you want to copy here
and you wll see the first line after the header is:-
"16e203d lowmemorykiller: enhance debug information"
You need to make a note of the first seven characters, in this case 16e203d.
Next you need to use Git to create a new branch for our specific kernel. I've called it 'android-lollipop-release'.
Code:
# git checkout -b android-lollipop-release 16e203d
This will extract the source for the kernel we're going to build.
Toolchain
I'm using the stock toolchain (thanks @zaclimon) but will add an alternative suggested by @aviz1911 as time allows.
I'm going to install the toolchain in /usr/local/share but there are other places you could sensibly put it.
Code:
# cd /usr/local/share
sudo git clone [url]https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7[/url]
Export the path to the toolchain and check it works. Note these exports only work for the current session, if you want to add permanently put it in your .bashrc or .profile
Code:
# export PATH=$PATH:/usr/local/share/arm-eabi-4.7/bin
# cd ~
Test it works with
Code:
# arm-eabi-gcc --version
Now you need to tell the system we want to cross compile.
Code:
# export ARCH=arm
# export SUBARCH=arm
# export CROSS_COMPILE=arm-eabi-
Building
Now you're ready to start.
Code:
#cd ~/android/kernel
# make mako_defconfig
You'll get some warnings like this which you can ignore
warning: (ARCH_MSM_KRAITMP && ARCH_MSM_CORTEX_A5) selects HAVE_HW_BRKPT_RESERVED_RW_ACCESS which has unmet direct dependencies (HAVE_HW_BREAKPOINT)
Code:
# make menuconfig
this is where you can make some changes if you like, we're going to change just the name. Choose General Setup ---> then select
(-perf) Local version - append to kernel release
and change perf to anything you like, I'll use dt2w
Save and exit
Code:
# make -j2
where 2 is twice the number of cores on your machine - there's just one processor on my VM but could be many more on yours. It takes more than half an hour on my machine. Then you should see
Code:
Kernel: arch/arm/boot/zImage is ready
Ta Daaaaa - you have built a kernel - now you need to pack it for testing on your phone.
Creating a boot.img
Again I'm going to use Pete's blog post as my guide but omit some details and just get the job done. I'm not going to explain all the steps, you'll have to investigate yourself if you want to understand more.
Code:
# cd ~/android
# git clone https://github.com/pbatard/bootimg-tools.git bootimg-tools
# cd bootimg-tools/libmincrypt/
# gcc -c *.c -I../include
# # cd ../mkbootimg
# gcc mkbootimg.c -o mkbootimg -I../include ../libmincrypt/libmincrypt.a
# sudo cp mkbootimg /usr/local/bin/
# gcc -o unmkbootimg unmkbootimg.c
# sudo cp unmkbootimg /usr/local/bin/
You need an original boot img to copy so you can insert your new kernel into it. Download the factory image.
Code:
# mkdir ~/android/boot
# cd ~/android/boot
# wget https://dl.google.com/dl/android/aosp/occam-lrx22c-factory-86c04af6.tgz
# tar -xvf occam-lrx22c-factory-86c04af6.tgz
# cd occam-lrx22c/
# unzip occam-lrx22c-factory-86c04af6.zip
# cp boot.img ../
# cd ~/android/boot
Now it's time to unpack the original boot image. unmkbooting will tell you all the parameters you need to repack the boot image with your new kernel inside.
Code:
# unmkbootimg -i boot.img
kernel written to 'kernel' (6009416 bytes)
ramdisk written to 'ramdisk.cpio.gz' (490557 bytes)
To rebuild this boot image, you can use the command:
mkbootimg --base 0 --pagesize 2048 --kernel_offset 0x80208000 --ramdisk_offset 0x81800000 --second_offset 0x81100000 --tags_offset 0x80200100 --cmdline 'console=ttyHSL0,115200,n8 androidboot.hardware=mako lpj=67677 user_debug=31' --kernel kernel --ramdisk ramdisk.cpio.gz -o boot.img
Code:
# cp ~/android/kernel/arch/arm/boot/zImage ~/android/boot/
Repack your new boot image with your new kernel using the information from unmkbootimg
Code:
mkbootimg --base 0 --pagesize 2048 --kernel_offset 0x80208000 --ramdisk_offset 0x81800000 --second_offset 0x81100000 --tags_offset 0x80200100 --cmdline 'console=ttyHSL0,115200,n8 androidboot.hardware=mako lpj=67677 user_debug=31' --kernel zImage --ramdisk ramdisk.cpio.gz -o new_boot.img
Nore that kernel has been changed to zImage and output file has been changed new_boot.img Now it's time to test your new_boot.img by rebooting your phone into bootloader and reboot with the new img.
DO NOT FLASH THE NEW IMAGE.
fastboot boot new_boot.img NOT fastboot flash boot new_boot.img
If all has gone well your phone will now boot with your new kernel. If something has gone wrong just reboot the phone and you'll be back to where you started. If it has all worked then you can flash the new boot image and use that.

A bit more about Git
If like me, you know nothing about Git, then this bit of the guide is for you. If you have basic understanding this will be too simple for you and you'll have to skip this bit and look elsewhere. If you have a basic understanding of any version control software you won't need this either as the necessary commands to complete the next step will be self explanatory.
Jump to the next stage here
Git is a version control system. To understand what it does at a most basic level follow these steps
Code:
# mkdir git_test
# cd git_test
# git init
Tell git who you are. You don't need the inverted commas, just an email address and a name. Keep this information for when/if you open a Github account.
Code:
# git config --global user.email "[email protected]"
# git config --global user.name "Your Name"
create a text file called 'text' with a single line of text that says "This is the first line"
add this file to your git
Code:
# git add text
commit the change with a message
Code:
git commit -m "first line"
create a new branch (checkout -b both creates and makes the new branch current)
Code:
git checkout -b newbranch
edit the 'text' file by adding another line "this is the second line"
add and commit the change to git
Code:
# git add text
# git commit -m "second line"
Then examine the text file, as you might expect it looks like this
Code:
# cat text
this the first line
this is the second line
but if we now go back to the master branch and checkout THE SAME file, we get a different result
Code:
# git checkout master
cat text
this the first line
The second line is not present because it was only added to the 'newbranch' branch. This, it appears to me is the essence of git, it changes files depending on which branch you're viewing them from.
Now we're going to look at how we can use git to extract files from someone else's repository in order to get the files we want for our needs.
There are loads of guides that help you to learn more, I found this video particularly helpful.

Modifying kernels (how I got DT2W working)
Edit:- It's going to be a while before I complete this section as although I managed to build a working kernel I'm pretty sure I didn't do it the 'right' way so I'm reading the Git Pro book.
Will be back later. .. . .

Awesome guide dude. This will surely help a lot of people

Nice
Nice guide, wish you'd have written it a week earlier
Anyways, what i'd really like to know, is how to patch the Linux version properly, because my attempts lead to break the kernel in the process. Didn't get beyond 3.4.11 :/
Hope you can help me out there, buddy.

How to create a zip ?
I have been looking into this and created a kernel a few days ago. But i want to share it.
For that ill have to create a zip. I have searched for it. I think its done using anykernel template.
The issuse is can i use the certificates in the meta-inf folder and the update-binary that is 4 years old ?
Or should i just unzip a kernel , modify the script and place my boot.img. 
 @aviz1911

Unzipping and re zipping is pretty easy, I'd do that.

@Nicknoxx How's the reading up on git going? Any tips on enabling dt2w would be much appreciated. I've been trying but can't seem to get it to work
I'm really new at the Kernel stuff and just wanted to build stock with dt2w as my first project.
Thanks for the first part of the guide

Wow nice guide sir, i'll try it later

Great Guide!
Thanks Mate!!

what all lines or links should i have to modify if i am building kernel for my device oneplus one lollipop ?
 @Nicknoxx

Also @Nicknoxx one can use the -b argument with git while cloning so git just downloads a single branch of the kernel source, this'll save bandwidth and time to some extent
Like
git clone https://android.googlesource.com/kernel/msm.git -bx kernel
Replace x with desired branch name

Nice guide. I ad it to my collection. I mis the part about building the modules. For wifi and so on. I think the command is "make modules"
Maby ad some info about updating a kernel. ICS to JB. KK to LP and sow on.
How about the command to clean after building?

Executing the make -j# command automatically builds your modules along with the Zimage, you'll just need to read last few lines in terminal to know the modules and where they reside

Hi guys,
How i can implement this mod/patch in my kernel??

[GUIDE] Android One (Sprout) Making Kernel's or ROM's in Simple Way [NOOB FRIENDLY]

Post is Influenced from @Anik_khan Kernel Post to make Procedure More Simple for Us All.
So Don't BE Shocked to see Things
Prerequisites:
Ubuntu 14.04 Trusty Tahr 64 Bit. (Can be on VirtualBox or Full Install Your Wish.)
RAM Minimum:2GB Recommended:4GB
Around 100GB Space for ROM’s. (Kernels can use upto 1GB.)
Unlimited (Fast) LAN Connection.
More RAM, or faster CPU, or SSD will speed up the process.
A Brain (Most Important of All :v)
At the starting of the post I have linked a script by @akhilnarang which if run will automatically install all these programs for lazy people.
If you not interested to do all procedure from below just use the script. Simply it will automatically configure the build environment.
NOTE-------- some of these packages may already be on your machine. Obviously, if you complete a step and you have one of these installed, the machine simply will not do anything. So...it will not hurt anything. Some of the packages are different from Ubuntu 12.04 and 13.04 (use these packages for Ubuntu 14.04 as many of the old ones have obsoleted - these are new replacements).
So if you set up your pc with Ubuntu we are good to go.
All code will be in code boxes like this:
Code:
$
means you have to run that command in the terminal (don't type the $).
All commands with sudo, gksudo, or gksu means it requires root permission.
It will ask for password.
Once you type, then in that terminal session it will not ask you for a few minutes again.
Any time you make changes to .bashrc or .profile file, make sure to run
Code:
$ source ~/.bashrc
$ source ~/.profile
Or exit and open new terminal else the changes will not take place
Setting Up Build Environment
Method 1:
So if you not interested in doing below all steps then simply use this script by my friend @akhilnarang
Open terminal and type:
Code:
$ sudo apt-get install git-core
then do
Code:
$ git clone https://github.com/akhilnarang/scripts.git
$ cd scripts
$ . build-environment-setup.sh
This script will install all required packages
Method 2:
1)Installing Java JDK
Open terminal (CTRL + ALT + T)
Then execute the following commands in terminal one by one:
Download & install java
Code:
$ sudo apt-get update && sudo apt-get install openjdk-7-jdk openjdk-7-jre
CHECK if java properly installed or not
Code:
$ java -version
If you get output like
Code:
Code:
java version "1.7.0_79" or anything higher(in my case)
on the first line then all is good
Now JDK is configured!
Note: Only for Ubuntu 14.04 or higher
2)Installing Required Packages
Open Terminal
Now execute this command:
Note: This will take some time, has to download about 500MB or so of packages
Code:
$ sudo apt-get update && sudo apt-get install git-core python gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.8-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev openjdk-7-jdk pngcrush schedtool \
libxml2 libxml2-utils xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline-gplv2-dev gcc-multilib liblz4-* android-tools-adb android-tools-fastboot ccache
3)Installing Android SDK
Download the SDK from here!
Accept Terms & download 64 bit.
Extract in your home directory & rename extracted folder "android-sdk".
Now, execute these commands in terminal:
Code:
$ cd ~/android-sdk/tools/
$ ./android sdk
At this point the SDK should come up and you will need to download at least all the tools and all the extras files (at least to 4.0, so select them and install them.When it finishes downloading & installing everything you have to run this command in ANOTHER TERMINAL:
Code:
$ sudo apt-get install gksudo
$ gksu gedit .bashrc
And you need to add at the end of it your SDK paths these three lines (copy and paste them):
Code:
export PATH=~/android-sdk/tools:$PATH
export PATH=~/android-sdk/platform-tools:$PATH
export PATH=~/bin:$PATH
Save and close the file, then close terminal, or
Code:
source ~/.bashrc
Find your .profile file and add this at the bottom of the file
Code:
PATH="$HOME/android-sdk/tools:$HOME/android-sdk/plartform-tools:$PATH"
SDK is configured.
4)Configuring USB Access
Now we need to set permissions so that our USB ports can detect our android devices
Type in the following commands, it will download a file with the permissions, give it permission to execute, and restart the service.
Code:
$ sudo curl --create-dirs -L -o /etc/udev/rules.d/51-android.rules -O -L https://raw.githubusercontent.com/snowdream/51-android/master/51-android.rules
$ sudo chmod 644 /etc/udev/rules.d/51-android.rules
$ sudo chown root. /etc/udev/rules.d/51-android.rules
$ sudo service udev restart
$ sudo killall adb
ADB & Fastboot are configured
5)Installing Repo Package
Open terminal and type:
Code:
$ mkdir ~/bin
$ PATH=~/bin:$PATH
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
6)Configure Git
Open terminal and type:
Code:
$ git config --global user.email ""
$ git config --global user.name ""
Git is configured.
7)Configure ccache
Open terminal and type:
Code:
$ gksu gedit ~/.bashrc
Enter these lines
Code:
export USE_CCACHE=1
export CCACHE_DIR=~/.ccache
Save & close
Open terminal & execute:
Code:
$ source .bashrc
$ ccache -M 50G
I usually use 50 gigs. You can use more if you have more space, or build for many devices
Congrats
YOUR BUILD ENVIROMENT IS NOW SETUP .

[Guide] Build ASOP from source with Ubuntu 14.04 64bit

First let me give you some background information before we start. I know there are guides out there but I found them all to be incomplete either missing a step here or there that is why I am posting this guide. After a lot of trial and error I tried to make the process as simple as it can be. This guide is for Ubuntu 14.04 64bit Desktop or Server version. This guide might work on other distros but I cannot guarantee it. This guide is designed to build the AOSP rom from Google source jellybean to lollipop. I highly recommend doing this on a remote server, like a vps or dedicated box. This guide is for root users if your not root then you may need to use "sudo" on many of the commands.
## Disclaimer I am not responsible for anything that happens to your device this is a guide only. I am not a master developer or linux guru if you have questions I will try to answer them best I can. ##
Most important command if your on a remote machine this will keep the process going if you get disconnected.

## Establishing a Build Environment ##
# Java Install
apt-get update
apt-get upgrade (upgrades all the packages installed on system that have updates)
apt-get install openjdk-7-jdk (Lollipop)
apt-get install openjdk-6-jdk (KitKat or older)
# Optionally, update the default Java version by running:
update-alternatives --config java
update-alternatives --config javac
# Check if JAVA is Installed
java -version
# You should see something like this depending on the version you installed.
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)
# Installing required packages
apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip python-networkx libswitch-perl schedtool
## Downloading the Source ##
# To install Repo:
Make sure you have a bin/ directory in your home directory and that it is included in your path:
mkdir ~/bin
PATH=~/bin:$PATH
# Download the Repo tool and ensure that it is executable:
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo
# Initializing a Repo client
# After installing Repo, set up your client to access the Android source repository:
# Create an empty directory to hold your working files. Give it any name you like:
mkdir WORK
cd WORK
git config --global user.email "useyourrealemail"
git config --global user.name "usearealname"
repo init -u https://android.googlesource.com/platform/manifest
To check out a branch other than "master", specify it with -b. For a list of branches, see Source Code Tags and Builds.
repo init -u https://android.googlesource.com/platform/manifest -b android-5.1.1_r1 ( To build only Lollipop. I suggest this option for most)
## Downloading the Android Source Tree ##
# To pull down the Android source tree to your working directory from the repositories as specified in the default manifest, run
repo sync -j4
# The Android source files will be located in your working directory under their project names. This takes anywhere from 15 minutes to a few hours depending on your internet connection. (Thats why I recommend building on a remote machine)
## Binaries ##
# Extracting the proprietary binaries
# Each set of binaries comes as a self-extracting script in a compressed archive. After uncompressing each archive, run the included self-extracting script from the root of the source tree, confirm that you agree to the terms of the enclosed license agreement, and the binaries and their matching makefiles will get installed in the vendor/ hierarchy of the source tree.

Im not sure you will have to search the forums or google.

AOSP built just fine for me with OpenJDK... and Google's documentation page seems to say OpenJDK is the right JDK for building under Ubuntu. So the build script seems to be incorrect. I got past the error you reported by tweaking the check.
In build/core/main.mk line 195 (the line which ends with "grep -i openjdk),)") I changed "ifneq" to "ifeq" and then it built fine for me. Probably not the right change, but it let me proceed. I was building aosp6 on Ubuntu 15.10 with java-8-openjdk-64.

I mainly got the error when building diffrent versions of 4.1.2 to 4.4.4. I never got the error when doing lollipop so I included the oracle fix just to be safe incase others incounter the same problem. Thank you for the possible fix I will be testing it out soon.

[KERNEL] {WIP} Port Lollipop 5.1 Source -> AOSP Marshmallow 6.0 [Device_a32e]

Currently Building Bootable Android 5.1 Kernel From HTC DEV Source.
(THIS IS THE STOCK 5.0.1 / RUU Version = 1.23.1550.3 CL637541 RELEASE-KEYS)
Linux version 3.10.49-perf-g26c2269 ([email protected]) (gcc version 4.7 (GCC) ) #2 SMP PREEMPT Sat Oct 31 02:35:36 CST 2015
This has been compiled and will boot on the device.
NOTE: WI-FI IS NOW WORKING
NOTE: DT Blobs broken:Fixed by using Blobs pulled from the device.}
WORK IN PROGRESS !!
Currently HTC has not released the Kernel Source for Marshmallow 6.0.1.
Solution: Port the 5.0.1 HTC Source by merging with AOSP device/lge/bullhead-kernel
Current Status:
WORKING KERNEL NO CHANGES FROM STOCK
Will Build for other Devices upon request.
Anyone who wishes to contribute to this project would be appreciated.
I'm in the process of setting up the GIT and the project on XDA.

Setting Up To Test 3.10.49-perf-g26c2269 Kernel Build
First I would like to mention that a full LINUX Development Environment is required to perform most of these tasks. If you don't have the development environment set up then please do the necessary research.
To test YOUR development environment and the HTC-DEV Kernel Source it is necessary to perform the following steps.
1 ) If you are currently running Marshmallow 6.0.1 you will need to downgrade the device to Lollipop 5.0.1 using the RUU. Please note that the Lollipop RUU is no longer available on the HTC-DEV site. Don't worry we will be going back to Marshmallow but need to test in lollipop first.
Please see the following thread for instructions on downgrading the HTC Desire 626s.
http://forum.xda-developers.com/desire-626/development/metropcs-htc-626s-to-lollipop-t3460391
:good:
2) Download the Kernel Source Code from the HTC-DEV Site.
http://www.htcdev.com/devcenter/downloads
If you use the filter for device and select desire 626s you will see only the 626s kernel sources.
The device I have = HTC Desire 626s (a32eul) " Carrier Metro-PCS"
The Kernel Source I am using.
Device= Desire626s Carrier=HTC Region= Gen Unlock Type=CRC
Kernel Version=3.10.49 Android Version=v5.1 Size=548 MB Description=1.06.617.6

Backup the device boot.img & Unpack / Split the kernel + ramdisk + dt.img.
Now we are all on the same page. " Same Setup Fresh Install "
Lets get down to business.
I'm going to go through the steps that I use. If you plan to work along with this project I recommend that you keep the same directory structure that I have. This way all the commands I give you will work. You may wish to change the directory structure but if you do.... remember you will need to adjust the commands accordingly.
So from a brand new fresh install.
#1 install twrp recovery
#2 install supersu
#3 Open supersu on phone
#4 Make sure usb debugging is turned on ect. ect. ect.
#5 Lets get the boot.img from the device.
Connect the device to the computer
From this point forward all commands are executed in the Linux terminal shell.
Code:
adb shell
Code:
su
Copy boot partition to the external sd card.
Code:
dd if=/dev/block/bootdevice/by-name/boot of=sdcard2/Boot.img
Pull the boot.img to the computer.
If still in adb shell exit out.
Code:
exit
exit
adb pull /sdcard2/Boot.img
#6 Setup some directories and move the boot.img into our project.
Code:
mkdir ~/a32e-kernel-build/
mkdir ~/a32e-kernel-build/Device-Files/
mkdir ~/a32e-kernel-build/Device-Files/Boot
mkdir ~/a32e-kernel-build/Tools
mkdir ~/a32e-kernel-build/Tools/AIK-Linux/
mv Boot.img ~/a32e-kernel-build/Device-Files/Boot
cd ~/a32e-kernel-build/Tools/AIK-Linux/
cp ~/a32e-kernel-build/Device-Files/Boot/Boot.img ~/a32e-kernel-build/Tools/AIK-Linux/
#7 We need AIK-Linux boot tools. Download them from the link below.
http://forum.xda-developers.com/showthread.php?t=2073775
Please do use these bootimg tools. You might have others but AIK-Linux unpacks and repacks the image files as "ROOT".
Using other tools or not unpacking / repacking as ROOT will cause a bootloop specifically in Marshmallow even if the boot.img is good.
Code:
mv ~/Downloads/AIK-Linux-v2.4-ALL.tar.gz ~/a32e-kernel-build/Tools/AIK-Linux
tar -xvzf ~/a32e-kernel-build/Tools/AIK-Linux/AIK-Linux-v2.4-ALL.tar.gz
rm -f ~/a32e-kernel-build/Tools/AIK-Linux/AIK-Linux-v2.4-ALL.tar.gz
mv -v ~/a32e-kernel-build/Tools/AIK-Linux/AIK-Linux/* ~/a32e-kernel-build/Tools/AIK-Linux/
rm -d ~/a32e-kernel-build/Tools/AIK-Linux/AIK-Linux
Ok I know ????????
You want to know what we need the boot image for anyway !!
The a32e_defconfig file that comes with the HTC-DEV source code is not the exact configuration that HTC used when they built the kernel.
We want to start out with the same configuration RIGHT!!
Yes we do...... and after we have a verified working Kernel.......then we can start making changes.
In a nutshell /proc/config.gz will not work to pull the existing configuration. HTC did not enable that option. Lucky for us there is another way to generate the configuration file & that's reason #1 that we need the boot.img. There is another reason but we will get to that later. ( Other than having a Backup of the boot.img LOL. )
#8 Unpack the boot.img
Code:
sudo ./unpackimg.sh Boot.img
Make sure you use "sudo" it is nessessary.
The output should be
~/a32e-kernel-build/Tools/AIK-Linux$ sudo ./unpackimg.sh Boot.img

Getting Running Kernel Configuration
#1 Lets get the current running Kernel Version
Code:
cd ~/a32e-kernel-build/Device-Files/Boot/
Code:
dd if=kernel bs=1 skip=$(LC_ALL=C grep -a -b -o $'\x1f\x8b\x08\x00\x00\x00\x00\x00' kernel | cut -d ':' -f 1) | zgrep -a 'Linux version'
My output is as follows.
Linux version 3.10.49-perf-g26c2269 ([email protected]) (gcc version 4.7 (GCC) ) #2 SMP PREEMPT Sat Oct 31 02:35:36 CST 2015

Hopefully you see or know why this is important to us.
In order for our new kernel to load and not reject existing modules the version of the new kernel must match.
Linux version 3.10.49-perf-g26c2269
And also the 26c2269 is the number we need,
to match the exact commit of the source code that this specific kernel was built upon.
In theory when we checkout a branch and that would be used as part of the tag.
Right now the most important thing to us is the "-perf"
And the ".-g26c2269"
We will need those soon.
Now lets get that .config / a32e_defconfig file.
Wayy back in step number 2 of the 1st post you were supposed to get the HTC-DEV Kernel source.
If you didn't it's time we need it now.
http://www.htcdev.com/devcenter/downloads
When you get to the HTC-DEV download page just filter by device and select desire 626s.
#1 Set Up Basic HTC-DEV Source Directory Structure
Code:
cd
mkdir ~/android
mkdir ~/android/device
mkdir ~/android/device/a32e
mkdir ~/android/device/a32e/platform
#2 Setup the Kernel Source
Code:
mv ~/Downloads/a32eul-3.10.49-perf-ga4d7327.zip ~/android/device/a32e/a32eul-3.10.49-perf-ga4d7327.zip
unzip ~/android/device/a32e/a32eul-3.10.49-perf-ga4d7327.zip -d ~/android/device/a32e/
rm -f ~/android/device/a32e/a32eul-3.10.49-perf-ga4d7327.zip
cd ~/android/device/a32e/
tar -xvzf ~/android/device/a32e/248_kernel_a32eul-3.10.49-perf-ga4d7327.tar.gz
rm ~/android/device/a32e/248_kernel_a32eul-3.10.49-perf-ga4d7327.tar.gz
mv -v ~/android/device/a32e/248_kernel_a32eul-3.10.49-perf-ga4d7327/* ~/android/device/a32e/
rm -rf ~/android/device/a32e/248_kernel_a32eul-3.10.49-perf-ga4d7327
mv ~/android/device/a32e/platform.tar.gz ~/android/device/a32e/platform/
#3 Pull the config from the kernel
Code:
cd ~/android/device/a32e/scripts/
./extract-ikconfig ~/a32e-kernel-build/Device-Files/Boot/Boot.img-zImage > Big-Country_defconfig
mv -f Big-Country_defconfig ~/android/device/a32e/arch/arm/configs
mkdir ~/a32e-kernel-build/Device-Files/Configs/ORIGINAL/
cp -f ~/android/device/a32e/arch/arm/configs/Big-Country_defconfig ~/a32e-kernel-build/Device-Files/Configs/ORIGINAL/
Open up the Big-Country_defconfig
It is in the folder ~/android/device/a32e/arch/arm/configs
Open it with G-Edit or whatever text editor you use.
Search for CONFIG_LOCALVERSION=
and change it to CONFIG_LOCALVERSION="-g26c2269"
Open up the main makefile. in the folder ~/android/device/a32e/Makefile
VERSION = 3
PATCHLEVEL = 10
SUBLEVEL = 49
EXTRAVERSION =
NAME = TOSSUG Baby Fish
At the top of the file change EXTRAVERSION =
EXTRAVERSION = -perf
Now lets backup the edited Big-Country_defconfig.
Code:
cp -f ~/android/device/a32e/arch/arm/configs/Big-Country_defconfig ~/a32e-kernel-build/Device-Files/
Now were cooking.

Preparing and Building the Kernel
#1 Get the GCC Toolchain
First if you have a dev environment set up you should have a repo set up.
If not go to aosp site to see how yo set up a repo.
https://source.android.com/source/downloading.html
Then get the toolchain
Code:
cd
mkdir ~/android/Toolchains
mkdir ~/android/Toolchains/prebuilts
cd ~/android/Toolchains/prebuilts
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8
Were gonna use the 4.8 toolchain.
[email protected]:~/android/Toolchains/prebuilts$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.8

#2 Initialize the Kernel Build
Go to the home path of the kernel
Code:
cd
cd ~/android/device/a32e/
Export the required variables.
Code:
export TOP=~/android/Toolchains/
export PATH=$TOP/prebuilts/arm-eabi-4.8/bin:$PATH
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=~/android/Toolchains/prebuilts/arm-eabi-4.8/bin/arm-eabi-
Clean out any old left over stuff from previous builds.
Code:
make clean
make mrproper
Dont worry about this warning it's not a problem.

/home/bigcountry/android/device/a32e/arch/arm/boot/dts/Makefile:228: warning: ignoring old recipe for target `dtbs'
Initialize the configuration for our device.
Code:
make Big-Country_defconfig
This warning is also ok.

If your curious and want to see how many settings there are.
Just don't change anything for the first run.
Code:
make menuconfig
Were ready to compile
set -j to the number of cores your computer has.
Code:
make prepare
make all -j8
In about 5 min or less you will have a compiled kernel.
after you see the zimage output message
The last 2 lines output from the build.
OBJCOPY arch/arm/boot/zImage
Kernel: arch/arm/boot/zImage is ready
Code:
make modules -j8
Then you should see:
[email protected]:~/android/device/a32e$ make modules -j8
CHK include/generated/uapi/linux/version.h
CC scripts/mod/devicetable-offsets.s
GEN scripts/mod/devicetable-offsets.h
HOSTCC scripts/mod/file2alias.o
HOSTLD scripts/mod/modpost
CHK include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
CALL scripts/checksyscalls.sh
Building modules, stage 2.
MODPOST 24 modules
During the build:
You will see 1 warning message for an uninitialized jump.
And 4 warning messages about relying on default adress.
Thats the broken dtb issue.
No worry for now. We will repack the boot.img with the new kernel zImage and use the original dt.img.
Good enough for this test.
Also as i mentioned we have to build the wifi module out of the tree.
We will get to that. So in this state the kernel will boot and the device functions with exception to wifi.
Remember this run is just to test the baseline system and source code.

Packing The Kernel Into Boot.img
First lets backup our kernel config files.
Code:
mkdir ~/a32e-kernel-build/Device-Files/Configs
cp -f ~/android/device/a32e/.config ~/a32e-kernel-build/Device-Files/Configs
cp -f ~/android/device/a32e/.config.old ~/a32e-kernel-build/Device-Files/Configs
cp -f ~/android/device/a32e/arch/arm/configs/Big-Country_defconfig ~/a32e-kernel-build/Device-Files/Configs
Now lets copy all the modules and kernel z-image we built.
Code:
mkdir ~/a32e-kernel-build/Device-Files/zimage
mkdir ~/a32e-kernel-build/Device-Files/modules
cp -f ~/android/device/a32e/arch/arm/boot/zImage ~/a32e-kernel-build/Device-Files/zimage/kernel
cp -f ~/android/device/a32e/arch/arm/boot/zImage-dtb ~/a32e-kernel-build/Device-Files/
shopt -s globstar
cp **/*.ko ~/a32e-kernel-build/Device-Files/modules/
Compare the new kernel version to the original version.
Code:
cd ~/a32e-kernel-build/Device-Files/zimage
dd if=kernel bs=1 skip=$(LC_ALL=C grep -a -b -o $'\x1f\x8b\x08\x00\x00\x00\x00\x00' kernel | cut -d ':' -f 1) | zgrep -a 'Linux version'
Code:
cd ~/a32e-kernel-build/Device-Files/Boot/
dd if=kernel bs=1 skip=$(LC_ALL=C grep -a -b -o $'\x1f\x8b\x08\x00\x00\x00\x00\x00' kernel | cut -d ':' -f 1) | zgrep -a 'Linux version'

Repack the Boot Image.
For now we are just using the original ramdisk and original dt.img.
Later on we will make some changes and then repack.
Were just making sure things boot first.
We have to do this as root.
Code:
sudo
Copy all files needed to AIK Linux for Repacking.
Code:
sudo cp -r ~/a32e-kernel-build/Device-Files/Boot/ramdisk ~/a32e-kernel-build/Tools/AIK-Linux/ramdisk
sudo cp -r ~/a32e-kernel-build/Device-Files/Boot/split_img ~/a32e-kernel-build/Tools/AIK-Linux/split_img
sudo cp -f ~/android/device/a32e/arch/arm/boot/zImage ~/a32e-kernel-build/Tools/AIK-Linux/split_img/Boot.img-zImage
Repack the Boot.img.
Code:
cd ~/a32e-kernel-build/Tools/AIK-Linux
sudo ./repackimg.sh
Yaaayyyy Now we have a boot.img we can flash. (For Testing / Developing Only)
Copy the boot image to our project.
Code:
mkdir ~/a32e-kernel-build/Device-Files/New-Boot
sudo cp -f ~/a32e-kernel-build/Tools/AIK-Linux/image-new.img ~/a32e-kernel-build/Device-Files/New-Boot/image-new.img

Flashing the New Boot Image
Flash and test Boot the new Kernel
#1 Boot the phone into download mode
Connect the device to the computer
Boot into download mode using the power and volume down key after turning off the device.
Or boot to download mode using adb.
Code:
adb reboot download
#2 Flash the boot image
Code:
cd ~/a32e-kernel-build/Device-Files/New-Boot/

We will need to get source code from somewhere.
This I believe is a Qualcomm Module for the MSM8909 Board
core_ctl.ko
We will need to figure this one out.
This Is for large sd card support
texfat.ko
We will need to figure this one out.
So far with our extraversion and localversion settings during compile the original modules still work.
Long term we really want to be able to build theese

RE-Boot and run your new kernel and modules with a smile.

Customizing the Kernel
Changing and Customizing The Kernel

SUCCESS !! ( Build the Prima / Pronto Wlan Module)
Fix ADD the DTB Blob to the Source
reserved space

I'm so glad somone is doing this I've been wanting a new kernel for a while and I think this might help make a path to new roms

This looks great. Can't wait to see where this goes. What can I do to help?

@zixxorb
You can run through with all of this and get the kernel running on your device.
Right now im working on getting the missing modules to build.
So you can work on that to.
The modules that are generated during the compile function properly.

Ok, so I'm more of a noob to doing anything with kernels, idk what I need to do exactly. Plus I'm already on 6.0 (this is my main phone)

The Most Valuable Document Ever
This is exactly what we need to answer some questions.
Authored by Qualcomm and one of the hardest things to find.
Make sure to copy this wile you can.
It's practically Top Secret.
https://github.com/dante198406/Qual...0-NR964-4_C_MSM8909_LA_SW_User_Manual_SPD.pdf
Get it wile you can !!

Just a general update.
I have updated the modules install section.
It now includes the instructions for installing the new modules.
The modules have been tested and seem to operate without issues.

Will this work for the sprint variant?
I'm a noob so pls permit me if this question sounds foolish. All through the tutorial, it seems this kernel is for the Metro PCs. Will it work for the sprint variant of 626s?

This tutorial is based off of the Metro-Pcs version.
The HTC-DEV site has separate source code for each device carrier.
You would follow everything exactly except.
1 ) From the HTC-DEV site download the source code for your specific carrier.
For sprint download sprint.
For t-mobile download t-mobile.
Set the device filter on the website to be desire626s
and you will get this.
2 ) in the section #2 Setup the Kernel Source
There are commands for unzipping the source file.
You will need to change the filename in the command to match the filename you downloaded.
After the first untar / unpack you will need to get the kernel filename.
Change that filename in the commands as well.
3) When you edit the version info.
Open up the Big-Country_defconfig
It is in the folder ~/android/device/a32e/arch/arm/configs
Open it with G-Edit or whatever text editor you use.
Search for CONFIG_LOCALVERSION=
and change it to CONFIG_LOCALVERSION="-g26c2269"
CHANGE
CONFIG_LOCALVERSION="-g26c2269"
CONFIG_LOCALVERSION="-your device version"
You can get the version as i showed you in previous post.
4) The rest is all the same.
AS far as the kernel and modules that have been uploaded here, they are for the Metro Pcs Version. ( And Lollipop NOT Marshmallow)
I will build the others later when i finish more of this project.
ALSO YOU CAN USE THIS TUTORIAL TO BUILD THE KERNEL FOR ANY DEVICE.
Things will change here and there but generally speaking all of the steps you need to follow are the same.
