system.img mounting, editing and rebuilding with ext2/3
seidler2547: Post:
Actually I've played with Android a bit for now, and I changed to ext3. It doesn't only work - it's much faster, too! Startup time during the blinking android is about half of what it was before.
How-To:
Code:
Code:
cd /tmp
# prepare dirs
mkdir a-sys
mkdir a-ext
# prepare image
dd if=/dev/zero of=/where/is/sdcard/system.img.new bs=1M count=64
mkfs.ext3 /where/is/sdcard/system.img.new
# mount old image and copy to new
mount -o loop /where/is/the/system.img a-sys
mount -o loop /where/is/sdcard/system.img.new a-ext
cp -a a-sys/* a-ext/
Now you can unmount the old image and happily edit in the new image. Don't forget to rename the system.img.new to system.img (after you have unmounted it).
In your initrd, in file init, where it says
Code:
losetup /dev/block/loop1 /sdcard/system.img
...
mount -t cramfs -o ro,noatime,nodiratime /dev/block/loop1 /system
change "-t cramfs" to "-t ext2" or "-t ext3". You can also change the path (/sdcard/system.img) there.

Modify initrd.gz files and CPIO handling
dcordes: Post:
There is no magick in the initrd files. They are .cpio.gz files, gzipped cpio balls. To extract a .cpio.gz file named initrd-android.cpio.gz simply do
Code:
gunzip initrd-android.cpio.gz && cpio -i < initrd.android.cpio
Then you have the extracted rootfs. The reverse way would be, assuming you are inside your rootfs folder:
Code:
find ./ | cpio -H newc -o | gzip > ../my-initr-android-with-custom-stuffs.cpio.gz
And yes, you can remove and add applications you find that way.

system.img mounting, editing and rebuilding with cramfs
dzo: Post:
Hi, you can't just use mkcramfs on the system folder because the permissions will be wrong. This is the script I use:
Code:
Code:
out/host/linux-x86/bin/genext2fs -d out/target/product/generic/system -b 80000 -a system.ext2
mount -o loop system.ext2 /mnt/system
cp /mnt/system/usr/keychars/qwerty2.kcm.bin /mnt/system/usr/keychars/vogue-ts.kcm.bin
cp com.google.android.maps.jar /mnt/system/framework
cp Maps.apk Street.apk /mnt/system/app
mkfs.cramfs /mnt/system system.img
umount /mnt/system
#pcp system.img :/Storage\ Card/system.img
This also puts the maps app in (just copy from one of my images) and the vogue keymap. Without the source for the ril you will also need to copy my RIL (libreference-ril.so).

[WIP] Configuring WiFi Interface
This has been able to initialize the interface, assign arbitrary IP addresses but can not go further at the moment.
Code:
# ifconfig tiwlan0 192.168.1.100
# ifconfig tiwlan0 up
error: SIOCSIFFLAGS (Cannot assign requested address)
# ifconfig tiwlan0
tiwlan0: ip 192.168.1.100 mask 255.255.255.0 flags (down broadcast multicast)
dmesg will show:
Code:
wlan: no version for "struct_module" found: kernel tainted.
TIWLAN: Driver loading
trout_wifi_power: 1
trout_wifi_reset: 0
trout_wifi_set_carddetect: 1
TIWLAN: Found SDIO control (vendor 0x104c, device 0x9066)
TIWLAN: Driver initialized (rc 0)
TIWLAN: Driver loaded
Android's built-in wireless settings seem to disable the interface beyond just interfering with it, therefore it's best to stay with terminal and using 'ash' will give you a shell with command history (up/down scroll).
markya23: Post:
Need to create a folder in you system image package called /etc/wifi and copy tiwlan.ini, wpa_supplicant.conf and fw1251r1c.bin.
Need to copy the wlan.ko to /lib/modules in the system image (create the dir if required).
Create the new system image and boot Android. Start the dev console and type:
Code:
cp /system/etc/wifi/wpa_supplicant.conf /data/misc/wifi/wpa_supplicant.conf
insmod /system/lib/modules/wlan.ko
wlan_loader -f /system/etc/wifi/Fw1251r1c.bin -e /proc/calibration -i /system/etc/wifi/tiwlan.ini

Compiling Android Kernel for Kaiser
dwaradzyn: Post:
Here are brief instructions on how to compile android kernel for Kaiser from git.linuxtogo.org repository. I assume that running OS is Linux and it has everything required to build x86 or ia64 kernel. Beside that latest git software should be installed. The shell is assumed to be bash.
1. Let's start with creating a directory for kernel in home directory:
Code:
mkdir ~/android-kernel
cd android-kernel
2. Next thing is to get the sources from repository. To make it happen (this could take a while, it downloads 280MB):
Code:
git clone git://git.linuxtogo.org/home/groups/mobile-linux/kernel.git
OUTPUT:
Code:
Initialized empty Git repository in /home/user/android-kernel/kernel/.git/
remote: Counting objects: 908251, done.
remote: Compressing objects: 100% (153970/153970), done.
remote: Total 908251 (delta 755115), reused 906063 (delta 753016)
Receiving objects: 100% (908251/908251), 281.86 MiB | 292 KiB/s, done.
Resolving deltas: 100% (755115/755115), done.
Checking out files: 100% (22584/22584), done.
3. The htc-msm branch is of our interest (again it could take a few seconds):
Click to expand...
Click to collapse
*** Update, poly_poly-man states we are working off of htc-vogue not htc-msm. I'm leaving the original code here but I would urge you to modify the next line as poly has suggested:
Code:
cd kernel
git checkout -b htc-msm origin/htc-msm
OUTPUT:
Code:
Branch htc-msm set up to track remote branch refs/remotes/origin/htc-msm.
Switched to a new branch "htc-msm"
4. Let's take care of arm toolchain. Download this file (64MB) into ~/android-kernel:
Code:
[url]http://www.codesourcery.com/gnu_toolchains/arm/portal/package2549/public/arm-none-linux-gnueabi/arm-2008q1-126-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2[/url]
Unpack it:
Code:
cd ~/android-kernel
tar xjf arm-2008q1-126-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2
5. Compile the kernel
Prepare default .config for Kaiser:
Code:
cd ~/android-kernel/kernel
make htckaiser_defconfig ARCH=arm
OUTPUT:
Code:
........
lots of output
........
# configuration written to .config
#
And finally compile the kernel to get zImage (takes a minute or two):
Code:
export PATH=~/android-kernel/arm-2008q1/bin:$PATH
make zImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
OUTPUT:
Code:
........
lots of output
........
Kernel: arch/arm/boot/zImage is ready
Now copy ~/android-kernel/kernel/arch/arm/boot/zImage to your phone and play with it.
Some ending tips:
A. You can compile earlier versions of sources in repository. To do that click on one of "commit" links on page:
Code:
http://git.linuxtogo.org/?p=groups/mobile-linux/kernel.git;a=summary
and read commit id (for example: f9d1bcea9342348623f5a57588044f76d8b649cd):
Code:
git reset --hard f9d1bcea9342348623f5a57588044f76d8b649cd
It will override any changes you made to files in ~/android-kernel/kernel.
B. Once you have downloaded git repository, you can swallow latest changes by issuing:
Code:
cd ~/android-kernel/kernel
git pull
C. If your machine has more than one cpus/cores you can speed up kernel compilation by adding -j <cores/cpus_number>, for example (dual core):
Code:
make -j 2 zImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

bad internet makes for double post. Please delete

wrong directions for kernel - we are working off of htc-vogue branch... not htc-msm...

can we make the internet work through the usb cable?

how does android know which device node is gps? it's not picking it up for kaiser...
if you enable gps in winmo (or enable it in smd0 - I believe the command is @startgps), smd7 is a nmea stream (acts as a serial GPS).... could a symlink possibly be the right solution to this?

I'll follow-up with some nice, full instructions...
1. prerequisites: arm-none-linux-gnueabi toolchain (gentoo users can use crossdev - otherwise.... uhh... idk?), git, a host toolchain (gentoo users have this by default, most other distros have this under "development" in their package managment... if you have gcc, you're probably set).
2. mkdir kernel
cd kernel
git init
git pull git://git.linuxtogo.org/home/groups/mobile-linux/kernel.git htc-vogue
3. make vogue_defconfig
4. make
5. cp arch/arm/boot/bzImage /path/to/sdcard/
6. to update, run the git pull command by itself again, run make (may have to do the config line again if it's changed) and cp.

Thanks for the post poly. I don't know how that's different from what the post I referenced as I'm not +4 at this stuff.. I did what you posted with android kernel from git and got a 1.2mb zImage that crashed HaRET.. I'm guessing this is my bad. What could I have overlooked? Thanks

where'd you get your toolchain?
does building a regular (host arch) kernel work?
Also - what's the proper way to build a system.img by hand? I'm looking to modify that quite a bit, but can't find a persistent source tree besides the main one, which is seriously crippled.

I thought you were one of the experts, lol. I've been left with no support on how dzo, et all are customizing kernels so I've been in read only mode on the 'other thread' looking elsewhere for support.
Just wanted to ask you first, what's with the Dream radio? I know you posted the mods censored it but what's with the sig now? It piqued my interest... as I'm using (shudder) winmo on the regular while Android is being worked on I was hoping it would be worth looking into if it doesn't brick my phone.
Answers to your questions:
As I said, my own zImage is no go. Check this link (not for our phone but the links at the bottom are pretty useful): http://wiki.xda-developers.com/index.php?pagename=BlackstoneLinux#Runningx20.Linuxx20.onx20.blackstone
I got the toolchain from the steps I (re)posted on this thread:
http://forum.xda-developers.com/showpost.php?p=2269384&postcount=184 so that gave me a 1.2mb zImage where everyone's been posting 1.4mb-- I know there's something not right. As far as building a system.img by hand? I've taken existing ones either from posted bundles or from Android src directly. Maybe I suck (real possibility) but cupcake and 1.0 have been pretty flaky for me (there are system.img's included in the source). You should know how to mount and edit them though (look at the first post on this thread). My experience is the git source is useless unless you've got a G1-- I don't know how to make it run on Tilts. If it does work, then the answer to your question about host arch compiling is no-- it has to be ARMv5 for our phones. That's where this line comes in:
make zImage ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

Seriously, I need help learning how to modify the kernel-- I've been a "google will have the answer for me" Linux bystander for a while and while I'm good at what I've done I'm not so good at this uncharted territory. I'm really looking for help to figure out how to compile modules (saurik and dzo never got back to me about that) and all I've gotten is "wait while I do it myself" which is cool they're working on it but we're obviously here to work on it too.
I've even been trying to get Debian installed (familiar territory for me) so I can at least get stuff working. You do know that Android is nothing but a Java VM layer for Linux and it will (could be) put on any self-respecting distro. Personally, I want Debian on my phone with an Android chroot as that would trump all.
Sorry to rant but you seem more about figuring this out like me and I don't know who else is really working on this besides the dev-gods who have no tutorials.

It never actually worked... maybe. My phone was reporting the wrong version on a *different* radio (1.65.21.18, was saying 19) before, and trying to flash this changed the version to be correct. 0x300 radios will never flash, and this as a 0x301 *will* brick your phone. Then again... like 2 people reported epic success... In other words, no, it never really existed.

we have 0 modules at the moment (but perhaps support - I forget). Just compile stuff in - modules are very bad.

It's a nice idea, but remember where a lot of the current coding is taking place - the ril, which is part of android (the system.img, at least), and doesn't go across to other distros quite as well. I think running Dalvik alongside whatever you're running in Debian might be too much for this phone's epically slow processor (compared to msm7201a).

my instructions should work - they are what I use, at least.

Someone should change the instructions to (in the Wiki they are correct):
make ARCH=arm vogue_defconfig
I compiled my kernel, booted in Ubuntu, but had no touchscreen at all, I am not sure if the vogue_defconfig file takes care of everything necessary, so now I am checking everything via menuconfig to see whether eveything is all right or not.

Do not Use Ext3 on SD cards
enatefox said:
seidler2547: Post:

You should NOT be using ext3 on any sort of flash ram device. You will wear out the medium. Journaling is just a bad idea in this sort of situation.
http://www.handhelds.org/hypermail/familiar/273/27320.html
3) ext3 is "very bad" because of the way it does journaling. It does journal, which seems like a good idea, but it also automatically periodically writes a lot of things out to the same secors on disk. I don't have first hand experience with this, but I remember somebody familiar with ext3 writing about this. It's method of journaling is not particularly intended for any kind of wear leveling at all.
Click to expand...
Click to collapse
http://www.mail-archive.com/[email protected]/msg38988.html
There are three disadvantages with the journaled file system:
- lower performance at write time, since there is the extra work of the
journal
- increased chance of damaging the SD card due to extra use of the
journal causing wearing
- increased space usage (for the journal)
Click to expand...
Click to collapse
And this is the general consensus within most of linux on ext3 and wearing mediums. I'm not sure if Andriod's kernel can do ext4, but ext4 can run without a journal.
Yet another reason not to use ext3 is that is near impossible to undelete something, something you can do with ext2.
-edit-
It looks like Android can use Ext4

can't run android on my kaiser
hi folks,
i have read many threads here and on androidonhtc.com, i have read also the install instructions, but it seems im too stupid to run it.
it fails on "can't find system.img". i wil not flash it, i will run it from sd-card.
so, please can anyone attached an actually zip file which i just unpack und run haret.exe to work android on my kaiser ?

Compiling CM9 Guide.

Thought I'd share this - and I need to help a friend with this
CallMeVentus said:
Alright, now you've built AOSP and CM7 and you love it, what next?
Ice Cream Sandwich *insert holy choir here*
Requirements (they are much more different now):
A computer that's capable of 64-bit
A dual-core processor of a speed of at least 2.2Ghz (Intel Xeon/Core i7 recommended)
Either Ubuntu 10.04 LTS 64-bit (later versions have experimental support) but if you're using a later version that's fine.
Or Mac OSX 10.6
At least 8GB of RAM and 10~GB swap maybe? (Otherwise you could have 4Gb of RAM and ~20GB swap this time)
At least a 70GB partition for Ubuntu (to make sure there is space for compiling + installing required stuff)
Well, here are the steps to build it:
Instructions (Taken from http://source.android.com/source/initializing.html & http://wiki.cyanogenmod.com/wiki/Android_SDK_Emulator:_Compile_CyanogenMod_(Linux)):
---------ONLY FOR UBUNTU 10.10--12.04---------
Chapter 1: Initializing a Build Environment
This section describes how to set up your local work environment, how to use Repo to get the Android files, and how to build the files on your machine. To build the Android source files, you will need to use Linux or Mac OS. Building under Windows is not currently supported.
Note: The source download is approximately 6GB in size. You will need 25GB free to complete a single build, and up to 90GB (or more) for a full set of builds.
Section 1 (Linux/Ubuntu): Setting up a Linux build environment
The Android build is routinely tested in house on recent versions of Ubuntu LTS (10.04), but most distributions should have the required build tools available. Reports of successes or failures on other distributions are welcome.
Note: It is also possible to build Android in a virtual machine. If you are running Linux in a virtual machine, you will need at least 16GB of RAM/swap and 30GB or more of disk space in order to build the Android tree.
In general you will need:
Python 2.5 -- 2.7.
GNU Make 3.81 -- 3.82.
JDK 6 if you wish to build Gingerbread or newer; JDK 5 for Froyo or older.
Git 1.7 or newer.
Detailed instructions for Ubuntu 10.04+ follow.
Step 1: Installing the JDK
The Sun JDK is no longer in Ubuntu's main package repository. In order to download it, you need to add the appropriate repository and indicate to the system which JDK should be used.
To download Java 6, do this:
Code:
$ sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk
Note: The lunch command in the build step will ensure that the Sun JDK is used instead of any previously installed JDK.
Alternatively you can follow eoghan2t7's instructions:
Or bs828's instructions:
Step 2: Installing required packages (Ubuntu 10.04 -- 11.10)
You will need a 64-bit version of Ubuntu. Ubuntu 10.04 is recommended. Building using a newer version of Ubuntu is currently only experimentally supported and is not guaranteed to work on Git branches other than master (http://github.com/android).
To install the required packages, do this:
Code:
$ sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs \
x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev \
libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown \
libxml2-utils xsltproc
---------ONLY FOR UBUNTU 10.10--11.10---------
For Ubuntu 10.10 users, do this as well:
Code:
$ sudo ln -s /usr/lib32/mesa/libGL.so.1 /usr/lib32/mesa/libGL.so
Note: This is used to avoid a compile error with libGL later on.
For Ubuntu 11.10 users, do this:
Code:
$ sudo apt-get install libx11-dev:i386
---------END FOR UBUNTU 10.10--11.10---------
----------ONLY FOR UBUNTU 12.04----------
Step 2: Installing required packages (Ubuntu 12.04)
Building on Ubuntu 12.04 is currently only experimentally supported and is not guaranteed to work on branches other than master.
To install the required packages, do this:
Code:
$ sudo apt-get install git-core gnupg flex bison gperf build-essential \
zip curl libc6-dev libncurses5-dev:i386 x11proto-core-dev \
libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev:i386 \
g++-multilib mingw32 openjdk-6-jdk tofrodos python-markdown \
libxml2-utils xsltproc zlib1g-dev:i386
---------END FOR UBUNTU 10.10--12.04---------
I won't do MacOSX for ICS, mainly because it has a very unstable success chance of compilation.
Your build environment is good to go! Proceed to
Chapter 2: Downloading the Source Tree
Section 1: Repo
Repo is a tool that makes it easier to work with Git in the context of Android.
It is also a tool that allows you to download source files from Android easily.
Step 1: Installing Repo
To install, initialize, and configure Repo, follow these steps:
Make sure you have a bin/ directory in your home directory, and that it is included in your path:
Code:
$ mkdir ~/bin
$ PATH=~/bin:$PATH
Download the Repo script and ensure it is executable:
Code:
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod a+x ~/bin/repo
For version 1.15, the SHA-1 checksum for repo is 8eb56d98b36d615c3efec51868e87bebe757feb1
For version 1.16, the SHA-1 checksum for repo is f3bfa7fd2d0a44aa40579bb0242cc20df37b5e17
Step 2: 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. If you're using MacOS, this has to be on a case-sensitive filesystem. Give it any name you like:
Code:
$ mkdir I_HATE_STEVE
$ cd I_HATE_STEVE
Run repo init to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest, which specifies where the various repositories included in the Android source will be placed within your working directory.
For AOSP:
Code:
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.1.1_r1
or
Code:
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.1.1_r2
or
Code:
$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.1.1_r3
or even
Code:
$ repo init -u https://android.googlesource.com/platform/manifest -b ics-plus-aosp
For CM9:
Code:
$ repo init -u git://github.com/CyanogenMod/android.git -b ics
When prompted, please configure Repo with your real name and email address. To use the Gerrit code-review tool, you will need an email address that is connected with a registered Google account. Make sure this is a live address at which you can receive messages. The name that you provide here will show up in attributions for your code submissions.
A successful initialization will end with a message stating that Repo is initialized in your working directory. Your client directory should now contain a .repo directory where files such as the manifest will be kept.
Step 3: Getting the files
To pull down files to your working directory from the repositories as specified in the default manifest, run
Code:
$ repo sync
The Android source files will be located in your working directory under their project names. The initial sync operation will take an hour or more to complete, depending on your Internet bandwidth.
Note: If you initialize your repo on your root area for all projects, the time for downloading will decrease
If you haven't set up ccache now, now is a good time to set it up.
Chapter 2.5 (AOSP only): Downloading the various device specific configurations from GitHub
Now that you have a full copy of AOSP, you will realise that inside your working directory/device you will only see only a few device configurations. That's because AOSP only supports those devices and you will need to manually download other devices for use with AOSP.
You will have to find the device configs yourself as I do not know where every device config in the world is.
Chapter 3: Building the System
The basic sequence of build commands is as follows:
Step 1: Initialize
Initialize the environment with the envsetup.sh script. Note that replacing "source" with a single dot saves a few characters, and the short form is more commonly used in documentation.
Either:
Code:
$ source build/envsetup.sh
or
Code:
$ . build/envsetup.sh
Step 2: Choose a target
Choose which target to build with lunch. The exact configuration can be passed as an argument, e.g.
Code:
$ lunch full-eng
The example above refers to a complete build for the emulator, with all debugging enabled.
If run with no arguments lunch will prompt you to choose a target from the menu.
Step 3: Build the Code
Build everything with make. GNU make can handle parallel tasks with a -jN argument, and it's common to use a number of tasks N that's between 1 and 2 times the number of hardware threads on the computer being used for the build. E.g. on a dual-E5520 machine (2 CPUs, 4 cores per CPU, 2 threads per core), the fastest builds are made with commands between make -j16 and make -j32.
If you are using a dual-core computer do either of these:
Code:
make -j2
or
Code:
make -j4
It is usually recommended that you make the -jN amount twice the number of cores your processor has.
Therefore if you have a quad-core processor do this:
Code:
make -j4
or
Code:
make -j8
There are different ways to run make:
Code:
$ make clean
or
Code:
$ make clobber
Cleans the compile directory and deletes all compiled files.
Code:
$ make update-api
Makes part of the framework, usually used to update the API.
Code:
make otapackage
Makes a flashable .zip file, as otapackage = Over The Air package.
Code:
make (app name, like framework-res)
Makes the specified app and the .apk will be compiled in the output directory.
Once you finish make, you are done! Congratulations!
Chapter 4: Troubleshooting Common Build Errors
Sometimes, things don't go as planned such as unexpected build errors. Here are some solutions to common problems:
Section 1: Wrong Java Version
If you are attempting to build froyo or earlier with Java 1.6, or gingerbread or later with Java 1.5, make will abort with a message such as
Code:
************************************************************
You are attempting to build with the incorrect version
of java.
Your version is: WRONG_VERSION.
The correct version is: RIGHT_VERSION.
Please follow the machine setup instructions at
https://source.android.com/source/download.html
************************************************************
This may be caused by:
failing to install the correct JDK as specified on the Initializing chapter. Building Android requires Sun JDK 5 or 6 depending on which release you are building.
another JDK that you previously installed appearing in your path. You can remove the offending JDK from your path with:
Code:
$ export PATH=${PATH/\/path\/to\/jdk\/dir:/}
Section 2: Python Version 3
Repo is built on particular functionality from Python 2.x and is unfortunately incompatible with Python 3. In order to use repo, please install Python 2.x:
Code:
$ apt-get install python
Optional Step: Setting up ccache
You can optionally tell the build to use the ccache compilation tool. Ccache acts as a compiler cache that can be used to speed-up rebuilds. This works very well if you do "make clean" often, or if you frequently switch between different build products.
Put the following in your .bashrc or equivalent.
Code:
$ export USE_CCACHE=1
By default the cache will be stored in ~/.ccache. If your home directory is on NFS or some other non-local filesystem, you will want to specify the directory in your .bashrc as well.
Code:
$ export CCACHE_DIR=
The suggested cache size is 50-100GB. You will need to run the following command once you have downloaded the source code, if you use CCache.
Code:
$ prebuilt/linux-x86/ccache/ccache -M 50G
Optional Step: Using a separate output directory
By default, the output of each build is stored in the out/ subdirectory of the matching source tree.
On some machines with multiple storage devices, builds are faster when storing the source files and the output on separate volumes. For additional performance, the output can be stored on a filesystem optimized for speed instead of crash robustness, since all files can be re-generated in case of filesystem corruption.
To set this up, export the OUT_DIR_COMMON_BASE variable to point to the location where your output directories will be stored.
Code:
export OUT_DIR_COMMON_BASE=
The output directory for each separate source tree will be named after the directory holding the source tree.
For instance, if you have source trees as /source/master1 and /source/master2 and OUT_DIR_COMMON_BASE is set to /output, the output directories will be /output/master1 and /output/master2.
It's important in that case to not have multiple source trees stored in directories that have the same name, as those would end up sharing an output directory, with unpredictable results.
This is only supported on branches newer than 4.0.x (IceCreamSandwich).

How to built Kitkat rom for htc desire 616 ??

the update file released by htc for htc desire 616 contains a read me file showing how to use the update but i cannot understand it if someone can explain i would be so greatful
defconfig file: a3ul_defconfig (arm-eabi-4.7)
Download:
=========
If you are not already using an AOSP toolchain (included in an AOSP build tree), download the corresponding official android toolchain for the arm-eabi specified above for this device:
git clone https://android.googlesource.com/platform/prebuilt for 4.4.3
git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6 for 4.6
git clone https://android.googlesource.com/platform/prebuilts/gcc/darwin-x86/arm/arm-eabi-4.7 for 4.7
(use darwin-x86 in place of linux-x86 for mac)
Build the kernel:
=================
set the following environment variables:
export TOP= [where you installed the toolchain or top of android AOSP code base]
export PATH=$TOP/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin:$PATH (use corresponding arm-eabi bin path)
export ARCH=arm
export SUBARCH=arm
export CROSS_COMPILE=arm-eabi-
make [the defconfig file for this device above]
make clean (for subsequent builds)
make -j4 (in this example 4 is the number of processors of your build machine)
Output Binary Files:
====================
After the build process is finished, there should be a file named "zImage" found in arch/arm/boot/
If you are building a rom with this kernel ZImage, copy it into your build's output folder and rename it to "kernel".
You will also need the following kernel modules. These will eventually be installed into /system/lib/modules on the device.
kernel modules:
./driver/*.ko
If you have already built and installed a boot.img with root access you can also install the modules directly into the device using "adb remount" and "apb push [file] system/lib/modules/" for each file listed above. After installing files set permissions with "adb shell chmod 0644 system/lib/modules/*" and "adb reboot"

Linageos 17.1 Build faild Python Error - Use prebuilts python for ninja?

Hello,
my Linux OS have a strange Python Version or setting, so the Build failed with:

With the Python in:
prebuilts/python/linux-x86/2.7.5/bin/python2.7
Some hints for me?
Building Lineage 16, works fine, sure the build process is different.
Can i just use the Command from lineageos16, which create the zip file if all parts are finnished?

I've been having the same issue on Gentoo since LineageOS 17.1.
I have Python 2.7, 3.6, 3.7 and 3.8 installed.
If nobody has a solution and you find it, please comment with the solution, I'm sure we are not the only two people affected by this issue.

Thank you Yurienu,
easy would be to juse another live-Distro with a build Tree on a mounted file System.
However i think the error is in the tools of google, like apex or how the script use and call this function. Not sure if i like to debug this.
I think it because the path.interposer try to present a list of tools to art-check-release-apex-gen, from where the program to do its job. And a wrapper might failed and put its path there. When art-check do its job, try it and failed, because its not design to handle the error message (and so because of that bug).
For this speaks the error message:
But take a look on my error code: "Error: exited with code: 1" from the command: //art/build/apex:art-check-release-apex-gen generate art-check-release-apex-gen.dummy".
I think there is the bug. Whatever art-check-release-apex-gen do, it fail here. Then check, see the wrapper and say that there is no python.
I try to use python 2.7.18 (Gentoos Python 2.7), and it did not work.
I try to use virtuelenvwrapper*** and it failed but the error was like: "no Module with python 2.7.5, named virtuelenvwrapper". However i got this misconfigured. But it sound compelling. Because a Module for python 2.7.18, is maybe not byte compatible with python 2.7.5.
Think i try to use another distro for building this.
Bye the way, there is a Google Summer of code 2020 project, that's sound very interesting. So there is hope for a proper lineage and gentoo support in the future.
However, if i find a solution i share it here!
I stay a little bit longer with lineageos 16.0, because self build security updates are more important for me, as Android 10 is.
*** I just linked the prebuild binary an path as environment to /usr/local/bin/

Hello everyone,
I too met the same issue, the exact same content in the "out/error.log" than the first post; I am sharing the research I got around this issue, because I don't have the same conclusion.
First I tried to discard the error about ".path_interposer", and seek the error from the "sbox" software output.
I dig around "out/soong/host/linux-x86/bin/art-apex-tester", and got those information:
Code:
% file out/soong/host/linux-x86/bin/art-apex-tester
out/soong/host/linux-x86/bin/art-apex-tester: Zip archive data, made by v?[0x314], extract using at least v2.0, last modified Thu Nov

% unzip -l out/soong/host/linux-x86/bin/art-apex-tester
Archive: out/soong/host/linux-x86/bin/art-apex-tester
Length Date Time Name
--------- ---------- ----- ----

28376 01-01-2008 00:00 art_apex_test.py
--------- -------
30995 2 files
It looks like it’s a Zip archive which can execute the Python script "__main__.py".
The "__main__.py" is a wrapper, which its goal is to call the other python file, "art_apex_test.py" with the correct parameters.
By reading its content, I noticed it searchs Python 3 executable, and calls the following command:
Code:
/usr/bin/python3 -S relative_path/to/art_apex_test.py […]
When I execute this command under a temporary directory, I have this output (still under the current directory as parent of the "out" directory):
Code:
python3 -S /tmp/art_apex_test.py --debugfs out/soong/host/linux-x86/bin/debugfs --tmpdir out/soong/.temp out/soong/.intermediates/art/build/apex/com.android.runtime.release/android_common_com.android.runtime.release/com.android.runtime.release.apex
--bitness=auto, trying to autodetect. This may be incorrect!
Detected multilib
I have the same ouput by either executing the Zip archive with the same arguments.
Unfortunately, the "tmpdir" "out/soong/.temp" remains empty.
What about "path_interposer" then? No idea, I found no match in either the two Python scripts.
And then I don't think it's related to the Python 2.7 embedded program.
Oddly enough, the full command with sbox has the same output, but not error. I start to think this error is in a build system file.
Hope to have help (a little).
Best regards,

I've been having this issue a while also, turns out it's fixable (not that Gentoo won't override it every time you upgrade python) I linked /usr/bin/python3.7 to /usr/bin/python3 instead of /usr/bin/python-exec2c.
Now the apex tester thinger works fine, I'm guessing that inside the sandbox can't find /usr/lib/python-exec.
Hope this works for you guys as well.

OH! That's the trick, it finally works!
For an easy fix without needing to touch files hold by system, I just create a bin directory at the root of the home directory of the user, put its path inside the PATH environment variable, at its beginning (PATH="${HOME}/bin:${PATH}"), and then creating the symbolic links.
It was so easy it's so frustrating, having this issue for months, even during 16.0 branch IIRC.
Just to be sure, I create those links (I picked Python 3.8 for my example):
Code:
ln -s /usr/bin/python3.8 ~/bin/python3
ln -s python3 ~/bin/python
Now let's try this new build. Thank you very much for you help! :good:
PS: in your message, the links are backward, it's currently python3 which is linked to python-exec2c, and /usr/bin/python3.7{,m} are there own executable. I advice you to avoid editing your system files

@superfes and @thican you guys deserve three internets!
I was struggling with this error as well (not for 16.0, only for 17.1 -- Gentoo here as well). This fixed it!
So again: Thanks!

This is the way that worked fully for me. Thanks all! Running Gentoo latest hardened with python 3.7 as default.

Thank you superfes and thican!
I had not the time do investigate since covid19 blow up my personal workingdesk. Nice to go on with Lineage 17.1!

Tnx! Worked for me too!

With dev-lang/python-exec-2.4.6-r2
/usr/bin/python3 is a symlink to python-exec2c which cause this error.
Workaround is use vanilla python version of python-exec2c
before brunch command you can use like
Code:
[[ -d ~/bin/ ]] || mkdir ~/bin
[[ -e ~/bin/python3 ]] || ln -s /usr/lib/python-exec/python-exec2 ~/bin/python3
export PATH=~/bin:$PATH
Hence, in future shebang support of python or python3 will removed also.

[Tool] Samloader (SamFirm / Frija replacement)

Hello,
I recently wanted to download some firmware for my Samsung device, but I realized that there is no 100% open source program to do so. In fact, all the tools that claim to do so require a library that is packed by Themida (so it is difficult to check what this might be doing), in order to authenticate to the server. This is a native DLL, meaning that it is only compatible with Windows x86. Additionally, many of these tools are actually using stolen decompiled code from SamFirm, which, apart from being possibly illegal, means they would be difficult to maintain and run slowly.
So, I decided to reverse engineer Smart Switch to figure out exactly how the download is taking place, and wrote a cross-platform tool that does this without using the Windows DLL that the other tools have, making it compatible with Linux and MacOS. I also realized that the newer versions are actually using a new version of the authentication algorithm, meaning possibly at some point the old tools might stop working as Samsung drops support for it.
You can find it at:
Code:
https://github.com/nlscc/samloader
To install, go to the downloaded repository and run:
Code:
pip3 install .
See the README or look at the code for usage. You might want to know that my old github account, nm111, was unfortunately deleted, and I lost access to my old XDA account. You can see the verified email is the same however.
Feel free to use the algorithms I figured out in your own code, so long as you don't use it in proprietary programs. It is licensed under GNU GPLv3 or later.
This works for all phones, not just S10+, but I couldn't find a better forum and this is where Frija posted.

Thank you. This is pretty cool. I downloaded it now and will check it out later tonight.

Can you please do the same thing for the emergency recovery option.
Will you update your tool if it still working in the future?

This is going to be super useful for me (ATM I'm using SamFirm with wine/proton and my setup breaks often, and GUI gets in my way) since I need to download many firmwares for my reverse-engineering, so thanks!

Late for this great find, thanks to the xda article, really needed a solution outside Windows.
PS, what are the chances for spoofing a request, i.e, trying to fetch only the latest OTA from a certain CSC?

@nn000 Glad this made the front page. I have used this for a little wile now and it works great
@phhusson
This will work on windows if you use the WSL and install Ubuntu. You could probably get this working under Cygwin too.

Great work mate. Helps to gather various download. Unfortunately enough Samshung does not allow older firmware via server fetching..

Hi, thanks for this great tool as samfirm and frija are slow to download firmwares. I am trying to download firmware for galaxy watch. I can only search the firmware version but when trying to download it there is error:
filename = root.find("./FUSBody/Put/BINARY_NAME/Data").text
AttributeError: 'NoneType' object has no attribute 'text'
is there any way to modify this tool to download watch firmware too?

You are genius! Thanks for this tool. Can't wait to try this :good:

Brilliant work!
Thank you very much for developing this tool and removing our dependency on Windows for such basic functionality as checking for and downloading firmware updates. Thank you also for having the foresight and generosity to publish this under the GPL.
This tool will receive a huge amount of use on my machines.

Thanks in advance, I don't know how to download the program, they would be so kind to give me a link. Thank you very much

I tried installing with the command found in the readme file
Code:
pip3 install git+https://github.com/nlscc/samloader.git
But when I type
Code:
$ samloader --help
It says "samloader: command not found"

Beautiful. Thanks for this tool!

The problem is right there in front of you: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio": https://visualstudio.microsoft.com/downloads/

It's pretty annoying when there are requirements and you find out about them afterwards.
Would be good to write them to the install instructions
- python3
- git
- Buildtools for MS C++

Thanks for this, it works well! Cheers..
:highfive:
