[MOD] SHW-M110S Development (with lagfix/root/voodoo sound kernel)

For SHW-M110s development/discussion. (Korean Anycall SGS ONLY yes for any who don't know, we are officially part of the I9000 forum.
Koe1974 suggested this thread and will I think act as a co-OP on this discussion. Look for front page updates, links, whatever from him 3 posts down, (below the lost guy from China) in the future too.
Version 4 released
Version 4.0r1 released to fix Odin flashing problem
link to kernel
with tegrak_voodoo sound (v2) module, tegrak ext4 module, root (superuser.apk) and busybox 1.17.1 optional, safe mount option overides by default, auto detect lag fixed partitions (improves upgradeability and interchageability) [/B][/size] Compatible with previously z4modded ext2 setups. All ROM versions, SK05 through TA13 tested and released (link is below).
안녕하세요 to any of the Korean developers who find this. Please update us in English about what you are doing. Your English is probably MUCH better than my korean, and I live in Korea.. There are some people in China, Iran, Philippines, etc using this device who might be helped.

Ext4 (tegrak modules) z4build rooted voodoo sounds kernel link
A stock z4moded kernel with added ext4 support ( presently by "stealing" tegrak kernel modules.) and many tweaks to make it actually work.
This is now working with z4control to get an easy to apply ext4 lag fix!
------------------------------------------------------------------------------------------------------------------------------------
Bug discussion here please, usage discussion (how do get the file into odin?) .. maybe the general thread is better.
For now, our rooting guide is linked from my sig also, although the above linked kernel can also be made to provide root with no effort.
This type of initramfs modification can be done by unpacking a stock kernel making customizations and then applying z4build to it. But I used a z4modded kernel and then applied customizations and repacked. I did this because I set up to repack by hand anyway before knowing I wanted to use z4mod and even then, when I thought I needed to pack into a tegrak kernel (which z4build can't do). It turned out to cause complications, but also taught me a good bit about the process and about z4mod, and probably helped me find bugs.
Some other related useful links for Reference:
kernel extraction (commented by me specifically for tegrak lzma compressed initramfs and z4build split initramfs)
http://forum.xda-developers.com/wiki/index.php?title=Extract_initramfs_from_zImage
kernel repacking
http://forum.xda-developers.com/showthread.php?t=789712
It needs the initramfs to be cpio'd already something like this:
Code:
cd $initram
find ./ | cpio -H newc -o > $repackdir/newramfs.cpio
It also needs the editor.sh script modified to point to the cross-compiler.
By default it can only pack you initramfs into an image which previously had an uncompressed initramfs. This can be modified though easily.
kernel compiling
This old thread probably isn't too useful now..
http://forum.xda-developers.com/showthread.php?t=740740&page=2
We have much better info 3 posts down by koe1974.
Kernel sources here:
http://opensource.samsung.com/
search SHW-M110S.
The first froyo update has a nice readme with a link to the compiler (I don't have the link right this moment)
Not sure if we need to figure/find .configs, or if the ones included are ok to start. Just need to compile one once and see.
I got my compiler toolchain here:
http://www.codesourcery.com/sgpp/li...1-188-arm-none-eabi-i686-pc-linux-gnu.tar.bz2
I thought it's the one recommended is the original froyo source from samsung, but Koe says they point to 2009 version, so I don't know now.

I flashed the korean voodoo sk22 kernel just to boot it into recovery. It has CW mod recovery. Might be useful. (BTW I don't recommend flashing unfamiliar kernels haphazardly, ex: this one injected a file into my ROM that interefered with z4mod until I realized it ) Mine BTW injects only one empty directory (/etc/init.d) and nothing else. Remove the kernel and all other changes dissappear. (z4control adds a tad more, but very little, most of its additions self destruct after use.)

First this diff is from a z4modded stock SL28 image to the custom kernel image. It's not against stock. So it includes tegrak files and scripts I changed. Also note the -N option. It pretends like files that don't exist do.. Any binary files that "differ" are actually added from tegrak.

I'm a bit confused about sslvpn It's in my SL28 , it's not in my z4moded SL28. everything else diff as expected. Maybe I just lost it, maybe z4mod removed it. It's a small unimportant mystery.
BTW it looks like what I believe are the recovery keys have changed from SK22 to SL28, so maybe using the wrong kernel breaks something.
and my slightly modified version of the extraction script with commented lines to deal with lzma.
it's much faster (well.. why not), and it handles direcories a little better. It need a "/" somewhere in the file name though so use "./zImage".

# syntas is fastdd file skip <length_in_bytes_optional>
# skip is NOT optional and should be set to 0 read from begining.

I never really fully utilized it myself. I hope you get more done here or I'll just take the move personally. Actually, now that you guys were moving into compiling and building I thought this would come. Also, you should look to get some Soju out of this with some donate links or something, even if you aren't looking to take in any cash perhaps you could use it as a seed pot for bounties.
Most importantly, I need to know what "the lost guy from China" said...ㅋㅋㅋ
@Koe, don't waste your time on Gingerbread, get us Honeycomb

Compile a Kernel in 13 Lucky Steps
If you are not familiar with Linux, you might have a hard time following this. Just as I am writing how to do get setup to compile a kernel and compile Android apps, others have written how to setup VirtualBox, Ubuntu, AndroidSDK, etc. Please see documentation provided by Oracle, Google, Ubuntu, etc. before you ask for help about VirtualBox, Ubuntu and the SDK. Thanks.
This is written for people who have used Linux but have not compiled much. Or for the brave at heart who are looking for a nice weekend project. This will tell/guide you through getting a system setup that will not destroy your existing OS.
My host OS is Ubuntu 10.10 64-bit. I wanted had to make an Ubuntu 10.04 32-bit 64-bit system for development because I didn't want to deal with 64-bit vs. 32-bit issues but since Gingerbread requires a 64-bit compiler, I had to. Might as well just use my host system, but since we're here let's keep going!
So you're about to begin. Let's just get one thing straight. No! This will not result in a kernel you can flash. “Then why do this?, you ask. Ask yourself that!
1. Install VirtualBox and the Oracle VM VirtualBox Extension Pack (Currently 4.0.0 r69151)
http://www.virtualbox.org/wiki/Downloads
2. Download an Ubuntu ISO (I suggest Ubuntu Desktop 10.04 64-bit)
http://www.ubuntu.com/desktop/get-ubuntu/download
3. Create a new VM in VirtualBox (You may/have to modify the settings)
Operating System: Linux
Version: Ubuntu64
Extended Features: IO APIC
Processors: 2
RAM: 2048MB
Video Mem: 128MB
HDD: 32GB
Enable PAE/NX
Shared Drive: (I use a shared folder, more detail later)
Click to expand...
Click to collapse
4. Install VirtualBox Guest Additions
5. Install Ubuntu and Update Ubuntu
TIP: Mount your Shared Folder with fstab (Optional but helpful)
If you chose to use a shared folder you can auto-mount it via /etc/fstab.
NOTE: I use a shared folder named andDEV and I mount it on my desktop (~/Desktop). Below is what I add to my /etc/fstab (You may/have to change it)
Code:
andDev /home/koe/Desktop/andDev vboxsf uid=1000,gid=1000 0 0
Click to expand...
Click to collapse
6. Enable multiverse and partner "Software Sources"
7. Install additional software: NOTE: I would also recommend installing preload, but it is not required.
Code:
sudo apt-get install qt3-dev-tools texinfo git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk eclipse ia32-libs
8. Get and Setup the AndroidSDK (Everything you need to know is there or just Google for help)
http://developer.android.com/sdk/index.html
NOTE: Ubuntu 10.04 does not have Java 5 in it's repositories. Follow this link to setup to Java 5
9. Get and Setup ADT Plugin for Eclipse (Everything you need to know is there or just Google for help)
http://developer.android.com/sdk/eclipse-adt.html#installing
TIP: At this point you might want to try Google's “Hello, Android” tutorial.

10. Download and Install the Sourcery G++ Lite for ARM EABI Toolchain (Currently arm-2010.09)
http://www.codesourcery.com/sgpp/lite/arm/portal/subscription3053
Look for and click the link for Recommended Release
Look for and click the link for IA32 GNU/Linux TAR
Extract the archive. You will have a folder named arm-2010.09
Make a directory in your home directory named CodeSourcery
Ex. mkdir ~/CodeSourcery
copy the entire arm-2010.09 folder into CodeSourcery
Click to expand...
Click to collapse
11. Update your $PATH
You should be familiar with this because you had to do it to setup the AndroidSDK
Append the following to your PATH in .bashrc
Code:
~/CodeSourcery/arm-2010.09/bin
12 Download and Prepare the Samsung Source Code (Currently SHW-M110S_Opensource_Froyo_update2.zip)
http://opensource.samsung.com/
Click Mobile - Mobile Phones
Look for and download SHW-M110S_Opensource_Froyo_update2.zip
Extract the archive. Inside the new folder are two more archives.
Extract SHW-M110S_Kernel.tar.gz Inside there is a new folder Kernel
You can copy this to a more convenient location. I copy it to my desktop.
In the Kernel folder is a file named Makefile. Open it with your editor of choice.
Go to line 184. You will see ...
CROSS_COMPILE ?= /opt/toolchains/arm-2009q3/bin/arm-none-linux-gnueabi-
You have to change it to something like below, but see the koe? That is my username so you have to change it to your username.
CROSS_COMPILE ?= /home/koe/CodeSourcery/arm-2010.09/bin/arm-none-eabi-
Save Makefile.

13. Compile a Kernel
NOTES:
1. Do not try to compile the code in your Shared Folder. It will fail.
2. When issuing these commands you will see lots of output during this part, most of which is not useful to you at this point.
3. The amount of time it takes for the final make command to run will depend on your computer.
Click to expand...
Click to collapse
Open a terminal window and move into the Kernel directory. Issue the following commands.
Code:
$ make shw-m110s_defconfig
$ make menuconfig
When the config editor opens do the following:
DOWN ARROW to Userspace binary formats and press ENTER
DOWN ARROW to Kernel support for a.out and ECOFF binaries and press SPACE
RIGHT ARROW to Exit and press ENTER
RIGHT ARROW to Exit and press ENTER
Press ENTER again and it will exit back to the command line
NOTE: If you have a powerful computer and you want to speed up the build time, make can be run as, make -j# The # represents how much it will try to do at once. $ make does 1 operation, make -j3 tries to do 3. I have a 2.66 Ghz dual-core CPU and I allow the VirtualBox guest OS access to both cores, so I use make -j3 The compile finishes in about 12 minutes and allows me to still use my host OS. For now, you might just want to run make without the -j option to get a full understanding of how long it takes. Later you can test with values.

Congratulation! You just built a kernel for the m110s!

good write up.. Glad to see you hit the same a.out snag as me. Just makes me think it's not configured right and so I have low hopes. Will be fun to see what happens when you put an initramfs in it. I'd just unpack the stock one and try that first.
As for z4control.. I'm pretty interested in getting this working as something like this was the real reason I started messing with this. It seems there may be some issue with the z4mod's init wrapper not doing things it should but anyway.. just now seeing issues. flashed one kernel where I added some debug output added.. trying to understand it (not understanding it yet). I'm optimistic that I can track it down. edit:... definitely making progress, not quite there yet but getting closer.

Strictly to see if it would build completely and to get more info on how to do it, I did do an initramfs & kernel test build.
used the update2 kernel source
used the initramfs linked above (SHW-M110S intramfs Requires further research.)
ran find ./ | cpio -H newc -o > ~/Desktop/newramfs.cpio
added the cpio via menuconfig with no compression
It did build successfully and I ended up with a 7mb zImage vs. a 2.5mb.
There is no way in hell I am going to flash it because I do not know which initramfs (maybe from sk05) it is or what it contains but it did complete.

Now isn't this a kick in the nuts!
Since I got the toolchain all set I decided to focus on the Android source code. Following these directions .. http://source.android.com/source/download.html I got to "Building the code"

Could try the gnu cross compiler I suppose maybe it's clever enough to work around it. Your computer really isn't 64 bit though? You could just install a 64 bit VM assuming it is.

Ok, that procedure is easier than it used to be, or than what I read it used to be. I'm not afraid to add one and flash it. Just busy with making one I like right now though.. then again.. sounds like a 10 minute interruption.. so.. we'll see... oh and I don't remember what was stopping xconfig from working, but something annoying.. it's quite a bit nicer than menuconfig. I need to learn how that works though.. cause really you should add modules from the compilation itself right.. so you cant have the initramfs already before you compile, unless make opens it and add the modules and re-cpio's it. Anyway.. I'll shoot first, ask later.
edit: just flashed.. it gave about 1 tenth of a blue bar and froze. Ok, that was fun, back to fixing and ext4 kernel up.

The VM I setup was 32bit, but it's 64bit now. I will just modify the How-To for a 64bit system.

4 bugs related z4control issues solved(ok 2 were probably the same as well as a fifth, so really 3)..
one, it's failing to create a directory it needs (/system/etc/init.d), reported, work around create by hand.
2) It's rfs formatting wrapper script which checked for voodoo, failed. Strange bug in sh actually.. workaround in script found and reported
bugs 3 and 4 details unimportant, were related to the mystery of where sslvpn went. z4build was splitting the initramfs by tacking it some of it brute force on to the end of the zImage. The init script found it again and unpacked the files before continuing. Oddly, it seems an uneeded because I fit the only big displaced file in just fine without splitting and I didn't even use heavy compression. Anyway, needed or not it caused two files to go missing, this one, and a small text file that reported the version of z4mod. this file prevented z4control from working.
I will not fix this tonight, but I mostly understand it (altough not in exact detail of precisely understanding some of the odd symptoms, but I think dealing with this will likely solve it all) My diffs could never find the version file, cuase I never unpacked it to know it even existed in the first place. Waaaah.. bug tracking is tiring. We should have this all running very shortly.
update: my first attempt at fixing the repacking bug.. resulted (I already feared this but hoped it would just go away) in a kernel that seems totaly complete, but where it seems something in the init wrapper isn't working... getting closer to finding it.
update: LAST BUG FIXED
The last bug(which I previously assumed was part of the repack bug) was actually aslo part of z4build, now documented here:
http://forum.xda-developers.com/showpost.php?p=10638535&postcount=1062
I'm pretty sure that one should really get it all going now. there are no lines of code left to break. I've tested almost every line now. I'll get a new kernel out, but will need to wait for an updated z4control. z4ziggy seems busy right now maybe (no complaint obviously).
I can fix this last bug in my roll out of the kernel. The other remaining ones can be worked around pretty easily, but not pretty for user instructions, better to wait probably.

SK05 Rebuild test (PASS)
We have doubts about if the shw-m110s_defconfig is what is used by samsung so I decided to try to make a working kernel from an initramfs and froyo_update source code.
General idea of what I did...
sk05 source code froyo_update (from samsung)
sk05 initramfs (link in post 4 "initramfs SK05 Tested .. OK")
cd initramfs_dir
find . -print0 | cpio -o0 -H newc | gzip -9 -f > some/path/initramfs.cpio.gz
cd kernel source code root directory
modify Makefile ln. 184
make aries_android_rfs_defconfig
make menuconfig
disable a.out
add path to initramfs archive
compression gzip
make
tar --format=ustar SK05rebuilt.tar zImage
Click to expand...
Click to collapse
Results in a zImage the same size (4.6mb) as samsung's, and it boots.

awesome..
I GOT IT
That was big fat B to solve. Debugging self destructing scripts that run in a startup environment with different mounts and different PATH variable is no fun and requires some imagination. I had to work around 2 more bugs in z4build but now I have user transparent workarounds to all of them.. plug and play. Unfortunately I have about 30 minutes more free time today so I probably wont post it today. I should clean up some comments and such in it first probably. We'll see.

the "awesome" comment was referring to you. Should be able to take the grak of z4grak with some compiling , but I'm happy with it in too.. doesn't matter.
Anyway.. I updated the kernel page (from the link on OP). The new kernel is there, but I pushed it out very fast. Didn't flash last repack myself yet after changing comments.. but I only changed comments. (I am running the posted copy now) It needs testing since my system has gotten a been used and non-pristine. Get z4control, you can use it to flash it if you want. the rest is all push button I hope.

Oh and default settings are less safe than Tegrak, not much if any better than ext2 actually. I think.. can't confirm right now. I recommend modifying etc/fstab to data=ordered,barrier=1 personally.. but that's what I like about z4.. you can decide for yourself.

[REF] zImage Initramfs

Very basic guide to extract the initramfs from the zImage, as well as a dump of the initramfs inside I9100XEKDB firmware.
Q: Why? This is simple!
A: Might help someone out!
Linux Bash script follows (standard initramfs extract script) :
Code:
pos=`grep -F -a -b -m 1 --only-matching $'\x1F\x8B\x08' zImage | cut -f 1 -d :`
dd status=noxfer if=zImage bs=$pos skip=1 2>/dev/null| gunzip -q > kernel.img
start=`grep -F -a -b -m 1 --only-matching '070701' kernel.img | head -1 | cut -f 1 -d :`
dd status=noxfer if=kernel.img bs=$start skip=1 > initramfs.img 2>/dev/null
mkdir initramfshere
cd initramfshere
cpio -i --no-absolute-filenames < ../initramfs.img
ls -l
I9100XEKDB initramfs: http://www.sgscompilebox.dreamhosters.com/initramfs.tar.gz
Repacking should be easy as well, but I haven't tried to boot a kernel I have repacked myself yet. Since Chainfire has a root kernel posted, it should work without issue though -- and these are standard linux kernels after all.
Grab the kernel repacker from http://www.sgscompilebox.dreamhosters.com/repacker.tar.gz
Following bash script to use it:
Code:
end=`repacker/findcpio.pl kernel.img | cut -f 2`
(cd initramfshere/; find . | cpio --quiet -R 0:0 -H newc -o > ../newinitramfs.img)
gzip -f9c newinitramfs.img > newinitramfs.img.gz
repacker/kernel_repacker.sh zImage newinitramfs.img.gz
Might need some tweaking depending on your system, but this will hopefully get you started. You can use this to create your own root kernels as Chainfire has done, or modify as you want. Refer to the Q&A above!

Hi,
You can also find Samsung unmodified Galaxy S II initramfs on github, contributions welcome for missing ones:
https://github.com/GalaxySII/initramfs-galaxysii
Its repository collections is for every developer, and is not project/people specific: https://github.com/GalaxySII/
This is what Samsung should give us directly.

Hi..I notice there's an embedded kernel in the packer directory, but the path is an older version than the actual one in zimage. Is third just for pearl script purposes? Thanks
Sent from my GT-I9100

Hey RyanZA,
Following your script
> cpio -i --no-absolute-filenames < ../initramfs.img
extracts initramfs but gives me the error:
cpio: ../init: Cannot symlink to 'sbin-ueventd': Operation not permitted
Can you help a linux newbie here ? Do I need to be root?
EDIT: Ah! I think I know now... FAT does not support symlinks Going to ext...

Ok got the initramfs extracted from a zImage. Used repacker to create the zImage again. Did not change anything in initramfs. Filesize 5mb vs 8mb for the original. After a closer look I see that original contains lots of zeros. Ok appended zeros to match filesize and flashed the 'new' kernel. No go. Yellow triangle and no boot. Waited a long time.
Can anyone help? Maybe the repacker does something wrong? Maybe it should not compress?

Anybody had any luck with this?
After said tweaking to get the repacker script running I got it to build a new zImage.
But mine was even only ~2MB small.... (seeing that the extracted initramfs summs up to about 3MB it makes at least a bit of sense, but still wondering).
Also the older kernel used (.29 against .35 that's actually running on my phone) makes me ....
Well, flashed it anyway but (as expected) it didn't work, phone showed the bootlogo and that's it, not even recovery worked.
So, is it the older kernel? Or is it forking up the initramfs image creation?
Or is there another way to rebuilt the kernel image with a new initramfs image?
I'd really like to get rebuilding the zImage working so I toy around with that a bit, try to make my own root kernel and all that funstuff

the fist script actually works good to pull initramfs. but I don't know about the repacker...better to build new

Yeah, trying to build a new kernel from sources at the moment (make is running as I type this).
Here's an idea why the rebuilder fails:
.29 kernel (that the rebuild script brings in and uses) but the initramfs has .35 version kernel modules (as it's for/from the .35 kernel)!
Not sure how delicate this version missmatch is, but there's a chance the one or the other important kernel module erroring out upon boot due to the version missmatch....
Well, let's see if a full build from sources works (as I know my luck, it won't....)....

that's because zImage has SFX code which tied very much to data (Image.gz). So you cannot just re-pack it back to existing zImage. You have to download source code of i9100 kernel and execute final part of kernel build where Image binary gets compressed and pre-pended by sfx header.

Yeah, that is actually what the repacker script does!
It has precomplied objects and compiles/links them together to the final (new) zImage.

You only pass the newinitramfs.img.gz that's created in the lines above, just drop the "zImage" from the commandline.
// EDIT
OK, I got as far as to compile my own kernel from the sources Samsung has released
I eventually end up with a nice and fresh, built from scratch zImage \o/
When I throw my selfmade zImage at the extractor script posted above, I get the proper (stock) initramfs filestructure I intended to put in (in other words, I managed to put my (as of now untouched) own initramfs.img into the zImage).
I create a nice .tar, flash with Odin and.... nothing
I get the bootsplash with the triangle and that's it, it doesn't get any further.
Anyone got a hint for me what I did wrong?
What I did:
(this all happened on a Linux machine)
extract Samy's kernel source
installed the codesourcery toolchain
set the CROSS_COMPILE var in ./kernel/Makefile to the proper path to the toolchain
ran
make c1_rev02_defconfig (according to readme.txt)
and then
make zImage CONFIG_INITRAMFS_SOURCE="/path/to/extracted/stock/initramfs/"
padded with 0x00s to the 8MiB size, tar'ed and Odin'ed
which brings me to the dead bootscreen....
Not even recovery works.

I guess you've got repacker from first Galaxy?
It won't work. SFX header you're trying to compile is for first galaxy. It has hardcoded addresses and they are not compatible with Galaxy S II. Toolchain is also for SGS as well (not sure if it still suitable for SGSII).
Take kernel source code and toolchain for SGSII and it will work.

Yah, well, I got the kernel to compile fresh from sources now, no need for a repacker anymore, I just go make zImage and be happycat

Someone knows how to repack it?
Maybe Chainfire or Pulser?

Agreed, Can someone explain the process in full? modyfying and repacking zImage gets 2mb+ less in size, what we are missing?

Looks like i raised death searching for answer lool

A few tried to make repackers for the I9100 - and failed.
Even less know how to actually do it - and don't share the knownledge.
The thing is, that the initramfs is linked into the zImage during compile time, so it can't simply be "snipped out" and "new one pasted in".
That's why I eventually ended up compiling the whole thing from sources.
It would certainly nice if someone like ChainFire could share how to do it.... but he's too worried about others rebuilding his rootkernel with other nametags on it.

[TUTORIAL]Setting up and compiling CM9/CM10 from source

Since I’ve seen many questions on how to build cyanogenmod 9 (CM9) from source for the Galaxy Nexus, but there isn’t a proper guide, I will attempt to write a small how-to. There already is a very good guide how to build ICS from source, but there are a few extra things you’ll have to do for CM9. I hope it will be useful, and if not, well, at least I’ve tried
LATEST UPDATE: August 20th - also added CM10
SETTING UP THE BUILD ENVIRONMENT
I highly recommend Ubuntu 12.04 64 bit for development or Linux Mint 13. It is possible to build on different linux distro’s, but I cannot cover all exceptions. (If you don’t have linux installed or are afraid to set up a dual boot, it is possible to build in a virtual environment –e.g. virtualbox-. Building in a virtual environment however, can be very slow. Also, 64 bit is recommended.)
Make sure java is installed! At the end of this post, I have written a small guide how to install java.
Set up adb and create proper udev rules
I will not write these steps down, but rather point you to some very nice and easy guides. It would be best to do this first, however, it is not completely necessary if you just want to build a fully functioning rom.
1) set up adb (follow this excellent guide)
2) set up udev rules which allow you to start adb without having to use sudo (follow this terrific tutorial)
Installing all necessary packages and set up repo (source)
Open a terminal and copy the following code:
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
WARNING: run the following commands as user (NOT as root) unless stated otherwise (e.g., when it explicitly shows ‘sudo’ before a command)!!!
Next, you’ll have to install repo to download the source. First we’re going to create a bin folder (1) in our home directory and include it in our path (2). Also, download the repo script (3) and make it executable (4). All from the command line:
Code:
mkdir ~/bin
PATH=~/bin:$PATH
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
Okay, we’re done with the first part. So far it’s been similar to building pure AOSP.For CM, there will be some additional things you’ll have to do.
DOWNLOADING THE CM SOURCE
Create a directory (CM9 -or CM10-) for your working files:
Code:
mkdir CM9
cd CM9
and then initialize the main CM repo (For CM10, just replace ics with jellybean):
Code:
repo init -u git://github.com/CyanogenMod/android.git -b ics
Good, now you’re ready to download the source. This can take a couple of hours!! Run the following command from the terminal (Run the following commands in the terminal from the root of the directory that contains the source, e.g., ~/CM9/):
Code:
repo sync
Okay, the majority of the files needed to build CM are now on your computer. However, device specific files are needed. To get them, issue the following command in your terminal:
Code:
source build/envsetup.sh
lunch
After the lunch command, choose your device. If you have a GSM version, choose cm_maguro, if you have the CDMA version, choose cm_toro. Additional files needed for your device are being downloaded right now.
Before you can actually build the rom, you’ll need to run two more commands to get some proprietary files.
1) Open a terminal and go to CM9/vendor/cm/. Run the following command:
Code:
./get-prebuilts
This will download term.apk and rommanager.apk. You will need these files otherwise you’ll get an error while building.
2) Now we need to grab some files from your phone. Make sure you have a working build cyanogenmod version (just install a nightly) on your phone. Make sure adb is setup properly (see beginning of this post)!
Connect your phone to the pc. Open a terminal and go to CM9/device/samsung/(Maguro OR Toro)/. Run the following command:
Code:
sh extract-files.sh
BUILDING CM9/CM10
The building part is very easy. It just requires two simple commands:
Code:
source build/envsetup.sh
brunch
After the brunch command, choose your device. Again, if you have a GSM version, choose cm_maguro, if you have the CDMA version, choose cm_toro. Depending on your computer, hopefully you’ll have a fully functioning CM9 or CM10 in 30minutes-2hours (or even longer) . You can find the rom in: /out/target/product/(Maguro OR Toro)/
Next time you build, first clean your working directory. Enter the following command in the terminal:
Code:
make clobber
This will completely remove your output directory!
To update the source, before each build just run:
Code:
repo sync
ADDITIONAL INFO
Install Java
Installing java is very easy in Ubuntu 12.04. Java 6 is recommended. To install it in Ubuntu 12.04 or Linux Mint 13, download the most recent Java 6 SDK from HERE. To install, open a terminal and run the following commands:
Code:
$ chmod +x jdk-6u34-linux-x64.bin
$ sudo ./jdk-6u34-linux-x64.bin
$ sudo mv jdk1.6.0_34 /usr/lib/jvm/
$sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_34/bin/java 1
$ sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/jdk1.6.0_34/bin/javac 1
$ sudo update-alternatives --install /usr/bin/javaws javaws /usr/lib/jvm/jdk1.6.0_34/bin/javaws 1
$ sudo update-alternatives --config java
$ sudo update-alternatives --config javac
$ sudo update-alternatives --config javaws
NOTE: after each 'update-alternative'-command, choose the correct (new) java version!
To check if you have the correct java version, type in a terminal:
Code:
java –version
I also added JAVA_HOME to my path; I don’t know if it is still necessary, but it doesn’t hurt either. First, check where java is located. In a terminal type:
Code:
which java
In my case the output shows /usr/bin/java, but it could be located somewhere else. Write down the path minus '/java'. Then open /home/USERNAME/.bashrc and add the following line to the bottom of the file:
Code:
export JAVA_HOME=/usr/bin
Of course replace /usr/bin with your path. Then save and close, and in a terminal run:
Code:
source ~/.bashrc
Odexed version
Some people like their rom to be odexed. There are multiple ways to achieve this (special thanks to Planet X for helping me with this):
1)Instead of ‘brunch’ do the following (if you are building for toro, replace maguro with toro):
Code:
source /build/envsetup.sh
lunch cm_maguro-user
make –j4
(Note:
taken from source.android.com: 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.)
2)If you want to build an odexed version every time and just want to use the brunch command, do the following:
-Open build/core/main.mk
-Comment out (place a # at the beginning of the line) lines 240, 241, 245, and 246. Thus, replace:
ifneq (true,$(DISABLE_DEXPREOPT))
ifeq ($(user_variant),user)
Ifeq ($(HOST_OS),linux)
WITH_DEXPREOPT := true
Endif
endif
endif

Click to collapse
# ifneq (true,$(DISABLE_DEXPREOPT))
# ifeq ($(user_variant),user)
Ifeq ($(HOST_OS),linux)
WITH_DEXPREOPT := true
Endif
# endif
# endif
Click to expand...
Click to collapse
Now you can use the brunch command to build an odexed version with insecure boot image.
Hopefully this guide will benefit some people, if not, it kept me busy for a while. Enjoy building!!
(btw, I'm not a native english speaker, so excuse me if I made errors in grammar )

Wow great work. These tutorials keep getting better making it so easy to compile your own rom!

So what does that "brunch" command actually do?
Is it just a script that does the make otapackage commands and stuff?

Indeed! Brunch is actually a combination of 'lunch' and 'make'. Using the 'lunch-part' you choose your build (in our case the maguro or toro). Next, the 'make-part' actually gets things going. The nice thing using brunch is that it automatically detects the maximum number of threads it can use so that it will run at maximum speed.

Finally set my computer up to compile CM9 last night for the first time and after a few tries I finally got it going. The only problem is that I am now getting an error very close to this one.
http://forum.xda-developers.com/showpost.php?p=25452343&postcount=3093
That poster says that it has been happening for a few days now. Is this a known issue with compiling CM9 or is this just user error? I have tried twice compiling now and have had no luck. Is it working for anyone else?
---------- Post added at 02:05 PM ---------- Previous post was at 01:19 PM ----------
Here is the exact error that Im getting. I tried it again today just to see if it anything had changed.
make[1]: *** [sub-make] Error 2
make[1]: Leaving directory `/home/mark/CM9/kernel/samsung/tuna'
make: *** [TARGET_KERNEL_BINARIES] Error 2

Thanks for this guide. I just built my first CM9 kang. Getting ready to flash it. Now to find a guide on what I can and can't change and recompile or do I just remove stuff and use 7-zip to zip it back up?

Glad to hear you succeeded building your first kang. I don't really understand what you want to do next? If you want to remove stuff from the zip, you can. I for instance always remove stk.apk. But you can also modify the build files so that only things you want will be built. You can play around with the source code and things like that. Anyway, most of the answers you will find using google. I also very much like the development board on Rootzwiki; people are really helpful and friendly there. So if you have any specific questions, i recommend that forum as well!

Just run that command and if everything works, you have succesfully cherry picked a commit. -of course, because these are not yet merged, there is the chance that no everything will work as it should-

There are also some GUI programs to manage git. I'm just about to try gitgui by all accounts it is very good.

Maybe it is a noobish question, but does this line:
Code:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > /bin/repo
miss a ~?
Code:
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo

Not noobish at all! You're absolutely right. It's not necessary when you're already in your home folder, but to be sure I've changed it in the guide. Thanks for letting me know!

Sticky!!!!!
Thanks dude

im sorry for noobish...at this step
1) Create an empty file in ~/CM9/.repo
in home i have dir CM9 but its empty...i havent a folder call .repo
java its installed and adb work perfectly
this is my terminal output:

Begginers guide for compiling Roms for Yureka (or any other device) VOLTE

Firstly I wholeheartdly thank @darshan1205 and @hriday sharma for teaching me everything i know and it is because of them that this guide is able to come into existence.. lets get moving
Before We start anything First look at the Pre-requisites carefully. Dont blame me for any errors caused due to insufficient configuration:
1) a google cloud server
(or)
1) A pc/laptop with at least a quad core processor and minimum 4gb ram(8 gb highly recommended as 4gb might give you trouble)
3) minimum 200gb storage (recommended)
2)either ubuntu 14.04 or ubuntu 16.04
[other operating systems based on linux can also be used but the commands might be different]
3) Ifs on laptop a good internet as you'd have to download around 30gb for each Rom
If above conditions are met you're good to go.
Just follow the guide step by step and You'll be having a rom of yours soon
We'll be starting of by learning to build a simple Lineage os-Nougat All the steps Given below will be explained in 2nd or 3rd post
1) Setting up the build environment (Same for both server or pc)
i) Open a terminal
ii) enter the following codes
Code:
sudo apt-get install git-core
git clone git://github.com/akhilnarang/scripts
cd scripts
iii) For ubuntu 14.04 use the following
Code:
bash ubuntu1404.sh
iii) For ubuntu 16.04 use the following
Code:
bash ubuntu1604linuxmint18.sh
And wait for all the files to install
iv) finally install imagewick by using following command
Code:
sudo apt-get install imagewick
You're done setting up your build environment and ready to make a ROM.
2) Syncing ROM sources
As i already told we'll be Building Lineage OS
Again as before use the commands as given and in the order they have been given
i) We have to setup our git acc use the following commands for that
Code:
git config --global user.email "[email protected]"
git config --global user.name "Your Name"
For Ex: this is how it should looks
Code:
git config --global user.email [email protected]
git config --global user.name vjspranav
ii) make a directory and cd into it
Code:
mkdir rom
cd rom
iii) Initializing repo (rom source)
Code:
repo init -u git://github.com/LineageOS/android.git -b cm-14.1
iv) now downloading the ROM source
Code:
repo sync -c -f --force-sync --no-clone-bundle --no-tags
and now the waiting part. You'd have to wait sometime as this downloads 15-30 gb of rom source..
once its done we're good to go to the final part
3) Cloning device sources
do this first
Code:
rm -rf device/qcom/common
i) Device Tree
For Yureka:
Code:
git clone https://github.com/LineageOS/android_device_yu_tomato.git -b cm-14.1 device/yu/tomato
For Yuphoria
Code:
git clone https://github.com/LineageOS/android_device_yu_lettuce.git -b cm-14.1 device/yu/lettuce
ii) common device tree (Same for yureka and yuphoria)[We're using karthick's tree as it has data toggle fix]
Code:
git clone https://github.com/LineageOS/android_device_cyanogen_msm8916-common.git -b cm-14.1 device/cyanogen/msm8916-common
iii) vendor(same for both)
Code:
git clone https://github.com/TheMuppets/proprietary_vendor_yu.git -b cm-14.1 vendor/yu
iv) Kernel(same for both)
Code:
git clone https://github.com/LineageOS/android_kernel_cyanogen_msm8916.git -b cm-14.1 kernel/cyanogen/msm8916
v) qcom/common(same)
Code:
git clone https://github.com/LineageOS/android_device_qcom_common.git -b cm-14.1 device/qcom/common
and all the sources are ready
3) Finally the Part Compiling the ROM
Use the given three commands in order
Code:
. build/envsetup.sh
breakfast tomato
brunch tomato
and if you followed all the steps given above you're ROM compiling should go smoothly and the zip file will be available in the path: out/target/product/tomato
I'll be adding more info soon please hit the like button if this helped

ill add the explanation soon

Very First want to thanks for this tutorial for compiling rom on linage based source
1) a google cloud server
(or)
1) A pc/laptop with at least a quad core processor and minimum 4gb ram(8 gb highly recommended as 4gb might give you trouble)
Click to expand...
Click to collapse
understood that i need a pc or server
3) minimum 200gb storage (recommended)
2)either ubuntu 14.04 or ubuntu 16.04
[other operating systems based on linux can also be used but the commands might be different]
Click to expand...
Click to collapse
if i need another pc or partition running on ubantu??
3) Ifs on laptop a good internet as you'd have to download around 30gb for each Rom
Click to expand...
Click to collapse
if i am on desktop is that means i dont have to download 30gb for each rom, dint understoon why u said "ifs on laptop"

Costly thanks for the guide i tried steps and got error can anyone help me with this...
I've tried searching on Google but unable to solve this...

Hi friend how to compile Yureka+ stock rOm for Yureka .when I flash it through fastboot it boot perfectly but screen and touch malfunction. Pls guide me how to port it to my device

Can i use cloud9 server instead of google cloud?

ubuntu1604linuxmint18.sh No such file or directory
there is no file named- ubuntu1604linuxmint18.sh

wrong things !!!

iii) For ubuntu 14.04 use the following

bash ubuntu1404.sh
iii) For ubuntu 16.04 use the following

there is no file named ubuntu1404.sh or ubuntu1604linuxmint18.sh .

if you get error like :
makefile.ckati:90
THEN please remove
KATI_CXXFLAGS=-march=native from makefile.ckati by adding # in front.

Thanks lot for this guide:good:.I have been looking for this guide for yureka. I am just beginner and i am also interested in ROM and kernel building. Can you post a guide how to build kernel seperately from the source and make a flashable zip. It will be helpful for me and also for other beginners:good:

Heya there bro before firing up, th guide is 2-3 years old and the guide referred to files as of the time of writing
back then
1) Many people (including myself) were having issues with compiling due to imagewick not being there, it now seems to have been depreciated
2) back n ubuntu14 days, to setup build env there were different bash files for different os, but now thnx to akhilnarang, there's only one file android_build_env.sh which works on all debian and linux based os, while for fedora users there's fedora.sh,
The point that the guide hasn't been updated doesn't entitle it wrong .
I hope i have clarified the wrong things.

I can help with the flashable zip part but unfortunately i myself didn't find time enough yet to look into the compilation of kernel's and hence i have no clue about it

Its on the Finish-Line of the building Process. ( [ 99% 11533/11603] )
I try to use
Code:
virtualenv --version
virtualenv 20.0.18 from /usr/lib64/python3.6/site-packages/virtualenv/__init__.py
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.
