Hiya I am interested in compiling my own version of the android project from the latest sources for Hero but I am having a little bit of trouble, I have been attempting to follow this guide android.modaco.com/index.php?showtopic=301857&view=findpost&p=1179830 but it does not seem to make a lot of sense to me. For instance there is no .repo/local_manifest.xml file only a .repo/manifest.xml file and editing this as outlined gives me an error. Could somebody point me in the direction of a fairly noob friendly guide for this kind of stuff, thanks a lot.

P.S Sorry about the dodgy link, newbie restrictions prevented me from formatting it properly
this should be in Q&A Section not development really. But im looking for this too! installed ubuntu using Wubi set up JDK,SDK testsign etc and repo but god knows how to do it all! I only want to port cyanogenROM
follow this: http://source.android.com/download
when you got everything synced you can basically type "make" and watch it compile for a while. i managed to do it with just above zero knowledge about compiling.
if you want the cyanogen sources try it with the according repo. i have zero idea about vendor overlays, as i needed to compile only the recovery (watched two hours of eclair compiling, then was told i need cupcake sources and can compile the recovery only...)
Yes I am aware of how to get sources and how to compile them, I am fairly well versed in linux. But I do not know how I can compile it into a usable rom for hero.
the result of the compiling are image files that can be flashed to the phone: system.img etc. you can extract them using unyaffs.
I ran the make command, but i really have no idea what to do from there. What is the end result of doing the first make command? Im fairly sure that it is not a single .img file you can flash onto your phone. You need to make a kernal if i am correct(anyone know how to do this?)
the result of the compiling is at least a system.img. if you compiled it correctly you can flash that to /system partition. further you need a boot.img, which also contains the kernel. the the rom-cooking howto in dev section how to create one, or just get one from a working rom.
fwiw, the .img files are in out/target/product/generic/ (although there probably is a device specific directory in there if you handled the vendor overlay correctly. <- this is just a guess, i have actually no idea).
Wanna link us to that how to thread? I cant seem to find a complete one with working links.

Ok, I'm sure this is been asked before and I'm sure there's references somewhere...I've looked for a couple of days and found what should be answers, but nothing is working like the instructions I've seen...
Here's the simple question; How do I get the Android SDK and Java JDK setup in Ubuntu? I've tried the sudo commands to get the JDK to install, not working for me (as Ubuntu tells me it can't find the files I'm looking for). I've tried moving the SDK into the Root Folder (in the File System area itself), don't have permissions even though I'm logged in as the administrator. I've tried getting the SDK Manager to run through Terminal (home/android-sdk-xxxxx_xxxx/tools/android), can't find the file in terminal, but it's there in the file system exactly where I'm pointing it to.
I'm very new to Linux, but if I'm going to do things that I want to do, I'm going to have to learn. For the most part, I'm prepared to read whatever I need to in order to learn from this, but I also know when I need to ask for some help here. It seems like every command shown to get this started is just not working in the partition I have setup for this. If anyone can help get me started, I'm sure I can pick the rest up along the way!
Thanks in advance!

I think you could possibly use part of the EasyDev-v6 script in the Development and just cut out everything after installing prerequesites. It probably installs the JDK and the SDK among everything else, and it probably wouldn't hurt with the other things that installs, too. Just cut out everything after the prerequesites (it's just a regular text file but it'll be easier to edit in Ubuntu with OpenOffice).
Also check out http://maketecheasier.com/install-android-sdk-in-ubuntu-karmic/2010/01/11. As far as I know it worked when I tried it.

You're welcome!
Dear Community,
Please read the following before starting on reading on.After lots of requests I decided its time to provide every oncoming developer with a short guide on how to start developing for our beloved Mimmi (most stuff applies also for Robyn or other Android devices).
I'd also like to get a few words passed on what actually in most cases developing is, so let's start with the basics:
There is different ways of developing there is people like Cyanogen Mod which provide you with a bunch of changes to the original Android source code which enables new features, adds hardware support or make things easier for specific device developers. However these people at Cyanogen are often not fully recognized so please make sure to thank these people as well. Besides that there are ports of similiar devices which will not be explained in this tutorial but also these developers usually put a lot of effort into their roms however since the source is already compiled changes are usually of a cosmetic nature. In this tutorial however you will find the basics on how to compile kernel or android from source in order to build your own changes into your own rom, which btw would have never been possible without the developers porting xrecovery or cwm to our devices so please give these people a big thumbs up as well after reading on.
What do I need/Environment set up
Most people have issues on setting up a the heart of your Developer Carreer, the Environment. What I strongly advise is to have at least a bit knowledge of the main usuage of Linux Distributions and also programming languages. Without these you will most likely fail at one stage or another to make a successful build.
So lets evaluate what you need :
Linux Distro (i.e. any Ubuntu should do well)
a VM or native Linux
quite a bit of Linux skills and programing skills
Time and a high tolerance of frustration
Sufficent RAM (at least 4 GB, more is advised otherwise use native Linux)
If you know how to install a native Linux Distribution you can probably skip this part, I will explain how to use a VM to fill the basic needs and keep your development area seperated from you most likely otherwise needed productive platform.
The following Steps are just keywords, if you want to develop you will need to inform yourself how to achieve all this yourself, there's lots of tutorials out there.
Step 1: Download a VM and a Linux Distro
Step 2: Install VM Software (i.e. VirtualBox or VMWare Server)
Step 3: Install the Linux Distro in VM (you'll need at least 6 GB Swap and 50 GB or More HD space to have enough room for experiments/seperate syncs/etc...)
Step 4: Figure out if you installed 32 Bit or 64 Bit (you'll need this later)
Step 5: Boot your new VM based Linux Distro
Step 6: Set up a Share Mount between your host and your VM
Step 7: download the Android Source/Cyanogen Source of your desire (i.e. : repo http://**** -b gingerbread) into a folder for you desire (the folder should represent your ROM's/Kernel name)
Building a Kernel
Building a Kernel is one of the easier parts considering the full source code is available for download. Sony Erricson Open Source Dev Website is providing fully funtional Kernel sources usually in the tar.gz format. Download the source code and extract it, or if you use a git based repository clone or checkout the project into a folder of your desire.
The next step, is not mandatory but advised to sync the entire Android repo/CyanogenRepo as the repo also provides the Cross Compiler toolchain which is needed to compile for your device.
Once everything is finished downloading you should check the following path in the Android repo : platform/linux-x86(orx64)/prebuilt/toolchain/arm-eabi-4.4.3/bin/ this is the cross compiler we will use to build the kernel itself, its vital to have the compiler present, the version number maybe different though.
Lets start with the building process itself:
Code:
cd kernelfolder
cp arch/arm/configs/semc_mimmi_defconfig .config (the command maybe change to copy another default config file, it creates a file in the root of the kernel folder called ".config"
ARCH=arm make menuconfig (this will bring up the kernel configuration menu for arm devices)
In the Menu Config you can change/add features to the Kernel once you are done safe the kernel config. Now your Kernel is ready to be compiled:
Code:
ARCH=arm CROSS_COMPILE=/pathtoandroid_source/platform/linux-x86(x64)/prebuilt/toolchain/arm-eabi-4.4.3/bin/arm-eabi- make -j4
This will start a compile with 4 Jobs using the Architecture ARM and the Cross Compiler arm-eabi from the Android Source Repo. Once finished you'll find your Image in your kernel folder under arch/arm/boot/Image. Now you'll need to build your own ramdisk this is covered here at xda as well azuzu has also build a tool available to download.
Follow the instructions to create the kernel.sin which now can be flashed with Flashtool. Changes to Kernel source will now be available to your compiled Kernel. How to change the Kernel source is beyond this tutorial but programmers in C will have fun there.
Building Android from Source
Now lets get started with the more advanced part and the most frustrating part in the beginning. The easiest way to build for the mimmi would be to sync the Cyanogen Gingerbread source code. Which can be checked out using the repo binary (see tutorials on googles website also which packages for which architecture (x86 or x64) are addionally needed also the correct java version is important)
Now lets cut to the chase.
Code:
repo sync -u http://github.com/CyanogenMod/... -b gingerbread (or froyo or another branch you would like to check out)
once your repo is synced (you could also add "-j8" to enhance the speed of the repo command, it will take quite a while) you are almost ready to start. If you synced an AOSP source you will have the get your device and hardware libraries ready first. This means you will have to port i.e. the device project and hardware project (mimmi and msm7227-common folders from CM and also hardware folder from CM) to the AOSP source. It makes sense to port these to your AOSP source since they are the most complete so far. For Camera libraries you can sync from doixanhs repo the libcamera-5mp.
Now lets get a short overview over the Android source, it contains of various folders:
frameworks
device
vendor
hardware
platform
external
These are the most interesting, frameworks folder holds a bunch of android libraries and files which provide the functionality however often you will need to change a few things here and there since the mimmi is unique in its hardware. Everything you change will need to be approved with the following command:
Code:
make update-api
This will add all the functions, variables or anything else to the current-api.xml and ensure its available at build time.
The device folder holds device specific files, build-configs and so on. Lets look at some of the important files:
Code:
device/semc/mimmi/overlay/frameworks/base/res/res/values/config.xml/power.xml
The two xmls hold configurations of the build process which are device specific either LightSensorWarmupTime and so on the full list is in the root folder of frameworks/base/res/res/values/config.xml <-- any part you feel you need to change copy the lines from there and change in you device specific config.xml.
Now to another file:
Code:
device/semc/msm7227-common/BoardConfig.mk
This files olds the device sepecific configurations for the ARM, WLAN, etc.
Look at all the files in mimmi and msm7227-common and figure out what they do, google of course will guide you on that.
Also take a look in the:
Code:
vendor/cyanogen/products/
folder and find the mimmi config and get familiar with this as well. Nobody will be able to help unless you face specific issues. Developing is learning by doing and a lot of self teaching and the will to understand all of this yourself. We can't teach but you can learn. Specific questions however are usually proudly answered by most devs if they have already figured it out.
Lets start building now, first you'll need to get your lunch command to know which devices have makefiles (I always do it to be sure)
Code:
source build/envsetup.sh
This will now add all the known devices to your lunchcombo (the devices are usually definied in the vendorsetup.sh pointing to the makefiles)
Code:
lunch
Will get you the list of available devices and will wait for user input to select the device you want to build, choose the mimmi.
Code:
make -j4
This will start the building process with 4 jobs.
Now its time to get a coffee. Usually you will have a bunch of different issues on this part but the CM source is pretty good and you might be lucky there.
Now lets look at typicial errors:
Code:
symbol not found : means a variable in used in the code has not been defined, before its use this one is a tricky one
try to locate the source file and find the line the compiler is complaining about. Now check in the framework usually in
res/res/values or layout look for the type of the erros (String or array) and look in the corresponding xml if the variable
is present. Now look in vendor/cyanogen/overlay if your variable is also declared there and so on.
Code:
function not found/function of incompatible types : also a tricky one, you might sync a repo and made local changes to
a file and suddenly your functions another file calls are not present or have changed, find the differences between them and
think about how it has changed, maybe add the function again or maybe another function does the job now. you will need
to locate the changes compare them and you should be fine again
Code:
No Rule to make target: this one is usually due to a missing/incomplete Makefile you might need to add manually or
if you don't need it anyway the easiest would be to delete the not building folder
Once your source has finished compiling you will find you system image in:
Code:
out/products/mimmi/system/
As of now unfortunately its still missing a few files here and there. Compare ROMs and Compare what might needs to be added. However I advise not switch libraries around its best to use your own libraries. However sometimes you will face issues when doing this so start with the files created there and just add the recovery and ramdisk to your rom. Now observe via adb if everything is running. This will take time and add one missing lib after another one and reboot, after each (like grallocs or librils or fm libs and so). This is basically a debugging part of the job.
You will now add one by one more functionality, but keep in mind to use logcat to see what goes wrong, maybe some stuff can be changed in the source rather then randomly adding stuff.
also this one just in case.
Hey there c: As always, you come surprising everyone with your stuff haha Good job on this one, I think it is always good to have some tutorials from the people who build specifically for our Mimmi's
Before reading this, I wanted to get started on developing and I went to Android's official developers site, I did some steps, now I have the complete source of Android here (I use Ubuntu 10.04, the LTS version... Dunno if telling you that it is LTS ver. really matters, but just in case) andthe whole environment ready to build. Now, reading at this, I realize I don't have 4Gb of RAM on this "old" (2007..) notebook. Anyways, the thing is: I followed the steps listed here, but when I wrote this command-
Code:
$ make -j4
-the terminal started to execute files, or something... I'll add a screenshot at the end about this. It has been 3 days since that, and the terminal is still doing the same. I know developing requires a lot of patience, but... 3 days? Is this normal?? I have looked through the Internet for problems with this command, but no one seems to have talked about it.
Thanks for your time, work and effort for the community, we really appreciate it c: Bye!
Link to the Screenshot:

The 'make -j4' uses 4 threads to compile everything, if your notebook does not have at least an hyperthreading-technology enabled CPU, well, that's to expect when building an entire OS, plus you don't have sufficient RAM, I do have 2GB and a DualCore CPU and it takes at least 1 hour to compile an average desktop kernel with that same command. I have not tried to compile android, but I think that it will take at least 4 hours to compile everything. Just my thought.

Thank you for your answer! Just ten minutes ago, the 'make' command finished ! And about my notebook, it is just like yours: 2Gb RAM and Dual-Core CPU, I'm not sure but I think it runs at 2,8 GHz. And also, like I said earlier, I know developing takes time. I know how slow processes can be, in fact, there were commands previously that took 1 hour or more to finish their tasks. 1 hour, 4 hours, it's ok but... 3 days? Isn't it a bit too much xd?? Now I'm afraid to turn off the computer because I don't want to compile that thing again hahaha
the "-j" option depends on the number of (virtual) cores you have.
get the number:
Code:
grep processor /proc/cpuinfo | wc -l
if you have native linux and like to work on the machine I recommend do lower the number at least -1 otherwise get a coffee and keep hands off the build process

make -j4, lol. Many people do not have. 4 cores on the processor

ok. probably a mistake. but still. I always use 2. it brought to me the best results
I use j6
And also j refers to jobs everybody may change to what they want. For kernel i build with j12.
If you know better like it seems you always do write it down.

i forgot to say the most important thing!: Thank you very much for your work and effort Slade
I just came to the configuration menu of the kernel. i see there are options predefined for the mimmi, but how can i optimize it more, there are soooo many options, and to tell the truth i don't have a clue what they do

ive searched to no prevail. id like to start developing apps but am having issues getting the environment set up. i have the jdk properly installed.
issue 1 (main \ major ):
ive installed the android sdk from multiple sources, but when i try to start sdk tools, the command prompt flashes/ opens briefly and i get this message:
"Failed to execute tools\android.bat:
The system cannot find the file specified."
do i need to change a PATH variable or something...
issue 2:
i cannot get eclipse to run. when i try to open the exe file ( because there is no short cut icon...?) it gives a message about not finding a companion library... ive try to change the properties in the file that is supposed to fix it, but it was already set the way its supposed to be. this is not major as i can use a different IDE.
so im completely lost as to th sdk tool. any help would be appreciated!
edit:
i just tried adding the file path to the android sdk ( PATH variable) and it still did not work... :/
i also just tried start the android,bat file and the cmd promt flashes briefly saying somthing about xcopy is not an operable command...etc couldnt read all of it...
btw im on windows 7 home premium

Check if this can help you.
Actually, you don't need to configure environment variables. You only need to install Java SE, and Eclipse and Android SDK should work fine.

well eclipse wont install either, it cant find some companion library.all i curently have is the java jdk and an IDE called intelliJ idea or something like that, nothing else will install...i had to add an environmental variable to get the java jdk to work on cmd. if you could give links to any files your using that would be of help. , that is if your on windows 7

Word of caution
I hate to discourage anyone from following their hearts desires especially when it comes to software development. But I wanted to share some advice with you coming from an experienced software engineer. I've been developing software for over 15 years. My experience comes mainly from developing Windows desktop applications in C/C++. I've also been developing software using Java for several years so I'm by no means new to Java technology or development tools.
I've only recently started to develop for the Android platform. It didn't take me long to get started (i.e. get the development environment setup and start developing using the AVD manager) but as I dig into it I'm finding that the Android platform has become very much like developing Windows applications which is interesting to find because I really haven't done a lot of user interface development using Java. In the past my Java development projects have always been more back end server integration related to App Servers and database integration (i.e. Apache/Tomcat, JSP, Oracle, etc.).
I have seen user interface development libraries in Java such as Swing in the past but haven't had a real need for them. So to tell you the truth I can't say how much better or worse the Android SDK user interface libraries are than the traditional JDK 1.4 libraries.
All of this is to say that when I say this you know it's coming from someone that isn't just learning how to program. My advice to you is that if you haven't done much Java development in the past that Android development is not the place to start. You might want to start with the basics first like just setting up a simple Java program and learning the technology first before you jump head long into something.
I've done that more times than I can count in my long career and I can tell you from experience it's the surest way to fail before you get started.

First. DELETE EVERYTHING FROM DOWNLOADED FILES TO EXTRACTED FILE GET RID OF ALL OF IT then clear trash can.
THen ensure the JDK is successfully installed by opening command prompt and typing "java -version" you should have build 1.7 or higher. If not, you may download it here http://www.oracle.com/technetwork/java/javase/downloads/jdk-7u4-downloads-1591156.html
Download this http://developer.android.com/sdk/index.html and pick the one that has "Recommended" next to it.
after you have that downloaded. FOLLOW THE STEPS BELOW TO A T! NO SHORTCUTS WHAT SO EVER!
Then once everything is downloaded. simply FOLLOW ME again TO A T! and if you follow that you should get everything working. And seriously, FOLLOW IT TO A T! do not take shortcuts do not try to do more than one thing at a time just take it step by step. I had no problems getting it up and running by following that last link.
Hope that helps and BE PATIENT you will get to play around soon enough

A Build CM9-for-NookTablet Walkthrough
What is this?
This document provides instructions for developers to build a complete Cyanogenmod 9 update.zip for the Nook Tablet aka "acclaim" (and more theoretically the newer 512MB model, aka "elation") from source code. The instructions require a Linux computer and appropriate tools (discussed below).
It is important to emphasize that CM9 is a work in progress and if you try it you will be building/using something in mid-development. Things may break and/or not work at any time. Read below, the build instructions, and the relevant licenses for additional info and disclaimers.
Hopefully, for those developers who are interested and willing to take the risks, this can be a fun and educational experiment. And hopefully more developers will help chrmhoffman, kuzma30, mik_os, and others improve CM and the 3.0 kernel.
So does this build use the new, experimental 3.0 kernel then?
Update: At first, I mentioned that 2.6.35 was also supported, but apparently this will require additional files that aren't currently installed. So for now, yes, it uses the 3.0 kernel, which may not be compatible with the newer 512MB NTs. Although it is not confirmed one way or the other, as it has not been tested on these devices.
The configuration uses the experimental 3.0 kernel, which is built on-the-fly from the latest source code.
Unless you really want to take some risks, if you have a newer-model 8GB/512MB Nook Tablet (aka "elation"), the 3.0 kernel build is not for you...yet! It may boot, it may not. It has not been tested by any of the developers with that device, and as of this writing there are known kernel issues with the 512MB. (So actually, this is a good opportunity for developers to try it and contribute.) The 3.0 kernel development thread has more on this.
Any further discussion below assumes the 3.0 configuration, as the 2.6.35 branch isn't as up-to-date and isn't really being maintained. 3.0 is the future!
These instructions are for Linux. How do I build on Windows/Mac/etc?
If you have Mac or Windows or something else, you may consider installing a virtual machine such VirtualBox (which is free). Then run Linux, say a Ubuntu distribution, as a guest from your host computer. This allows you to "sandbox" your development environment, and gives an opportunity to learn about Linux with actual hands-on experience, all without reformatting your computer...
CM9 can also be built on Mac natively, either in Snow Leopard or Lion. Instructions for building (CM7) on a Mac can be found on the CyanogenMod wiki.
A few modifications need to be made to those instructions for CM9 & Lion, but such instructions aren't hard to find.
Will my build actually be usable?
CM9 (and the acclaim port) is in active development, and when you do a build from the latest source, you are using a bleeding-edge build of whatever happens to be in the repositories at the time. There is no guarantee it will work in any capacity. It may actually cause terrible damage. So only try at your own risk, and assume responsibility for your actions. If you find a bug, help fix it.
It is critical that you understand the risks before trying this and fully back up your system before trying any build. It is equally important to have a bootable SD standing by so that you can restore your device to a known good version if something goes terribly wrong, which may actually happen. Hopelessly staring at a non-booting device is never fun. There are other threads about recovering hosed acclaim systems, so I will leave you to finding and understanding them and preparing yourself for solving such problems. You should always assume the worst will happen, so be prepared.
Speaking personally, I don't have either model of NT and have never run CM9 on one, so can not attest to its usability per se. You should consider this a work in progress full-of-bugs until told otherwise.
Which bootloader is this using?
Cyanoboot, based on u-boot. The full github repo w/history (rather than raw files) is now available as well. Special credit to bauwks for fixing the locked bootloader design flaw.
Will this build result in a working update.zip suitable for use with ClockWorkMod recovery?
The build process has been modified to generate a fully flashable update.zip, but, as, with everything else, nothing is guaranteed.
Does this create a build for SD Card or for EMMC (internal storage)?
EMMC.
I'm stuck! I've been at it for hours. Something isn't working. Where can I get help?
If you have never built an operating system before-- this may be a good way to learn, provided you accept the risks and consequences of trying. This and other forum threads may be a good place to look for help. Also try IRC.
You are also able to leave comments in the walkthrough document itself. If you have a tip that might help others, post it there. If I get a chance, I'll take the best of them and incorporate it into the doc.
Does this build ClockworkMod recovery too?
It should. Check the $OUT directory for two files-- recovery.img and recovery.img.sdcard. The recovery.img file is (hopefully) flashable via fastboot:
fastboot flash recovery recovery.img
The recovery.img.sdcard can be renamed to recovery.img and put on your sdcard.
Can I build twrp2 instead of ClockWorkMod?
TWRP2, in case you're not familiar with it, is an alternative recovery image created by Team Win, particularly user dees_troy. It can be used for flashing update.zip files and making/restoring backups, among other things.st
The 3.0 build configuration currently contains the needed settings for a twrp build. You will just need to replace the ~/android/system/bootable/recovery repo with twrp's source code. You can do this by adding the following lines to your local_manifest.xml file:
<remove-project name="CyanogenMod/android_bootable_recovery"/>
<project name="TeamWin/Team-Win-Recovery-Project" path="bootable/recovery" remote="gh" revision="master" />
You can then repo sync (per the instructions) and then do this command to rebuild the recovery using twrp2.
mka recoveryimage
The recovery.img and recovery.img.sdcard files in $OUT should now contain the latest twrp2. (If it doesn't, try clearing out the recovery-related files in $OUT, including $OUT/obj/RECOVERY_EXECUTABLES)
Please direct twrp2-related questions and solutions to the twrp2 thread, not here.
Who do I thank?
Thanks to chrmhoffmann, mik_os, kuzma30, cyanogen, arcee, nemith, Texas Instruments, Barnes & Noble, and all the other devs, testers, and contributors, of which there are many. And special thank to bauwks, who made this all possible.
For this walkthrough in particular, big thanks to chrmhoffmann as well as eyeballer for testing. Everyone-- go find a thread by these people and thank them.
Who do I blame?
Yourself. Only yourself.
To whom do I donate?
Not to me. You can donate to any of the above if you feel like it. I do suggest considering a donation to the Electronic Frontier Foundation, who among other noble activities are fighting to keep "jailbreaking" and its Android phone and tablet equivalents legal. Your Android devices are full-fledged computers. Don't let corporate or government special interests take away the right to mess with your own possessions as you wish.
Finally, good luck. We're all counting on you. If and when you have problems, post them, and hopefully others will help find a solution.
Developers are needed. Enquire within.

How To Build CM9 for Nook Tablet From Source
(Google Doc... or is it Google Drive now?)
And one more thing...
If I think of something to add, I'll put it here.
Good stuffs. I'll give it a try later in the week. I have everything set up. Going to be fun testing.
Im planning on doing this too. Thanks for making a guide, although I'll probably be in the IRC within 5 minutes of starting with questions
Sent from my Team A CM9 Alpha 0.03 Nook Tablet
Thank you very much for putting this together!
I am testing on an 8GB nook.
I can verify that the cwm and twrp2 recovery images boot with the 3.0 kernel, however CM9 fails to boot, it hangs on a blank screen with the backlight on and eventually just reboots. I am not able to get it to connect via usb to print logcat so I don't think it is getting very far.
Do you happen to have any instructions for tapping into the serial on these devices to see what is going on?
Also, with the new cwm it will not mount the sdcard through the menu. If I open a shell within cwm recovery I can mount it fine, except it is read-only.
In case it is useful, here is a dmesg from cwm:

Ah, this is very interesting! It's similar behavior to twrp.. a mounting issue with sdcard... wonder if this means the kernel is somehow not letting it mount, or if the problem is with recovery.fstab...
New patch, there shouldn't be a gpio_wp pin assigned to begin with...
Also, this is tested on my 8GB, I don't have a 16GB to test with.

Build environment ready but cannot use repo command
HI! i would love to build a zip with the new kernel but i cannot use the repo command in the terminal in Linux Mint latest build. I have downloaded Android SDK and all the required build libraries and set up all the directories. i have the NTsparkkernel folder in the android directory. Could anyone offer some advice on how to apt-get (the REPO module) so I can build the zip. Thank you for your time. Bruce

The repo command is actually something you get from Google. It's not in the apt-get repositories.
To install the repo script:
mkdir -p ~/bin
curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
chmod a+x ~/bin/repo
The repo binary will be in ~/bin and you can add this to your path if you like.
Confirmed by chrmhoffmann and committed. Thank you!
Thank you for this guide. I've compiled stuff before, but built my first Android from source last night. Although the build from that time has random reboots (the nature of the beast).
I'll be building quite a bit I think
Damn see I'm just porting right now I wanna build from source but my PC isn't Linux friendly yet I'm waiting on a tb internal so I can set up and learn this but it just looks so complicated and idk why. I feel once I learn it probably be easy as hell. Thanks Fattire

Hey congrats and welcome to the club!
Cannot Make the bacon...
Hey Fattire! Thank you for your guide. I was able to finally download the source for cm9 and add the 3.0 kernel repository. I have everything in one folder. I am new to Linux and had to add a Path command to get Repo Sync to work correctly. Once I got the Repos I ran into another problem trying to issue command cd ~/android/system/vendor/cm , then enter “./get-prebuilts”. The Make Bacon and or Croot <enter> brunch acclaim does nothing either. It seems I am missing somthing here. Maybe a different distro of Linux besides Mint would work better for me... getting close to building (i hope). Thanks!
I have to issue PATH=~/bin:$PATH every time I repo sync.

I use Ubuntu here I started with 10.04 LTS since it was the the build used and supported by Googles build instructions. Yous should still be able to do it though.
Did you initialize the build environment using ". build/envsetup.sh" at android/system (it looks like is the base of your source from your post)
Yes. Thank you for your advice KeithN. I am going to start from scratch. I might just put Ubuntu 10.04 on my comp tonight if I cannot get it to build properly.
I'm going for Ubuntu 12.04 command-line. If that doesn't go well, I'll go for 10.04 as well.
I built mine on 12.04 (Xubuntu, but that doesn't matter so much).
I added a debian sqeeze apt repository to get sun-java6-jdk, then used -f install when it complained because one of it's dependencies exists in Ubuntu but not that same version #. Commented out the repository after it installed so I don't get more debian packages on accident. For everything else I think it was just following the guide as-is.

Yes, I had recommended doing that. The PATH=$PATH:~/bin command will ensure that no matter what directory you type "repo", it'll know where to find the file.

Instead of entering it every time, you can add that PATH statement so that it's automatically invoked when you open a new Terminal window.
Just add the line to an "invisible" file (it's invisible because it starts with a period (.) and won't show up in a normal listing) called .bashrc in ~/.bashrc (the ~ is a shortcut for your home directory, or /home/youraccountname/). The hidden .bashrc file will probably exist already. Just add the statement to the end.

This is right. Try this:
$ cd ~/android/system
$ . build/envsetup.sh
(the $ represents the prompt and should not be typed. For the second command, it's literally a period followed by a space followed by build/envsetup.sh)
I am using the latest 12.04 ubuntu, fwiw.
I know this is for CM9, but any help would be appreciated (trying aokp). I had issues with the packaging of the .zip it looks like. I was able to build for my fascinate so I know the source will build. Any suggestions?
