Root Yet another "How-to" build, MTDEV style

[dsmryder]

As I sence a resergance in the desire to build ROMs from source, I decided to remake the HOW-TO. This is taken from the MTDEV website set up by g60madman. (Thanx Bra)

Developing can be adicting! It can also give you bags under your eyes, put an arch in your back, and give you carple tunnle syndrom. You have been warned!

Everything I put, in this post, into code boxes can be coppied and pasted. If I put it in a "notepad box" I am being more general and you will need to read what I am trying to get across. I can explain on later posts.
Some things to understand, if I use a dollar sign ($) it is run from the terminal as a normal user. If I use a pound sign (#) it is run from the root account.

First of all, all of my work is done on Ubuntu 10.04 64-bit desktop edition with a multi core and processor workstation with 8GB of RAM. It can be done on other versions of Linux, but I don't do it and will have trouble with helping you. I hope I don't need to help anybody setting the OS side of things.

After you set up the OS, you will need to prepare the system. Go to System->Administration->Software Sources. On the “Other Software” tab, check the box next to http://archive.canonical.com/ ubuntu lucid partner and close.

Now we can install the software to build and compile and whatnot.
Open a terminal. (ctrl + alt + t) and you will get a propt($).

We'll start with git. Git is a system for managing source codes that can work well in a bunch of way... anyway, we'll get to that.

sudo add-apt-repository ppa:git-core/ppa

This adds the repository so you can install it

sudo apt-get update

You will need to enter your passwod from time to time.
Now that your repositories have been updated, you can proceed with installing the required packages.

sudo apt-get install git gnupg flex bison gperf build-essential
sudo apt-get install curl zlib1g-dev libc6-dev lib32ncurses5-dev ia32-libs
sudo apt-get install pax11proto-core-dev libx11-dev lib32z-dev
sudo apt-get install libgl1-mesa-dev g++-multilib mingw32 tofrodos 
sudo apt-get install python-markdown libxml2-utils xsltproc
sudo apt-get install zip lib32readline5-dev

Then you will need to install Java 6 JDK

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jdk sun-java6-plugin
sudo apt-get install schedtool

Now you need to download the source for what you want to build.
First you will need to install "repo". It's a script that does a ton of work for you.
For that you need to make a directory for it under your account. I would highly recommend not working out of your ROOT account. It's very bad practice. Your propt should still be something like this[HIGH]user@computername~(current path)$[/HIGH]
the tilda (~) represents your home directory. Basicly /home/(user).
So make the directory

mkdir ~/bin

Then add the path to your variables

PATH=~/bin:$PATH

Sometimes this won't stick and you will need to modify your bash (the terminal you are working under) initiator script, .bashrc (the period os sopposed to be there). It's hidden from the gnome visability so if you are looking for it you will need to unhide it with (crtl + h). So at the bottom add [HIGH]export PATH=$PATH:/home/(user)/bin[/HIGH]
After setting that up

curl [URL="https://dl-ssl.google.com/dl/googlesource/git-repo/repo"][COLOR=#0066cc]https://dl-ssl.google.com/dl/googlesource/git-repo/repo[/COLOR][/URL] > ~/bin/repo
chmod a+x ~/bin/repo

Now you have all of the tools. The next part depends on what you want to work with. I'll use CM7 as an example. Make a "working directory" and change to it

mkdir cm7
cd cm7

Initialize the directory

repo init -u [URL="https://github.com/MTDEV-CM7/cm7.git"][COLOR=#0066cc]https://github.com/MTDEV-CM7/cm7.git[/COLOR][/URL] -b cm7

For CM7

repo init -u git://github.com/MTCM9/android.git -b ics

For CM9
And then download all that source code

repo sync

That part will take quite a while. I recommend doing it and going to bed.
When you wake up in the morning you should have no errors and will be able to build right away.

. build/envsetup.sh && brunch triumph -j'grep 'processor' /proc/cpuinfo | wc -l'

This sets up the enviroment and gets it running.
The "-j" part splits up the build into jobs for the system to run semi-simultaneously. The rest of that looks to see how many logicle processors you have and thus how many jobs the computer can run.

So there you have it. That should get things going. I hope people will ask lots of questions and we can hopefully move things along in 2013.

I don't know about you guys, but I like the monitor on my main rig, so I use Teamviewer to connect either with one of my computers or on my phone (Deving at work, WHAT!)

Enjoy!

When I do my FAQ update, I should probably add this if that's OK with you. Before it gets buried on the forums.

It's OK with me. I coppied a bunch from the MTDEV website. I just tried to make it semi general and thought that some of the community was thinking about it.

 

[g60madman]

dsmryder,

You may want to check out my updated environment setup, it has some extra stuff which allows the build to be optimized, and also a new version of git. So you will want to delete your bin folder in your home directory after updating it.

EnvironmentSetup - htc-evov4g - Setting up your Ubuntu 10.04 environment - Virgin Mobile HTC Evo V 4G Devlopment - Google Project Hosting

You also should be able to log into the MTDEV Wiki as I added you and the rest of Team MTDEV to update it. That includes you MikeRL

 

[dsmryder]

Ok, I just updated the tut to reflect the changes that g60 suggested and added the note on teamviewer.

 

[Ken2Chill]

Can I use this on ubuntu 12.10? or will I have to change things.

 

[dsmryder]

Can I use this on ubuntu 12.10? or will I have to change things.

Yeah, there's a lot of differences. Google has a setup for all of the versions. And there are some other things that are different. I would stay with 10.04 sense we know that works.

 

[dsmryder]

So today I decided to start over with my workstation. I am using the instructions that I have posted and will be testing it out personally.

Ubuntu is loading as I type and will continue on the workstation.

 

[Ken2Chill]

when ever i try to to install Java 6 JDK, it ask me if i want to [Y/n] I type in Y but it still aborts...

 

[chilz]

type the full word yes i have dealt with the same error

 

[dsmryder]

type the full word yes i have dealt with the same error

That's weird, I don't type anythin else other than "y". I leave it as a lower case and everything. In fact I just did it yesterday and it worked. Ken2Chill, are you using Ubuntu 10.04?

And I'm downloading the source now.

And I'm building it now

Yes... I'm dual booting it with windows 8. BTW my native Ethernet isn't working. Im tethering

The native ethernet may have a driver that's not open source or too new. Have you ran a search on it? The relaibility of cell data connections will almost ensure you will have errors and major headachs.

I've read on "dd wrt" but it seems that Ubuntu isnt even reading the router. ( it "Seems" like it, im fairly new to Linux and I'm using "network tools" to check it.) and im not ready to brick my routor it seems pretty difficult. oh and if you would like to check out my set-up and possibly help me troubleshoot, we can set up some kind of remote view. I know that you don't have much time on your hands...

 

[Ken2Chill]

Its still not working, I don't know what to do, I wanna learn to start building lol.

I PMed you.

I'm rockin linux mint 14. I'm actually really happy you guys use linux, as I have been using linux for well over 5 years, and know it better than any windows crap. Hope this works with all the ubuntu repo's you mentioned...

 

[DatNexus]

Hey DSM I already have openJDK 7. Will this work for all Java compilation/running needs?

 

[dsmryder]

I don't think so. If you go to the developement website, they specify Java 1.6. If you are working with FroYo and earlier, 1.5. Also, they keep a revision of the old (1.5 and 1.6) in some repos and have you setup access to them.

I know b_random14 was trying to use openJDK, though what version I don't know. I know he had some trouble with it. Maybe if he passes by he can comment on it.

 

[Ken2Chill]

I can get ethernet on peppermint os... so maybe its not linux?...

I decided to just get another HDD from the magical basement of magic and loaded it up with 10.04. BTW dsm, your huge install command did not work right. It only installed the first three packages. I had to install them all individually, but it did work after that. Also, where are the CM9 and CM10 repos? When I searched on Github all I found was an MTDEV CM10 repo that 404'ed when I tried to add it and a TON of CM9 kernels from both MTDEV and Mantera.

EDIT: NVM on the CM10, I got that working. I still cannot find the cm9 repo though.

I'll have to dig up the CM9 repo link. I know g60 deleted the one I was a part of, but I can redo it if nessacery.

Here you go

repo init -u git://github.com/MTCM9/android.git -b ics

Thank you! Sweet. What exactly should I do now that I have my repos synced? Where do I even start? So many folders lol.

 

[dsmryder]

Thank you! Sweet. What exactly should I do now that I have my repos synced? Where do I even start? So many folders lol.

The first thing I would do is just build a ROM with the code that's there. That way you know it works and have a base to start on. Also, do you know how to use git? If not look at my git and github questions thread.

Once you have an idea that you want to work with, just make a new branch and code away.
