Problems compiling apps for Universal under Linux

Sorry for a lame question, but i've got a problem. I've compiled a simple hello-world application using arm-gcc 3.4.3 (compiled under x86 linux using gcc compiler for ARM) with default settings. When I was trying to start it under Universal, I got the message 'Invalid instruction' (or something like that).
Please provide me with a working example (command-line arguments for building and etc) or some instructions on build process, if anybody has one.
Thanks.

You don't tell where does the gcc-3.4.3 come from.
With the 3.4.1 stadalone toolchain from
ftp://ftp.handhelds.org/projects/toolchain
it is just
Code:
/usr/local/arm/3.4.1/bin/arm-linux-gcc -o hello hello.c
If you want to compile GUI apps or big packages, then you should read
http://www.openembedded.org/wiki/GettingStarted

I downloaded it from www.gnuarm.com. It worked OK when compiled ROM images for my ARM7TDMI-based boards.
Thanks for the link, I'll try it today.
And, finally, another lame question: did anybody tried to build gcc 4.1 for cross-compiling from x86 to ARM? Or it is possible to use the script from the FTP to build it?

Poking around the Source Code

I am trying to find information on how to poke around my own phone's source code (if possible, Sprint HTC Hero) and also the Android Source Code which is downloadable.
I'd like to see how the apps look, and how I could change them. I also want to know how to go about editing and loading that source code up on a phone.
Is this possible with my phone? Or do I need a special phone to do so? I'd like to know how these folks are going about creating these special ROMs for phones, and how someone can edit it to their liking, and then compile it for a specific device.

source.android.com is where you should find what you need.

I did find that, and it works someone, but the address isn't right, and for some reason I can't install an older version of Java on my Ubuntu VM. Maybe because it's 10.4? Has anyone else been able to download the source code via Google's instructions? On a newer machine?

If you add the Jaunty repositories to your sources.list file you should be able to download sun-java5-*
If i find the exact apt lines I will post them later.
Another thought - Switch to Debian Lenny - I switched from Ubuntu after I upgraded to 10.04 and absolutely hated 10, but I am loving Lenny.
EDIT:
add
deb http://us.archive.ubuntu.com/ubuntu/ jaunty multiverse
deb http://us.archive.ubuntu.com/ubuntu/ jaunty-updates multiverse
to your /etc/apt/sources.list
then do
apt-get update
apt-get install sun-java5-jre sun-java5-jdk

Thanks for the update, I'll try that and see how far I get.
From what I gathered, Ubuntu was the only supported Linux operating system that I'd be able to get the source code of Android for...
I understand that the size of Android is so massive, an organized way to download it is necessary, but why isn't this just simple like FTP access?

[REQ] Help me get european ROMS working on i9000N

Hi all,
Can someone with experience teach a Guatemalan electronics engineer (that's me ) who has worked for 15 years programming business and web apps mostly in C# how to build a kernel so that I can run my P1000N with european roms?
I have never worked with open source projects, but I'm willing to learn.
The first problem to solve is that when I flash a european rom I loose touch screen capabilities, so that points to a different driver being used.
Or maybe there is someone who can tackle this project?
Thanks!

first of all, which rom do you want to use?
is the source code for your device released?
do you have a linux workstation (virtual machine is enough)?
are you familiar with the linux terminal and its commands?

Yes, searched on http://opensource.samsung.com/ for P1000N and already downloaded.
It's the difference with european kernel.
On the readme it lists:
< Platform >
1. Get Android open source code
: version info - Android froyo 2.2 (android-cts-2.2_r2)
( Download site : http://source.android.com )
2. Get GT-P1000 open source code
: GT-P1000_OpenSource.zip
( Download site : http://opensource.samsung.com )
Unzip it, then you will see the file GT-P1000_Platform.tar.bz2 which includes the platform source code.
3. Overwrite GT-P1000 Platform OpenSource to the Android open source.
4. Unzip GT-P1000N_Platform.tar that comes from the Latin American version.
( You can find GT-P1000N_Platform.tar in the same directory with this README.txt . )
5. Overwrite GT-P1000N Platform OpenSource to the Android + GT-P1000(European) Platform open source code.
6. Run build_latin_n.sh user/eng
$ ./build_latin_n.sh user
$ ./build_latin_n.sh eng
< Kernel >
1. Get GT-P1000 open source code
: GT-P1000_OpenSource.zip
( Download site : http://opensource.samsung.com )
Unzip it, then you will see the file GT-P1000_Kernel.tar.bz2 which includes the kernel source code.
2. Unzip GT-P1000N_Kernel.tar that comes from the Latin American version.
( You can find GT-P1000N_Kernel.tar in the same directory with this README.txt . )
3. Overwrite GT-P1000N Kernel Open Source to the GT-P1000(European) kernel open source code.
4. Run build_kernel_latin_n.sh
$ ./build_kernel_latin_n.sh
* Output files
- Kernel : Kernel/arch/arm/boot/zImage
- module : Kernel/drivers/*/*.ko
* How to Clean
- run build_kernel_n.sh Clean
$ ./build_kernel_n.sh Clean
* How to make .tar binary for downloading into target.
- change current directory to Kernel/arch/arm/boot
- type following command
$ tar cvf gt-P1000N-kernel.tar zImage

I'll install a VM, is Ubuntu ok? or do you have suggestions of something that will work better?

Somewhat rusty...
So, I know what a kernel is but in Android what is refered as the Platform?
Thanks!

platform is for example android 2.2 froyo
and you are going to do exactly what uyou have read in this readme file its not so hard to do

Hi, did you manage to flash any Rom ?

can anyone give me a link to cm7 source for our galaxy y???

SOLVED
MODS please move to proper section so if anyone wants to compile cm7 they can easily find its sources
COMPRESSED CM7 SOURCES
finally after searching hard i found the sources
its compressed so it will be much more faster to download, posting it here if anybody else needs it

[Q] How do I keep the bèta and normal source codes seperated

Hello everybody!
I've been thinking a while of running my own bèta channel and decided to start one.
There is something that I've wondered, how do I keep the original and bèta code seperated?
Is there a sdk for a beta channel or do I need to use a private Github repository?
If yes, can somebody please tell me how I set it up?
I've been trying and dying to get Github work with Eclipse, but it doesn't work
Thank you in advance!

Git is definitely the best way to do this, basically make a beta and release branch. Switching between the two is really easy once you have it all setup.
What are the specific problems you have been having with Git?

I got GitLab instald on a local server and I have a beta ans a master branch. The problen with git is that i know the basics, push, pull, add and commit thats is. I really don't know how to seperate the code of different versions (eg v.1 and v.2) in the same branch.
Let me give another exame the GitLab is a wonderfull project, but I can't delete a folder (all the magic happens within a webinterface), but I can delete the files one by one ... Nope takes to much time
How do I manage files trough git, from my workstation (remove directory's for example)
Is there a guide about git somewere? When i search for it on Google all i get is github results but i want git results.
Thanks for helping me out!
Appriciate it!!

Why do you need GitLab? From your requirements you just need Git client and remote repository (which can be github.com).
You might want to check Git Branching - Basic Branching and Merging.

I wanted an east to use git software. When installing GitLab the setup setups everything for you, so I don't have to run commands etc. which saves me a great amount of time.
Thanks for the link, I'll check it out later today!

I see. Basically to get started with GitHub you just need Git package (e.g. msysgit for windows).

Yeah, I got GitLab installed on a networked server.
Can you learn me a few tips 'n tricks?

Sure, you can start from here: https://help.github.com/articles/good-resources-for-learning-git-and-github/

Thanks!
