Advantages of compiling code?

So recently i have gotten seriously interested in the behind the scenes work that our great devs do here. I want to become a dev. I searched Google for how to compile cm7 for my phone and i got to the wiki. But why? They have a cm7 build for my phone already. What's the point of compiling vs flashing atinm's? What can i do to make it better? Or more personal. I couldn't find any threads on xda about this. Also any guides you would recommend for a wanna be dev ?
Thanks guys

Here you can find everything you want know...

The point is to sync the source and snoop around and see how things work.
From there try and bring improvements and submit upstream.
Syncing/building is the first step.

For something like this, unless you want to hack CM or AOSP, you should just use the official CM builds that are published.

aosp kernals

so i finally did the dive for root and s off wow am i glad that i did... so my question is where are the aosp kernals aka cm7 miui i am wanting to flashing the up to date miui rom of miui.us but i am not seeing any kernals strictly for aosp roms or did i miss something thanks

There's only a handful of custom aosp kernels and a lot of them haven't been updated in a while.
Here's some links for a few

Also Sparksco has a few kernels here https://docs.google.com/document/pub?id=1kWewyOf4WYpeFwaeXtUG8kn6Xk_w_eG9Yv4-dNoQOlk
My personal favorite is Sparks pershoot kernel.

I'm also working on a few kernels as well... Atleast 1, hopefully 2 will be aosp, and hopefully the other will be ics sense (fingers crossed, its gonna be a lot of work)...

cool man thanks i can port all day long but don't know the first thing about making kernals out of my knowledge barrier..

HERE is a guide for compiling kernEls, made for our phone... It works... Trust me

KERNELS aren't bad once you know where in the source to find certain things that might need some tweaking to work on ported roms. Our phone uses the HTC-msm-7x30 and there's tons of msm-7x30 devices by htc out there that a lot of the hardware is the same. If you want to try and port a kernel just search github for msm-7x30. Only device specific things in the kernels are things like the hardware keyboard, camera/video drivers and things like that which you can find in toastcfh's kernel.

This is all correct... I'll also add that the G2/desireZ (vision) is almost the same as the shift, making it, for the most part, easiest to port. I highly recommend dl'ing Toastcfh's source and a few others (scary ghoul, sparksco, x99) so you can compare. It's convenient to have a solid source to look back on when you get compiling errors.

once we get kernel source, yes

We don't need kernel source to have that. Idk why people think we need source to do everything. The only good thing about kernel source is oc and uv

umm and libs and drivers aren't different between the tegra 3 and Snapdragon S4?

Yes they are but you don't need source. I come from the att note which doesn't have official ics or source and we had pa. Pa is a aosp rom like cm9 and aokp and we have both of those. Which shows kernel source is not needed
Sent from my HTC One X using xda premium

We don't need kernel source for the initial port, though we probably will to get the port bug free (for example, the CM9 build and multitouch).
I tried downloading the PA source a few days back but it kept erroring out (something about signatures not being trusted or something)
It might just be an SSL error on my PC, I'll have another go at it sometime soon. Seems like an intriguing ROM.

Yea its a cool rom. A team mate ported it to the note and its pretty bug free. I haven't looked at their sources lately but have they released source for pad?

if i can do anything to help please let me know, im more than happy to be a tester and provide bug reports/logcats or whatever. also thanks for the responses!
Sent from my HTC One X using xda premium

I'm sorry I've looked at paranoid android before and for some reason I was confusing it with Coredroid.
I haz a stupid.
However, kernel source will make building an AOSP kernel much easier. Right now we're using the One S kernel source and while it works for the most part, there are still some niggling issues as can be seen in the AOKP and CM9 threads.
But hell yeah build that thang!

Yea in that aspect source will be great but since the kernel for cm9 seems good it'll work for now. But if any one does do this good luck they put their code everywhere and if you miss one strand it won't work

tips?
if i was possibly considering the idea of maybe taking a stab at this port, anyone have any tips or good reference information? i have a little java experience but am comfortable with the SDK & adb and such.

learn how to build from source first
then learn how to merge cm9 commits into a local clone of paranoidandroid repo
then build it, and upload your device tree to git for others to work on

i727 ICS source now available

After lurking on Samsung open source for some odd weeks it looks as if the ICS source is available for the at&t galaxy s2 skyrocket.
go here and look for SGH-I727_NA_IC_Opensource.zip. As that is the source.

Bingo, ICS Platform and Kernel source.

We can finally get a tweaked out/more stable build :good:

touchwiz or aosp roms will benefit from this. This is the floodgates to lots of **** coming now. Most importantly though, I would expect us to go RC on CM9 very soon now.

Clarification
Well, reading the posts it seems there is general lack of understanding of the Android Kernel source tree. First of all if you look at all the Celox source tree released by Samsung (Kernel) there are all based of AOSP 3.0.8. This is little bit too late . Samsung already had the Celox sources released with SHV-E110S and T-989 last month. All the proper drivers for the SGH-I727 bit are already there in that kernel source.
I doubt, I will find any difference if at all there is any in this new source. (BTW, if people who have not developed kernels Sammy sources that they release are as ****ty as it gets, they NEVER release the manufacturing source, tell me I had to fix a crap load of stuff).
As far as Cymbaline, the source is now so far merged with upstream kernel sources (which is what one does, anyways) that it would be pointless for me to even consider starting with these source. And all those useless govs, bln, oc/uc tweaks are already there in my source tree ..And anyone who is making to attempt those will need to do it exactly the same places ....

Its called ChameleonOS, its essentially CM with a bunch of MIUI features like their theme engine, plus some new ones. Its still highly beta so watch out for issues. I believe blind is maintaining evita.
Its pretty cool Best part is that its open source unlike MIUI

Re: new rom not in our dev section?
Since I am the dev for MIUI and 0xD34D was a lead dev for MIUI, anyone that is affiliated with MIUI as a dev, gets first dibs on compiling. However, I have many other projects going all at the same time.. so if anyone wants to compile it for evita, have fun.

Re: new rom not in our dev section?
I tried chaos last night the 3/23 build. I was disappointed I couldn't get the latest jellybam 7.0 to boot up. It was exactly as rohan described it. Once they polish it up a little it should be a very interesting rom.

I'm not sure where you got that information but just because someone did work on a MIUI ROM does not mean they get dibs on compiling first. Evita is already officially supported by us so we'll be compiling nightlies and official builds. You can compile it if you like but I already have someone lined up to take the lead as the maintainer for evita.
I just wanted to add that although we reverse engineered the MIUI theme engine, everything else was developed from the ground up. If you've worked with AOSP or CyanogenMod then this will be easy to work with. Much better than the crap one has to deal with when porting MIUI without any source code. Trust me I did my fair share of porting MIUI and hacking smali and because of the frustration I had over how MIUI obfuscated everything I decided to come up with an alternative.

updated op. old builds in 0xD34D goo seem to have been removed, fresh builds are now in ChameleonOS goo.
