Cyanogenmod kernel config & davfs2 - General Questions and Answers

I'm going to create GREAT app, improve my java skill (It's almost 0, I'm C# lover).
For this I need to know which devices support FUSE and cross compile davfs2
Where is .config on cyanogenmod kernels?
Where to put .ko file in cyanogenmod?
Can I build davfs2 just by running this make -j8 --cross-compile="Linaro/Bin/arm-linux-"?

1. I don't know where you can find the config in the sources, but if you have CM running on your device, you can pull it from your phone
Code:
adb pull /proc/config.gz
and decompress the .gz file. Then open the config file with a texteditor.
2. .ko files are usually located at system/lib/modules/
3. sorry i don't know anything about davfs2
I hope this helped you a bit.

Are you a Windows user?
Kernels are always build with make.., at the command line.
BTW are you sure you will need to modify your kernel? to add a module, you don't need to recompile your kernel.
To edit your kernel, you just run make xconfig or make menuconfig and add/remove options.
Then save the config and run make

Any guides on how to create/compile custom roms?

I am a linux user...
Anyone can share the howto or if there are any guides?
+1 bumping this thread
Second that...

He seems to have a script to compile the Kernel...
I don't know to what extent this would help us but it is a start. I dont quite know how the apps are installed on a new ROM....
It would be nice if someone can explain what is needed and what is optional in the kernel and some of the mods that other people are doing and how they integrate in the OS.
I see a lot of improvements in the new ROM's but no how-to on doing it your self. I thought that was the point of having open source OS.
I would quite like this as well =o)
Have made a bit of a start by following this:
http://source.android.com/download
Shows you how to get all the code and do a build.
I believe the next thing would be to pick the required files from the output folder of the build, dump the boot.img and replace the kernel with 32B or 32A one, add the Magic model config file (to ramdisk) and recreate the boot.img
Replace/Add any modules required like maybe wifi or bluetooth, then need to change the build.prop file and put it all in to update.zip and sign the file.
Haven't had time to test this out but seems kind of logical...maybe?
Hello!
I'm following the android.com tutorial, but I want to ask: how can I download the donut branch? There's no mention in the entire site about it... Also, the cyanomod's multitouch and so on, where does it come from? Is it made by himself or it's somewhere in the net?
Thanks
Learn how to use GIT to get the donut branch from here: http://android.git.kernel.org/
Proble is that it doesn't specify the donut project path
Is there a command to list all project paths? I can't seem to find it

Ok, then so far I've downloaded the donut branch, and compiled too. What now?
1. how to create a ROM from the made files?
2. how to compile the kernel / how to replace the one created with the make command with the one I'm running on?
3. is there any option I can configure to fit my phone? (HTC Magic 32A)
4. how can I root my ROM?
thanks
there is this guide that i have found:

'make' finished with success but i can't find how to transform it into 'update.zip' file...

Xml read error

Well, not Sure if the past should be here, I think so.
*I was tinkering with a rom (Ledro id for desire), and wanted to take a look at the xml, in such framework-res.apk, but that open from the pc, I get: hexadecimal value 0x03 is an invalid character (with xml notepad). I still open it but it is unintelligible.
What are apk's trying to open with java (do not know if I have what it takes to open them) and that makes me: failed to load main-class manifest attribute ....
I just want to tweak a little, have if I learn slowly.
Sorry for my english I am from spain

XML files in apks are compiled to binary form, so you can't open them directly. You have to use some decoding tool: apktool (in my signature), Apk Manager (a wrapper around apktool) or AXMLPrinter2 (older and less powerful tool: can't rebuild XML and only partial info is decoded).
And no, you can't run apk files using Java on your PC.

[Q] how to compile libaudio.so module? [CM7]

Original post: forum.cyanogenmod.com/topic/41583-hello-hello-bug-cant-hear-caller/
It seems like I'm suffering from this bug
code.google.com/p/cyanogenmod/issues/detail?id=4681
although I found the commit
github.com/CyanogenMod/android_device_samsung_crespo/commit/49cb776c1a5d056c345d90465f8006ef23d947b0#libaudio/AudioHardware.cpp
which (hopefully) fixed this bug but the commit only merged into ics branch not gb branch (CM7).
I got cygwin and NDK set up, but I have no idea how exactly to compile libaudio.so module.
After selecting your target, enter:
Code:
make audio.primary.herring
from cygwin?
the target is the libaudio folder, right?
does it involve NDK?
I also need library file (libhardware_legacy.so, libcutils.so, libmedia.so, etc) isn't it? I have the files, where do I put those files?

Your target should be listed in the set of options before you begin building. In this case, it's crespo or crespo4g for the Nexus S or Nexus S 4G, respectively. If you need to build other modules, locate the Android.mk file for the module you want to build and locate the value under LOCAL_MODULE. The destination for the file(s) in question will be printed after the build is completed. What happens from there depends on what you intend to do with it.
Getting familiar with the build system will make things much more easier and faster for you in the long run.
Thanks for your guide.
Unfortunately, I still can't fully understand so I end up using the script provided by nicandris
forum.xda-developers.com/showthread.php?t=969266
instead of building the module, I build the whole rom.

[TOOL] Something to make BlobTools Easier to use

This tool is an interactive console application. It makes it easier to use blob tools. All you have to do is run it, choose to unpack or repack. If you choose repack it will ask you to enter the name for each of the required files. After that it will due the rest.
Notice: You either have to enter the full, have the blob file in the same directory/folder or have change changed directories to the location of the blob. For example: cd /path/to/blob's Dir/
Update: I have fixed the case sensitivity issue.
Note: The attachments below will always be the latest.

Sourcecode and Update
As I am unable to compile for Linux or mac at the moment here is the sourcecode for this tool.
This uses a Code::Blocks IDE for its project/workspace. It can be compiled with just a c++ compiler. The icon is only available on windows as I do not know to implement it on macosx and Linux does not support icons in executables. also, I have updated this application as well the updated binarie zip files and source zip are attached. Enjoy!

I tried to unpack a blob and it kept failing with an Invalid Option! error. I hit u then typed blob which was in the same directory. I then manually dragged the blob onto the blobunpack.exe and it unpacked it fine.
Any ideas why?

The blobs usually have no extension at all, and the extracted parts have a dot and the partition name as their last part, but I would not call these "extensions" (even if Windows disagrees with me).

Thanks, that makes more sense. Also, I am thinking about having BlobTools print the command usage in more detail or at least a "--help" command displaying detailed usage of BlobTools. Like, how to unpack and repack.

Is the blob you want to unpack in the same directory? If that does not work try adding a "." the end of the file name.

[Q] Boot.img?

Sooo yeah.... anybody got some help for this one? I have searched google and the forums but can't clearly figure this out, but how do I get a Boot.img for this phone??? I have rebuilt the kernel 3 or 4 different ways and the output never yeilds one, however I apparently NEED one so I can peel away the ramdisk x( any ideas?
EDIT: Okay, so now that I can compile a working stock kernel for the Sidekick, where should I start now? I know we already have a working voodoo lagfix kernel, but I want to make CWM for the stock kernel, that sounds like a good spot. And adding in init.d sounds like another good start. Making my own may help me in understanding it all. I AM taking notes too

If I recall correctly, I used the split_bootimg.pl script, and accompanying instructions, found here:
http://www.android-dls.com/wiki/?title=HOWTO:_Unpack%2C_Edit%2C_and_Re-Pack_Boot_Images
Start by unpacking and repacking a kernel that you already know is functional -- i.e. a copy of a kernel you have already successfully flashed. Once that repack can be flashed successfully, you can move on to making modifications to it, or packing a whole new initramfs and kernel.
I had to remove references to a few of Samsung's proprietary modules to get the kernel to build -- Samsung helpfully supplies the places for those sources to be put (IN TREE -- shame on you Samsung), but not the sources themselves. One such module was rfs, IIRC. I removed the Makefile references so I could finish a compile, then used copies of the compiled modules from an existing initrd. Where you run into compile failures, where the source code appears to be simply missing, this is probably the cause.
I found that I had to manually strip at least the modules that resulted when I built from sources, otherwise the finished image was far too large. Compare the sizes of your compiled kernel and module files to those of a known-working reference image. They should not be too far out of line.
I wish I had saved more notes from my own kernel builds. Regular Linux kernels are so easy, but earlier Android kernels are unnecessarily horrible to build. Still, if you run into any more issues, I'll try to help...
Oh, and please disable the keystroke logger!

Wow thanks nxd! I don't know if you have seen my other posts, but I'm a newbie at this stuff. Never too late to learn though right?
Now, as for the issues in the build, when I first tried to compile I was getting errors of an undeclared SEGMENT_SIZE in binfmt_aout.c so I searched around and was informed that the aout method is outdated? So I removed it from the config as instructed, seeing as it wasn't needed.
I've gotten to a compile resulting in the zImage and about 8 modules created. Now, the zImage is incomplete at this point if I am correct? If it's flashed, it will simply bootloop. (Because there is more to be done? i.e the ramdisk gz that loads the rom at the bootloader?)
Also, I will check the link about the logger, so I can disable it.
I appreciate all your help I really want to get this stuff down-pat eventually.

Correct, you need to put the modules onto an initramfs, and then assemble the zImage and initramfs into a boot.img. The URL I posted has instructions to both unpack and repack. I suggest that you obtain repack settings (command line, perhaps memory addressing) from an existing working image.
You can probably use the initramfs from an existing image as the basis for your new boot.img as well, replacing the modules from the old imitramfs with your new modules.

I hate to ask this because I'm afraid of being a pain in the a**.... but I hope you won't mind working with me, I'm in for the long run. Anyway, am I supposed to have a initramfs after the compile somewhere within the source? Or is this something I acquire from an an outside source? I promise I have done like 30-40 searches before hand. I have a feeling am missing something obvious -_-
Again, thank you for your generous help

The kernel compile will NOT produce an initramfs for you. It will produce the zImage (compressed kernel image) and modules.
The initramfs is an archive containing some files. During boot, when the kernel reaches the end of device initialization, it then creates an empty memory-backed filesystem, and extracts the initramfs contents into that new filesystem.
Ideally the initramfs would be generated by the Android build system, using the binaries produced by the kernel compile. But Samsung provides the bare minimum for GPL compliance, and so we don't get all the pieces we'd need for that. Presumably assembling those pieces is a big part of what windxixi has done, however.
When I worked up my boot.img, I used someone else's existing initramfs, dropped in my compiled modules and a few other minor changes, and then re-assembled it with my compiled zImage. If you're already working with windxixi's build kit and kernel sources, it might save you some time to use his initramfs as a basis for your own.
Really, once you've unpacked basically any SK4G boot.img, and extracted the files from the initramfs, I think you'll see the layout and that aspect the process will be clearer to you.

I haven't found any boot.img from another kernel, however I have finally figured out how to unpack the zImage D I think I'm a bit closer now, however, now I need to figure out how to un-cpio the initramfs.cpio and/or use the intramfs folder I now have. (in the unpacked zImage)
Then the next step I suppose would be learning how to incorporate the modules that I have. hmm..

On the page I linked to in my first reply, under "Alternative Method", those instructions worked for me to split, unpack, repack, and assemble. Did they not work for you?
Regarding how to incorporate the modules, you would copy them into the extracted directory in the same locations in the initramfs as the existing module files. Generally something like /lib/modules. Look for files ending in '.ko'. They may be spread out a bit in your compiled kernel sources, but they should all be in one directory in your extracted initramfs directory.
As for an existing boot.img, it's a Froyo kernel, but there's this: http://forum.xda-developers.com/showthread.php?t=1663622.

I tried this method of repacking, but so far I have not been able to re-pack my zImage successfully. (I feel pretty close to getting this) Maybe I am putting the modules in the wrong place? Or perhaps I am skipping a step. I believe I need to assign more room for the modules. I am getting the error that initramfs_cpio is too large.
My initramfs has 2 directories in it- and I created a folder within called lib and placed the modules in there... that may be the wrong way, but I don't think it changes the need for more room in the kernel. Something to do with padding values maybe? /:
Also, the script I am using for this is from JunYoung- it is repack-zImage.sh a tool for de-compiling and recompiling a zImage. That's how I got to my initramfs directory in the new zImage I built with the source.

I think your extracted initramfs should have more than two directories.
Would you paste a listing of the files and directories here? Do this:
Code:

EDIT: I also tested unpacking another zImage that is working, in fact I tried it on the Bali SK4G that we use currently (I hope that was okay with you /: I probably should have asked) but it just keeps displaying code as if it won't finish unpacking. It makes sense because there is a lot more to unpack, I think it is because it is compressed.

You don't need my permission to use my Bali-based Linux kernel image or patches.
Where can I get a copy of this other boot.img you're working with? It seems clear the hacks and workarounds I used with the Bali-era kernel don't translate directly across. I'd like to take a look and see what I can make of it.

Well, I never really found a literal "boot.img" from what I read I have to compile a zImage and in the sidekick's style system boots this as a boot.img??? And I have only used the one from kernel source so far, seeing as I could not get the Bali zImage to split.
As for the initramfs.cpio that us within the zImage, I tried to un-cpio it and I get an error about removing '/ from name?
I could send you the zImage I got from source o.e
EDIT: I never found a copy of boot.img, I couldn't even get one from an outer-source.

That's more of an advisory than an error. It's just telling you that it's stripping off the leading /, i.e. extracting to a relative path.
It sounds like you probably succeeded in extracting the initramfs.

Well, then that sounds better! But what about this one:
cpio: dev/console: Cannot mknod: Operation not permitted
1 block
I forgot there was a following error

You'll probably want to extract the files as root. Otherwise device nodes won't be created, like above, and permissions won't be kept on any of the files.
Be careful to be in a safe (i.e. empty) working directory when you do that. It will extract the files into your current working directory.

Okay so now after I execute as root, it gives me this message:
cpio: /dev/console not created: newer or same age version exists
So the directories are empty after extracted?

There's another argument you needed: --no-absolute-filenames
Unfortuantely it looks like cpio will have kept the absolute path and overwritten files on your real machine.
Extract into a directory using --no-absolute-filenames and see what files on your host system were overwritten. Those files should be recovered somehow before proceeding.
Sorry I didn't catch that.

Oh god -_- wow I messed up then. well....the only file that was within the cpio was a file named console.... so I think I need to fix that?
I'm not mad or anything, it's a risk you take ya know? But I may need help.
EDIT: Okay so I reboot my laptop and it reboot fine, no issues. I don't think it actually overwrote any file (luckily because that cpio file didn't have anything in it...heh) So should I now try the command with the new argument?

I'll take a look at the boot image this evening. It would seem very odd to me if the only file on the initramfs was /dev/console.
