Hello.
I'm looking to compile iptables from the android git repo (with the LED trigger target patch). Hacking the source and patch was easy, but I'm not sure how to compile it. There's an Android.mk file in the source I pulled, but since it isn't structured like a JNI project, the NDK doesn't seem to help. Any suggestions on how I would go about compiling it?
I don't have much experience with the Android SDK and NDK (mostly do kernel hacking), and good ol' Google didn't help much either.
To run iptables you have to compile them in into the kernel or build as a kernel module. To do that you need to download the kernel for you specific device.
As for the actual iptables program, you can compile it using the agcc script. Since this site doesn't let new users to post the link just google for "vlad android-cruft" to find it.
PM me for details
Hello All,
I would like to use Iodine v4.0 on my android phone which is rooted with Cyanogen Mod 4.x, i tried statically compiling with arm-none-eabi-gcc but libz.a does not seem to come integrated into the ndk toolchain. iodine v5 is already available for android but due to version compatibility requirement for daemon and server i think i would definitely need to cross compile v4.0. could anyone cross compile it for android 1.6 ?
Link to Iodine v4 source: code.kryo.se/iodine/iodine-0.4.2.tar.gz
Thanks

Hi,
I really need the cp210x.ko module, but I couldn't successfully build it properly for my Iconia A500 with 3.2.1 and 2.6.36.3+ kernel.. I get the following when I tried insmod my cp210x.ko build using ubuntu cross compiler approach:
cp210x: version magic '2.6.36.3+ preempt mod_unload ARMv5 ' should be '2.6.36.3+ SMP preempt mod_unload ARMv7 '
A little search showed that I need to build it in ARMv7, and need to set the kernel config to build SMP kernel. In this thread I saw a few modules offered but couldn't post reply as a new xda-developers user, so I post here. My A500 has already been rooted via the su (version 3) method posted few days ago.
Please help me build the cp201x.ko module - I am kinda stuck..
Bill
Bill,
Might I suggest you look at loading one of the many custom ROM's that will have what you want? If you are rooted, then install CWM (ACER Recovery from the marketplace) which should allow you to load custom ROM's. In order to load the cp201x.ko module you'd have to recompile the kernel and people doing this type of work normally are building custom ROM's.
Anyway, just my 2¢
Thanks for the advice. I am testing Thor ROM at the moment. Cool..
From what I can read and see within various ROMs /system/lib/modules, very few (out of total possible) kernel modules made it to these custom ROMs - mostly to get game controller to work, extra filesystems, or networking protocols. USB-to-serial modules are rare and certainly my search didn't turn up cp210x.
Cross-compiling the kernel source on Gentoo is mentioned to be better supported then ubuntu, due to its crossdev toolkit, as I'm trying to figure out how to specify target ARMv7 instead of ARMv5 I'm defaulting to when cross compiling from Ubuntu's arm-linux-gnueabi-*
I'm wondering if various nice ROM cooks have releases of their modified kernel source - or might be willing to help me build the just the cp210x as a .ko module, e.g. in the .config, "CONFIG_USB_SERIAL_CP210X=m" - I've found a post few months ago where a successful build and insertion of cp210x module was done but he had some problems when initiating communication on it - I fear the worst but hope for the best, and would like to try that myself as I've successfully talked to my device through the cp210x module on Linux.
Or, if any tips on how to build kernel (just the modules really) properly e.g. As Thor's ROM version number hints at need for some custom and virtualized build environment, I'm looking for the quick and dirty solution if cooking ROMs/kernel/ko's has steep learning curve..
Any help much appreciated!
Bill
It looks like I was speeding down the the wrong track last few days
Apparently the /proc/config.z copied off the a500 device was missing something - and how strange that is - so I had to enable SMP and choose Tegra 2 ARM processor using "make menuconfig" to get the vermagic on the build module (e.g. modinfo after successful make modules) to show ARMv7 and SMP, build from my Ubuntu cross-compiling setup. I haven't tested this new cp210x.ko on a500 yet (as it's currently running one of the customized ROMs that has different EXTRAVERSION/vermagic to the stock Acer kernel source version 2.6.36.3 that I'm based on.
I think it'd be really wonderful if various Android kernel and kernel module makers release their kernel config, sync'ed to each ROM or kernel release, so people like me may independently build special purpose kernel modules with more efficiency and accuracy (to target their customized kernel), and we can recontribute back to to a growing list of tested and working modules for corresponding devices.
Bill
Hmm... Silly. It looks like Thor's ROM already has cp210x build-in, not as a loadable module but compiled in. My device is reported to attach to ttyUSB0! How nice
Thanks!
Bill
For those who are interested, the cp210x.ko module build using latest mentioned approach, e.g. modified kernel config.z, generate module that appear to insert correctly into lightspeed and taboonay roms (neither has this USB-to-serial module) - with a little modification of the EXTRAVERSION variable in the Makefile.

CP210x and GT-P7500
Has anyone got CP210x module working with Samsung Tab GT-P7500? My problem is that the connected USB-device doesn't create node dev/ttyUSB*. I have spent lot of time trying to figure this one out.
I have tried 1) Manually compiling the linux kernel that has cp210x support as a module. After compiling the module I tried insmoding the cp210x.ko to a running kernel, but even though it seemed to load and unload all right, it did not give me the wanted results. It does not create device node /dev/ttyUSB*. I have also tried modifying ueventd.rc for adding this row, but I am guessing it is only relevant for permissions after the node is created.
Also 2) loading cyanogenmod 10 (which should have cp210x support) to tablet but it doesnot create the desired /dev/ttyUSB* node. I can see device file under dev/bus/usb/001/ but the node does not exist.
I am going to try making needed files for building custom kernel and inserting to tablet. However, I have 0 experience on this, I think it can be tough one.
Any help would be welcome, thanks.
Here is an update to 'agcc' wrapper originally written by Andrew Ross. You can find his original version here.
Modded/Updated agcc
Helps you to quickly compile native C code for ARM, MIPS or x86 targets. I updated 'agcc' to try out a few existing exploits on Android, in hope of finding a few more to open up root for my new phone.
I thought some of you may find this updated script useful for compiling native code. I have tested these changes only on a Windows machine using Android NDK r8b.

I work for a company that is going to deploy a bunch of the BT-2000 glasses, and I've hit a wall when trying to implement an OpenVPN based client software, the problem is the stock kernel does not have the tun.ko kernel module built in. I've tried to contact Epson support about this as I know that other 4.0.4 devices did have this built in years ago but they are no help. It seems that I have no access to the kernel sources and no way to even install a custom kernel like I would on a nexus device. Any suggestions?
