Hello everyone,

I just wanted to start a bit with "modding" my Acer Liquid A1 (:

As I just have less knowledge about everything, I stuck at the beginning ):

My running System is Ubuntu 10.10 64 Bit

My Equipment looks yet like this:

/Test/KernelSource/ <= KernelSource from Acer

/Test/arm-2010q1/ <= Compiler for ARM

But as I have found out here in the forum, the kernelsource is a little bit buggy, so I would appreciate every tip, as I really would like to get to know how to start and to begin with developing etc. (:

Enter the kernel source folder from shell and type

export ARCH=arm

export CROSS_COMPILER=/Test/arm2010q1

make

If there is any error, please post them

Thanks for help!

I've tried this:

marco@ubuntu:/Test/KernelSource/kernel$ export ARCH=arm

marco@ubuntu:/Test/KernelSource/kernel$ export CROSS_COMPILER=/Test/arm-2010q1

marco@ubuntu:/Test/KernelSource/kernel$ make

make: *** No rule to make target `.config', needed by `/config_data.gz'.  Stop.
and ('cause i've found this earlier on the web) 
marco@ubuntu:/Test/KernelSource/kernel$ export ARCH=arm

marco@ubuntu:/Test/KernelSource/kernel$ export CROSS_COMPILER=/Test/arm-2010q1/bin/arm-none-linux-gnueabi-

marco@ubuntu:/Test/KernelSource/kernel$ make

make: *** No rule to make target `.config', needed by `/config_data.gz'.  Stop.
Both are stopping here: 
marco@ubuntu:/Test/KernelSource/kernel$ make

make: *** No rule to make target `.config', needed by `/config_data.gz'.  Stop.

Seems that Acer removed the config file...run

make menuconfig
choose your config and, when you finish, run 
make
again Update: sorry, as you found in the web is 
export CROSS_COMPILER=/Test/arm-2010q1/bin/arm-none-linux-gnueabi-

marco@ubuntu:/Test/KernelSource/kernel$ make menuconfig

make: *** No rule to make target `menuconfig'.  Stop.
So that doesn't work =/ Then I searched the forum here and found this by errmsg: http://android.modaco.com/index.php?s=&amp...t&p=1600574
I have to disagree with you, defaults for .configs are taken from the configs dir, and in our case that's the file in arch/arm/configs/acer-q8k-a1-dvt_defconfig. So, I succeeded in cross-compiling the sources from acer with the following changes, copying the defconfig to ~/.config, applying the patch from http://paste.ubuntu.com/566676/ and running the build. Looks like Acer just physically removed some netfilter sources (and if they are added there then compilation breaks in more than one weird way) and released whatever they had.
So i've copied the /Test/KernelSource/arch/arm/configs/acer-q8k-a1-dvt_defconfig to /Test/KernelSource/kernel/.config and made the changes mentioned in the paste. But i get an error and google doesn't help me =/ 
marco@ubuntu:/Test/KernelSource/kernel$ export ARCH=arm

marco@ubuntu:/Test/KernelSource/kernel$ export CROSS_COMPILER=/Test/arm-2010q1/bin/arm-none-linux-gnueabi-

marco@ubuntu:/Test/KernelSource/kernel$ make

make: *** No rule to make target `FORCE', needed by `/config_data.gz'.  Stop.
This error has to do with these two "FORCE" mentioned in /Test/KernelSource/kernel/Makefile 
$(obj)/config_data.gz: .config FORCE

[...]

$(obj)/config_data.h: $(obj)/config_data.gz FORCE
but without "FORCE" I get (I don't know what this is, but it is a test worth :)) 
marco@ubuntu:/Test/KernelSource/kernel$ make

make: Nothing to be done for `/configs.o'.

Forget everything I have done before xD It was all wrong! ("cd kernel" was my fault)

Now I am at the next point:

My way of compiling it

marco@ubuntu:~/Test/KernelSource$ export ARCH=arm

marco@ubuntu:~/Test/KernelSource$ export CROSS_COMPILE=~/Test/arm-2010q1/bin/arm-none-linux-gnueabi-

marco@ubuntu:~/Test/KernelSource$ export CROSS_COMPILER=~/Test/arm-2010q1/bin/arm-none-linux-gnueabi-
