Compiling frandom module for kernel 2.6.32.9

desalesouche · Feb 2, 2013

hi.
i would like to get some information about how to compile frandom module for my kernel.

here is the wiki... https://github.com/pier11/kernel_hu...-packing-the-kernel-into-a-flashable-boot.img
and git https://github.com/pier11/kernel_huawei_u8220
so which command i should use ? (i ve been told ---> CONFIG_*=m)
and when ?
i have the frandom kernel module tarball. dl it here= http://billauer.co.il/frandom.html
do i have to extract it? in which directory?
thank you very much...

as there is no teachers(for the moment) in that "university", i had to "harass" some regonized people from xda...(sorry for that)
and they kindly try to help me...
i had this kind of answer which i could do : i think that the following is to build the module included in the kernel..
Download Makefile, Kconfig, and frandom.c and put all three in your downloaded kernel source (drivers/char directory) overwriting any existing file.
this part is done...
but how to do that ? add FRANDOM=m to the kernel .config file ? and where is located that file?

2 minutes of googling suggests you take a look at these:

i have been googling far much more than 2 minutes and i already found these threads...but couldn't manage...
by egg with this one ...which contains error... http://yatsec.blogspot.co.uk/2011/01...om-kernel.html

PREPARING YOUR KERNEL SOURCE

First we must retrieve and copy the kernel config from our device.

Code:

$ cd /path/to/android-sdk/tools ----->ok
$ ./adk pull /proc/config.gz ----->not good! you have to make first $ adb devices in terminal....then $ adb pull /proc/config.gz

$ gunzip ./config.gz ----->ok
$ cp config /path/to/kernel/.config not working! ----> cp: cannot create regular file /path/to/kernel/.config : No such file or directory....
so what to do now?
how to solve this please? i will keep on googling to try to find out solution...any help is welcome
thank you
when i will finish my little project , i think that other people would benefit from that... i might make a how to .
for information ,i have been setting ubuntu 12.10 64 bits from this thread ---->http://soupdawg.wordpress.com/2012/...-for-building-android-jellybean-all-variants/

That's because you are meant to put in the path to your kernel, rather than literally /path/to/kernel...

@OP
I know you sent me a PM, but it's better if I reply here.
THIS is what did it for me. Of course my goal wasn't achieved as the extraversion bit was wrong. The X8 is a tricky device.
And make sure to go through the whole thread first.
And also try to use the arm-eabi toolchain from CM as that one throws the least errors.

hi all. i manage to compile the module thanks to Blechd0se http://xdaforums.com/member.php?u=4855459 i will soon edit the working how to kindly provided by him.
i thank all people who have been providing help and advices... and XDA

here are the change provided by bledchOse to be able to compile the frandom module for my kernel. and little how to
1---> https://github.com/pier11/kernel_hu...-packing-the-kernel-into-a-flashable-boot.img
2---> https://github.com/desalesouche/kernel_huawei_u8220
make the change in kernel before to build it ( change are in green)
3---> https://github.com/desalesouche/jordan-kernel/commit/52e4f2d00b2ea11e3643adb4c4235bdda7a87b5b
4---> Originally Posted by Blechd0se

And if you already compiled your kernel its inside the kernel, no need to compile another module which does exactly the same and you can instead push your kernel to your device "
5 build the kernel and or module and finish to follow explanation of link 1...
you will find the frandom .ko under drivers/char/frandom/ where your kernel is located... copy it under system/lib/modules/ in your rom zip.
you will need a script to make it load:be activated at boot

Et voilà!!!
