Building Android goldfish kernel with Ubunto 12.04.02 machine without success.

[ntt broken]

Hello,

 

i am trying to build without success the Emulator's kernel source code over Ubunto 12.04.02 machine installed on a VMware.

those are the commands i tried to follow using the 'official guide found here:

http://source.android.com/source/building-kernels.html

 

and others i found on the web:

could not find detailed resource with the complete working steps from a fresh ubunto machine to a working compiled kernel.

a video describing the process to follow would be great to have.

 

here are the detailed steps i did till i get errors:

I have the arm-eabi files as you can see below:

 

max@ubuntu:~/Maxdata/emulatorsource/goldfish$ ls /home/max/arm-eabi-4.6/bin/
arm-eabi-addr2line  arm-eabi-gcc-4.6.x-google  arm-eabi-objdump

arm-eabi-g++        arm-eabi-nm
arm-eabi-gcc        arm-eabi-objcopy

 

but when I try to do the cross compile it and/or make it give me errors:

 

max@ubuntu:~/Maxdata/emulatorsource/goldfish$ ARCH=arm CROSS_COMPILE=/home/max/arm-eabi-4.6/bin/arm-eabi-gcc make

max@ubuntu:~/Maxdata/emulatorsource/goldfish$

 

also tried to use the command with uImage mentioned in few places:

http://stackoverflow.com/questions/13864620/cross-compile-error-arm-android-eabi-gcc-command-not-found

 

max@ubuntu:~/Maxdata/emulatorsource/goldfish$ ARCH=arm CROSS_COMPILE=/home/max/arm-eabi-4.6/bin/arm-eabi- uImage make

and tried to have the toolchain properly declared as I read it can be relevant:

 

max@ubuntu:~/Maxdata/emulatorsource/goldfish$ sudo add-apt-repository ppa:linaro-maintainers/toolchain
[sudo] password for max:
You are about to add the following PPA to your system:
 Official backport of cross compiler from current Ubuntu release. Consists fresh gcc, binutils, eglibc.
Support provided for last LTS (12.04 Precise) and last stable release. Binaries for older releases will not be removed but also do not get any support.
Note that this toolchain defaults to ARMv7 with Thumb2. If you want to use it for older processors you have to add "-marm" into CFLAGS.
Remember to enable 'universe' part of Ubuntu distribution on your machine - otherwise you may get problems with solving dependencies (like it was with 'libmpc2' under Lucid).
To install latest version: apt-get install gcc-arm-linux-gnueabi (replace gcc with g++/gfortran/gobjc/gobjc++ if needed).

as you can see I have errors and I have no clue how I need to proceed to have the emulator’s kernel source build and compiled.

 

can you share your tell what am i missing? please be detailed in your answer so i will be able to take it and try.

 

THANK YOU!

add the compiler path to the $PATH environment variable

i know that compiler == gcc but which location i need to add?
I am not sure i know how to add it. sorry for my gap in knowledge.

at first, i tried below location without success:

$which gcc
/usr/bin/gcc
$ export CONFIG_PATH=/usr/bin/gcc

but the gcc mentioned in the error is "arm-eabi-gcc" which is think is different so this explains why it did not work.

also tried with other locations i can think:
$export CONFIG_PATH=/home/max/arm-eabi-4.6/bin/arm-eabi-gcc
$export CONFIG_PATH=/home/max/arm-eabi-4.6/bin/

those didn't help too.

if that helps, the currnet path:
 
$ echo $PATH
/home/max/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

thank you for your help!

try 

$ make ARCH=arm CROSS_COMPILE=/home/max/arm-eabi-4.6/bin/arm-eabi- 

try to understand what you're typing on the console.

Your first try:

$ ARCH=arm CROSS_COMPILE=/home/max/arm-eabi-4.6/bin/arm-eabi-gcc make 

I don't know where you learnt it, but you usually type make at the front. And CROSS_COMPILE=<your compiler prefix> is setting the

CROSS_COMPILE variable visible to "make", so is ARCH=<arch>

Don't put the extra gcc at the end of the cross compile.

CROSS_COMPILE=/home/max/arm-eabi-4.6/bin/arm-eabi-
