Building Kernel Image Issue

freewaymad — Wed, 14 May 2014 02:48:08 GMT

Hi,

I am getting this error and I don't know why. I am following the "Android User's Guide" for building a kernel. Here is what I am getting:

now@Here:~$ export PATH=~/mydroid/jb/bootable/bootloader/uboot-imx/tools:$PATH

now@Here:~$ cd mydroid/jb/kernel_imx

now@Here:~/mydroid/jb/kernel_imx$ echo $ARCH && echo $CROSS_COMPILE

now@Here:~/mydroid/jb/kernel_imx$ export ARCH=arm

make: *** [prepare0] Error 2

now@Here:~/mydroid/jb/kernel_imx$

What am I doing wrong? Am I missing something? I am using Ubuntu 14.04 and the JB4.3_1.1.0 GA source. Please help.

Thank you,

The Android project recommends using Ubuntu 12.04 64-bits, although only the 64 bits constraint is a must after Gingerbread.

Did you follow all the steps on the Android User’s Guide in order to install required packages and patches for our Android BSP? If so in which step are you finding this error? Sometimes it’s easy to overlook steps or packages like for example installing mkimage (command below)

$sudo apt-get install uboot-mkimage

That being said, it seems that the path to the toolchain is not being taken correctly. Please check this patch and make sure the files are there. If necessary, add to the .bashrc file.

Hi,

Yes I have all the right packages. I'll check path to the toolchain.

Thanks,

This case was that the path was not set correctly. Always double check the path.
