Re: [android-building] building kernels problem: can't find bullhead_defconfig

bullhead is an arm64 device, you need to run:
export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-android-

[android-building] building kernels problem: can't find bullhead_defconfig

[Andrew Weiner]

Hello community,

I am trying to build the Android kernel following the instructions 
here: http://source.android.com/source/building-kernels.html
I am trying to build for a Nexus 5X so I've been using this row of the 
Kernels table:
bullhead device/lge/bullhead-kernel kernel/msm bullhead_defconfig

When I get down to this part 
[http://source.android.com/source/building-kernels.html#building], I run 
this command...
make bullhead_defconfig
...and I get the following error message:

***

*** Can't find default configuration "arch/arm/configs/bullhead_defconfig"!

***

make[1]: *** [bullhead_defconfig] Error 1

make: *** [bullhead_defconfig] Error 2

Indeed, when I have a look in arch/arm/configs, I see that there is no file 
called bullhead_defconfig.

Should I be using a different defconfig file?  If so, does the 
build-kernels documentation need to be updated?

I should mention that I checked out 
commit d28c62a152463152f5fbf84df30e1f0a68f2fc59 
(https://android.googlesource.com/kernel/msm.git/+/android-msm-bullhead-3.10-nougat-mr1.1)

Full disclosure, this is my first time working with the Android source, so 
please be gentle :)

Thanks!

Andrew
