[android-building] building kernel

[sachin verma]

Hi,

I am building kernel for android-msm-wahoo-4.4-pie-qpr2, After repo sync I run build/build.sh command from root and getting following error.(I have already installed libssl-dev). Any ideas on how to compile the kernel(Any setup If I am missing?)

 Setting up for build

+ make CC=clang HOSTCC=clang O=/home/e01066/AOSP10/KERNEL/out/android-msm-wahoo-4.4/private/msm-google mrproper

I continued to try and able to build the kernel by installing some additional libraries.

libc6-dev
gcc-multilib

But I wanted to enable kernel debug messages, can any one tell where is debug level configurations.

Thanks,
