Android 11 Build failed after changes in menuconfig

[abhiroopnray]

Hi

I am using Android 11.2.6.0. I have made changes in menuconfig to enable DM-Verity and copied the .config to imx_v8_android_defconf

Steps:

IN VENDOR/NXP-OPENSOURCE/KERNEL_IMX folder
1> export ARCH=arm64
2> export AARCH64_GCC_CROSS_COMPILE=/opt/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-
3> export CLANG_PATH=/opt/prebuilt-android-clang
4> make imx_v8_android_defconfig
5> make menuconfig ---> do your changes --> save changes
6> cp .config ./arch/arm64/configs/imx_v8_android_defconfig

But now I am getting this error when trying to build the kernel:

Command: ./imx-make.sh kernel -j4

But if I run make mrproper still the build is not getting successful.

It is showing error as below :
