Hi,

I have installed necessary packages and initiated build. After that, I got an error saying "libbpf: BTF header not found

I have initiated a fresh build again but build ran for few minutes and stopped. I am attaching the build-log file for reference. Kindly, help me with this issue. Thanks in advance.

Hi,

As it is saying need libbpf header, you need install libbpf-dev.

Hi,

I have installed libbpf-dev but still facing issue while building. I am attaching build-log file. Kindly, help me resolve this issue.

Other changes I have done 
1) In this path /home/sdv/Music/imx-automotive-14.0.0_2.3.0/android_build/vendor/nxp-opensource/kernel_imx/scripts/

inside file link-vmlinux.sh, commented below piece of code.

#if ! [ -x "$(command -v ${PAHOLE})" ]; then

# echo >&2 "BTF: ${1}: pahole (${PAHOLE}) is not available"

# return 1

#fi

2) In this path,/home/sdv/Music/imx-automotive-14.0.0_2.3.0/android_build/out/target/product/mek_8q/obj/KERNEL_OBJ/

Inside .config file,

changed CONFIG_DEBUG_INFO_BTF=y to # CONFIG_DEBUG_INFO_BTF is not set
changed CONFIG_DEBUG_INFO_DWARF5=y to # CONFIG_DEBUG_INFO_DWARF5 is not set

could you build android 14 successfully if you don't change anything? suggest you to build the android 14 without any modification, to improve your building environment is fine at least
