This was due to a wrong vendor blob . deleting that from vendor folder solved it .

it was my mistake ,
initially when i run the

mka mkbootimg

I got this error

error: vendor/xiaomi/whyred: MODULE.TARGET.SHARED_LIBRARIES.libsdm-disp-vndapis already defined by vendor/xiaomi/whyred.

To resolve this I commented out those modules from vendor/xiaomi/whyred/Android.mk .

I accidentally commented out libantradio module too .

undoing that resolved the issue .

how to resolve this issue ??

This was due to a wrong vendor blob . deleting that from vendor folder solved it .

I was following UBport documentation https://docs.ubports.com/en/latest/porting/build_and_boot/H9_build.html

upto "Modify the kernel configuration" everything was fine .
Following command
./halium/halium-boot/check-kernel-config kernel/xiaomi/whyred/arch/arm64/configs/whyred-perf_defconfig

gives "Config file checked, found no errors."

but in next step "Build"
when i run the following command "mka mkbootimg"

i am getting this error
