Include headers files location missing during the build process

[Raman Katwal]

Hi Team,

I am trying to build the ROM from AOSP Source based on 5.1.1.
Till now the build was going fine but now I am facing issue with compilation errors.

Command Used:

1)  source build/envsetup.sh 

2) lunch <option 7 for my device>

3) Build went fine for quite some time then file missing error. 

The QCOM stuff creating these error because each files in the folder hardware/qcom/display/msm8974 missing the reference to compiler header file/location.
So I don't want to amend each reference to point specifically. I know where the files are located but compiler not picking it up.

E.G: #include <media/msm_media_info.h>

All the stuff available on >> hardware/qcom/msm8x74

Can someone please guide me like which ENV variable I need to check?? or which .mk file I need to amend ??

You can get pass it by simply add to your BoardConfig.mk:
TARGET_BOARD_KERNEL_HEADERS := path/to/your/dirname/header-files
Or add to your device.mk:
TARGET_PRODUCT_KERNEL_HEADERS := path/to/your/dirname/header-files
Details in build/core/config.mk & product-config.mk
