android - How to build for Qualcom Snapdragon 800 msm8974 chip on Samsung Note 3 -


hi have been working on compiling android image samsung note 3. downloaded source samsung, directed me download version of android open source project code. followed procedures in readme files provided. there discrepancies between procedures , tools used samsung vs. qualcomm's documents. question finding right procedure, , working image. have followed samsung's procedures, , have not resulted in working image of now. tried flash boot.img file created, , collected recovery logs posted here doing wrong though; not saying procedures wrong. here issues struggling with:

1- samsung's readme file says download arm-eabi-4.7, while qualcomm says used 4.8 compiler add on llvm. of now, plan try llvm 4.7 , 4.8 , see happens. have tried 4.7 w/o llvm , has not helped.

2 samsung procedures state update cross_compile statement path above arm-eaby-4.7 executable, export arch=arm, create config file following statement: 

make variant_defconfig=msm8974_sec_hlte_spr_defconfig msm8974_sec_defconfig selinux_defconfig=selinux_ defconfig

and run make. while qualcomm's llvm readme file states issue following command: 

ndk-build ndk_toolchain_version=snapdragonclang3.6 app_abi="armeabi-v7a" -c <some_project>

i know have have path ndk-build script , know is. not know is

1- if samsung's procedures run ndk-build also. looked through makefile in project's root directory , not see reference it. arm-eabi-4.7 run ndk-build perhaps?

2- best way working image me? not see ndk_toolchain_version , app_abi variables in samsung's .config file. can set these environment variables?

3- samsung's procedures state set environment variable of arch=arm, while qualcomm's configuration passed ndk-build armeabi-v7a

4- qualcomm's procedure calls project name. generic or find somewhere in samsung's files? did search in .config , makefile , did not see reference it.

5- there tags should add post attention of right folks know , deal questions mine stated above?

@jww - thanks. i'll try procedure, , going through material shared. hope can have other questions above addressed also.

update - hey noticed did not reply actual issue. question wanted ask if helps build image, provides more information wrong image? do via config command?
