How to set Build ID of a elf file in Android.mk -

-

i need set specific build-id elf file in android.

firstly,i use shell command this:

arm-linux-androideabi-gcc -pie -wl,--build-id=0xffffffff --sysroot /home/chengyi/code/android_6.0.1_bullhead/prebuilts/ndk/9/platforms/android-18/arch-arm main.c

readelf -n a.out.everthing ok.

above demo,i need set build-id in android.mk @ last.here android.mk:

    local_path:= $(call my-dir)     include $(clear_vars)      local_src_files:= \         main.cpp       local_shared_libraries := \         liblog \         libdl \       local_c_includes := \         $(local_path)/ \         bionic \      local_module:= a.out      local_cxxflags := \         -pie -wl,--build-id=0xffffffffffffffffff --sysroot /home/chengyi/code/android_6.0.1_bullhead/prebuilts/ndk/9/platforms/android-18/arch-arm \      include $(build_executable)

the output elf file has constant build-id,no matter how strive. there method set specific build-id elf file in android.mk?

thanks lot help.

if want set build-id android.mk. don't use variable local_cxxflags or local_cflags.

build-id sent linker,so need use local_ldflags this:

local_ldflags += -wl,--build-id=0xffffffffffffff
