Error in Compiling 64-bit Neon code using Android NDK r10c

Parvathy Chandran

Hello, 

          I am trying to compile a 64-bit Neon code using android ndk-r10c in eclipse. I am getting an error message:

Android NDK: NEON support is only possible for armeabi-v7a ABI  its variant armeabi-v7a-hard and x86 ABI  

Android NDK: Please add checks against TARGET_ARCH_ABI in jni/Android.mk".

This is my Android.mk file

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_ARM_MODE := arm

LOCAL_ARM_NEON := true

LOCAL_MODULE := helloneon

LOCAL_SRC_FILES := helloneon.c

ifeq ($(TARGET_ARCH_ABI),$(filter $(TARGET_ARCH_ABI), arm64-v8a))

    LOCAL_CFLAGS := -DHAVE_NEON=1

ifeq ($(TARGET_ARCH_ABI),x86)

    LOCAL_CFLAGS += -mssse3

endif

    LOCAL_SRC_FILES += helloneon-intrinsics.c.neon

endif

LOCAL_STATIC_LIBRARIES := cpufeatures

LOCAL_LDLIBS := -llog

include $(BUILD_SHARED_LIBRARY)

$(call import-module,cpufeatures)

Can anyone help me in resolving this?

Thanks and Regards

    try this:

    ifeq ($(TARGET_ARCH_ABI),x86)

        LOCAL_CFLAGS    += -mssse3

        LOCAL_CPPFLAGS  += -mssse3

        LOCAL_CXXFLAGS  += -mssse3

    endif

    ifeq ($(TARGET_ARCH_ABI),arm64-v8a)

        LOCAL_CFLAGS    += -DHAVE_NEON64_or_Some_Other_flag =1

        LOCAL_CPPFLAGS  += -DHAVE_NEON64_or_Some_Other_flag=1

        LOCAL_CXXFLAGS  += -DHAVE_NEON64_or_Some_Other_flag=1

    endif

    ifeq ($(TARGET_ARCH_ABI),armeabi-v7a)

        LOCAL_ARM_NEON  := true

        LOCAL_CFLAGS    += -mfpu=neon

        LOCAL_CPPFLAGS  += -mfpu=neon

        LOCAL_CXXFLAGS  += -mfpu=neon

    endif

    ifeq ($(TARGET_ARCH_ABI),armeabi)

        #some fetchers for this arch

    endif
