Android NDK: How to get compiler architecture in Android.mk dynamically

Question

I\'m trying to configure Android.mk to cross compile native code to support different chipset namely armeabi, mips, and x86. I know I can configure Application.mk in the fol

Answer 1

There is TARGET_ARCH variable that holds the value of the current ABI being built. You can use it the following way:

ifeq ($(TARGET_ARCH),x86)
    LOCAL_CFLAGS   := $(COMMON_FLAGS_LIST)
else
    LOCAL_CFLAGS   := -mfpu=vfp -mfloat-abi=softfp $(COMMON_FLAGS_LIST)
endif

If you specify APP_ABI := armeabi-v7a armeabi mips x86 or APP_ABI := all in your Application.mk you will get each and every separate ABI value.

Answer 2

Check TARGET_ARCH_ABI:

ifeq($(TARGET_ARCH_ABI), armeabi-v7a)
  # v7a-specific stuff
endif
