I've got an issue building my C++ code using NDK r9d, since I try to compile C files using C++ compiler (G++) I've got this warnings :
C:/Android/ndk/build/core/build-binary.mk:393: warning: overriding commands for target
C:/Android/ndk/build/core/build-binary.mk:391: warning: ignoring old commands for target
Before I didn't need to compile with C++ 11 and my C files was compiled with GCC, I had no problems, but since I had LOCAL_CPP_EXTENSION := .cpp .c, this warnings appears (only for C files).
I found that someone else had the same problem (Overriding commands for target Android Makefile) but didn't get any answer.
Here is my files :
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
MY_INC_PATH := ../../..
LOCAL_MODULE := test
LOCAL_CFLAGS := -Werror
LOCAL_CPPFLAGS := -std=c++11
LOCAL_LDLIBS := -ldl -llog -lGLESv1_CM
LOCAL_C_INCLUDES := \
$(MY_INC_PATH)
MY_SRC_PATH := ../../../..
LOCAL_CPP_EXTENSION := .cpp .c
LOCAL_SRC_FILES := \
$(MY_SRC_PATH)/XXX.c \
$(MY_SRC_PATH)/YYY.cpp \
$(MY_SRC_PATH)/ZZZ.cpp
include $(BUILD_SHARED_LIBRARY)
I use NDK r9d and compile with G++ 4.8 and C++ 11 activated. Thanks for your help.
As of r9d, NDK does not provide methods to unassociate .c files from C compiler. You can redefine $$(TARGET_CC), and also set LOCAL_CFLAGS += -std=c++11, and not set LOCAL_CPP_EXTENSION to include .c, but that would be a hack, anyways. So if you cannot rename the files, and do not want to hack your NDK, the cleanest solution would be to simply ignore the warning.
