ndk-build 没有制定目标的规则

Question

This is my android.mk :

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

FREETYPE_SRC_PATH :=

LOCAL_MODULE := freetype

LOCAL_CFLAGS := -DANDROID_NDK \
-DFT2_BUILD_LIBRARY=1

LOCAL_C_INCLUDES := $(LOCAL_PATH)/include_all \
$(FREETYPE_SRC_PATH)include \
$(FREETYPE_SRC_PATH)src

LOCAL_SRC_FILES := \
$(FREETYPE_SRC_PATH)src/autofit/autofit.c \
$(FREETYPE_SRC_PATH)src/base/basepic.c \
$(FREETYPE_SRC_PATH)src/base/ftapi.c \
$(FREETYPE_SRC_PATH)src/base/ftbase.c \

LOCAL_LDLIBS := -ldl -llog

include $(BUILD_SHARED_LIBRARY)

And this is Application.mk :

APP_PLATFROM := android-20
APP_ABI := armeabi-v7a x86

After i hit ndk-build on the terminal Android Studio, i got an error message: make: *** No rule to make target '/app/src/main/jni/src/base/basepic.c

I've checked android.mk :

$(FREETYPE_SRC_PATH)src/autofit/autofit.c \
$(FREETYPE_SRC_PATH)src/base/basepic.c \

there is no whitespace. But still got an error.

Gradle model version=6.0.1, NDK version=21.1.6352462

I need to ndk-build without problem.. any i can do to solve this issue?

In your android.mk file you have FREETYPE_SRC_PATH empty. I guess it must be assigned as /app/src/main/jni/ .
