How to link any library in ndk application
Solution 1:
when you get "make: * No rule to make target `something.c'", it just means it can't find the file.
I'm a bit confused why you've organized your project like that, but if I was going to build your project, I would do it as follows:
(doesn't matter which directory)
|
-->(ndk_demo)
-->-->(jni)
-->-->-->Application.mk
-->-->-->Android.mk
-->-->-->com_marakana_NativeLib.h
-->-->-->ndk_demo.c
-->-->(stackoverflow)
-->-->-->stackoverflow.h
-->-->-->libstackoverflow.a
Then I would use the following makefile:
Android.mk:
LOCAL_PATH := $(call my-dir)
### include stackoverflow as a prebuilt lib ###
include $(CLEAR_VARS)
LOCAL_MODULE := stackoverflow-prebuilt
LOCAL_SRC_FILES := ../stackoverflow/libstackoverflow.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/../stackoverflow
include $(PREBUILT_STATIC_LIBRARY)
### build your ndk lib ###
include $(CLEAR_VARS)
LOCAL_MODULE := ndk_demo
LOCAL_C_INCLUDES := $(LOCAL_PATH) \
$(LOCAL_PATH)/../stackoverflow
LOCAL_SRC_FILES := ndk_demo.c
LOCAL_LDLIBS := -llog
LOCAL_STATIC_LIBRARIES := stackoverflow-prebuilt
include $(BUILD_SHARED_LIBRARY)
And the following:
Application.mk:
APP_MODULES := ndk_demo
APP_PLATFORM := android-8
Then finally, I would navigate to the directory (ndk_demo) and run ndk-build.
ndk-build is android's build tool. You should use it. It can be found at:
(AndroidSDK)/(NDK)/ndk-build
if you are using windows, you will either have to type the full path of ndk-build into the console, or add an environment variable to your system before trying to run it.
