Android NDK: No rule to make target
I'm trying to build a simple Android application using NDK. Here are the contents of my Android.mk
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_LDLIBS := -llog
LOCAL_MODULE := myNDK
LOCAL_SRC_FILES := native.c
include $(BUILD_SHARED_LIBRARY)
And when I'm running ndk-build I get:
make: * No rule to make target
'/native.c', needed by
'/Users/ivan/Documents/workspace/TestNDK/obj/local/armeabi/objs/myNDK/native.o'. Stop.
So the problem is obviously that make is searching the source files in the root directory and if I copy native.c to my root folder everything works perfectly.
The question is: what should I specify in my Android.mk to set the LOCAL_PATH to my working jni folder.
OK, I've solved my issue, and the reason was very strange: the problem is in the first line
'LOCAL_PATH := $(call my-dir)____'
It had several spaces in the end (I've replaced them with '_'). If you remove them everything works just fine.
Hope that helps someone else.
On Mac OS X using android-ndk-r9 64 bit, remove white spaces from the NDK path. That fixed the No rule to make target error for me
Not exactly an answer for OP, but I guess it can save others from wasting their time.
Another problem that I found that causes this error is that the
LOCAL_SRC_FILES := native.c
and
LOCAL_MODULE := native
use the same name. I'm not sure why this causes an error, as the code should be generated in different locations as native.o, native.od, and native. But, apparently it does.
I found this out while trying to compile hello.c to hello. Once I changed hello.c to main.c, everything compiled properly.
