android - 为什么 Android.mk 文件中的 $(call my-dir) 返回了错误的路径？

Question

当我尝试将 .so 编译为 bibiliotek 时，我收到一条错误消息，指出方式不正确，而不是我期望的本地方式，我看到了一种通往 NDK 的方式，问题出在我的 MK 文件上:

include $(CLEAR_VARS)

LOCAL_PATH := $(call my-dir)
@echo "Local path = $LOCAL_PATH"

SCRIPT := $(LOCAL_PATH)/LuaJIT/build.sh
ECHO_RESULT1 := $(shell $(SCRIPT))
#ECHO_RESULT := $(shell ($(LOCAL_PATH)/LuaJit/build.sh))
@echo "ECHO_RESULT1=$(ECHO_RESULT1)"

include $(CLEAR_VARS)
LOCAL_MODULE    := libluajit
LOCAL_SRC_FILES := $(LOCAL_PATH)/jnlua/src/libluajit.a
include $(PREBUILT_STATIC_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE := libjnlua
LOCAL_C_INCLUDES += $(LOCAL_PATH)/LuaJit/src
LOCAL_SRC_FILES := $(LOCAL_PATH)/jnlua/src/jnlua.c
LOCAL_LDLIBS := -llog
LOCAL_CFLAGS := -O2 -Wall -DLUA_COMPAT_ALL
#LOCAL_SHARED_LIBRARIES := libjavavm 
LOCAL_STATIC_LIBRARIES := libluajit

# POSIX as we're on linux, and compatibility mode in case you'll be running scripts written for LUA <5.2

include $(BUILD_SHARED_LIBRARY)

我在输出中收到:

cd 到 jni 目录并调用 ndk-build，这对我有用。
