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，而不是我所期望的本地方式，我看到了 NDK 的方式，这是什么问题，这里是我的 MK 文件：

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)

在这里我收到一个输出：

LOCAL_PATH := $(call my-dir)

必须是您的Android.mk文件所做的第一件事。此调用提取最新包含的 makefile 的路径，之后include $(CLEAR_VARS)，它将获取$(CLEAR_VARS)文件的路径（ndk/build/core）而不是您的jni目录。

正如@alijandro指出的那样，LOCAL_PATH明确地不在 由.include $(CLEAR_VARS)

cd 到jni目录并调用ndk-build，这对我有用。

为了让LOCAL_PATH指向正确的位置，您必须在Android.mk文件顶部分配，之前include $(CLEAR_VARS)，CLEAR_VARS不清楚LOCAL_PATH，请参阅文档。

CLEAR_VARS 变量指向一个特殊的 GNU Makefile，它为您清除许多 LOCAL_XXX 变量，例如 LOCAL_MODULE、LOCAL_SRC_FILES 和 LOCAL_STATIC_LIBRARIES。请注意，它不会清除 LOCAL_PATH。该变量必须保留其值，因为系统在一个所有变量都是全局的 GNU Make 执行上下文中解析所有构建控制文件。
