Question

当我尝试编译.so到bibiliotek时，我收到一个错误，说明方式不正确，而不是我期望的本地方式，我看到了NDK的方法，在什么问题，这里我的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)

这是我在输出中收到的：

Answer 1

cd到jni目录并致电ndk-build，这对我有用。

Answer 2

为了让(.git/hooks/pre-commit)指向正确的位置，您必须在pre-commit文件的顶部指定LOCAL_PATH，Android.mk不要清除include $(CLEAR_VARS)，请参阅documentation。

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。此变量必须保留其值，因为系统会解析所有变量都是全局的GNU Make执行上下文中的所有构建控制文件。

Answer 3

LOCAL_PATH := $(call my-dir)

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

正如@alijandro指出的那样， LOCAL _ 的长列表中明确缺少 LOCAL_PATH 。{/ 1}}重置了 LOCAL _ 。

为什么在Android.mk文件中$（调用my-dir）返回错误的路径？
