C++ 包括来自预构建库Android.mk的头文件

我已经在创建库时使用了一个预构建库

include $(PREBUILT_SHARED_LIBRARY)

是否包含已验证的天气库

$(modules-get-list)

当我试图在预构建的库中包含一个头文件时，我会遇到错误header not found。下面是我确切的Android.mk文件

LOCAL_PATH := $(call my-dir)

# import prebuilt-library
include $(CLEAR_VARS)
LOCAL_MODULE    := prebuilt-library
LOCAL_SRC_FILES := ../../../target/dependency/libs/$(TARGET_ARCH_ABI)/libprebuilt.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_SHARED_LIBRARY)

# building provider interface library for communication
include $(CLEAR_VARS)
LOCAL_MODULE := library-interface
LOCAL_SRC_FILES := LibraryComminicator.cpp
LOCAL_SHARED_LIBRARIES := prebuilt-library

include $(BUILD_SHARED_LIBRARY)

$(warning Existing modules: "$(modules-get-list)")

# Include the Android Maven plugin generated makefile
# Important: Must be the last import in order for Android Maven Plugins paths to work
include $(ANDROID_MAVEN_PLUGIN_MAKEFILE)

---

尝试下面的Android.mk：

LOCAL_PATH := $(call my-dir)
EXT_LIB_ROOT := $(LOCAL_PATH)/../../../target/dependency # or whatever

# building provider interface library for communication
include $(CLEAR_VARS)
LOCAL_MODULE := library-interface
LOCAL_SRC_FILES := LibraryComminicator.cpp
LOCAL_SHARED_LIBRARIES := prebuilt-library

include $(BUILD_SHARED_LIBRARY)

# import prebuilt-library
LOCAL_PATH := $(EXT_LIB_ROOT)
include $(CLEAR_VARS)
LOCAL_MODULE    := prebuilt-library
LOCAL_SRC_FILES := libs/$(TARGET_ARCH_ABI)/libprebuilt.so
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
include $(PREBUILT_SHARED_LIBRARY)

$(warning Existing modules: "$(modules-get-list)")

基本规则是：xxx\u INCLUDE\u文件应与“当前目录”相对，而LOCAL\u SRC\u文件与$（LOCAL\u PATH）相对，而不是与“当前目录”相对。对于NDK，“当前目录”通常是

$（本地路径）/…

，但这可能会改变，特别是当链接了Android.mk文件时，即一个文件包含另一个文件

对于预构建的共享库模块，您真的不需要本地路径，但我更喜欢将本地SRC文件尽可能短。

也许，您应该使用

LOCAL\u EXPORT\u C\u INCLUDES:=../../../../target/dependency/include

？@AlexCohn我已将其修改为包含头文件，但仍然是相同的结果，我的错。尝试

LOCAL\u EXPORT\u C\u INCLUDES:=$（LOCAL\u PATH）/../../../../../target/dependency/include

我实际上也尝试过，但结果仍然相同您能在磁盘上找到丢失的头文件吗？或者你可能不需要这个include？

LOCAL\u EXPORT\u C\u include:=/Users/rk/native test/apk solution/target/dependency/libs/include/com/raj/vs/ndktest/base

这个版本的C\u include可以正常工作，但在以下一个

EXT\u LIB\u ROOT:=../../../target/dependendency/libs LOCAL\u EXPORT\u C\u include:=$（EXT\u ROOT）/include/com/cnh/pf/activation/base include$（预构建的共享库）

是的，它失败了，因为正如我上面解释的，ndk构建的“当前目录”没有精确定义，通常是Android.mk文件上一级的项目目录（按照惯例，称为jni，由

$（调用我的目录）返回）

作为相对路径。因此，EXT_LIB_ROOT的定义可能应该是

$（LOCAL_path）/../../../../../target/dependency/libs

，但您可以通过将

$（warning LOCAL_path=$（LOCAL_path））

添加到您的Android.mk来轻松检查
