Question

我有一个Application.mk和一个Android.mk文件。

Application.mk看起来像

NDK_TOOLCHAIN_VERSION := 4.8
APP_PLATFORM := android-9
APP_STL := c++_shared
APP_ABI := armeabi-v7a

我的Android.mk看起来像

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE    := foo1
LOCAL_SRC_FILES := foo1.cpp
# ... some other stuff ...
include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := foo2
LOCAL_SRC_FILES := foo2.cpp
# ... some other stuff ...
include $(BUILD_SHARED_LIBRARY)

现在我想库libfoo1使用c ++ _ shared for APP_STL而libfoo2使用c ++ _ static for APP_STL。（我知道，通常不应该relation between app_stl values with static and shared build android）。没有构建额外的项目并将库导入另一个项目是否有一种简单的方法？

是的，有可能。进行以下更改：

# Application.mk
APP_STL := none

这样就可以禁用选择NDK构建系统的STL实现的内部逻辑。现在，手动指定要与之链接的C ++ stdlib实现：

# Android.mk
LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE    := foo1
LOCAL_SRC_FILES := foo1.cpp
LOCAL_SHARED_LIBRARIES := c++_shared
# ... some other stuff ...
include $(BUILD_SHARED_LIBRARY)

include $(CLEAR_VARS)
LOCAL_MODULE    := foo2
LOCAL_SRC_FILES := foo2.cpp
LOCAL_STATIC_LIBRARIES := c++_static
# ... some other stuff ...
include $(BUILD_SHARED_LIBRARY)

$(call import-module,cxx-stl/llvm-libc++)

Android NDK：是否可以为多个库切换APP_STL？
