安卓 NDK : Including boost c++ library

Question

我正在尝试使用 NDK 在我的 android 应用程序中使用 boost 库。我发现了几个成功案例here和 here ，但我不能对我说同样的话。我特别想使用 this link 中的库，以及 boost 线程库。在下面的代码中，我只尝试包含线程库，而不是数学库。我用来构建 boost 库的过程与我附加的第一个链接几乎相同。

到目前为止，我似乎已经成功构建了 boost 库，但是当我运行 ndk-build 时，出现以下错误:

Prebuilt       : libboost_thread.a <= <NDK>/sources/
cp: omitting directory `path/to/ndk/sources/boost'
make: *** [obj/local/armeabi/libboost_thread.a] Error 1

显然 cp: omitting directory... 并不完全是一个错误。但除此之外，我唯一得到的就是下一行，这并不意味着什么。 错误1

这是我的 Android.mk 文件:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_STATIC_LIBRARIES := boost_thread
LOCAL_LDLIBS := lboost_system-gcc-md lboost_thread-gcc-md -lgnustl_static
LOCAL_LDLIBS += lboost_system-gcc-md lboost_thread-gcc-md \
         -L$(NDK_ROOT)/sources/cxx-stl/gnu-libstdc++/libs/armeabi \
         -lgnustl_static  
LOCAL_SRC_FILES := #cpp_sources
LOCAL_MODULE := com_example_ndkFile_CppMethods
include $(BUILD_SHARED_LIBRARY)
$(call import-module,boost) 

在path/to/ndk/sources/boost/中还有一个Android.mk文件:

LOCAL_PATH:= $(call my-dir)  
include $(CLEAR_VARS)  
LOCAL_MODULE:= boost_thread
LOCAL_SRC_FILES:= android/lib/libboost_thread.a  
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)  
include $(PREBUILT_STATIC_LIBRARY)

还有我不起眼的 Application.mk 文件:

APP_ABI := armeabi armeabi-v7a
APP_STL := gnustl_static
APP_CPPFLAGS = -fexceptions  

我使用 bjam 构建了 boost 库。所有 libboost_###.a 文件都在 sources/boost/android/lib 文件夹中。

我遇到了什么错误？

我使用 Boost-for-Android 构建了 boost 库.然后我在我的 boost/include/lib 目录中有 android makefile boost.mk

LOCAL_PATH := $(call my-dir)

# boost_date_time
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_date_time
LOCAL_SRC_FILES := libboost_date_time-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_filesystem
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_filesystem
LOCAL_SRC_FILES := libboost_filesystem-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_thread
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_thread
LOCAL_SRC_FILES := libboost_thread-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_system
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_system
LOCAL_SRC_FILES := libboost_system-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_program_options
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_program_options
LOCAL_SRC_FILES := libboost_program_options-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

# boost_chrono
#
include $(CLEAR_VARS)
LOCAL_MODULE := boost_chrono
LOCAL_SRC_FILES := libboost_chrono-gcc-mt-1_53.a
include $(PREBUILT_STATIC_LIBRARY)

我使用一些 boost 库的模块看起来像这样

LOCAL_PATH := $(call my-dir)

# SignalServer, executable 
#
include $(CLEAR_VARS)
LOCAL_CFLAGS           := -DTIXML_USE_TICPP
#LOCAL_CFLAGS           += -DDEBUG
LOCAL_STATIC_LIBRARIES := boost_thread \
    boost_system \
    boost_filesystem \
    boost_program_options \
    boost_chrono \
LOCAL_STATIC_LIBRARIES += ticpp \
    tia \
    tobicore \
    tobiid \
    tid \
    gdf
LOCAL_MODULE           := signalserver
LOCAL_C_INCLUDES       := $(LOCAL_PATH)/include
LOCAL_C_INCLUDES       += $(LOCAL_PATH)/extern/include
LOCAL_C_INCLUDES       += $(LOCAL_PATH)/../boost/include/boost-1_53
LOCAL_SRC_FILES        := #cpp source

include $(BUILD_EXECUTABLE)

此外，我还有一个 Android.mk，其中列出了所有子目录生成文件

TOP_PATH := $(call my-dir)

include $(TOP_PATH)/boost/lib/boost.mk
include $(TOP_PATH)/signalserver/signalserver.mk
.
.

还有我的 Application.mk:

APP_PLATFORM          := android-14
APP_ABI               := armeabi-v7a
#APP_OPTIM             := debug
#NDK_DEBUG             := 1

NDK_TOOLCHAIN_VERSION := 4.6
APP_STL               := gnustl_static
APP_CPPFLAGS          := -fexceptions -frtti
