Android NDK：包括boost c ++库

Question

我正在尝试使用NDK在我的Android应用程序中使用boost库。我找到了几个成功故事here和here，但我不能对我说同样的话。我特意尝试在this link中使用库，以及boost线程库。在下面的代码中，我只是尝试包含线程库，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，似乎我已经成功构建了boost库，但是当我运行ndk-build时，我收到以下错误：

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...并不是一个错误。但我唯一能得到的就是下一行，这并不是什么意思。 Error 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)

还有我卑微的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。

我得到的错误是什么？

我使用Boost-for-Android构建了boost库。然后我在我的boost / include / lib目录下有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)

和我使用一些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)

另外我有一个Android.mk，其中列出了所有subdir makefile

TOP_PATH := $(call my-dir)

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

和我的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

在这里：http://silverglint.com/boost-for-android/你可以找到一个简单的脚本，让你为Android构建一个现代版本的boost，或者只是下载预建的boost二进制文件。

还包括一个示例测试应用程序，它向您展示如何包含/链接boost标头/二进制文件
