问题描述

我想使用升压库在我的Andr​​oid应用程序，使用NDK。我已经发现一对夫妇的成功案例<一href="http://www.$c$cxperiments.com/android/2011/05/tips-tricks-building-boost-with-ndk-r5/comment-page-1/#comment-336">here和这里，但我不能说同样的我。我特别想利用图书馆的<一个href="http://www.boost.org/doc/libs/1_35_0/libs/math/doc/sf_and_dist/html/math_toolkit/toolkit/internals1/roots2.html">this链路时，以及升压线程库。在下面的code，我只是想包括线程库，而不是数学库。我用来构建Boost库的过程是pretty的一样一样的我附上一个链接。

到目前为止，似乎我已经成功地构建了boost库，但是当我运行 NDK建造，我得到以下错误：

  prebuilt：libboost_thread.a＆LT; =＆LT; NDK＆GT; /来源/
CP：忽略目录`路径/到/ NDK /来源/升压
使：*** [OBJ /本地/ armeabi / libboost_thread.a]错误1

显然， CP：省略目录... 不完全是一个错误。但我发现了比其他的唯一事情是下一行，这并不真正意味着什么。 错误1

下面是我的Andr​​oid.mk文件：

  LOCAL_PATH：= $（叫我-DIR）
包括$（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 $（NDK_ROOT）/来源/ CXX-STL / GNU-的libstdc ++ /库/ armeabi \
         -lgnustl_static
LOCAL_SRC_FILES：= #cpp_sources
LOCAL_MODULE：= com_example_ndkFile_CppMethods
包括$（BUILD_SHARED_LIBRARY）
$（呼叫进口模块，提升）

和另外还有在Android.mk文件路径/要/ NDK /来源/升压/ ：

  LOCAL_PATH：= $（叫我-DIR）
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_thread
LOCAL_SRC_FILES：=机器人/ lib目录/ libboost_thread.a
LOCAL_EXPORT_C_INCLUDES：= $（LOCAL_PATH）
包括$（preBUILT_STATIC_LIBRARY）

和我的卑微Application.mk文件：

  APP_ABI：= armeabi armeabi，V7A
APP_STL：= gnustl_static
APP_CPPFLAGS = -fexceptions

我用的bjam 内置升压库。所有 libboost _ ###。一个文件在来源/升压/安卓/ lib目录文件夹。

什么是我得到的错误？

解决方案

我建立使用升压换安卓Boost库。然后，我在我的升压/有/ lib目录下生成文件的android boost.mk 

  LOCAL_PATH：= $（叫我-DIR）

＃boost_date_time
＃
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_date_time
LOCAL_SRC_FILES：= libboost_date_time-GCC-MT-1_53.a
包括$（preBUILT_STATIC_LIBRARY）

＃boost_filesystem
＃
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_filesystem
LOCAL_SRC_FILES：= libboost_filesystem-GCC-MT-1_53.a
包括$（preBUILT_STATIC_LIBRARY）

＃boost_thread
＃
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_thread
LOCAL_SRC_FILES：= libboost_thread-GCC-MT-1_53.a
包括$（preBUILT_STATIC_LIBRARY）

＃boost_system
＃
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_system
LOCAL_SRC_FILES：= libboost_system-GCC-MT-1_53.a
包括$（preBUILT_STATIC_LIBRARY）

＃boost_program_options
＃
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_program_options
LOCAL_SRC_FILES：= libboost_program_options-GCC-MT-1_53.a
包括$（preBUILT_STATIC_LIBRARY）

＃boost_chrono
＃
包括$（CLEAR_VARS）
LOCAL_MODULE：= boost_chrono
LOCAL_SRC_FILES：= libboost_chrono-GCC-MT-1_53.a
包括$（preBUILT_STATIC_LIBRARY）

和我的模块在这里我使用一些Boost库的看起来像这样

  LOCAL_PATH：= $（叫我-DIR）

＃SignalServer，可执行
＃
包括$（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）/包括
LOCAL_C_INCLUDES + = $（LOCAL_PATH）/ EXTERN /包括
LOCAL_C_INCLUDES + = $（LOCAL_PATH）/../升压/有/升压1_53
LOCAL_SRC_FILES：= #cpp源

包括$（BUILD_EXECUTABLE）

除了我，所有子目录makefile文件中列出的Andr​​oid.mk 

  TOP_PATH：= $（叫我-DIR）

包括$（TOP_PATH）/boost/lib/boost.mk
包括$（TOP_PATH）/signalserver/signalserver.mk
。
。

和我Application.mk：

  APP_PLATFORM：=机器人-14
APP_ABI：= armeabi-V7A
#APP_OPTIM：=调试
#NDK_DEBUG：= 1

NDK_TOOLCHAIN​​_VERSION：= 4.6
APP_STL：= gnustl_static
APP_CPPFLAGS：= -fexceptions -frtti

I am trying to use a boost library inside my android application, using the NDK. I have found a couple of success stories here and here, but I can't say the same about me. I am specifically trying to use the library in this link, as well as the boost thread library. In the code below, I am only trying to include the thread library, not the math library. The process I used to build the boost libraries is pretty much the same as the first link I attached.

So far, it seems I have successfully built the boost libraries, but when I run ndk-build, I get the following error:

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

Obviously the cp: omitting directory... is not exactly an error. But the only thing I'm getting other than that is the next line, which doesn't really mean anything. Error 1

Here's my Android.mk file:

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)

And there's also an Android.mk file in path/to/ndk/sources/boost/:

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)

And my humble Application.mk file:

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

I built the boost libraries using bjam. All of the libboost_###.a files are in the sources/boost/android/lib folder.

What is the error I'm getting?

解决方案

I built the boost libraries using Boost-for-Android. Then I have in my boost/include/lib directory the 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)

and my module where i use some of the boost libraries looks like this

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)

in addition I have an Android.mk where all subdir makefiles are listed

TOP_PATH := $(call my-dir)

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

and my 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
