在Android中包括升压C ++库Android

我一直在试图结婚升压和Android在Windows上很长一段时间，并试图很多办法，但仍然没有运气。我想要使用Boost库在Android中的示例程序。我下面这个教程here.

I have been trying to marry Boost and android on windows for long time and tried lot of approaches but still no luck. I want to make a sample program using Boost library in android. I am following this tutorial here.

由于本教程建议我遵守了我升压lib目录中的 **（Android的NDK）\来源\ boost_1_44_0 ** 成功编译了。

As this tutorial suggested i have kept my Boost lib in **(Android NDK)\sources\boost_1_44_0** compiled it successfully.

这时我犯了一个 Android.mk 文件中的来源/ boost_1_44_0 并取得我想要使用的每个库的进入。在这种情况下的lib。文件的 libboost_date_time-GCC-MT-S-1_44.a 在现有的 boost_1_44_0 /安卓/ lib目录/ 这里是 Android.mk 文件的内容。

Then i made an Android.mk file inside sources/boost_1_44_0 and made the entry of each library which i want to use. In this case lib. file is libboost_date_time-gcc-mt-s-1_44.a available in boost_1_44_0/android/lib/ Here is the content of Android.mk file.

LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE:= boost_date
LOCAL_SRC_FILES:= boost_1_44_0/android/lib/libboost_date_time-gcc-mt-s-1_44.a
LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)
include $(PREBUILT_STATIC_LIBRARY)

现在，下一步是使 Android.mk 文件在我的项目目录，里面的 JNI 文件夹中。（这是创建一个共享库）。下面是它的内容。

Now the next step is to make an Android.mk file in my project directory, inside jni folder.(this is to create a shared library.). Here are its contents.

LOCAL_PATH := $(call my-dir)
 include $(call all-subdir-makefiles)

include $(CLEAR_VARS)

# Here we give our module name and source file(s)
LOCAL_LDLIBS := -llog -ldl
LOCAL_MODULE    := ndkfoo
LOCAL_SRC_FILES := ndkfoo.cpp
LOCAL_STATIC_LIBRARIES := boost_date
include $(BUILD_SHARED_LIBRARY)
$(call import-module,boost_1_44_0)

下面是Application.mk文件放在同一位置，里面的 JNI 文件夹。是Application.mk文件的内容如下：

Here is the Application.mk file placed on the same location, inside jni folder. Contents of Application.mk file are as follows:

APP_STL      = gnustl_static #(or APP_STL = stlport_static as required)
APP_CPPFLAGS = -fexceptions

最后，这里是我的 ndkfoo.cpp 文件

#include <string.h>
#include <jni.h>
#include <stdio.h>
#include <boost/date_time.hpp>

using namespace boost::gregorian;

void Java_com_ndkfoo_NdkfooActivity_invokeNativeFunction(JNIEnv* env, jobject javaThis) {
    date weekstart(2002,Feb,1);

}

此程序可能是不正确的，但问题是，它不承认任何boost头文件或功能。而我总是得到编译错误。

this program might be incorrect but the problem is that it does not recognize any boost headers or function. and i always get compilation error.

有我丢失的东西或做错误？任何帮助将是非常美联社preciated。

Is there something i am missing or doing incorrectly? Any help would be really appreciated.
