如何与Android的静态增强库链接？

Question

我有问题移植并使用Android-ndk-r5b将boost库链接到android.我首先使用以下步骤构建boost库(没有mpi,python):

1.在boost_1_46_0\libs\thread\build中注释第53行:

#   if [ os.name ] = "NT" { api = win32 ; }

2.在boost根目录中创建文件user-config.jam

androidNDKRoot = ../android-ndk-r5b ;

using gcc : android4.4.3 : $(androidNDKRoot)/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-g++.exe :
    --sysroot=$(androidNDKRoot)/platforms/android-3/arch-arm
    -mthumb
    -Os
    -fno-strict-aliasing
    -O2
    -DNDEBUG
    -g
    -fexceptions
    -frtti
    -lstdc++
    -I$(androidNDKRoot)/sources/cxx-stl/gnu-libstdc++/include
    -I$(androidNDKRoot)/sources/cxx-stl/gnu-libstdc++/libs/armeabi/include
    -D__GLIBC__
    -DBOOST_NO_INTRINSIC_WCHAR_T
    $(androidNDKRoot)/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-ar.exe
    $(androidNDKRoot)/toolchains/arm-linux-androideabi-4.4.3/prebuilt/windows/bin/arm-linux-androideabi-ranlib.exe
    linux
;

3.建立提升

bjam.exe --user-config=user-config.jam --without-python --without-mpi toolset=gcc-android4.4.3 link=static runtime-link=static target-os=linux --stagedir=android > d:\out.txt

4. Application.mk

APP_STL := gnustl_static
APP_PLATFORM := android-3
APP_CPPFLAGS += -mthumb
APP_CPPFLAGS += -Os
APP_CPPFLAGS += -fno-strict-aliasing
APP_CPPFLAGS += -O2
APP_CPPFLAGS += -DNDEBUG
APP_CPPFLAGS += -g
APP_CPPFLAGS += -fexceptions
APP_CPPFLAGS += -frtti
APP_CPPFLAGS += -lstdc++
APP_CPPFLAGS += -D__GLIBC__
APP_CPPFLAGS += -DBOOST_NO_INTRINSIC_WCHAR_T
APP_CPPFLAGS += -L/cygdrive/d/Android/boost_1_46_0/android/lib/

5. Android.mk

#   Howto
#   http://source.android.com/porting/build_cookbook.html
#

LOCAL_PATH:= $(call my-dir)

# ==============================================================
# libudt
# ==============================================================

include $(CLEAR_VARS)
LOCAL_MODULE            :=  libudt
LOCAL_C_INCLUDES        +=  /cygdrive/d/Android/boost_1_46_0/
LOCAL_SRC_FILES         +=  udt.cpp
LOCAL_STATIC_LIBRARIES  :=  boost_thread-gcc-mt-s-1_46

include $(BUILD_SHARED_LIBRARY)

6. udt.cpp

#include "boost/bind.hpp"
#include "boost/thread.hpp"

void thread_fn (int)
{
}

extern "C" int func1 ()
{
    boost::thread thrd (boost::bind (thread_fn, 1));
    thrd.join ();
    return 0;
}

7. $ NDK/ndk-build

我不知道你是否可以使用gcc，然后将静态库链接到Android平台。我所知道的是，一切都必须在NDK编译器下编译（因为指令集不同）。

你可以使用这个： https: //github.com/MysticTreeGames/Boost-for-Android ( .tar )

您将需要NDK 的定制版本。
