Android NDK:包括 boost c++ 库 [英] Android NDK: Including boost c++ library
问题描述
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 这里 和这里,但我不能对我说同样的话.我特别想使用 此链接,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.
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.
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:
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
显然 cp: omiting directory...
并不是一个错误.但除此之外我唯一得到的是下一行,这并不意味着什么.错误 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
这是我的 Android.mk 文件:
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)
在path/to/ndk/sources/boost/
中还有一个Android.mk文件:
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)
还有我不起眼的 Application.mk 文件:
And my humble Application.mk file:
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.
I built the boost libraries using bjam
. All of the libboost_###.a
files are in the sources/boost/android/lib
folder.
我遇到的错误是什么?
推荐答案
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
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)
我使用一些 boost 库的模块看起来像这样
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)
此外,我有一个 Android.mk,其中列出了所有 subdir 生成文件
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
.
.
和我的 Application.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
