我正在尝试使用NDK在我的Android应用程序中使用boost库。我找到了几个成功案例here和here,但我不能对我说同样的话。我特意尝试使用this link中的库,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)
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)
我简陋的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
个文件都在sources/boost/android/lib
文件夹中。
我得到的错误是什么?
答案 0 :(得分:12)
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
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)
和我使用某些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,其中列出了所有子目录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,向您展示如何包含/链接boost标头/二进制文件
