我正在尝试为使用Boost库的代码创建一个CMake项目。我想为Android构建它,我使用这个项目作为参考:https://code.google.com/p/android-cmake/。
我想使用之前为android构建的Boost静态库,而不是让它们成为要编译的项目的一部分。
这是我使用Boost
的项目部分的CMakeLists.txt#BOOST
set(BOOST_ROOT /home/neb/workspace/SDLActivityCMAKE/jni/boost)
set(Boost_INCLUDE_DIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/include/boost-1_53)
set(BOOST_INCLUDEDIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/include/boost-1_53)
set(Boost_LIBRARY_DIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/lib)
set(BOOST_LIBRARYDIR /home/neb/workspace/SDLActivityCMAKE/jni/boost/lib)
set(Boost_USE_STATIC_LIBS ON)
set(USE_STATIC_BOOST ON)
set(Boost_USE_STATIC_RUNTIME ON)
set(BOOST_COMPILER gcc)
find_package(Boost COMPONENTS "thread-gcc-mt-1_53" "date_time-gcc-mt-1_53" REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIR})
#BOOSTEND
add_executable(main main.cpp)
target_link_libraries( main ${Boost_LIBRARIES} )
当我从android项目中的jni文件夹的subdir运行常规cmake
命令(cmake ..
)时,没有问题,cmake找到了库。当我使用cmake来使用上面提到的项目提供的android.toolchain.cmake时,我得到了这个(我正在使用-DBoost_DEBUG选项)。

我设置所有变量指向我能找到的BOOST目录,我设置变量说Boost库应该是静态的,但它仍然找不到它们。我还能做什么?
答案 0 :(得分:5)
让我首先说让CMake找到Boost可能很困难,因为FindBoost.cmake
中的自动化会让你感到胆怯,而CMake的制造商KitWare拥有我曾经有过的任何热门项目的最差文档遇到。如果失败,您必须浏览FindBoost.cmake
的来源进行调试。
您安装交叉编译的boost的目录如下所示,假设为1.62.0
boost-arm-build/include
boost-arm-build/include/boost-1_62
boost-arm-build/lib
从Project-Build目录中调用CMake
cmake \
-DBoost_NO_SYSTEM_PATHS=TRUE \
-DBoost_ADDITIONAL_VERSIONS="1.62" \
-DCMAKE_TOOLCHAIN_FILE=../android.toolchain \
-DBOOST_ROOT="../boost-arm-build" \
../Project/
-DBoost_ADDITIONAL_VERSIONS
- CMake使用硬编码的字符串列表查找Boost,如果您的CMake比您构建的Boost版本旧,则不知道在include目录中查找的位置如此你需要传递它。虽然版本实际上是1.62.0,但是将boost包含在boost-1_62中,所以我使用1.62代替。在FindBoost.cmake
中,您会发现每个版本都会添加两次,例如" 1.62.0" " 1.62"出于这个原因。
您还应该检查您构建的库的文件名,我的示例让我们看一下system
:
libboost_system-gcc-mt-1_62.a
libboost_system-gcc-mt-1_62.so # Symbolic link to libboost_system-gcc-mt-1_62.so.1.62.0
libboost_system-gcc-mt-1_62.so.1.62.0
libboost_system-gcc-mt-d-1_62.a
libboost_system-gcc-mt-d-1_62.so # Symbolic link to libboost_system-gcc-mt-d-1_62.so.1.62.0
libboost_system-gcc-mt-d-1_62.so.1.62.0
gcc
- 编译器使用mt
- 多线程d
- debug 1_62
- 版本的提升,显然是如果您看到libboost_system.a,则意味着您无法使用--with-layout=versioned
构建提升,并且可能应该检查我的SO Answer on building boost using the NDK。如果您看到clang
而不是gcc
,那么您可以通过clang建立提升,但您可能需要使用Boost_COMPILER标志通知CMake存在clang。
-DBoost_COMPILER="-clang"
set(CMAKE_SYSTEM_NAME Android)
set(CROSS_COMPILER_DIR /opt/ndk-R13-standalone)
set(CMAKE_C_COMPILER ${CROSS_COMPILER_DIR}/bin/arm-linux-androideabi-gcc)
set(CMAKE_CXX_COMPILER ${CROSS_COMPILER_DIR}/bin/arm-linux-androideabi-g++)
set(ANDROID_NATIVE_API_LEVEL android-19)
set(ANDROID_ABI armeabi-v7a)
set(ANDROID_STL gnustl_static)
set(CMAKE_SYSROOT ${CROSS_COMPILER_DIR}/sysroot)
set(CMAKE_FIND_ROOT_PATH ${CMAKE_SYSROOT})
# search for programs in the build host directories
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
答案 1 :(得分:4)
我遇到了同样的问题。使用find_host_package(Boost COMPONENTS ..)
代替find_package(Boost COMPONENTS ..)
解决了我的问题。
(见http://code.google.com/p/android-cmake/issues/detail?id=16)
答案 2 :(得分:2)
这里有一些问题。
看起来你的boost库是在没有runtime-link=static
的情况下构建的,即它们没有静态链接到C ++标准库。如果是,他们的名字后缀应包含s
(请参阅boost docs on library naming)
另一个问题是CMake的FindBoost module
期望COMPONENTS
参数的格式为“date_time”,“thread”而不是您提供的全名。
另一个更重要的一点是,您不需要设置Boost_INCLUDE_DIR
或Boost_LIBRARY_DIR
;如果成功,这些由CMake模块设置。设置它们不应该引起任何问题,但这只是不必要的混乱。
此外,对于BOOST_ROOT
,BOOST_INCLUDEDIR
和BOOST_LIBRARYDIR
,这些通常会使用-D
选项通过命令行设置,或者按顺序设置为环境变量避免将特定于您机器的路径硬编码到CMakeLists.txt。
最后一点是您应该删除link_directories
来电。它自己的文档不鼓励使用它,因为你已经在target_link_libraries
调用中将完整路径传递给boost库,所以不需要它。
所以,最终版本应该更像:
#BOOST
set(Boost_USE_STATIC_LIBS ON)
set(USE_STATIC_BOOST ON) # Not sure if you really need this later. If not, delete.
set(Boost_USE_STATIC_RUNTIME OFF)
set(Boost_COMPILER -gcc)
find_package(Boost COMPONENTS thread date_time REQUIRED)
include_directories(${Boost_INCLUDE_DIRS})
#BOOSTEND
add_executable(main main.cpp)
target_link_libraries(main ${Boost_LIBRARIES})
你可以像这样调用CMake:
cmake . -DBOOST_ROOT=<path to root> -DBOOST_INCLUDEDIR=... -DBOOST_LIBRARYDIR=...
答案 3 :(得分:0)
我遇到了同样的问题。我使用这个存储库Boost for android构建了boost,我只获得了静态库。
我认为你真的不需要使用cmake的find_package。这就是我如何在我的CMakeList.txt中使用它
add_library(boost_system-gcc-mt-1_55 STATIC IMPORTED GLOBAL)
set_target_properties( # Specifies the target library.
boost_system-gcc-mt-1_55
# Specifies the parameter you want to define.
PROPERTIES IMPORTED_LOCATION
# Provides the path to the library you want to import.
${CMAKE_SOURCE_DIR}/src/main/jni/boost/lib/libboost_system-gcc-mt-1_55.a )
SET(Boost_LIBRARY_DIR ${Boost_LIBRARY_DIR} boost_system-gcc-mt-1_55)
# You can make this include just once
include_directories("src/main/jni/boost/include/boost-1_55")
target_link_libraries(${MyNDKSampleLibs}
${Boost_LIBRARY_DIR}
${log-lib}
我在这里唯一可以提到的是不要忘记${CMAKE_SOURCE_DIR}
函数中的cmake var set_target_properties
。
