[英]Using Boost.asio with cmake?
I want to static link boost.asio to my small project without external libs (having only single exe/bin file in result to distribute it). 我想静态链接boost.asio到我没有外部库的小项目(在结果中只有单个exe / bin文件来分发它)。 Boost.asio requires Boost.system and i start to drown trying to figure out how to compile this all.
Boost.asio需要Boost.system,我开始淹死试图弄清楚如何编译这一切。 How to use Boost.asio with cmake?
如何在cmake中使用Boost.asio?
If I understand the actual question, it is fundamentally asking how to statically link against 3rd party libraries in CMake. 如果我理解实际的问题,它从根本上询问如何在CMake中静态链接第三方库。
In my environment, I have installed Boost to /opt/boost
. 在我的环境中,我已经将Boost安装到
/opt/boost
。
The easiest way is to use FindBoost.cmake
provided in a CMake installation: 最简单的方法是使用CMake安装中提供的
FindBoost.cmake
:
set(BOOST_ROOT /opt/boost)
set(Boost_USE_STATIC_LIBS ON)
find_package(Boost COMPONENTS system)
include_directories(${Boost_INCLUDE_DIR})
add_executable(example example.cpp)
target_link_libraries(example ${Boost_LIBRARIES})
A variant that finds all Boost libraries and explicitly links against the system library: 查找所有Boost库并显式链接系统库的变体:
set(BOOST_ROOT /opt/boost)
set(Boost_USE_STATIC_LIBS ON)
find_package(Boost REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
add_executable(example example.cpp)
target_link_libraries(example ${Boost_SYSTEM_LIBRARY})
If you do not have a proper Boost installation, then there are two approaches to statically link against the libraries. 如果没有正确的Boost安装,则有两种静态链接库的方法。 The first approach creates an imported CMake target:
第一种方法创建导入的CMake目标:
add_library(boost_system STATIC IMPORTED)
set_property(TARGET boost_system PROPERTY
IMPORTED_LOCATION /opt/boost/lib/libboost_system.a
)
include_directories(/opt/boost/include)
add_executable(example example.cpp)
target_link_libraries(example boost_system)
And the alternative is to explicitly list the library in target_link_libraries
rather than the target: 另一种方法是在
target_link_libraries
而不是目标中明确列出库:
include_directories(/opt/boost/include)
add_executable(example example.cpp)
target_link_libraries(example /opt/boost/lib/libboost_system.a)
