我对加速不熟悉。我想在boost中使用该类，例如boost :: context :: fiber和boost :: context :: continuation。因此，我下载了Boost 1.68的最新版本。通过官方网站上的instruction进行构建。
首先，运行引导程序并生成b2文件。
$ ./bootstrap.sh --with-libraries=all --prefix=/usr/local/boost_168_build
然后通过安装运行它。
@--:/usr/local/boost_1_68_0$ ./b2 --show-libraries
The following libraries require building:
- atomic
- chrono
- container
- context
- contract
- coroutine
- date_time
- exception
- fiber
- filesystem
- graph
- graph_parallel
- iostreams
- locale
- log
- math
- mpi
- program_options
- python
- random
- regex
- serialization
- signals
- stacktrace
- system
- test
- thread
- timer
- type_erasure
- wave
@--:/usr/local/boost_1_68_0$ sudo ./b2 install
然后我做一个cmake项目来创建一个Cmakelist。
cmake_minimum_required(VERSION 3.12)
project(boost_context)
set(Boost_USE_STATIC_LIBS OFF) # only find static libs
set(Boost_USE_MULTITHREADED ON)
set(Boost_USE_STATIC_RUNTIME OFF)
set(CMAKE_CXX_STANDARD 11)
set (BOOST_ROOT
"/usr/local/boost_1_68_0")
set (BOOST_LIBRARYDIR
"/usr/local/boost_1_68_0/lib")
find_package( Boost REQUIRED COMPONENTS context fiber)
if(Boost_FOUND)
ADD_DEFINITIONS( "-DHAS_BOOST" )
message(STATUS ${Boost_INCLUDE_DIRS})
# include_directories(${Boost_INCLUDE_DIRS})
message(STATUS ${Boost_LIBRARIES})
message(STATUS ${BOOST_LIBRARYDIR})
message(STATUS ${Boost_LIBRARIES})
message(STATUS ${Boost_LIBRARIES})
message(STATUS ${Boost_LIBRARIES})
endif()
add_executable(boost_context main.cpp)
但是当我打开Boost_USE_STATIC_LIBS时
cmake将报告：
/clion-2018.2.5/bin/cmake/linux/bin/cmake -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - Unix Makefiles"
/Other_Project/boost-context
CMake Error at /clion-2018.2.5/bin/cmake/linux/share/cmake-

关闭Boost_USE_STATIC_LIBS
cmake将报告：

最后，您知道我对为什么能找到它感到真正的困惑吗？

有人能告诉我我想念的地方吗？谢谢

您可以使用use：
b2 cxxflags="-std=c++14" --reconfigure --with-fiber
编译libboost_fiber.a

fiber是仅标头的库，因此无需链接，也无需将其添加为要查找的组件。
已编译库的列表在文档中：https://www.boost.org/doc/libs/1_68_0/more/getting_started/unix-variants.html#header-only-libraries
