我已经建立了Boost 1.68(使用 https://gist.github.com/sim642/29caef3cc8afaa273ce6 ,并添加 link=static,shared 到b2命令行,也可以构建共享库。)

库似乎构建正确,我已经设置了 BOOST_INCLUDEDIR 和 BOOST_LIBRARYDIR 环境变量正确。

但是,当我将以下内容添加到 CMakeLists.txt :

find_package(Boost REQUIRED COMPONENTS system context coroutine thread random REQUIRED)

和生成 MinGW Makefiles

CMake Error at C:/Users/pbelanger/AppData/Local/JetBrains/Toolbox/apps/CLion/ch-0/182.4129.15/bin/cmake/win/share/cmake-3.12/Modules/FindBoost.cmake:2044 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.68.0

  Boost include path: C:/boost/install/include/boost-1_68

  Could not find the following static Boost libraries:

          boost_system
          boost_context
          boost_coroutine
          boost_thread
          boost_random

  Some (but not all) of the required Boost libraries were found.  You may
  need to install these additional Boost libraries.  Alternatively, set
  BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT
  to the location of Boost.

set(Boost_DEBUG ON) find_package https://pastebin.com/yRd5DPt4

c:\boost\install\lib system libboost_system-mgw81-mt-x64-1_68.dll boost_system-mgw81-mt-1_68 find_library -x64

经过数小时的研究,保罗贝朗格给出的答案挽救了我的一天。

在代码库中进一步挖掘,他们添加了一个新的选项来精确管理这个案例,因此使用最新版本的cmake,您可以添加以下选项:

set (Boost_ARCHITECTURE "-x64")

看看 FindBoost.cmake , line 1478 , 脚本将查看 CMAKE_CXX_COMPILER_ARCHITECTURE_ID 整齐构建正确的体系结构标记。但是,在我的编译器(mingw-w64 8.1)上 64位),此字符串为空。因此,架构标记被省略。

我必须手动设置这个变量的值,方法是在我之前 find_package 线:

if(WIN32 AND "x${CMAKE_CXX_COMPILER_ARCHITECTURE_ID}" STREQUAL "x")
    message(WARNING "WIN32 compiler does not specify CMAKE_CXX_COMPILER_ARCHITECTURE_ID -- filling in manually")
    if(CMAKE_SIZEOF_VOID_P EQUAL 8)
        set(CMAKE_CXX_COMPILER_ARCHITECTURE_ID "x64")
    else()
        set(CMAKE_CXX_COMPILER_ARCHITECTURE_ID "x86")
    endif()
    message(STATUS "Compiler architecture: ${CMAKE_CXX_COMPILER_ARCHITECTURE_ID}")
endif()

# now we should be able to find boost correctly. 
find_package(Boost REQUIRED COMPONENTS system context coroutine thread random REQUIRED)

这使得find_包工作正常。
