Question

我使用rubenvb的CLang版本在Windows上编译了Boost 1.51.0。我实际上使用MinGW编译了b2：

bootstrap mingw
... compiling b2 using mingw...

然后我用CLang编译库：

b2 toolset=clang stage --stagedir=. --build-type=complete --with-regex ...

顺便说一句，即使我指定--build-type=complete lib目录中没有DLL，但我在某处读到了CLang在Windows上仍然存在链接问题，这可能就是原因所在。无论如何静态库对我来说都没问题。我在%BOOST_ROOT%\lib：

中收到了这些文件

libboost_regex-clang31-1_51.lib
libboost_regex-clang31-d-1_51.lib
libboost_regex-clang31-mt-1_51.lib
libboost_regex-clang31-mt-d-1_51.lib
libboost_regex-clang31-mt-s-1_51.lib
libboost_regex-clang31-mt-sd-1_51.lib
libboost_regex-clang31-s-1_51.lib
libboost_regex-clang31-sd-1_51.lib

现在，如果我从命令行编译CLang的东西一切正常。问题显示当我尝试让CMake找到Boost库时：它根本找不到它们。我试过这个CMakeFiles.txt：

cmake_minimum_required (VERSION 2.8)
project(ccc)

# Setting/unsetting this does not change anything.
set(Boost_USE_STATIC_LIBS ON)

find_package(Boost COMPONENTS regex REQUIRED)

include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIRS})

add_executable(ccc main.cpp)

target_link_libraries(ccc
    ${Boost_REGEX_LIBRARY}
    )

使用MinGW（和Boost的MinGW编译版本）构建它可以工作。如果我尝试使用CLang（在设置CC=clang，CXX=clang++和BOOST_ROOT=C:/misc/boost/clang-1_51_0之后），则不会：

D:\Desktop\ppp>cmake -G "MinGW Makefiles" ..\ccc

CMake Error at C:/misc/cmake/share/cmake-2.8/Modules/FindBoost.cmake:1191 (message):
  Unable to find the requested Boost libraries.

  Boost version: 1.51.0

  Boost include path: C:/misc/boost/clang-1_51_0

  The following Boost libraries could not be found:

          boost_regex

  No Boost libraries were found.  You may need to set BOOST_LIBRARYDIR to the
  directory containing Boost libraries or BOOST_ROOT to the location of
  Boost.

  CMakeLists.txt:5 (find_package)


CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
Boost_REGEX_LIBRARY (ADVANCED)
    linked by target "ccc" in directory D:/Desktop/ccc

-- Configuring incomplete, errors occurred!

但是，如果我手动编译它再次起作用：

clang++ main.cpp -I%BOOST_ROOT% -L%BOOST_ROOT%\lib -llibboost_regex-clang31-1_51
...Ok, and the executable works

手动设置BOOST_LIBRARYDIR也不起作用。也没有使用反斜杠\。

查看文件“C：/misc/cmake/share/cmake-2.8/Modules/FindBoost.cmake”，您可以找到与您可以使用的Boost相关的所有变量的列表。您需要的是Boost_COMPILER（Boost_DETAILED_FAILURE_MSG也可用于诊断问题）：

#   Boost_COMPILER               Set this to the compiler suffix used by Boost
#                                (e.g. "-gcc43") if FindBoost has problems finding
#                                the proper Boost installation

找到使用CMake与CLang编译的Boost
