Question

Windows build 18362
CLion 2019.1.2
Boost 1.67
Toolchain mingw-64

我正在尝试使用Boost在Clion中设置一个简单的项目。问题是当我包含增强头文件#include <boost/log/trivial.hpp>时，CLion无法找到头文件。

我的CMakeLists.txt：

cmake_minimum_required(VERSION 3.14)
project(BoostTest)

set(CMAKE_CXX_STANDARD 14)

add_executable(BoostTest main.cpp)

set(BOOST_ROOT "$ENV{HOMEPATH}/.local/share/boost")
set(Boost_ARCHITECTURE "-x64")
find_package(Boost REQUIRED COMPONENTS log)
message(STATUS "Boost_INCLUDE_DIR: ${Boost_INCLUDE_DIR}")
include_directories(${Boost_INCLUDE_DIR})
target_link_libraries(BoostTest ${Boost_LIBRARIES})

CMake的输出似乎表明已正确找到所有内容：

但是，CLion仍然无法在include语句中找到头文件。头文件确实存在于Boost_INCLUDE_DIR中指定的位置。我是Windows和CLion的新手，我可能缺少一些基本知识，但我看不到。有任何线索吗？

Answer 1

在命令行中完成此操作后，我得出的结论是CLion错误。如果include目录中不包含驱动器名称（即C:/），则CLion找不到头文件。

这是CMakeLists.txt，适用于CLion：

cmake_minimum_required(VERSION 3.14)
project(boost-test)

set(CMAKE_CXX_STANDARD 14)
add_executable(boost-test main.cpp)

set(Boost_USE_STATIC_LIBS   ON)
find_package(Boost REQUIRED COMPONENTS log)
if (Boost_FOUND)
    message(STATUS "Boost_INCLUDE_DIRS: ${Boost_INCLUDE_DIRS}")
    include_directories("C:${Boost_INCLUDE_DIRS}")
    target_link_libraries(boost-test ${Boost_LIBRARIES})
endif()

同一文件可从命令行使用，而没有将C:添加到include_directories中。

请注意，即使没有C:，CLion也会很好地构建和运行代码。因此，问题似乎完全在于基于include_directories()查找头文件。

Answer 2

我只是尝试从Ubuntu上进行此操作，不需要任何黑客工具即可使它工作。

find_package(Boost 1.40 COMPONENTS system filesystem program_options log REQUIRED) include_directories(${Boost_INCLUDE_DIRS})

不确定是否有帮助，但至少在某些地方可以使用。

CLion未找到Boost标头
