Question

我一直在尝试将boost.Log集成到我的项目中，但在构建时我收到错误消息：

$.each(obj, function (i, data) {
   jsonData.push({ A: data.countAgree, B: data.countSomewhatAgree, C: data.countDisagree, Q: 'Question' + (i + 1) });
});

我已经检查确保我没有在任何地方定义BOOST_NO_EXCEPTIONS，但我仍然难以理解为什么我收到此错误。我的CMAKE文件如下：

/usr/lib/cross/boost/lib/libboost_date_time.so: undefined reference to `boost::throw_exception(std::exception const&)'

来自FIND的库的输出似乎没问题：

set(Boost_INCLUDE_DIR /usr/lib/cross/boost/include)
set(Boost_LIBRARY_DIR /usr/lib/cross/boost/lib)
find_package(Boost 1.63.0 COMPONENTS system filesystem log REQUIRED)

message(status "** Boost Include: ${Boost_INCLUDE_DIR}")
message(status "** Boost Libraries: ${Boost_LIBRARY_DIRS}")
message(status "** Boost Libraries: ${Boost_LIBRARIES}")

set (PROJECT_LINK_LIBS thrift crypto ssl sqlcipher)

link_directories( $ENV{LD_LIBRARY_PATH}
                ${Boost_LIBRARY_DIRS}
)

include_directories( $ENV{LD_INCLUDE_PATH}
$ENV{LD_INCLUDE_PATH}/sqlcipher
${Boost_INCLUDE_DIR}
)

add_executable(databaseManager ${MY_SRC})

target_link_libraries(databaseManager ${Boost_LIBRARIES} ${PROJECT_LINK_LIBS} )

最后，它失败的链接步骤的详细输出：

有没有人知道我还可以检查或做些什么来克服这个错误？

干杯！

*******编辑*********

有一些关于在COMPONENTS列表中添加异常的建议。我已经尝试并测试了这个，但遗憾的是收到了同样的错误。

唯一需要注意的是所有主库都是动态链接的（.so版本被拉入），而boost_exception是静态拉（.a版本）。

find_package命令的新版本：

以上更改构建错误：

find_package(Boost 1.63.0 COMPONENTS system atomic filesystem log exception REQUIRED)

如果有其他人遇到过此更新。

我能够让它发挥作用的唯一方法是使用以下代码片段：

#define BOOST_NO_EXCEPTIONS
#include <boost/throw_exception.hpp>
void boost::throw_exception(std::exception const & e){
//do nothing
}

我玩了库的顺序，明确地包括它们，使用findBoost.cmake并且一切都无济于事。我猜是一个随意的怪癖！

C ++ CMake构建错误：对`boost :: throw_exception（std :: exception const＆amp;）的未定义引用
