如何将升压记录添加到c ++项目中？
我第一次尝试将Boost添加到我的家庭开发环境中。我现在想做的就是能够使用boost的日志记录实现来记录我当前正在打印到stdout到文件的一些错误。我开始使用lambda示例代码进行构建，现在我尝试添加日志记录示例代码，但我收到此错误：
C:\boost_1_62_0/libs/log/src/text_file_backend.cpp:597: undefined reference to `boost::filesystem::absolute(boost::filesystem::path const&, boost::filesystem::path const&)'
我的代码是：
/* for logging */
#include <boost/log/core.hpp>
#include <boost/log/trivial.hpp>
#include <boost/log/expressions.hpp>
#include <boost/log/utility/setup/file.hpp>
namespace logging = boost::log;
void init(){
logging::add_file_log("sample.log");
logging::core::get()->set_filter
(
logging::trivial::severity >= logging::trivial::info
);
}
如果我发表评论＆＃39; logging :: add_file_log（＆＃34; sample.log＆＃34;）;＆＃39;它建立得很好
