подталкивания журнал связывая ошибку на OSX

Question

Я пытаюсь скомпилировать следующий пример программу из повышающего учебника, чтобы создать регистратор все утро и не могу работать, что я делаю неправильно:

#include <boost/log/common.hpp> 
#include <boost/log/sinks.hpp> 
#include <boost/log/sources/severity_logger.hpp> 
#include <boost/log/expressions.hpp> 
#include <boost/core/null_deleter.hpp> 
#include <boost/shared_ptr.hpp> 
#include <iostream> 

using namespace boost::log; 

BOOST_LOG_ATTRIBUTE_KEYWORD(severity, "Severity", int) 

int main() 
{ 
    typedef sinks::asynchronous_sink<sinks::text_ostream_backend> text_sink; 
    boost::shared_ptr<text_sink> sink = boost::make_shared<text_sink>(); 

    boost::shared_ptr<std::ostream> stream{&std::clog, 
    boost::null_deleter{}}; 
    sink->locked_backend()->add_stream(stream); 
    sink->set_filter(severity > 0); 
    sink->set_formatter(expressions::stream << severity << ": " << 
    expressions::smessage); 

    core::get()->add_sink(sink); 

    sources::severity_logger<int> lg; 

    BOOST_LOG_SEV(lg, 0) << "note"; 
    BOOST_LOG_SEV(lg, 1) << "warning"; 
    BOOST_LOG_SEV(lg, 2) << "error"; 
    sink->flush(); 
} 

используя следующие команды:

clang -std=c++11 -c ./test.cpp -Wall -DBOOST_ALL_NO_LIB -DBOOST_ALL_DYN_LINK -DBOOST_LOG_DYN_LINK 
clang test.o -o test -DBOOST_ALL_NO_LIB -DBOOST_ALL_DYN_LINK -DBOOST_LOG_DYN_LINK 

И я встретился с массивным сообщением об ошибке, которое заканчивается так:

Boost был установлен с использованием:

brew install boost --c++11 

Любые идеи, что происходит?

UPDATE

После случайно попытался скомпилировать код в C, как указывал gavinb, я попытался перекомпилировать с правильным C++ компилятор:

c++ -std=c++11 -c ./test.cpp -Wall -DBOOST_ALL_NO_LIB -DBOOST_ALL_DYN_LINK -DBOOST_LOG_DYN_LINK 
c++ test.o -o test -DBOOST_ALL_NO_LIB -DBOOST_ALL_DYN_LINK -DBOOST_LOG_DYN_LINK

clang: error: linker command failed with exit code 1 (use -v to see invocation) 

Answer 1

Эти символы принадлежат выполнения в C++:

___cxa_throw 
___gxx_personality_v0 

Когда компоновщик жалуется, что это отсутствует, это связано с тем, что вы связываете приложение как приложение C, а не с C++-приложением.

Вместо того, чтобы ссылаться на clang, просто используйте c++ для компиляции и связывания, и он должен работать.

Некоторые библиотеки Boost предназначены только для заголовков (они сильно затенены), что означает, что реализация полностью обеспечивается заголовками и, следовательно, не требует связывания отдельной библиотеки. Но некоторые библиотеки Boost (проверьте документацию, так как это специально указано) требуют связывания .so или .dylib для реализации. Для этого требуется указать имя библиотеки с флагом -l, например -lboost_thread-mt и, возможно, флаг -L, если библиотеки не находятся на пути к вашей библиотеке.

В вашем случае библиотекам потоков и журналов необходимы собственные библиотеки, добавленные на этап ссылки, и это также зависит от системной библиотеки (общей/общей библиотеки). Как вы обнаружили, это означает, добавив следующую строку в фазе ссылка:

-lpthread -lboost_log-mt -lboost_thread-mt -lboost_system-mt 

Answer 2

Наконец нашел команду, что решить проблему:

clang++ -std=c++11 -DBOOST_LOG_DYN_LINK ./test.cpp -o test -lboost_log-mt -lpthread -lboost_thread-mt -lboost_system-mt
