Boost-Protokoll auf OSX Verknüpfung Fehler

Question

Ich habe versucht, das folgende Beispiel-Programm aus den Boost-Tutorial zum Kompilieren eines Logger des ganzen Morgen zu erstellen und zu können, was nicht funktioniere ich falsch mache:

#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(); 
} 

mit den folgenden Befehle:

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 

Und ich bin mit einer massiven Fehlermeldung erfüllen, die wie folgt endet:

Boost wurde installiert mit:

brew install boost --c++11 

Irgendwelche Ideen, was los ist?

UPDATE

versehentlich Nachdem versucht, durch gavinb den Code in C wie erwähnt zu kompilieren, ich habe versucht, mit dem richtigen c neu kompilieren ++ Compiler:

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

ld: symbol(s) not found for architecture x86_64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

Answer 1

Diese Symbole gehören zu den C++ Laufzeit:

___cxa_throw 
___gxx_personality_v0 

Wenn der Linker beschwert, dass diese fehlen, liegt das daran, dass Sie die App als C-App und nicht als C++ - App verknüpfen.

Anstatt clang aufzurufen, verwenden Sie einfach c++ zum Kompilieren und Verknüpfen und es sollte funktionieren.

Einige Boost-Bibliotheken sind Header-only (stark templated), was bedeutet, dass die Implementierung vollständig von Headern bereitgestellt wird und somit keine separate Bibliothek verknüpft werden muss. Aber einige Boost-Bibliotheken (überprüfen Sie die Dokumentation, wie dies speziell notiert ist) erfordern für die Implementierung eine Verknüpfung .so oder .dylib. Dazu muss der Bibliotheksname mit dem Flag -l angegeben werden, z. B. -lboost_thread-mt und möglicherweise das Flag -L, wenn sich die Bibliotheken nicht in Ihrem Bibliothekspfad befinden.

In Ihrem Fall benötigen sowohl die Threading- als auch die Logging-Bibliotheken eigene Bibliotheken, die zur Verknüpfungsstufe hinzugefügt werden. Diese hängen auch von der Systembibliothek ab (einer gemeinsamen/gemeinsam genutzten Bibliothek). Wie Sie entdeckt, bedeutet dies folgendes Link Phasenaddiereinheit:

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

Answer 2

schließlich einen Befehl gefunden, die das Problem gelöst:

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