Устранение проблемы с буфером журнала

Я пишу программу, которая использует библиотеки Boost. У меня не было проблем с связыванием и использованием опций программы, но я не могу заставить журнал бухгалтерии работать правильно. Может ли кто-нибудь сказать мне, что мне не хватает?

jamroot.jam

using clang : : : <compileflags>-Isrc/main/headers <compileflags>-std=c++11 <compileflags>-stdlib=libc++ <linkflags>-std=c++11 <linkflags>-stdlib=libc++ ;
lib boost_program_options boost_log ;
exe foghorn : [ glob src/main/cpp/*.cpp ] boost_program_options boost_log ;

Это ошибка, которую я получаю:

У меня была такая же проблема, и в моем случае проблема заключалась в том, что я только что скомпилировал только с динамическими libs и забыл определить BOOST_ALL_DYN_LINK.

http://www.boost.org/doc/libs/1_54_0/libs/log/doc/html/log/rationale/namespace_mangling.html

В качестве теста попытайтесь скомпилировать

http://www.boost.org/doc/libs/1_54_0/libs/log/example/doc/tutorial_fmt_stream.cpp

(#include <boost/log/support/date_time.hpp> следует добавить, пример разбит.)

а также добавить #define BOOST_LOG_DYN_LINK

Я мог бы скомпилировать пример с помощью g++ tutorial_fmt_stream.cpp -Wall -L$BOOST/lib/ -I $BOOST/include/ -pthread -lboost_system -lboost_log_setup -lboost_log -lboost_date_time -lboost_thread -lrt -lboost_filesystem

Ответ 2

Если вы используете cmake для управления повышением, просто не забывайте иметь что-то вроде:

add_definitions(-DBOOST_LOG_DYN_LINK)

в CMakeLists.txt

Ответ 3

У меня была та же проблема, которая была сложным способом увязки. В сообщении показано, что пытается связать со статическими библиотеками (.... v2s...), но компоновщик предоставляет только динамические библиотеки (потому что это глупо).

Ваша сборка Boost может генерировать файлы .so и .a, а gcc запутывается, когда они присутствуют.

У меня была библиотека, построенная с помощью CMake, которая использует статические библиотеки Boost. Если вы связываете эту библиотеку с программой, использующей поток Makefile, программа также должна указать те же самые статические библиотеки Boost. Однако параметр -l для компоновщика нечеткий, а не ваш друг здесь. Если вы создали Boost для статических (.a) и динамических (.so) выходов, тогда компоновщик сначала выберет динамические (.so) файлы, если вы просто используете опцию -l.

Обходной путь состоит в том, чтобы не использовать параметры -l и -l для поиска статических библиотек Boost (поскольку это не удастся), но для указания полных путей к библиотекам Boost. Например,

gcc .... -L/opt/boost_1.55/lib -lboost_log

измените на

gcc .... /opt/boost_1.55/lib/libboost_log.a

Другой вариант - указать слово -static в gcc, но для этого требуется, чтобы все библиотеки были статическими, что, вероятно, не будет работать, если вы используете что-либо помимо boost (скажем, в библиотеке librt.so).

Ответ 4

Если вы используете

void boost::log::v2s_mt_posix::init_from_stream<char>(std::basic_istream<char, std::char_traits<char> >&)

вам нужно связать

libboost_log_setup.a
