c++ - Boost 记录器链接问题

Question

我正在编写一个使用 Boost 库的程序。我在链接和使用程序选项方面没有任何问题，但我似乎无法让 boost 日志正常工作。谁能告诉我我错过了什么？

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 ;

这是我得到的错误:

我遇到了同样的问题，在我的情况下，问题是我只使用动态库编译了 boost，而忘记定义 BOOST_ALL_DYN_LINK .

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

作为测试，尝试编译

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

(应该加上#include <boost/log/support/date_time.hpp>，示例已损坏。)

并添加 #define BOOST_LOG_DYN_LINK

我可以用 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 编译这个例子
