使用仅标头的库时增强链接器错误 [英] Boost linker errors when using header-only libraries

问题描述

我将Boost 1.53.0的以下组件与C ++ 11库结合使用...

I am using the following components of Boost 1.53.0 in conjunction with C++11 libraries...

• boost :: signals2 :: scoped_connection
• boost :: signals2 :: signal
• boost :: signals2 :: connection
• boost :: math :: constants
• boost :: circular_buffer
• boost :: lexical_cast

根据此答案，我不需要链接库使用Boost的这些部分.根据此答案，signals2应该为标头-也只有.但是，我仍然收到链接器错误...

According to this answer, I do not need to link against libraries to use these parts of Boost. According to this answer, signals2 should be header-only also. However, I still receive linker errors...

Undefined symbols for architecture i386:
  "boost::system::system_category()", referenced from:
  ___cxx_global_var_init2 in Main.o
  ...
  "boost::system::generic_category()", referenced from:
  ___cxx_global_var_init in Main.o
  ___cxx_global_var_init1 in Main.o
  ...

为什么?

推荐答案

问题是虚假的

#include <boost/thread/mutex.hpp>

偶然留在文件中间.
