【问题描述】：

我编译了 boost lib 并得到了这些。

//Shared/dynamic link libraries

24/03/2010  11:25 PM            17,054 boost_thread-vc80-mt-1_42.lib
24/03/2010  11:25 PM            17,054 boost_thread-vc80-mt.lib

24/03/2010  11:25 PM            73,728 boost_thread-vc80-mt-gd-1_42.dll
24/03/2010  11:25 PM            17,214 boost_thread-vc80-mt-gd-1_42.lib
24/03/2010  11:25 PM            17,214 boost_thread-vc80-mt-gd.lib

// Static libs... does not need any dlls

24/03/2010  11:25 PM           381,716 libboost_thread-vc80-mt.lib

24/03/2010  11:25 PM           999,552 libboost_thread-vc80-mt-gd-1_42.lib
24/03/2010  11:25 PM           999,552 libboost_thread-vc80-mt-gd.lib

24/03/2010  11:25 PM           421,050 libboost_thread-vc80-mt-s-1_42.lib
24/03/2010  11:25 PM           421,050 libboost_thread-vc80-mt-s.lib

24/03/2010  11:25 PM         1,015,688 libboost_thread-vc80-mt-sgd-1_42.lib
24/03/2010  11:25 PM         1,015,688 libboost_thread-vc80-mt-sgd.lib

在 Visual Studio 中，我使用 boost 线程库编写了一个测试应用程序。根据代码生成设置，它只要求这四个库（如多线程调试、多线程、多线程调试 dll 和多线程 dll）

24/03/2010  11:25 PM           381,716 libboost_thread-vc80-mt-1_42.lib
24/03/2010  11:25 PM           381,716 libboost_thread-vc80-mt.lib

24/03/2010  11:25 PM           999,552 libboost_thread-vc80-mt-gd-1_42.lib
24/03/2010  11:25 PM           999,552 libboost_thread-vc80-mt-gd.lib

24/03/2010  11:25 PM           421,050 libboost_thread-vc80-mt-s-1_42.lib
24/03/2010  11:25 PM           421,050 libboost_thread-vc80-mt-s.lib

24/03/2010  11:25 PM         1,015,688 libboost_thread-vc80-mt-sgd-1_42.lib
24/03/2010  11:25 PM         1,015,688 libboost_thread-vc80-mt-sgd.lib

现在我的问题是如何将我的应用链接到其他 2 个库，以便它使用 dll？

24/03/2010  11:25 PM            53,248 boost_thread-vc80-mt-1_42.dll
24/03/2010  11:25 PM            17,054 boost_thread-vc80-mt-1_42.lib
24/03/2010  11:25 PM            17,054 boost_thread-vc80-mt.lib

24/03/2010  11:25 PM            73,728 boost_thread-vc80-mt-gd-1_42.dll
24/03/2010  11:25 PM            17,214 boost_thread-vc80-mt-gd-1_42.lib
24/03/2010  11:25 PM            17,214 boost_thread-vc80-mt-gd.lib

问题 2. g, s 代表什么？

【参考方案1】：

您可以通过定义 BOOST_ALL_DYN_LINK 来强制 Boost 使用 DLL - 在您的 C++ 预处理器设置中或在您的 stdafx.h 预编译头文件中定义 #define，例如：

#define BOOST_ALL_DYN_LINK

【参考方案2】：

要配置 boost，请使用用户配置标头

<boost/config/user.hpp>

然后只需查找动态链接行并更改为您想要的配置

// BOOST_ALL_DYN_LINK: Forces all libraries that have separate source, 
// to be linked as DLL's rather than static libraries on Microsoft Windows 
// (this macro is used to turn on __declspec(dllimport) modifiers, so that 
// the compiler knows which symbols to look for in a DLL rather than in a 
// static library).  Note that there may be some libraries that can only 
// be statically linked (Boost.Test for example) and others which may only 
// be dynamically linked (Boost.Threads for example), in these cases this 
// macro has no effect.
// #define BOOST_ALL_DYN_LINK

【参考方案3】：

.lib 文件是静态链接的，而 .dll 文件是动态链接的。我相信这是一个 VC 项目设置。

“lib”前缀用于静态库。使用链接=静态 's' 字母是指向运行时的静态链接。使用 runtime-link=static 'd' 是调试，使用 variant=debug “g”正在使用调试运行时，我认为它包含在“调试”变体中 已经。如果不是 runtime-debugging=on 会有所帮助。
