最近有一个VS2010的工程用到了boost库，编译的时候报下面的错误：
>LINK : fatal error LNK1104: cannot open file 'libboost_thread-vc100-mt-s-1_52.lib'
到boost库目录： ~boost_1_52_0stagelib 下一看，果然没有这个库，只有 libboost_thread-vc100-mt-gd-1_52.lib 与 libboost_thread-vc100-mt-1_52.lib。
那这个 'libboost_thread-vc100-mt-s-1_52.lib' 跟libboost_thread-vc100-mt-1_52.lib 有何差别呢？
-s
ABI tag: encodes details that affect the library's interoperability with other compiled code. For each such feature, a single letter is added to the tag:
Key Use this library when: Boost.Build option s linking statically to the C++ standard library and compiler runtime support libraries. runtime-link=static g using debug versions of the standard and runtime support libraries. runtime-debugging=on y using a special debug build of Python. python-debugging=on d building a debug version of your code.7 variant=debug p using the STLPort standard library rather than the default one supplied with your compiler. stdlib=stlport
For example, if you build a debug version of your code for use with debug versions of the static runtime library and the STLPort standard library in “native iostreams” mode, the tag would be:-sgdpn. If none of the above apply, the ABI tag is ommitted.
原来，-s 代表 “runtime-link-static"，我的工程是用这种方式使用boost库的，因此需要'libboost_thread-vc100-mt-s-1_52.lib'
于是重新编译boost库，用下面的编译命令：
b2 --build-dir=c:oost-build --build-type=complete msvc stage link=static
