原来工程在VS2008下运行，加载的是1.48版本的boost库，在VS2015中出现以下错误：
3>D:\boostlib\boost_1_46_1\boost/thread/xtime.hpp(23): error C2059:

其原因是C++与低版本的boost库不兼容，：
If you’re getting syntax errors when using Boost, you may need to compile your code with -std=c++11.
The TIME_UTC issue you might have read about is a side effect of using c++11. TIME_UTC is now defined as a macro in c++11, so you will need to either replace all instances of TIME_UTC with TIME_UTC_, or just use a newer (1.50.0+) version of Boost where this has been fixed already.
See: https://svn.boost.org/trac10/ticket/6940
将工程里面的boost版本改为1.68即可解决该问题。
