boost库的编译的Properties:属性

  variant=debug|release            Select the build variant

  link=static|shared                    Whether to build static or shared libraries

  threading=single|multi            Whether to build single or multithreaded binaries

  runtime-link=static|shared      Whether to link to static or shared C and C++ runtime.

即使添加了  threading=mulit 还是无法生成  libboost_thread-mt.a ， 只会生成  libboost_thread.a

那只有用 complete 来生成了

./bjam --build-type=complete --layout=tagged
