Use bcp : http://www.boost.org/doc/libs/1_52_0/tools/bcp/doc/html/index.html

 cd $BOOST_DIR bcp unordered_map /tmp/TEST

Now / tmp / TEST contains only the things needed for unordered_map , in my case 15Mb (unlike 734Mb for the full acceleration library)

You need at least headers because Boost packages are dependent on each other. You can select only the necessary header files, but it will really be a pain in the neck and will take you many hours. Algorithm:

  • Enable only boost/unordered_map .
  • So far, the preprocessor complains about a header that is not found:
    • Add this title.
    • Recompiled.

As a result, you will get only the necessary headers. But I do not see any advantages of this solution.
