Using Boost unordered_map

I want to include boost::unordered_map in my project without downloading the whole Boost package. How can I do that?

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 required for unordered_map, in my case 15Mb (as opposed to 734Mb for the full boost library)

You need at least headers because Boost packages depend on each other. You might want to select only needed header files but it will really be pain in the neck and will take you many hours. The algorithm is:

  1. Include only boost/unordered_map.
  2. While preprocessor complains about header that is not found:
    • Add that header.
    • Recompile.

You will end up with only necessary headers. But I can't see any advantages of this solution.
