Did you already look in the documentation?

http://www.boost.org/doc/libs/1_66_0/libs/geometry/doc/html/geometry/reference/algorithms/union_/union__3.html

There are examples there too.

For a union, it is not possible to do 7 boxes in one call. The most 
straightforward way is to do 6 calls (first 1 and 2, then result with 3, 
then result with 4, etc)

A makefile is not provided and not necessary, the library is header-only.
