Boostのライブラリは他のBoostのライブラリを利用して実装されていることが多いです。AsioはThreadを利用していますし、MPLはその他の色々なライブラリの実装の助けになっています。そういった関係を抜き出してみました。ただの暇つぶしで特に意味はありません。まあ、生きてるサンプルコードとして使えるかもしれません。
抽出方法
Boostのライブラリはそれぞれディレクトリに分けられているので、ディレクトリ=ライブラリとして、ディレクトリ内のすべてのファイル(.hpp)を走査してincludeしているファイルを元に依存関係を抜き出しました。結構適当です。ソース(.cpp)は見ていません。
ディレクトリ単位で見ているので、Math系のライブラリなど同じディレクトリに実装があるライブラリはひとまとめにされます。
ただし、AnyとかArrayは1ファイルだったので、そういうのは一部特別扱いしています。
一番使われているライブラリ
結果は長いので最後に載せます。
単に参照関係だけ見てもよく分からないので、他のライブラリからよく利用されるライブラリの上位10個までをリストにしてみました。
| ライブラリ | 参照されている数 |
|---|---|
| config | 84 |
| type_traits | 61 |
| mpl | 57 |
| utility | 51 |
| static_assert | 43 |
| iterator | 37 |
| preprocessor | 31 |
| ref | 22 |
| bind | 17 |
| functional | 16 |
一番がConfigなのは言うまでもなく、やはりライブラリのためのライブラリが出てくるというそりゃそうだろ、という結果に。
GraphとMath
Boost.Testを使っているライブラリがあったので見てみたら、GraphとMathはテストコードがソースに入っているみたいですね。これ別のところに移した方がいいんでは……(libs/*/test/ とか)。

単独で動くライブラリはIO State Saversくらいで、ほとんどは他のライブラリに依存しているようですね。
「このライブラリだけ使いたい」という時に、関連ファイルだけ抜き出すのは結構めんどくさそうです。
