If your library is only dependent on boost, not any other library like nana then it will be better in most of the beginner programmers. IF your library is pre-compiled then it will catch popularity soon, because "allegro 5" is popular for two reasons :- 1. It is very powerful and vast. 2. It is very very easy to deploy, than SDL and SFML. The first choice of the beginner programmers is always SDL but they quickly move to Allegro because of the availability of pre-built binaries. -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Dev-f2600599.html
