1 Opéra Libre is not a software, though it is
2 developed and licensed like one. Opéra libre is
3 just... an opera; a music score that is meant to be
4 printed, read, played and sung.
7 To compile the source code and obtain the score as
8 a printable or playble file, you will have to use the
9 LilyPond music typesetting engine. It is a GNU Free
10 software that is both powerful and simple to learn,
11 and that you can download on http://www.lilypond.org.
12 It runs on most modern Operating Systems, and has been
13 ported for various architectures.
16 Having installed LilyPond, just compile the main
17 source file, either vocal_score.ly for the Vocal
18 Score, full_score.ly for the Full score or
19 livret_score.ly for the libretto (these options are
20 not fully implemented yet).
