Hi, I had the recollection that lilypond nowadays can work with Guile 2, but when I checked right now in the docs, I saw them saying "Version 2.x of Guile is not currently supported" http://git.savannah.gnu.org/gitweb/?p=lilypond.git;a=blob;f=Documentation/included/compile.itexi;h=0abd68a9177912138f01055504f20721e4a507de;hb=HEAD#l85 Do you know the state of using lilypond with modern Guile? Does the lilypond in Guix use Guile 2? Does lilypond on Windows use Guile 2? Best wishes, Arne -- Unpolitisch sein heißt politisch sein ohne es zu merken
