Hi Mikhail, Mikhail Kirillov skribis: > * gnu/packages/music.scm: Add goattracker Thanks for the updated patch. I started looking into it, fixing an issue reported by ‘guix lint’, and cleaning up the source, leading to the following patch. However, goattracker no fails to build because of a missing ‘.bin’ file. Do you know what these ‘.bin’ (and ‘.dat’) files are, what their license is, and what can be done with them? Thanks in advance, Ludo’.
