Hi Ludo, Thanks for looking into this! > It misses the very first line. :-) Oops :-) > Two things: output names are lowercase by convention, and the > (unofficial) convention for the GUI output is “gui”. OK. The three outputs are now "out", "gui" and "opengl". > Does it make sense to separate the two GUI outputs?

A good reason for separating them is output size (with dependencies): out: 72.7 MiB gui: 82.1 MiB opengl: 416.8 MiB For software aiming at minimalism, that looks important enough to me. In particular when using "guix pack" to deploy on small machines. > Rather #:tests? #f with a comment explaining why. OK. > Could you send one last revision? Coming... Cheers, Konrad.
