There are Macs that cannot update to 10.7 or later, but which might still be viable as audio/video playing machines. Requiring sdl2 in ffmpeg kinda sucks because now a lot of ports that use ffmpeg that worked fine on Snow Leopard don't anymore, including pianobar. I just finally convinced the pianobar developers to add a compatibility getline function so that it can build on Snow Leopard again, and now ffmpeg's sdl2 requirement makes it not work on Snow Leopard again. If sdl2 can be built on Snow Leopard using a copy of the 10.7 SDK obtained from a later Xcode, and that sdl2 then works ok on Snow Leopard, then I'd be happy if we could come up with an official way to support that, and then we could do that on the buildbot, which would cover a lot of users' needs. _______________________________________________ macports-users mailing list macports-users@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/macports-users
