Hi, these patches update sdl2 to the latest release and enable udev support. Without udev I experienced freezes every few seconds in certain games (for instance hedgewars and supertux) as SDL searched through /dev/input for joysticks. Since libudev is dlopened, I add it to rpath in make-flags. During build this overrides LDFLAGS from the base package’s configure-flags, which add mesa to rpath. AFAICT this is OK as sdl2 already includes mesa by linking libgbm. (Perhaps we could move LDFLAGS to make-flags in the base package, and make the override explicit in the derived package? Or have sdl2 find and modify the LDFLAGS entry from the base configure-flags, but that seems more trouble than it’s worth.) I was able to rebuild all dependent packages with no (new) failures. I ran several games and everything appears OK, but I don’t have a joystick or gamepad to try. There have been some issues in the past with SDL not finding (correct) libraries¹, so it would be good to test this on a foreign Guix install. As for the version bump, the changelog² doesn’t mention any significant changes except for hidapi support, which is disabled by default. Thanks!
