(address . guix-patches@gnu.org)
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!
