@GildedHonour
Have you installed sdl2_mixer, sdl2_ttf, sdl2_image and sdl2_gfx?

[GildedHonour]

@light4 they're already specified in the Cargo.toml and that error is caused by cargo build

[ironicbrew]

@GildedHonour I had this same issue, you need to install them on Arch separately to get the examples to work

ex.

https://archlinux.org/packages/extra/x86_64/sdl2_gfx/

pacman -S sdl2_gfx
