# reflex-sdl2
This is a [reflex][2] host for [sdl2][0].
Writing and running [sdl2][0] apps requires version 2 of the awesome [SDL][1]
library.
## building
The first step is to install SDL.
### macOS
Using [homebrew](https://brew.sh/)...
brew install sdl2
### Ubuntu / Debian
The [sdl2 bindings][0] require SDL >= 2.0.4, or for special instructions
to be followed. Assuming you're on `Ubuntu >= 16.04`, you can run
apt-get install libsdl2-dev
otherwise please visit the org page above and install via their README.
### building with stack
After installing SDL, we can build with stack.
Using [stack][3] is the path of least resistance.
stack build
## examples
After building you can view an example using the built-in 2d renderer in
[app/Main.hs](https://github.com/schell/reflex-sdl2/blob/master/app/Main.hs).
To run the example do:
stack exec reflex-sdl2-exe
