Build error: SDL confusion

[holdenlee]

Cloning and using cabal install gives the following error:

src\FRP\Helm.hs:44:18:
Could not find module `Graphics.UI.SDL'
It is a member of the hidden package `SDL-0.6.5.1@SDL_26jmephxohM5v84vz7MqXX'.
Perhaps you need to add `SDL' to the build-depends in your .cabal file.

I'm confused because I thought the new version depends on sdl2, not SDL. Nevertheless, I added SDL to build-depends and got another error:

[ 3 of 13] Compiling FRP.Helm.Engine  ( src\FRP\Helm\Engine.hs, dist\build\FRP\Helm\Engine.o )

src\FRP\Helm\Engine.hs:7:15:

src\FRP\Helm\Engine.hs:8:15:

I had this same issue. I had to do cabal install for an old version of SDL.

This should be all good now.
