Installing helm 0.6.0

[Maik Klein]

Hello,
I have a few problems installing helm 0.6.0. I cloned it from github and tried "cabal install".

± % cabal install -v3                                                      !492

I am very new to haskell and I am not sure what is going on here.
I tried to search for the SDL2 package but I couldn't find it.

The SDL2 package is currently not on Hackage because it's still a work in progress. You need to check it out and manually install it, but you'll need my changes that haven't been merged yet.  https://github.com/z0w0/hsSDL2

Somewhat related to this - is the preferred installation method through Hackage or a github clone install?

[Zack Corr]

The preferred method is through Hackage, but due to hsSDL2 still being in development, the only way to install 0.6 (which I very much suggest using over 0.5 due to optimizations, improved portability & breaking API changes) is by checking out the source and building it manually.

Sorry for the delay in response, by the way.

the link to the github repo of hsSDL gave me a 404.. i've found it here https://github.com/Lemmih/hsSDL2

[Zack Corr]

Apologies, I deleted my fork because my changes were merged upstream ages ago. I'm thinking of changing it to use the sdl2 package on Hackage instead of the WIP official one so that I can release 0.6 soonish straight to Hackage. Apparently the WIP one will replace the current one when it is done. Looks like the current one is simply a bunch of low-level bindings.
