Re: [Haskell-iPhone] trying to run the examples

These are two examples of running iPad apps. iPhone and iPad apps do not differ in terms of any generated machine code, but only in some xcode stuff. There is a SplitViewController that is only available on the iPad, so a direct port is not possible. I need to become more clever than I am at the moment

The GHC-iPhone PDF document has a walk-through of creating a new xcode project that includes the GHC-iPhone code. Please walk through those steps (I walked through them for both the Lisp thing and the Visi thing), but with a base iPhone xcode template rather than a base iPad xcode template and you'll get a running project. Yes, it took some time, other things on my mind. I made a simple Hello Fibonacci app. I only had problems with the Haskell binary stuff. You need to have a cabal and Main.hs file before you can compile and the given env variable is wrong. It should be: $CONFIGURATION_BUILD_DIR/dist/build/<project> Then I can compile for all targets. After a lot of strange errors I noticed that Haskell main is not the starting point but you have to adjust main.m to get things working. From your examples I saw you use the ViewController in Haskell. I omitted that. I made a C interface and that was sufficient for this simple case. It touches the interesting point of what you do in Haskell and what in Objective C. I saw there is a FFI in development for Obj C. That should make things easier I hope. If `the other things are off my mind' I'll try to add the scheme interpreter and then find some task I can't live without running it in Haskell in my iPhone

thanks, Ton

Yes. The qcon_demo tag is the demarcation of where the code properly compiled for the iPad.

Then I went and did a bunch of stuff that requires GHC 7 and also splits the language out from the iPad part because Visi will run on OS X and in the cloud as well as on the iPad.

I wonder if the app is specific iPad. I like to make an iPhone app, the screen is of course too small, but as a test it might be fine. I don't have access to an iPad.
