I am in the process of tidying up a solution for this. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7723 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

I re-tested the existing Itimer.c and it doesn't work (it doesn't fire). So I've added a patch here to give a pthread-based implementation that does work on iOS. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7723#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

If you don't use the Xcode debugger, then you don't get any console output. In this iteration of the project I have only tested with the debugger (because otherwise I'd need to do a graphical or network program to test if ITimer works). I am trying to avoid doing work, so here's a proposal: If you accept this vague explanation for now, I'll promise to refine this later once I have real iOS programs running. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7723#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
