Re: Feature development

Oh, sure it is gcc ticket right now. Thanks. So this is that I’ve done so far. https://phabricator.haskell.org/D2084 https://phabricator.haskell.org/D2084 Just for your convenience I've copied my initial message: I am working on ticket https://ghc.haskell.org/trac/ghc/ticket/5850 now. I’ve come upon converting the type, which GHC.compileExpr returns, to my prompt function type [PModule] -> Int -> IO String. But this function returns ghc-prim-0.5.0.0:GHC.Prim.Any. I don’t see a clear way to convert it. So my questions are: - What this type is about? I know Any type in Haskell. Is it a specific version of it? - Or maybe it is not the best way to check a function correctness? I’ve checked out InteractiveEval module and it seems that there are only four quite similar functions to compile Expressions. Last person, who was trying to solve this problem, used Unsafe.Coerce and it is also doing this job pretty well now, but the name speaks for itself.

Seems like this issue - https://ghc.haskell.org/trac/ghc/ticket/11155

I also build on OS X and haven't had any problems recently fwiw.

Thanks for your reply, Matthew.

I’ve tried to merge my local repository with ghc/master branch and after this I couldn't build it (even checked out to a successful commit). I am getting this kind of error.

Undefined symbols for architecture x86_64: "_stg_sel_17_upd_info", referenced from: _s1yAM_info in UI.dyn_o _s1yC7_info in UI.dyn_o _s1yKD_info in UI.dyn_o _s1yLa_info in UI.dyn_o

It seems like something specific to OS X. Can you help me?

Hello Nikita,

I don't know the answers to your questions but I do know that it's easier to give help if there is some code to look at. I would suggest you put a diff up on phab with what you have done so far so that it is easy for others to give specific comments about where you are stuck.

Matt
