Is this easy for you to reproduce using the repo I posted earlier @DanielG or shall I go a step further and make a docker image?

DanielG commented Jan 3, 2016

Oh I didn't mean you have to provide more stuff to reproduce it, someone else just has to do it to make sure it's not a problem specific to your environment. Once someone can reproduce it we can consider it a bug.

Though I wouldn't say no to a docker image either ;)

Looks like Debian unstable's gcc/binutils is too new for ghc's runtime linker or something: ghc-mod: /home/dxld/.stack/snapshots/x86_64-linux/nightly-2015-12-28/7.10.3/lib/x86_64-linux-ghc-7.10.3/persistent-sqlite-2.2-2ogrkn2pVNi1QFcLfHXk9n/libHSpersistent-sqlite-2.2-2ogrkn2pVNi1QFcLfHXk9n.a: unhandled ELF relocation(RelA) type 42.

42 seems to be R_386_IRELATIVE.

Actually that docker container is sounding nice right about now :)

Have absolutely the same problem on Mac OS X, GHC-7.10.3, ghc-mod-5.4.0.0.

I'm experiencing the same bug, what should I post here to help debugging?

DanielG commented Jan 8, 2016

Well what we really need is to pin down the cause of this. Since @codygman's testcase is blowing up on my system a simpler one would be useful to have.

Another thing that would help a lot would be a comparison between the GHC options seen in ghc-mod debug and stack ghci. Unfortunetely even with --verbose stack doesn't even print that, all I can find is the line below which doesn't include anything interresting AFAICT so either some diving into Stack's source or raising an issue with them is in order:

2016-01-08 15:39:44.805274: [debug] Run process: ghc --interactive -i -odir=/home/dxld/.stack/global/.stack-work/odir -hidir=/home/dxld/.stack/global/.stack-work/odir -ghci-script=/tmp/ghci3265/ghci-script @(stack_03v8PatSPAPLwmtfdY8jsA:Stack.Exec src/Stack/Exec.hs:51:5)

Once we have a canonical set of options from stack that works with ghci we can start looking at what's actually in .stack-work/dist/*/*/setup-config and then find out why that doesn't end up coming out of ghc-mod (or why it's wrong but I think that's unlikely).

I don't have much time to work on ghc-mod currently so if anyone wants to do any of the above I'd be happy to provide more help.

Oh right that might actually be good enough since we're only interested in the package flags.

I don't know if this helps, but after I upgraded my default stack resolver to lts-4.0, I was having the same issue when working in pre-lts-4.0 projects. The problem disappears when you change the specific project's stack.yaml to match the default resolver (i.e., 4.0). Weird.

meditans commented Jan 8, 2016

@jasonzoladz that happened to me too, then I nuked both ~/.stack and the local directory .stack-work in my project (both are based on lts-4.0 now) and the error went away.

Ah I'm such a moron, I should've seen this earlier that's a classic problem. @codygman you're using a ghc-mod exectuable that's linked against ghc-7.10.2 in a stack project using 7.10.3! That can't work, you need to rebuild ghc-mod against the matching version of ghc.

You can see that in

StackProject (StackEnv {seDistDir = ".stack-work/dist/x86_64-linux/Cabal-1.22.5.0", seBinPath = ["/home/cody/.stack/snapshots/x86_64-linux/nightly-2015-12-28/7.10.3/bin","/home/cody/.stack/programs/x86_64-linux/ghc-7.10.3/bin","/home/cody/.local/bin","/usr/local/sbin","/usr/local/bin","/usr/sbin","/usr/bin","/sbin","/bin","/usr/games","/usr/local/games"], seSnapshotPkgDb = "/home/cody/.stack/snapshots/x86_64-linux/nightly-2015-12-28/7.10.3/pkgdb", seLocalPkgDb = "/home/cody/programming/haskell/bug-repros/ghc-mod-haskell-mode-bug/.stack-work/install/x86_64-linux/nightly-2015-12-28/7.10.3/pkgdb"})

where it mentions 7.10.3 whereas ghc-mod version spits out ghc-mod version 5.4.0.0 compiled by GHC 7.10.2.

I've gotten so used to non trivial problems with Stack I completely forgot about our classic failure cases ;)

That's correct, it works now. Did you ever figure out how to provide better
