Here is the cabal file in question: https://github.com/beala/twitter-markov/blob/5cbb3ee7bab7b87882110fe808ddce9582a5bded/twitter-markov.cabal

What's important is that it declares an executable called twitter-markov, and, in the same file, a library that the executable depends on. I can successfully build and install this project with a sandbox using cabal sandbox init && cabal install. When I try to run ghc-mod I get:

$ ghc-mod boot
ghc-mod: <command line>: cannot satisfy -package-id twitter-markov-0.1.0.0-inplace
    (use -v for more information)

I get the same error if I run it with cabal exec -- ghc-mod boot.

Version info:
ghc-mod: Built from master (bfa0b96)
ghc: 7.10.1 (installed from https://ghcformacosx.github.io/)
cabal: 1.22
OS X: 10.10.3

Please upgrade cabal-helper to at least 0.3.6.0 and recompile ghc-mod.

I tried installing cabal-helper 0.3.6.0 into my ghc-mod sandbox, but that triggered a ghc-mod-5.2.1.2 install and I got the following error:

Language/Haskell/GhcMod/Gap.hs:256:18:
    Not in scope: data constructor ‘ExposePackageId’
    Perhaps you meant ‘ExposePackage’ (imported from DynFlags)
cabal: Error: some packages failed to install:
ghc-mod-5.2.1.2 failed during the building phase. The exception was:
ExitFailure 1

Full output: https://gist.github.com/beala/c8303e4c4be73004b55a

Then I instead went into the ghc-mod.cabal file and set the cabal-helper dep to cabal-helper >= 0.3.6.0.

This successfully compiled, but I'm still getting the same error when I run ghc-mod boot.

This is what's currently installed in my ghc-mod sandbox:

rm -r dist/ in your project directory maybe the caches aren't playing along.

Blew away my project's dist/ and sandbox and re-ran cabal install . Still getting the same error. I can see with ghc-pkg list that the project lib is installed in the sandbox:

It is possible this has something to do with the -inplace at the end of the package id that ghc-mod is looking for? ghc-pkg list doesn't have that at the end of twitter-markov-0.1.0.0.

I'm pretty sure your installation still hasn't picked up the updated cabal-helper, the -inplace dep shouldn't be there at all.

I tried building ghc-mod from master again with a brand new local clone:

rm -rf ghc-mod
git clone git@github.com:kazu-yamamoto/ghc-mod.git
cd ghc-mod
cabal sandbox init && cabal install happy cabal-helper-0.3.6.0 .

Then I copy the binaries from dist/ into my path. And I'm still getting the same error.

I'm able to reproduce the issue with this simple repo containing one executable target and one lib: https://github.com/beala/test

git clone git@github.com:beala/test.git && cd test && cabal install

$ ghc-mod boot
ghc-mod: <command line>: cannot satisfy -package-id test-0.1.0.0-inplace
    (use -v for more information)

Is there any other info I can provide? Here is ghc-mod's debug output in my test project:

@DanielG I'm hitting the exact same -inplace issue as well, though on GHC 7.8.4. I replicated the issue with @beala 's test repo though I needed to change base to [4.7,4.9) to get it to compile.

As of earlier today, I've tried:

  • ghc-mod master (fails)
  • ghc-mod 5.2.1.2 (fails, though I don't have this version handy at the moment)
  • ghc-mod 4.1.6 (works)

Also, I'll run debug on it's own dir to verify if the correct version of cabal-helper was picked up. Let me know if/how I can lend a hand with this.

4.1.6

I can also reproduce this error on a clean Arch Linux install. Steps to reproduce, from a fresh, working install:

$ sudo pacman -Syu ghc cabal-install happy
$ cd /tmp
$ cabal update
$ cabal get -s ghc-mod
$ cd ghc-mod
$ cabal sandbox init
$ cabal install
$ cabal exec -- ghc-mod boot
ghc-mod: <command line>: cannot satisfy -package-id ghc-mod-0-inplace
    (use -v for more information)

Package versions: ghc-7.10.1-1, cabal-install-1.22.2.0-1, happy-1.19.5-1
