@DanielG the alternative is littering GHC code with equivalent to ghcjs code using undefined and pragma. switching binary once is a very mild operation in comparison

yeah, that's nothing given the upshot. just switch the binary by hand once. it'd be nice to have https://github.com/DanielG/ghc-mod/issues/615, but one can do without and is a separate issue

where does ghc-mod find its library ? If launched with command line, from the location of `ghc-mod debug`, say `GHC System libraries: /Users/nrolland/.nix-profile/lib/ghc-7.10.2` from `stack exec -- ghc-mod boot` this...

as for me, somehow my emacs config was generating a "dist" directory automatically... leading to the known issue with stack

I have the same here with message ``` ghc-mod -v7 --ghcOpt=v7 boot not sandboxed DEBUG: reading cache: /Users/nrolland/Sync/clones/cqrs/cqrs-example/.stack-work/dist/x86_64-osx/Cabal-1.22.5.0/setup-config.ghc-mod.package-options ghc-mod: : cannot satisfy -package-id aeson-0.8.1.1-8e47ef90edf199d539b7274d4f606480: aeson-0.8.1.1-8e47ef90edf199d539b7274d4f606480 is unusable due to missing...

same after nuking .stack-work ``` $ ghc-mod -v7 --ghcOpt=v7 boot not sandboxed DEBUG: regenerating cache: /Users/nrolland/Sync/clones/cqrs/cqrs-example/.stack-work/dist/x86_64-osx/Cabal-1.22.5.0/setup-config.ghc-mod.package-options (cache missing or unreadable) DEBUG: writing memory cache: /Users/nrolland/Sync/clones/cqrs/cqrs-example/.stack-work/dist/x86_64-osx/Cabal-1.22.5.0/setup-config.ghc-mod.package-options ghc-mod: : cannot satisfy -package-id...

I think my issue is linked to ghc-7.10.3, going from nightly-2015-12-16 (7.10.3) to nightly-2015-12-13 (7.10.2) fixed it.
