hdevtools still does not play nice with stack #78
Description
Hi. I'm trying to use hdevtools on stack project with lts-9.1. Unfortunately, I can't install it with stack build, as it gives me this error:
• Couldn't match type ‘[email protected]:GHC.PackageDb.ExposedModule
GHC.UnitId GHC.ModuleName’
with ‘GHC.PackageDb.ExposedModule unitid0 GHC.ModuleName’
NB: ‘GHC.PackageDb.ExposedModule’
is defined in ‘GHC.PackageDb’
in package ‘[email protected]’
‘[email protected]:GHC.PackageDb.ExposedModule’
is defined in ‘GHC.PackageDb’
in package ‘[email protected]’
Expected type: [GHC.PackageDb.ExposedModule unitid0 GHC.ModuleName]
Actual type: [[email protected]:GHC.PackageDb.ExposedModule
GHC.UnitId GHC.ModuleName]
• In the second argument of ‘map’, namely
‘(concatMap exposedModules pkgConfigs)’
In the second argument of ‘($)’, namely
‘map exposedName (concatMap exposedModules pkgConfigs)’
In a stmt of a 'do' block:
return $ map exposedName (concatMap exposedModules pkgConfigs)
And a bunch of warning about package versons as well:
Warning: This package indirectly depends on multiple versions of the same
package. This is highly likely to cause a compile failure.

I tried two different configurations:
- Use system-wide
hdevtools(I'm on Gentoo with ghc-8.0.2) with mystackproject. When I try this, I get an error:
Cabal file: Just "/home/maks/Projects/***/***.cabal"
Stack file: Just "/home/maks/Projects/***/stack.yaml"
Socket file: "/home/maks/Projects/***/.hdevtools.sock"
can't load .so/.DLL for: /home/maks/IDE/stack/programs/x86_64-linux/ghc-tinfo6-nopie-8.0.2/lib/ghc-8.0.2/bytestring-0.10.8.1/libHSbytestring-0.10.8.1-ghc8.0.2.so (/home/maks/IDE/stack/programs/x86_64-linux/ghc-tinfo6-nopie-8.0.2/lib/ghc-8.0.2/bytestring-0.10.8.1/libHSbytestring-0.10.8.1-ghc8.0.2.so: undefined symbol: base_GHCziIOziHandleziInternals_ioezuEOF2_closure)
- Build latest hdevtools from this repo with stack hackery (basically, I got configure command from
stack build -vand changed--dependency=ghc-boot=...pointing toghc-bootinside.stack-workto point to one in~/.stack/...). This way I could buildhdevtoolsand run it withstack exec, but I get another error when I try to check a file:
Cabal file: Just "/home/maks/Projects/***/***.cabal"
Stack file: Just "/home/maks/Projects/***/stack.yaml"
Socket file: "/home/maks/Projects/***/.hdevtools.sock"
Cabal error: Use of GHC's environment variable GHC_PACKAGE_PATH is incompatible with Cabal. Use the flag --package-db to specify a package database (it can be used multiple times).
Can something be done about it? I'd actually prefer if system-wide hdevtools (from portage) could work any stack-based project.
