I am using stack for my Haskell development and Syntastic for my error checking when editing in Vim
. I have not installed the haskell-platform
, instead, I use a stack build --install-ghc
to get my environment up and running using the supported GHC
, cabal
and lts
packages.
Normally, I use a cabal sandbox
and syntastic
works well with this. I see when I do a let g:syntastic_debug=3
in Vim
, syntastic
runs a cabal configure
which checks if the project dependencies are installed and then goes ahead and does some hlint
, hdevtools
and ghc-mod
magic to give me some warnings and/or error messages.
Now, here is my problem. Since my cabal
setup (installed from stack
) doesn't know about my dependencies installed at .stack-work
or .stack
(not sure), it complains that I am missing necessary packages and blows up when syntastic runs in my Vim
instance.
Trying to run a stack exec -- cabal configure
returns the following 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).
I haven't found out how to pass the --package-db
option with the correct database. Nothing seems to work there.
So, the quetion - will successfully running a stack exec -- cabal configure
, avoiding the GHC_PACKAGE_PATH
issue get me to a working setup? Can anyone give me some direction here?
hdevtools works. See here: http://seanhess.github.io/2015/08/05/practical-haskell-editors.html
I'm planning on keeping that up to date as new tools come out (like stack-ide).
