[Haskell-cafe] How to direct cabal to use an alternative ghc version, ala stack?

[David Banas]

Hi all,

How do I direct cabal to use an alternative (i.e. - not my system’s default) version of ghc, which I’ve installed, via stack?

I tried this:

stack exec cabal install ...

but got this:

cabal: 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).

Thanks,
-db
