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

We have a flag to working better with cabal, you can try: stack exec --no-ghc-package-path -- cabal install I'm under the impression that there are changes planned to cabal (possibly already implemented but not released) that will allow it to function nicely with the GHC_PACKAGE_PATH environment variable, but I'm uncertain if that's true.
