Haskell: ghc package environment

Hi in my package toaster, i cabal v2-install lib:toaster --package-env ~/myenv/

In the ~/myenv/ dir, there is .ghc.environment.x86_64-linux-9.2.2

I've also set the environment variable to point to the myenv dir.

Unfortunately, cabal install doesn't update the environment.

Am i doing the wrong way?

when I runghc Hello.hs, it says that toaster is hidden.

Found the answer:

cabal install --lib lib:toaster --overwrite-policy=always --env ~/dev/haskell/pkg_env/

By default, cabal install only installs executables, storing libraries built along the way only in its cache. If you want the library to be put somewhere, you must add --lib to your cabal install line.
