IIUC, you're looking to define a `stack.yaml` file which will set up all of the packages and settings, and then have a script you run to tell Stack to build the appropriate packages. That sounds fine; I think the pieces you're missing are:
* In order to say "I have no local packages," include the line `packages: []` in your `stack.yaml` * You can use the `flags` section in your `stack.yaml` to override default cabal flags, see https://docs.haskellstack.org/en/stable/yaml_configuration/#flags On Mon, Feb 12, 2018 at 6:14 AM, Brent Yorgey <byor...@gmail.com> wrote: > Hi all, > > I have a specific goal and I'm hoping you can help me figure out the best > way to accomplish it using stack (or perhaps even using other tools if they > make more sense).
