Re: [Haskell-cafe] Passing a cabal flag to stack

Hi!

So whats the official way of putting the -fgtk3 flag into stack?

To pass that flag to poppler, the syntax is --flag poppler:gtk3

1. Delete every file/directory under .stack-work that has the word poppler

That shouldn't be necessary.

2. stack build poppler --flag gtk:gtk3 3. stack build

It's best to be consistent about flag settings. It might be easiest to put them in your stack.yaml: http://docs.haskellstack.org/en/stable/yaml_configuration/#flags Hope that helps! Simon
