Error while buillding with stack - Could not find module ‘GI.GModule.Structs.Module’

[sigrdrifa]

I wanted to try out gi-gtk-declarative so I created an empty stack project and added gi-gtk-declarative and gi-gtk-declarative-app-simple as dependencies (using the latest lts resolver 17.10) but unfortunately it fails to build stating that the gdk pixbuf module cannot build:

has anyone else had this issue and are there any workarounds?

[Matthew-Mosior]

I'm running into the same issue.

[owickstrom]

Seems to be same as https://github.com/haskell-gi/haskell-gi/issues/339? And that thread has some workarounds.

I could resolve this by following this comment in haskell-gi/haskell-gi#339 as @owickstrom said.

Here's my commit that uses it. But even though it's working for now, I'm not sure whether it works fine for all cases because:

• It requires to update lts from 17.0 to 17.9
• snapshot file is placed unconsciously
• It ignores some bound constraints in cabal file. (e.g. it forces to use haskell-gi-0.25.0 whereas cabal file restrict it to be 0.24.*)
