Hackage version of c2hs fails to build with GHC-8.8.4 or 8.10.2 about c2hs

[iko-deleted]

you should be able to do something similar with a cabal.project file

i think

source-repository-package
    type: git
    location: https://github.com/haskell/c2hs.git
    tag: 20d3c8dedde83af91c4ac06486bf346316e07285

would work?

this works perfectly fine with the version from the repo head; i assume it has already been fixed somewhere

in the meantime i got around this by adding

extra-deps:
- git: https://github.com/haskell/c2hs.git
  commit: 20d3c8dedde83af91c4ac06486bf346316e07285

to my stack.yaml

i assume there's something similar with cabal

Indeed, this solution works.

For future reference, I'm running GHC 8.8.4, cabal-install 3.2.0, Fedora 33

i getting this as well, attempting to install from stackage lts-11.3

error is slightly different:

I'm having the same issue but not directly since I'm using gi-cairo-render in a project, which fails to compile since it can't build this dependency.

Any workaround? I'm using cabal, not stack, btw.

I think it builds with 8.10.4 now (when pulled from Hackage). Thanks!
