Fix concurrent-output related TODO in the cabal.project file #1818

Closed erikd closed 3 months ago

erikd commented 3 months ago

The cabal.project file currently has:

-- concurrent-output is incompatible with our haskell.nix version due to
-- arch(wasm32).
-- TODO[sgillespie]: Upgrade haskell.nix
constraints:
  , concurrent-output < 1.10.19

Trying to build db-sync with ghc-9.10 results in a failure in the dependency solver:

> cabal build all
Resolving dependencies...
Error: cabal: Could not resolve dependencies:

concurrent-output-1.10.19 (constraint from project config

That will need to be fixed before ghc-9.10 can be supported.
