GHC 9.4 compatibility

Open arybczak opened this issue 3 years ago • 6 comments

cleff just needs bumps of upper versions of base and template-haskell to build with 9.4.1.

Unfortunately the story for cleff-plugin seems to be more complicated due to removal of derived constraints.

It wasn't too complicated, just a few shifts in the data constructors. https://github.com/re-xyr/cleff/pull/29

Though I take it back, some extra work is needed to for the CPP pragmas.

Any luck on the plugin?

Hi. To let you know. I'm personally not aiming at fixing this issue at the moment.

Though an example of a fix can be seen here: https://github.com/polysemy-research/polysemy/commit/f9b19c022b0a5c18e473b0127172b6a3c4f94be2

cleff seems to build fine on 9.4 and 9.6. Is this issue resolved?

(Relatedly, it requires --allow-newer for 9.8)

Just a heads up that ghc-9.6 has problems with plugins in general. The link below is for polysemy, but I've had the same trouble in effectful. Surely cleff is affected too.
