#12506: Compile time regression in GHC 8. -------------------------------------+------------------------------------- Reporter: deech | Owner: bgamari Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by deech): Replying to [comment:14 tdammers]:
I tried reproducing the problem with GHC 8.2.1, but unfortunately the build instructions no longer work with Cabal 2.0.x. It seems that `fltkhs` doesn't support Cabal 2.0, and [this github issue](https://github.com/deech/fltkhs/issues/38) tells me this might not get fixed anytime soon.
Is there an up-to-date way of reproducing the issue that I could use? Preferably one that doesn't involve `stack`, simply because I want to hook a custom-built GHC directly from git into the build so I can play with some things and cherry-pick selected changes, and this isn't trivial with stack.
I should have closed that issue, the [master branch](https://github.com/deech/fltkhs) and the latest [stable release](https://hackage.haskell.org/package/fltkhs) [should](https://github.com/deech/fltkhs/blob/master/Setup.hs#L47) work with Cabal 2.0.0.2 and GHC 8.2.1. I'm happy to help you through it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12506#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
