#8865: Cannot derive well-kinded instance of form ‘Category ----------------------------------------------+---------------------------- Reporter: adinapoli | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: Resolution: | 7.8.1-rc2 Operating System: MacOS X | Keywords: Type of failure: GHC rejects valid program | Architecture: x86_64 Test Case: | (amd64) Blocking: | Difficulty: Unknown | Blocked By: | Related Tickets: ----------------------------------------------+---------------------------- Comment (by simonpj): I'd like to reproduce this, but need definition for `StaticArrowT`, `KnownArgs` etc. Can you add those definitions to the module, and give the complete source code for a module that shows the problem? Ideally, not depending on other libraries. Thanks Simon -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8865#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
