#9010: TemplateHaskell leads to an "unknown symbol" error -------------------------------------+------------------------------------- Reporter: Feuerbach | Owner: Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by basvandijk): Hi rwbarton, yes a `cabal sandbox init; cabal install hs-opencv-binding/; cabal install play/` should be all that's required to build manually. I removed the dependency on `lens` like you suggested and the problem remains as expected. Note that I'm linking against `opencv-3.0.0`. It's very likely this has something to do with static vs dynamic linking. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9010#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
