#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 Ben, I created a minimal isolated test case that has the same problem: `git clone https://github.com/basvandijk/th-unknown-symbol-test` If you're using Nix a simple `nix-build` will show the problem. If you aren't using Nix you have to install `hs-opencv-binding` yourself (probably in a cabal sandbox) and build `play` manually. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9010#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
