However, stack links the `c-sources` in alphabetical order, regardless of the order in the cabal file. This means I still get the linking error when I run `stack ghci` (if the file that should be linked first is alphabetically after another c-source file), and I don't know of a workaround in that case. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12152#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Can you give instructions to reproduce that don't depend on cabal (or stack)? It may be a cabal bug. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12152#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
