In b30015e78db99d79cdb48c6c810e3fd49573c5cd GHC started to enforce this, since it applies different rules for finding the shared library base name for `hs-libraries` depending on whether they start with `HS` or with `C`. As far as I can tell this is only used by `rts`, specifically in its dependency on libffi. I have to say I don't understand why libffi can't simply be an `extra-libraries` dependency, something to do with library search paths perhaps? Is there any other reason for the convention that Haskell library names start with `HS`? Is this convention documented anywhere? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9625#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
