Re: [Haskell-cafe] Cross-compiling fails for package 'directory'

Is the failure of hsc2hs to support this directive just a matter of "not implemented right now", maybe by lack of importance? Or is there a fundamental problem?

See also: https://ghc.haskell.org/trac/ghc/ticket/9689 One would probably have to implement a C string literal parser to do this properly.

If fixing hsc2hs is hard, could the 'directory' package perhaps choose another way to implement this function?

Can you try this workaround? diff --git a/System/Directory/Internal.hsc b/System/Directory/Internal.hsc index a0a71db..0f9b71f 100644 --- a/System/Directory/Internal.hsc +++ b/System/Directory/Internal.hsc @@ -1,3 +1,5 @@ +{-# LANGUAGE CPP #-} +##include #include module System.Directory.Internal @@ -28,4 +30,4 @@ import System.Directory.Internal.Posix -- | Filename extension for executable files (including the dot if any) -- (usually @\"\"@ on POSIX systems and @\".exe\"@ on Windows or OS\/2). exeExtension :: String -exeExtension = (#const_str EXE_EXTENSION) +exeExtension = EXE_EXTENSION
