Hi, [1] describes how to use hgettext with cabal. When running "runhaskell Setup build" this works fine. But "cabal build" says: Not in scope: `__MESSAGE_CATALOG_DOMAIN__' Not in scope: `__MESSAGE_CATALOG_DIR__' [1] says: "__MESSAGE_CATALOG_DOMAIN__ and __MESSAGE_CATALOG_DIR__ are macro definitions, whose hold configured strings from the Cabal." Why "cabal build" does not expand these macros? Thank you. [1] http://www.haskell.org/haskellwiki/Internationalization_of_Haskell_programs
