The current Cabal used for building GHC has a small bug, it *always* creates
the data directory, even if there are no data files in the package. Simple
fix:
*** /tmp/Install.hs 2007-09-09 14:56:50.000000000 +0200
--- Distribution/Simple/Install.hs 2007-09-09 12:57:21.000000000 +0200
***************
*** 115,121 ****
(putStrLn ("directory " ++ haddockPref pkg_descr ++
" does exist: " ++ show docExists))
when (dataFilesExist || docExists) $ do
- createDirectoryIfMissingVerbose verbosity True dataPref
flip mapM_ (dataFiles pkg_descr) $ \ file -> do
let dir = takeDirectory file
createDirectoryIfMissingVerbose verbosity True (dataPref </> dir)
--- 115,120 ----
Nothing substantial, but this leads to lots of useless empty directories when
GHC is installed. Feel free to apply this fix in the right repository... (No
idea which)
Cheers,
S.
