Hi Brandon Thank you for reply. Could you please tell me how to install dph because cabal install is not working with ghc-7.4.0.20111219 and I have issue with ghc-7.2.1 and dph Macintosh-0026bb610428:src mukesh$ ghci -Odph -fdph-par on the commandline: Warning: -O conflicts with --interactive; -O ignored.

I have installed ghc-7.4.0.20111219  and this announcementhttp://www.haskell.org/pipermail/glasgow-haskell-users/2011-December/...says that "The release candidate accidentally includes the random, primitive, vector and dph libraries. The final release will not include them". I tried to compile  a program

It says they accidentally included extra libraries; not that they accidentally built the DPH extensions to the compiler.

I don't know so much about ghc-7.4, but if "loading dph codes in ghci" is the main matter here, below might help: http://warmfuzzything.posterous.com/loading-dph-codes-in-ghci Best, -- Atsuro Hoshino On Sun, Jan 22, 2012 at 2:58 AM, Brandon Allbery wrote:

Sorry, but I don't know.  I don't follow or use DPH, I just know how the GHC repo works, and that they had a problem with including additional library sub-repos which just happened to include (probably out of date, since DPH is developed separately) DPH libraries.  As such, I would not expect DPH to be included in the official 7.4 release unless the DPH folks submit an updated version (and probably not even then since GHC is in the release candidates phase, so it's a bit too late to add a newer DPH into it).
