Hello, I've had a problem with GHC.Prim when compiling the darcs HEAD lately. When I compile it in the normal way with no special options
sh boot && ./configure && make && make install
it compiles correctly, but if I attempt to compile
module Main where
import GHC.Prim
main :: IO () main = return ()
then I get this output:
$ ghc --make Main.hs -fglasgow-exts -v Glasgow Haskell Compiler, Version 6.7.20070524, for Haskell 98, compiled by GHC version 6.7.20070524 Using package config file: /usr/local/lib/ghc-6.7.20070524/package.conf wired-in package base mapped to base-2.1 wired-in package rts mapped to rts-1.0 wired-in package haskell98 mapped to haskell98-1.0 wired-in package template-haskell mapped to template-haskell-0.1 Hsc static flags: -static *** Chasing dependencies: Chasing modules from: Main.hs Stable obj: [] Stable BCO: [] Ready for upsweep [NONREC ModSummary { ms_hs_date = Sat May 26 01:11:06 EST 2007 ms_mod = main:Main, ms_imps = [] ms_srcimps = [] }] compile: input file Main.hs Created temporary directory: /tmp/ghc19188_0 *** Checking old interface for main:Main: [1 of 1] Compiling Main ( Main.hs, Main.o ) *** Parser: *** Renamer/typechecker:

Is there anything I should be doing to make this work? Thanks for any advice, Ben

It works for me, with last night's HEAD build. Are you running GHC from the build tree, or installing it first? (not that it ought to make a difference). If you say 'ghc-pkg describe base', does it list GHC.Prim as exposed? While importing GHC.Prim should work, the right way is to import GHC.Exts instead. Cheers, Simon

I built a clean HEAD from today and installed it with 'make install'. It works well enough to compile libraries like zlib and binary as well as applications like xmonad. When I try to compile the example file Ben gave using the installed ghc, it fails as Ben described - no GHC.Prim. 'ghc-pkg describe base' does not list GHC.Prim as exported, even though base's cabal file does. When I use the GHC from the build tree, it compiles fine.

GHC.Exts doesn't appear to export unsafeCoerce#, which hs-plugins and gtk2hs both want.

I'd like to point out one other major application which depends on the availability of GHC.Prim: GHC (As of 20070518) GHC HEAD cannot compile itself for exactly this reason. Stefan

I tried again with a source tree fresh from "darcs get --partial" and got the same result as before. "ghc-pkg describe base" doesn't mention GHC.Prim, but it does mention GHC.PrimopWrappers, I don't know if that's helpful. The documentation for GHC.Prim does get built. I wouldn't think it would matter, but I'm compiling with GHC 6.6 from Debian, which does have GHC.Prim exposed in the base package. Thanks, Ben

We know what the problem is - GHC.Prim is being filtered out of the module list during installation. Ian is working on overhauling binary distributions, and will fix this at the same time. Cheers, Simon
