Building HEAD with -fasm: error in package 'unix'

[wld]

Hi,

I have built GHC HEAD yesterday.
My build.mk is:

GhcCompilerWays =
GhcRTSWays = thr
GhcLibWays =

SRC_HC_OPTS = -O
GhcHcOpts = -O
GhcLibHcOpts = -O

Options -O and -fvia-C have separated recently.
So libraries and the stage2 compiler were compiled
by the native code generator. The build finished
without any errors, but the following command failed:

$ ./compiler/stage2/ghc-inplace --interactive -package ghc

Loading package unix-1.0 ... linking ... ghc-6.7: unable to load
package `unix-1.0'

I think, the reason  of this error is that 'lstat' is a macro but the native
generator do not look into C headers to find a real name.

Re: unsafeCoerce#

Hi,

Finding unsafeCoerce# in the documentation is challenging at best.
It's not indexed by Haddock, which in turn means its not indexed by
Hoogle. Lambdabot doesn't find it. Googling gave me GhcExts (from an
old Happy file), which I guessed at GHC.Exts.

Someone in #haskell suggested GHC.Base. I'm not sure where I should
import it from, but it would be nice if the docs included it
somewhere.


Hi, GHC.Prim module say at the end of its export section:

-- * Coercion
-- |@unsafeCoerce\# :: a -> b@ is not a primop, but is defined in MkId.lhs.

In MkId.lhs , see \subsection{Un-definable}

HTH,

Re: One-character bug in time library

Sorry ;)

Hi,

File package.conf.in (darcs GHC HEAD) contains
the following line:
  hs-libraries:   "HSTime"

This should be of course
  hs-libraries:   "HSTime"


Certainly,
  hs-libraries:   "HStime"

GHC as library and new build tree layout

[wld]

Hi,

I have tried Lemmih's example of using
GHC as library. The very first line

 Prelude> :m GHC

failed. Searching for reason of this failure, I've
looked into the package.conf.in file of package ghc
and found that pragma import-dirs contains lines like

import-dirs:   FPTOOLS_TOP_ABS"/ghc/compiler/stage2/utils",
  FPTOOLS_TOP_ABS"/ghc/compiler/stage2/basicTypes",

It looks like an artifact of the old layout. I've
removed "/ghc" from all those lines, re-registered package
ghc - example worked!

Is that the right way to go?

Head GHCi fails to load package unix

GHC built from Darcs head fails to load the package 'unix'.

The small test of using 'lstat' compiles and links fine
with 'ghc-inplace --make'.
