GHC 6.2.1 under darwinports

[Gregory Wright]

Hi,

The Glasgow Haskell Compiler supported under darwinports has been
bumped to version 6.2.1. By default, GHC now builds with OpenGL support.
The build should work for both OS X 10.2.x and 10.3.x.
This lets Mac OS X jaguar users to get the latest version
of GHC, as Wolfgang Thaller's binary release is only tested with 
panther.
It can also provide amusement for those who just like to build from 
source.

For information on getting darwinports, see 
http://darwinports.opendarwin.org.

Best Wishes,
Greg Wright

RE: [Haskell] deriving with newtypes

[Simon Peyton-Jones]

[Redirecting to GHC users.]

This seems like a very reasonable point.   Not possible today, but it
should be.  It'll go on my to-do list.  Meanwhile, I guess you can
always do it by steam.

| Hello,
| 
| I'm trying to use GHC's deriving mechanism for newtypes in the
following way:
| class C a b
| instance C [a] Char
| newtype T = T Char deriving C [a]
| Unfortunately, this isn't possible. Is there a reason for this? Can I

Could you send us enough code to reproduce the bug?  The smaller the
better, but don't worry if you can't reduce it.

Cheers,
Simon

Bug report.

[MR K P SCHUPKE]

Started getting:

ghc-6.2.1.20040313: panic! (the `impossible' happened, GHC version 6.2.1.20040313):
mkTyVar a1 {- tv a75q -}

Please report it as a compiler bug to [EMAIL PROTECTED],
or http://sourceforge.net/projects/ghc/.

today... definitely a but to do with class inference, as it started appearing
aftyer changing some instance constraints and fundeps on classes.

Can't really be a lot more specific as code is big. Let me know if you want
me to produce a small code extract which triggers it.

Regards,
Keean.
