[Bug 70302] Re: no ghci in edgy (regression vs dapper)

[John Steele Scott]

I know this is pending on upstream & Debian activity, but just for the
record this bug is still current on gutsy/powerpc.

[Bug 70302] Re: no ghci in edgy (regression vs dapper)

[Isaac Dupree]

As long as GHC has no registerised-powerpc maintainer (which I believe
is still true), and ghc bug #631 remains unfixed
 (even if it is fixed in
GHC 6.8, that won't be out in time for Gutsy, but 6.8 will be in time
for gutsy+1), I don't think this bug is going to be fixed.  I think the
best bet is to hope for #631 to be fixed soon, then let the Debian
packagers turn on GHCi for the unregisterised architectures, and (if I
understand the process correctly) Ubuntu can then inherit those changes
from Debian as soon as practicable.

Although, I'm not sure how important "bootstrap issues with [(some
particular)] older ghcs" are as time passes, in debian-ish environments,
(and I'm not using ubuntu anymore either (for one thing, the two
projects' release cycles and practices help Ubuntu be chronically behind
by one on the newest GHC release...))

Hey folks.  Is anyone still hoping to do something about this issue?  Or
should we mark it as "won't fix"?

Hi,

ghc6 on powerpc is not built registerized:
"Removed powerpc from the list of arches to do a registerised build with object 
splitting as there are bootstrapping issues from earlier GHCs." (Ian's 
changelog entry, 6.4-3).

You can also find this out by looking at debian/rules of the
sourcepackage (line 39 and below).

I personally don't have access to a powerpc box, so I didn't change
anything on that front (also I'm more than happy, that ghc6 itself
actually works on all ubuntu arches).

If you know of a fix, or would like to help out in this matter, please
do. However changing from unregisterised to registerised for edgy also
won't work, since that would also mean that all haskell library packages
would need to be rebuilt.

Thanks,
 Stefan.

Rebooting into a copy of my OS from before upgrading from Dapper to
Edgy, I can reproduce the referenced ghc-bug-631.  So I see there is a
reason for this.  On the other hand, I didn't notice any problems when I
used ghci, personally...

It's powerpc -- but surely GHC is built registerised on that
architecture? (is there some way I can find out whether a given ghc
binary was built that way?)

Hi,

what arch are you trying to use ghci on? (I'd guess it's neither i386
nor amd64). If so, it's intended that there is no more ghci, due to
http://hackage.haskell.org/trac/ghc/ticket/631 .

Backporting ghc6.6 is not trivially done, the same comments I wrote on
bug #56516 apply here as well :(.

Cheers,
Stefan.

Oops, I meant runhugs -98, not +98 -- its flags are so confusing.  Probably 
this should be in a separate bug report somewhere, but, here is the messages I 
get for doing that the wrong way:
runhugs: Error occurred
ERROR "/usr/lib/hugs/libraries/Text/ParserCombinators/ReadP.hs":133 - Syntax 
error in type expression (unexpected `.')
