Initial ghc-6.12 + hackage build results

[Duncan Coutts]

All,

I've tried building 1324 out of the ~1700 packages from hackage using
ghc-6.10.4 and ghc-6.12.0. This is the subset of packages that I could
build in one go.

Compared to the subset that I could build with ghc-6.10.4, I had to
chuck out 125 packages because their build dependency constraints
precluded them from building with ghc-6.12.

Of the remaining 1324 packages, 113 packages that built OK previously
now do not build.

Amongst that 113, the ones that cause most knock-on failures are:
(16,"packedstring-0.1.0.1")
(12,"MissingH-1.1.0.1")
(11,"syb-with-class-0.5.1")
(6,"uvector-0.1.0.5")
(3,"stringtable-atom-0.0.6")
(3,"bindings-common-1.3.4")
(3,"binary-strict-0.4.6")
(3,"base64-string-0.1")

packedstring fails because it needs base 4, but only says
"build-depends: base", so cabal uses its compatibility tricks and builds
it against base 3. It should specify "build-depends: base == 4.*".

I need to investigate MissingH further. It failed because a dependency
of its non-buildable test program was not found. That should not have
been a problem.

syb-with-class has type errors, I'm guessing due to changes in
template-haskell package

uvector does not compile because of the changes in GHC's Handle
implementation.

stringtable-atom now fails with a type error for reasons I don't quite
understand:
src/StringTable/AtomMap.hs:320:0:
    Occurs check: cannot construct the infinite type: a = (Int, a)
    When generalising the type(s) for `findMax'
Perhaps some change in a containers function?

bindings-common and c2hs fail because the CLDouble FFI type has been
removed.

binary-strict fails because the export of Control.Applicative.many now
clashes with a local definition.

base64-string fails because it sets -Werror in it's .cabal file (a
practise which has been banned for some time for just this reason).


Of the remaining 113:

2 failed at the configure step:
MissingH-1.1.0.1  -- this needs investigation, I smell a cabal bug
lax-0.1.0.0

52 failed at the build step (including those singled out above):

ivor-0.1.9		-- 'rec' now a keyword
loch-0.2		-- -Werror fail
nano-hmac-0.2.0		-- -Werror fail
nanocurses-1.5.2	-- package specifies non-existant config.h (which used
to accidentally pick up ghc's config.h) this happens because the package
needs to run ./configure but does not say so.
network-fancy-0.1.4	-- GHC Handle changes
pkggraph-0.1		-- Cabal lib API changes

The remaining 59 are knock-on failures, ie packages that depended on one
of the failed packages.
