We have 2 patches. One to fix compilation of OpenAL:
http://haskell.org/~gentoo/gentoo-haskell/portage/dev-lang/ghc/files/ghc-6.4.1-openal.patch
(I know this is fixed in darcs, I've not checked cvs ghc-6.4-branch)
I'm waiting for feedback from Sven on that one.
The other to allow us to enable/disable building the X11, HGL packages:
http://haskell.org/~gentoo/gentoo-haskell/portage/dev-lang/ghc/files/ghc-6.4.1-configure.patch
(this is so we don't get untracked deps on X11, eg when building on one
machine and installing on another)
I've committed those.
The next fix is probably not appropriate for everyone. It's to allow ghc
to work with a "hardened" version of gcc, basically by turning off the
hardened features (since they upset the mangler). It's not suitable for
everyone because not all distros use a gcc that has the hardened
features and such gcc's would not recognise the -fno-blah flags.
We have a temporary fix for:
http://hackage.haskell.org/trac/ghc/ticket/703
which is to use -opta-Wa,--noexecstack in SRC_HC_OPTS, -Wa,--noexecstack
in SRC_CC_OPTS and -opta-Wa,--noexecstack in the ghc wrapper script.
We currently don't support building the pdf docs because there is a bug
in the latest version of libxslt that makes xsltproc segfault when
processing the docbook stuff.
http://bugs.gentoo.org/show_bug.cgi?id=106992
http://bugzilla.gnome.org/show_bug.cgi?id=316861
Looks like you should keep these as local patches for now.
We found that using -fno-warn-deprecations in SRC_HC_OPTS fixed the
wierd "tee: write error" issues we had when logging the build process.
probably accidental.
There's some wierdness with ArSupportsInput. I'm not sure if that still
applies.
We have some arch-specific defaults for wether to enable certain ghc
features. I think these would be suitable defaults for everyone:
alpha, hppa and ppc64 should use GhcWithInterpreter=NO
This corresponds to the current default except for ppc64. Does GHCi not
work on ppc64? (I don't see any ppc64-specific stuff in rts/Linker.c,
so maybe).
alpha, and hppa should use GhcUnregisterised=YES
I've added these defaults.
alpha, hppa, ppc, ppc64 and sparc should use SplitObjs=NO
This corresponds to the current default except for sparc and powerpc.
What's the problem with those?
Cheers,
Simon
