trouble building ghc-7.4 on Fedora 18 (devel) ARM

[Jens Petersen]

Hi,

I have been struggling to build ghc74 on ARM (ideally with llvm3) on
Fedora 18 (the current development tree).

After applying 4 recent ARM patches from Debian the ghc-7.4.1 build gets to:

:
"inplace/bin/ghc-stage1"   -H32m -O    -package-name base-4.5.0.0

I gather that it builds on Debian so I am not quite why it is failing on Fedora.

To see if ghc-7.4.2pre is any better I tried building
ghc-7.4.1.20120416 too (without any ARM patches),
which gets a lot further, to using llvm:

I haven't tried HEAD yet though the results at
http://darcs.haskell.org/ghcBuilder/builders/kgardas-linux-arm-head/index.html
are not too encouraging.

Perhaps I will try building ghc74 on ARM without llvm first, and maybe
on Fedora 17 too?

Anyway thoughts on how to proceed?

Thanks, Jens

ps There is actually a proposal to make ARM a Fedora 18 Primary
Architecture - though personally I feel it is a bit too early yet - if
that happens then this would become a more serious problem, though I
know ARM is still not a Tier 1 ghc platform.
