Thanks for the advice; However, it had little effect.
I now have the errors:

Anyone else building GHC on a pi?

I believe I had the same problem, which disappeared after upgrading llvm from

Hope this helps,

Thanks, using LLVM 3.1 seems to have improved the siutation, but I'm running
into a new error.
Here is the error I get when trying to build GHC 7.6.1 from 7.4.1

I get similar errors when building GHC 7.4.1 (patched with
http://hackage.haskell.org/trac/ghc/attachment/ticket/5914/0001-add-support-for-ARM-hard-float-ABI-fixes-5914.patch).
Any of you encountered this problem before?
Yeah, I had a lot of these. The problem was that GHC has a lot of different
"CFLAGS",
so finding the right way to pass "-float-abi=hard" to every one of them took
some time, but
eventually I ended up with the following change to mk/build.mk:
ifeq "$(BuildFlavour)" "quick"
SRC_HC_OPTS = -H64m -O0 -fasm
GhcStage1HcOpts = -O -fasm
GhcStage2HcOpts = -O0 -fasm
GhcLibHcOpts = -O -fasm -optlc-float-abi=hard
SplitObjs = NO
HADDOCK_DOCS = NO
BUILD_DOCBOOK_HTML = NO
BUILD_DOCBOOK_PS = NO
BUILD_DOCBOOK_PDF = NO
endif
(Change the build flavor you are using, of course)
And I ran configure as:
LDFLAGS="-marm -mfloat-abi=hard -mfpu=vfp" CFLAGS="-marm -mfloat-abi=hard
-mfpu=vfp" ./configure --with-opt=/usr/bin/opt-3.1 --with-llc=/usr/bin/llc-3.1
--with-ld=`which ld.gold`
(I switched to the gold linker, because ld was running out of RAM often.)
I did eventually finish building stage2, but the final executable segfaulted on
start.
I haven't investigated much why that happened, the days it takes to rebuild it
just
made me give up.
Hope this helps,
Thijs
