Hi,
find ghc's generated settings file. What FPU is used there?
Thanks, Karel

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

Anyone else building GHC on a pi?

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-...).
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
