Damn it. So close. I don't know how make install succeded without

Sigh! Go back to your build tree and try the same thing with
inplace/bin/ghc-stage2 and let us know if this works or not. BTW:
What's in Main.hs?

Hello World.
The stage2 compiler works fine inplace.
OK, so binary-dist not only corrupted your settings file, but also somehow
your compiler. Nice to see you are able to get working compiler on your RPi
board. Congratulations! :-)
Thanks. :)
So the binary-dist has a settings.in file. It is the configure step in the
binary-dist that generates the corrupt settings file.
I'll try to poke around to see where and why the stage2 compiler and the
binary-dist compiler differ.
I replaced the lib/ghc-7.6.1/settings built from the binary-dist which
read:
[(GCC extra via C opts, -fwrapv),
(C compiler command, /usr/bin/gcc),
(C compiler flags, -fno-stack-protector ),
(ar command, /usr/bin/ar),
(ar flags, q),
(ar supports at file, @ArSupportsAtFile@),
(touch command, touch),
(dllwrap command, /bin/false),
(windres command, /bin/false),
(perl command, /usr/bin/perl),
(target os, OSLinux),
(target arch, ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI =
HARD}),
(target word size, 4),
(target has GNU nonexec stack, False),
(target has .ident directive, True),
(target has subsections via symbols, False),
(LLVM llc command, llc),
(LLVM opt command, opt)
]
With the settings file from the build:
[(GCC extra via C opts, -fwrapv),
(C compiler command, /usr/bin/gcc),
(C compiler flags, -fno-stack-protector -Wl,--hash-size=31
-Wl,--reduce-memory-overheads),
(ar command, /usr/bin/ar),
(ar flags, q),
(ar supports at file, YES),
(touch command, touch),
(dllwrap command, /bin/false),
(windres command, /bin/false),
(perl command, /usr/bin/perl),
(target os, OSLinux),
(target arch, ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI =
HARD}),
(target word size, 4),
(target has GNU nonexec stack, False),
(target has .ident directive, True),
(target has subsections via symbols, False),
(LLVM llc command, /usr/bin/llc-3.0),
(LLVM opt command, /usr/bin/opt-3.0)
]
and now ghc builds executables that do not segfault!
It seem that the configure program in the binary-dist needs some patching.

Looks like you do have corrupted settings file. Recover it by adding
HARD following armABI = , so result should be:
ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI = HARD}
That's all what's needed, honestly speaking I don't know why it's

Re: Error building ghc on raspberry pi.
Good! So the patch I already provided is working fine at least w.r.t. change in configure. I've tested it here on my raspbian chroot on pandaboard where I've hacked config.guess to print exactly what you get on real rpi. Now, I'm curious if the hack in DriverPipeline.hs helps too. Were you able to merge the patch into your GHC? And rebuild? What was the result?

I've ben getting a lot of errors about two occurances of the float-abi=hard flag. You should not IMHO. My patch should solve all your issues. :-) The only issue you may get is that your distro ghc will compile for soft-float ABI and your compiled GHC will compile to hard-float and object files will get mixed somewhere. But I trust your distro ghc builders that this is not the case so both GHCs should compile using hard-float. So issue solved, at least should be. Now I'm just waiting if you verify this or not so I'm either able to submit the patch for inclusion or hack it more...

Re: Error building ghc on raspberry pi.
Well, if you make some board available in DMZ I'm certainly interested to run at least configure on it from GHC HEAD to see what we need to hack in order to add support for RPi into GHC HEAD. Unfortunately GHC HEAD is now in a wrong state w.r.t. LLVM based build, but Austin is working on this. I think I can hack support for RPi in the meantime for testing later on fixed GHC HEAD LLVM build...

Re: Error building ghc on raspberry pi.
Well, just wild guessing what's needed on RPi, but could you who do have this board attempt to use attached patch? Don't forget to ./boot as this change configure. Also testing it on completely clean tree may be wise idea. Also after configure run please check that you do have VFPv2 in the ext list. -- this is indeed a wild guess for ARMv6, but as we do the same for ARMv7 (guessing VFPv3) I don't think this is show-stopper now...

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:

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`
