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...
I switched to using llvm-3.0 from rasbian, and made a lot of progress. (In retrospect I built llvm-3.1 using nix, and it was in a completely different toolchain than the rest of the build. I should have known that it wouldn't work).
Ehm, building LLVM on your own is always a risky business. See my blog[1] for more details especially find the post where I compare quality of various LLVM builds using various optimization options...
I was able to complete the build of ghc-7.6.1 using Karel's patch and
./configure --with-llc=/usr/bin/llc-3.0 --with-opt=/usr/bin/opt-3.0
I was able to make binary-dist after doing
mkdir compiler/stage2/doc
However after unpacking the binary distribution and doing a make install I get:
Installing library in /tmp/bindist/lib/ghc-7.6.1/ghc-prim-0.3.0.0 ghc-cabal: Failed to read "target arch" value "ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI = }" make[1]: *** [install_packages] Error 1 make: *** [install] Error 2
And in particular the installed ghc gives the error:
$ bin/ghc Failed to read "target arch" value "ArchARM {armISA = ARMv6, armISAExt = [VFPv2], armABI = }"
Sounds to me like Karel's patch is almost, but not quite there.
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 screwed on your board.
Karel, maybe you should try deploying a binary-dist on your panda board?
Sorry? What's "binary-dist"? And why I should do that? And what exactly do you mean by "deploying"? And on what OS? Ubuntu or Raspbian run in Ubuntu chroot?
What I'm suggesting is that if you want to try to reproduce my corrupt setting file error and ammend your patch for including in GHC, you should after making ghc-7.6.1 (or whatever version you are building) do a make binary-dist # this will product a ghc-7.6.1-arm-unknown-linux.tar.bz2 file extract ghc-7.6.1-arm-unknown-linux.tar.bz2 in some temporary directory. in that extracted directory run ./configue --prefix=<some temporary directory> make install
