Comment 2 Sergei Trofimovich gentoo-dev 2016-05-31 21:41:11 UTC
ghc-8 has basic support for ppc64 NCG and improved cross-compiling support.
Should be feasible to bootstrap ghc binaries there.
Comment 3 Sergei Trofimovich gentoo-dev 2017-04-08 21:51:09 UTC
cross-building was substantially improved in ghc-HEAD this month.
I hope to get full cross-compilation support for upcoming ghc-8.2.1.

It will ease initial porting of ghc to any new arch with a few
crosdev/emerge-${CTARGET} commands.
Comment 4 Leno Hou 2017-04-09 09:15:59 UTC
Thanks Sergei Trofimovich for you effort on this cross-building.
Comment 5 Scott Howard 2020-01-02 20:10:59 UTC
The cross-building system is broken for me. I read the following guide and used crossdev with CTARGET=powerpc64le-unknown-linux-gnu:
https://trofi.github.io/posts/200-ghc-as-a-crosscompiler-update.html

I used the overlay repo (https://github.com/gentoo-haskell/gentoo-haskell) for this output but the standard repo also has the same issue with ghc-8.4.3.

I encountered the same error as this while cross-compiling from my x86_64 laptop:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=910664#10

Any insight about the best way to get ghc-8.2.1 or later working on ppc64le will be appreciated.

Comment 6 Scott Howard 2020-01-05 17:21:20 UTC
I have a more thorough report to amend the previous one. The previous error was from memory starvation. Now using the same commands (but reducing parallelism and adding more swap) I am able to successfully build the cross-ghc. The cross-ghc now runs into a linker error that I cannot solve.

full build log where cross-ghc fails to build target (ppc64le) ghc
Comment 8 Sergei Trofimovich gentoo-dev 2020-01-09 07:32:55 UTC
I suggest also using USE=ghcmakebinary flag. That might make bundled libffi building less problematic.

Hm, that is unusual. Is it a reproducible failure or a one-off bug? I'll try locally as well.
Comment 9 Sergei Trofimovich gentoo-dev 2020-01-09 22:53:12 UTC
Tried to bootstrap ghc-8.8.1 into ppc64le today and it built the package just fine:
    https://slyfox.uni.cx/distfiles/cross-ghc-bin-8.8.1-powerpc64le-unknown-linux-gnu.tbz2

I'll try to dump it onto ppc64le machine and see if i can bootstrap native 8.8.1 on it and then 8.6.5 from it.
Comment 10 Scott Howard 2020-01-10 18:40:43 UTC
I get the linker error every time. I wish I knew what was causing the issue with my cross build environment.

That being said, your binary package gets me over the main hurdle. I was able to use that as the arch_binary in my local 8.8.1 ebuild and ghcbootstrap my own 8.8.1 on top of that. I might use what I have now to go back to 8.6.5 but 8.8.1 works just fine. Thanks for revisiting this!
Comment 12 Fredrik Noring 2020-02-09 12:56:53 UTC
Thank you Sergei, this was very helpful. I managed to install your dev-lang/ghc-8.8.1. However, there is some kind of problem with app-admin/haskell-updater-1.2.10:

Comment 13 Sergei Trofimovich gentoo-dev 2020-02-09 13:59:36 UTC
Yeah. Note: ghc-8.6.* and ghc-8.8.* are not yet keyworded on any ARCH in gentoo. There will be quite a bit of breakage. We usually recommend trying ::haskell overlay for beleeding-edge software until it's moved to ::gentoo.

ghc-8.6.5 should be less broken, but still not perfect.
