Re: Cross Compilation

Hi Gabor, Thanks for the pointer. I think that we're going to focus our effort on getting the HaLVM to work as a cross compilation target for GHC, and possibly working on getting the threaded runtime working with Xen. Is there a wiki page that describes your current path forward on getting TH working with a cross-compiler? Thanks! --trevor On Wed 03 Apr 2013 01:43:16 PM PDT, Gabor Greif wrote:

Hi Trevor,

I have Cross+TH on my agenda, but not sure I can start that task before 2013-05-31.

Here is a suggestion how to proceed, Stephen basically agreed that is it a workable, albeit little elegant, plan: http://www.haskell.org/pipermail/ghc-devs/2013-March/000660.html

Cheers,

Gabor

Hi Everyone,

We're starting to update the HaLVM, which produces Xen binaries from haskell programs, to a more current version of GHC. Currently, we build a stage1 compiler manually, with some patches to the RTS, and trick it into thinking that it's actually stage2 so that we can use template haskell. Ideally, we would like to look at Xen as a cross compilation target, as that provides a bit of a better path for keeping up to date with changes in GHC.

After reading some of the documentation on the developers wiki about cross compilation, it wasn't clear if template haskell is usable by a stage1 compiler built where target is not host, is this still the case? If so, what sort of changes would need to be made to enable this, and is it something that we could contribute to?

Galois has a little time allocated for updating the HaLVM, and would like to position ourselves so that staying up to date with GHC releases is easier in the future :)

Thanks!
