Hi, I compile my code with GHC on Linux, and don't have ready access to a Windows or a Mac operating system. Is it possible to use the GHC LLVM backend as a means to cross compile Haskell code to target multiple operating systems? I had envisaged it possible to generate the LLVM IR using GHCs -keep-llvm-files flag, and using LLVMs target triple flag to specify the CPU architecture and operating system of the users machine. I'd like to compile on Linux, to target WIndows and Mac machines. Strangely I cannot find blog posts or tutorials online for cross-compiling Haskell with GHC via LLVM. Is it possible? Thanks, -- Rob

You'll have much the same challenges as cross compiling using fllvm as fasm. I'm not sure if cross compiling has been tested much aside from in the Intel -> Arm case. On Tuesday, June 10, 2014, Rob Stewart wrote:

In the past I have succesfully compiled with Windows build of GHC simply by using Wine. It might work for you as well. It worked surprisingly well and without a single problem at the time. I was using GHC 6.8.2 back then. -- Krzysztof On Tue, Jun 10, 2014 at 10:59 AM, Rob Stewart wrote:

Hi Not that this will get your hopes up, but my two cents... I have never been able to get wine to play along. GHC tends to fail when I use wine (exceptions, dll's that misbehave). Maybe it behaves better now. If you manage to make it work, please, let us know. I use hudson to recompile packages for multiple architectures, and windows gives me most of the headaches. If you use llvm's backend, I wonder what would happen the moment you use Template Haskell. I have just recently started to use the Android backend, and I expect problems. (But maybe I'm mistaken.) So far I use Windows in a VirtualBox VM. That approach (obviously) works. I'll celebrate the day when ReactOS works as a full replacement of Windows.

Interesting. On my Arch Linux with wine ver. 1.7.19 it seems to work nicely, at least for simple cases. To test it I have just installed latest Haskell Platform, then upgraded cabal-install to latest version and finally I run sandboxed Yesod installation. All appears to be ok. Everything is seem to be slower, compared to native Linux, but that is a minor issue and rather expected. I would expect some building problems with native libraries, but this is always more problematic than just plain Haskell builds. -- Krzysztof On Fri, Jun 13, 2014 at 12:10 PM, Ivan Perez wrote:
