Well, sorf-of. A few extra unobvious parameters and workarounds are required in each case, but it's doable, (arguably) simpler than real cross-compilation and already exhibits problems that real cross-compilation may in some circumstances face. Wiki pages (kudos to all previous authors): http://www.haskell.org/haskellwiki/GHC_under_Wine https://ghc.haskell.org/trac/ghc/wiki/Building/Compiling32on64 Examples of both kinds of binaries, for a project with gtk2hs and TH dependency: https://github.com/LambdaHack/LambdaHack/releases/tag/v0.4.99.0 Please share your success reports here or on the wiki and let's exchange ideas, file concrete tickets and propose patches to make the two processes more accessible. Some tickets are mentioned in the wikis or can be traced from there, but there may be others I'm not aware of, so let's link them where appropriate. Hope this helps somebody, Mikolaj
