Ah. I was about to checkin a replacement for System.Posix.Types (in base) that uses hsc2hs instead of autoconf. Will that cause a problem? I'm guessing that even the autoconf'd sources are currently bootstrapped on the host rather than the target, so maybe the changeover will make no difference?
I'm confused. I thought we copied the configuration from the target to the host as part of the bootstrapping process, but now I can't see how this is supposed to happen for HsBaseConfig.h. It looks like following the instructions in the building guide will result in failure if you try to cross-compile between machines with different word sizes, but I know I've done this in the past :-/ Ian, any idea how this is supposed to work? Anyway, to answer your question, using hsc2hs in System.Posix.Types will cause problems for bootstrapping GHC, yes, because we can't run hsc2hs on the target without GHC, but we can run configure. I suppose we could add a dependency on another Haskell compiler just to run hsc2hs, but that's a pain. Cheers, Simon
