I'm trying to cross-compile GHC as follows:

IMHO, you shouldn't go that way, because it adds much more complexity than you already have with OpenBSD as host *adn* target. During my last tests back in december, not even OpenBSD/i386 -> OpenBSD/i386 worked with .hc files. That should be fixed first. Then, something like OpenBSD/i386 -> OpenBSD-amd64 (and vice versa) should be done. And if this works, it's questionable wether one should work on cross building with .hc files using differen host an target operating systems or wether it would be more useful to start getting GHC running on other OpenBSD archs.
I follow the guide at: http://hackage.haskell.org/trac/ghc/wiki/Building/Porting
I downloaded the last stable source tarball (ghc-6.12.1-src.tar.bz2), then ran the following commands:
export AUTOCONF_VERSION=2.62 export AUTOMAKE_VERSION=1.9 cp /bin/pwd utils/ghc-pwd/ghc-pwd sh boot ./configure --enable-hc-boot --build=i386-unknown-openbsd --host=i386-unknown-openbsd --target=i386-unknown-openbsd [...]
IIRC there where some discussions (or even patches pushed?) about the build/host/target combo, so you may try to pull ghc sources with darcs (head or the 6.12 branch).
The latest fails, with the following trace: http://pastebin.ca/1770926
The following errors are quite interesting: includes/stg/Types.h:103:2: #error GHC untested on this architecture: sizeof(void *) != 4 or 8 includes/rts/Constants.h:156:2: #error unknown SIZEOF_VOID_P
Your build is (re)creating includes/ghcautoconf.h -- this looks very wrong to me, since ghcautoconf.h is supposed to be created by a former configure / make bootstrapping-files on the target platform and then used on the host for creating the .hc files. Ciao, Kili
