# Based on Simon Marlow's port script for FreeBSD:
# $FreeBSD: ports/lang/ghc/Makefile,v 1.13 2002/08/22 12:53:38 obraun Exp $
# And on NetBSD's 5.04.3 .hc boot script

ONLY_FOR_ARCHS= i386 amd64
#                   sparc
 
# The general solution for other architectures will be to boot
# via unregisterised .hc files generated on openbsd-*-i386. See:
#
#  http://haskell.org/ghc/docs/latest/html/building/sec-porting-ghc.html
#
# The best bets are powerpc and alpha. sparc64, mips64 and amd64
# should work. hppa and mips have recently worked. m68k hasn't worked
# for a long time now, and on mac68k at least _ld_ dies with a malloc
# error when linking the ghc binary.
 
# The build process: we build a full GHC from C source. The C source
# needs to be generated once for each arch, for each version of GHC.
