Just thought I'd share a little hack... linux has a command 'setarch' which changes the current architecture so you can do things like build i386 rpms on a x86_64 system... by installing both a i386 and x86_64 ghc (both from the fedora repo work great) and replacing the ghc driver with something like the below makes ghc "just work" too. (replace paths as appropriate) I wonder if we should make the driver script a bit smarter in general to allow multiple versions of ghc normally so you can just pass a version and arch command line argument to ghc and the driver will intpret it and call the appropriate back end. #!/bin/sh case `uname -m` in x86_64) GHCBIN="/usr/lib64/ghc-6.4.1.20050626/ghc-6.4.1.20050626" TOPDIROPT="-B/usr/lib64/ghc-6.4.1.20050626" EXTRA_OPTS="" ;; i*86) GHCBIN="/usr/lib/ghc-6.4/ghc-6.4" TOPDIROPT="-B/usr/lib/ghc-6.4" EXTRA_OPTS=" -optc-m32 -optl-m32 -opta-m32 " ;; *) echo "Unknown architecture" ; exit 2;; esac echo $GHCBIN $TOPDIROPT $EXTRA_OPTS ${1+"$@"} exec $GHCBIN $TOPDIROPT $EXTRA_OPTS ${1+"$@"} -- John Meacham - ⑆repetae.net⑆john⑈
