[sorry for the dups, third try w/ fedora-devel-list subscribed]

Hi Lennert,

Referring to your post at http://www.redhat.com/archives/fedora-devel-list/2007-October/msg00045.html

Thanks a lot for posting those rpms. I was able to use those with --define='cross_target ia64-linux-gnu' to build a cross-compiler that builds xen-unstable.hg including the userland tools. I posted that information today to the xen-devel mailing list, see http://lists.xensource.com/archives/html/xen-devel/2008-01/msg01105.html

I had to make some changes, first to build the gcc rpm successfully on x86_64 targetting ia64, and second to include some files that were missing. The missing files were due to %ifarch tests which were looking at the build arch instead of the target arch. I came up with a solution for that... though I wouldn't be surprised if you're able to come up with something more elegant.

The patch is below. Thanks again for your work which enabled me to get this running.

Aron
