Hi Eric, Are you building on a Panther or Tiger system? I would only expect this to work on a Tiger system. Have you modified any other components with DarwinBuild prior to building xnu? If you want to do a ppc-only build, you can edit the RC_ARCHS environment variable in the same manner as I described in: <http://www.opendarwin.org/pipermail/darwinbuild/2005-November/ 000180.html> However, I don't think your problem is related to building universal binaries. - Kevin On Nov 5, 2005, at 11:55 AM, Eric Kuch wrote:

I have gotten to step 3 correctly, then when i type "darwinbuild xnu" it works but then it fails, will you please tell me what is going wrong with it? i think it has somthing to do with the RC_ARCHS if you can tell me how i can change that so its only PPC, i would be very thankful.
