( x86 being replaced with whatever architecture is the target ). This change comes for free if people reference the "scripts/Makefile.build" to create their kernel modules. However, in my case below, "scripts/Makefile.build" is not used. Thus the error ... wr -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of William Reich Sent: Tuesday, November 24, 2009 3:39 PM To: General Red Hat Linux discussion list; General Red Hat Linux discussion list; redhat-list@xxxxxxxxxx Subject: kernel module compile question on Fedora 11/12 Using Fedora 11 with all the latest patches, I am trying to compile a simple kernel module.
