I may be wrong here, but I think what is meant is not that it replaces foo.o with foo-xen.o by renaming foo.o in the filesystem, but rather that the file listed in the variable obj is renamed, and thus it wants to build foo-xen.o instead of foo.o, and use it for linking. To build foo-xen.o, you'd obviously need a foo-xen.[cS] file as a source-file... I gues Christian (or someone else who actually knows how it works) can either confirm this, or tell us how it works. -- Mats > > Thanks. > Jun > > _______________________________________________ > Xen-devel mailing list > Xen-devel@xxxxxxxxxxxxxxxxxxx > http://lists.xensource.com/xen-devel > > > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
