Hello, Dietmar Hahn, le Tue 11 Nov 2008 09:47:18 +0100, a écrit : > This doesn't work on ia64 because the special object mini-os_app.o is not > linkable with the other objects. Ah, because it's empty, how odd :) Well I think it'd be better to just drop it from the link line. Here is a complete patch that seeems to work for me. Samuel Fix mini-os ia64 compilation - Move the gntmap.h include to let hypercall-ia64.h get lib.h's memcpy declaration. - Avoid nested function to avoid a trampoline. - Do not link mini-os_app.o when it is empty.
