[Xen-ia64-devel] MiniOS on ia64

[Dietmar Hahn <dietmar.hahn@xxxxxxxxxxxxxxxxxxx>]

Hi Samuel,

MiniOS on ia64 is currently broken and I would get it compile again.
Beside some other problems I found the app.lds thing.
This doesn't work on ia64 because the special object mini-os_app.o is not 
linkable with the other objects.
What is needed is a object got compiled with the ia64 flags and than linked 
with app.lds script.

A simple solution could be to add an empty file maybe app_lds.c to the mini-os 
main directory. This will be compiled with ia64 flags and than linking it 
with app.lds.
The diff for the Makefile would be:

I didn't find any solution in changing your linker script app.lds to get the 
needed flags into the object mini-os_app.o to get it linked with ia64 
objects.
What do you think?
Thanks.

Dietmar.
