RE: [Xen-ia64-devel] MSI-X problems compiling Xen-ia64-unstable

[Guilherme Chehab <guilherme_chehab@xxxxxxxxx>]

Yes, it was not an ia64 problem.

Patching up with the MSI defines solved the compilation problem. The includes 
in /usr/include/linux were from kernel 2.6.5 (version.h)  -- default in SLES9 
with sp2... Very old stuff indeed.

Those defines were not included on 2.6.18-xen either, I checked other machine 
that has more a recent kernel version (2.6.23) and the defines exists on this 
version...

thx for your support.
Guilherme
